[Music] i'm paige amora i work at y combinator i'm on our work at a startup team so we're the team that helps our portfolio companies hire for this event we'll do um three tech talks these will just be about a technical topic that the founders find interesting or a bit about their company as well and then we will have two quick pitches um to hear about other companies and then we'll initiate breakout rooms so with that let's go to jeff i'm going to talk for 5-10 minutes or so about the electric airplane industry and in particular energy storage i'm going to cover a few different areas first a little bit about the aerospace industry and the particular market segments that we're working on number two some of the main technology challenges and then some of the major uh opportunities in the energy storage space especially funding opportunities which i think will be relevant for early stage startup companies um and happy to take questions at the end um just briefly about us we went through yc in 2017 we're about 20-25 people uh we're based up in albany new york we're funded in addition to private uh investors by nasa the us department of energy the u.s air force and the u.s army as well very briefly the carbon footprint in the aerospace industry is is very very bad um you would have to eat vegetarian for over a year to offset the carbon from even a single relatively short round-trip flight we focus on electric uh solutions to the aerospace industry because um there's a bunch of research that's come out that um other different technologies involving combustion things like biofuels or electro fuels or even hydrogen combustion um when stacked up against um jet fuel aren't even you know necessarily that much better and electric technologies have the potential to be substantially lower in total greenhouse gas emissions um so what this chart looks at is not only carbon but it looks at carbon nitrogen oxides contrails and a bunch of other things as well and tries to get to a total global warming equivalent and what you see is that you know in some cases combusting hydrogen is substantially worse um and you know electric is sort of uh in many ways the best environmental solution um when we looked at the aerospace industry we were you know surprised to see that when companies like boeing announced a new airplane that has let's say a 15 improvement in fuel burn compared to a previous airplane a lot of the underlying benefits come from engines so for example the 787 which had a 15 fuel burn benefit over the 767 a lot of that came from propulsion technologies we then looked at the aerospace industry we thought wow there's a lot of people working on relatively small airplanes but unfortunately small airplanes smaller than 100 passengers represent smaller than five percent of the carbon footprint of the entire aerospace industry and in fact actually most of the carbon footprint of the aerospace industry is airplanes larger than 100 passengers and in particular in what's called the narrow body segment so that's the seven three sevens the seven uh the a320s a typical airplane like you might be on carries sort of 100 to 200 passengers and so that's the industry that we work in um for you know for for sort of the business development people on this call we're this is an enormous market uh these are companies that are each worth 100 billion dollars um there are expected to be 30 000 new narrow body airplanes purchased over the next 20 years billions and billions of dollars of jet engine sales per year and billions of gallons of jet fuel so this is a large potential market opportunity if you could create the underlying technology and so what's needed number one propulsion and number two energy storage propulsion essentially being ultra lightweight engines energy storage of ultra lightweight ways to store electricity so this is our um uh electric engine that we built uh it's basically meant to be a replacement of a jet engine of a narrow body class airplane so it's a couple megawatts in power which is about 3000 horsepower substantially more powerful than anything that's out there in the aerospace industry in-house developed inverter designed for high altitude operations just finished some testing at the faa technology center and planning for um faa part 33 certification in the 2025-2026 time frame so that's kind of a little bit about what our company does what we're planning to do as our next step is we're taking a 100 passenger airplane and we're removing one of the four engines and replacing it with our electric engine to make it essentially an electric test bed so this is one sort of quick point to the group if anybody is working on propulsion technologies and is looking for a relatively inexpensive way to do testing please reach out to us because we're already going to have this platform in place i mean we're happy to do testing with you if you're working on technologies like this um the nice thing about this airplane is it's a four engine airplane but it can actually fly on three of the four engines so we're using basically one of the four engines as a um as a laboratory in the sky um i want to talk now a little bit about energy storage requirements um so no lithium ion battery is going to get to you know greater than 750 watt hours per kilogram um typically um you know lithium ion battery best case scenario is going to get up to 400 450 500 sort of absolute best case scenario so you really need to be looking at new chemistries and what what this industry is really looking for is even above a thousand watt hours or 1500 you also need high c rates you need relatively high discharge it doesn't have to be as high as the vertical takeoff and landing airplanes but you know sort of three to five uh c's uh also has to be altitude capable and in terms of energy storage what you really need is electricity you don't necessarily care if it's a battery so the two different technologies that have been mostly in development are sort of energy carrier technologies and then one quick note if you look on the right this is essentially the energy profile so you have a huge amount of power um up front during takeoff and climb out and then you have about a third of the power needed during cruise and this is a similar path so you see a huge spike in power needed right here and then it sort of drops off for the power that's needed it's about you know a third to a quarter of the power needed so two different major technologies under development and this is what we would encourage people in this group to work on i'm very happy to talk about this with people later number one aluminum air fuel cells or other metal air chemistries and number two hydrogen fuel cells so in terms of aluminum air aluminum air is is generally in the category of other metal air chemistries zinc air for example has been used in hearing aid batteries since the 1970s forum energy is a company that's raised about 300 million dollars maybe even more than that um to focus on an iron air battery so it's a new chemistry that's sort of it's it's something it's old but it's new a lot of people are working in this space and actually at the most recent us department of energy rpe summit in uh earlier this year there was specifically um a group that was talking about putting together uh funding related to this topic the disadvantage of this is that you can't uh recharge these batteries uh you have to recharge them uh by taking them you can't recharge them by plugging them in you have to recharge them by sending them back to a facility so there's a lot of operational challenges with this but at the same time it's a major advantage um i just have two more slides a lot of people are also working on hydrogen fuel cells obviously everybody knows what a hydrogen fuel cell is but there's a lot of applications potentially in the aerospace industry and um people are looking at technologies that could be greater than a power density of two kilowatts per kilogram by 2030 and that's sort of what a lot of people think of as the number that's needed for large aerospace applications so if you're working for example on ultra lightweight fuel cells aerospace is a great industry for you to be in the last thing i want to say in this space is there's a lot of money going into the space right now so you know everyone wants to go get venture capital money as i mentioned form energy has raised a whole bunch of money in this space but here's just four different opportunities or three different opportunities that are sort of live opportunities to raise money if you're in europe there's the clean skies i think they've put up 700 plus million euros work in this space um ati fly zero is a program out of the united kingdom the us department of energy is doing a lot of work and then there's obviously other things as well so we think this is a strong space because it's a huge potential market there's a lot of money going into the space and major opportunities to revolutionize the us aerospace industry so i'll pause there i wanted to keep this speech relatively short please feel free feel free to reach out to me um take down the email address i'm not going to be able to stay for a breakout session but if folks want to schedule one-on-one call um happy to do so so thanks very much for the opportunity you have a couple of questions here in the chat um how were your relationships with the doe in the air force established oh great question um you know so uh let's see we've had um a few different contracts with nasa a few different contracts um with the air force and with the army um some of them are sort of serendipity nasa puts out a request for a proposal and it's exactly the thing um that you're working on and that's a sort of luck but you know it occasionally does happen um but sometimes also you you these organizations have open solicitations so for example with the air force um we're we're we're being funded now to turn on to an ultra lightweight generator for them and that came about because we found a unit within the air force that was looking for an ultra lightweight generator we said hey we could we could do that for you um and then we sort of put together a proposal together so i would say it's um maybe the short answer is um some uh advice that uh that i was given during the yc batch sort of try everything you can think of and then try it again and then try it again and try it again um so it's you know it'd be nice to say like oh it's just an easy path but really i'm just sort of trying over and over um let's see what do i think of the ion engines which made flight a couple years back um i don't know as much about ion engines but if you send me some information i'd be happy to talk with you about it um are these the ones that came out of mit um that are uh they they i think this is the concept that it's a um uh um essentially a no moving air concept if that's what you guys are talking about i saw the video too and it's like absolutely insane um it looks like it's relatively small but you know obviously there's there should be tons of money going into that space next comment it could be cool to use a catapult agree 100 catapults or ramps or other things i think have a big opportunity um it's just that's a lot of infrastructure on the ground um but no i love that concept as well um yeah so that's yeah that's exactly uh that's the concept um you were talking about how does an engine compare to engines used for smaller planes like that were used for firefighting is it adaptable to that purpose in fact it is actually um the airplane that we're that we're working on this um 100 passenger airplane called the bae-146 so i'll go back to it it's actually used in the united states as a firefighting aircraft so it is adaptable for that purpose um i think that's the last question so thanks everybody next up we have max from charge robotics uh hi everybody uh first i just want to say thanks to paige for setting up this event um my name is max justice uh co-founder and cto of charge robotics we were in the y combinator summer 2021 batch and charge robotics uh builds robots that build large-scale solar farms when i talk about large-scale solar farms i'm talking about like what you see in the background of this slide here so these are pretty huge sites uh they're often hundreds or thousands of acres large um generating hundreds of megawatts to sometimes gigawatts of power um so a couple quick things to know just about the solar industry in the us right now about four percent of our power in the u.s comes from solar and by 2050 it's going to be about half so there is a tremendous amount of solar that needs to get built in the next few years the problem is that labor is actually the key bottleneck preventing solar adoption right now so if you think about it it kind of makes sense like these sites are built often out in the middle of like very rural areas and getting hundreds of people out there for months or you know sometimes years at a time is just really challenging um and so you know as charge robotics like i don't really know how to source 300 people to get them out to a solar site for a year but i absolutely know how to ship a couple of shipping containers full of robotic equipment out there uh to build the site uh so that's kind of our thesis we think that robots are the right solution to solving this labor shortage um so if we're talking about deploying robots to build solar farms i think it's important to kind of understand the sorts of tasks that these robots are going to be doing and so i want to talk about how solar is actually built today there's kind of three main mechanical steps that go into basically every solar farm that gets built first is pile driving so you send out a crew and they hammer these large metal i-beams into the ground in a huge grid this covers the whole site then you send out another crew and they bolt tens of thousands of these large metal rails between the i-beams and those are actually what support the solar modules then you send out another crew and they bolt the hundreds of thousands of solar modules onto that racking structure uh so those three steps are common to again basically every site that gets built today um and i think one thing just to note here that's uh kind of funny is that basically everything on a solar site is really heavy uh so like a single solar module um like one of those rectangles weighs like 50 or 60 pounds um so as a single person like you really don't want to have to carry one very far and so what they do on these sites is called material staging so they send out crews with forklifts and they basically move pallets of materials kind of like close to where they need to go um and the idea is that you know if i need to pick up a solar module it's maybe only 10 feet from where it needs to end up um and so what this made us realize is that kind of no matter how we're automating the solar industry a key primitive that we're gonna end up needing is this like stuff mover this robot that can move things from point a to point b um on the solar site and so that's actually what we built uh towards the end of last year uh beginning of this year um is a giant robotic forklift and that's kind of what i want to talk to you guys about today um one second i think i just realized that uh i didn't have it in video clip sharing mode so it might be a little choppy all right i'm just going to unshare and be sure really quickly all right that should be coming through a little smoother now um so yeah this is how we built that robot our robotic 25 000 pound forklift so the vehicle of choice for this application uh turns out to be this thing called the telehandler it's basically a big forklift it has these massive tires um and the kind of relevant thing to know about these is that they're already used on solar sites uh today these are super common vehicles they navigate crazy terrain um and the construction workers on these sites kind of know how to how to operate with these uh already and if you're gonna automate one of these vehicles uh there's a whole bunch of different systems that you have to control from software um so you have the fork angle um as well as the boom extension angle you need to be able to move those just so that you can pick up pallets there's also steering throttle and brake as well as gear shifting because you need to be able to go from forward to reverse this is kind of like the bare minimum set of stuff that you have to control from software to be able to build this vehicle uh the first system that i want to talk about as the hydraulic system in the vehicle so there were two systems that we needed to control that were on the hydraulic circuit here um that's the steering and the brake so for the steering um this is kind of the sort of complicated looking hydraulic circuit for this hearing system in the top left here we ended up deciding just in the interest of time to basically bypass that entirely and 3d print a custom bracket to bolt to the steering column um so this actually ended up working uh great like we ended up 3d printing a bunch of different pieces and then just buying an off-the-shelf motor and motor controller and gearbox to control the steering so this is kind of what we ended up with this is actually what we shipped uh to our first pilot deployment uh the other hydraulic system was the brake uh so similar to the steering uh we ended up mechanically actuating this so we had a steel cable going from the brake pedal uh to a linear actuator sitting underneath the vehicle um and what is sort of nice about this design is that if i'm a person sitting in the cab of the vehicle i can jam on the brake and this cable will just go slack and it'll still function like a normal brake pedal and so this was actually a design philosophy that we decided to use for all the systems in the vehicle that we could at least so for example if you move the joystick as a person in the cab that manual input will actually override any automated control of the vehicle so this is kind of a philosophy to automating vehicles that we that we tried to use everywhere the next systems that we automated that i wanted to talk about today um sorry to interrupt i think there's a i don't know if it's a zoom window or something but it's blocking part of your slide uh is it on the right hand side that guy yeah you're right on it now oh okay yeah weird that's the thing with all the faces in it i'll just minimize that uh that should be better so yeah so next i'll talk about the electronic systems so uh that's the joystick the throttle and the gear shifter so the the first step in getting these systems working was to do uh was to reverse engineer this thing called the can bus this is a a protocol that's common to basically every vehicle that you've ever been in uh it's used to send data from system to system inside the vehicle and so if you want to take over control of some system inside the vehicle you can figure out what can messages it's sending and then send those messages for yourself so the the trick then becomes how do you figure out what the relevant can message is um and so what you can do is basically take all the can messages and graph them and then if you move the relevant input or change some variable and you see for example a line on this graph like shoot up then you know that it's very likely you found the the relevant message and you can start sending that message for yourself for the signals that weren't on the can bus we built this custom cable that sort of just kind of went in between the the main computer inside the cab and the rest of the vehicle and then we could just splice into signals directly and so when you tie all that work together uh you end up uh with a vehicle that you can control completely from software so um this was uh pretty shortly after we got the vehicle uh do not try this at home uh this was uh when we got the boom working on the canvas so we we quickly kind of whipped together this interface that i had on my phone um and then uh yeah i was able to you know take the telehandler for a ride uh through remote control and actually when we were in y combinator um a demo that we we put on was we sent that webpage to one of our batchmates who was in mexico and she was able to control the telehandler from another country which i thought was was kind of funny and there you can see kind of when we got the joystick working we had it ripped out and everything's running off my laptop there so this is this is what the early days of charge robotics look like so yeah then we wrote uh kind of a full autonomy stack and got this thing deployed onto an actual solar site in iowa back in march um so i'll skip through this video just because it's a little bit long um but we dock with uh an actual palette of solar modules uh we do some path planning we you can see the vehicle uh following a path here and it's localizing off of some cameras that are mounted to the vehicle we drive to the final location and we put it down so yeah this was back in march and with that deployment behind us uh we started moving on to our next major project which is actually um building this portable robotic factory uh let's see if i can advance yeah so uh portable robotic factory um basically there's a bunch of solar hardware that needs to get assembled on site and so we're building uh this factory that fits in the form factor of a shipping container uh that we send out to the site and it produces those assemblies so these are massive assemblies like i mentioned everything on the solar site is heavy uh these are 36 foot long uh panels they weigh uh several hundred pounds um and uh yeah it's basically like a car factory like you'd see you know like an automated tesla factory or something but made portable such that we can ship it to a solar site so here's one of the arms that we got in the mail a couple weeks ago um so with that in mind if this is the sort of work that sounds exciting to you we're currently hiring for mechanical engineers uh so i'd love if you could uh reach out uh if this is the sort of thing you want to be working on but uh thanks very much thanks max we have some questions for you in the chat um so joshua's asking does the one elevation or two terrain surface especially uh irregularities or slopes limit your deployments got it um so yeah for the most part these sites are quite flat uh just sort of by design it adds a lot of cost to the site uh if they have to do a lot of breeding um so like if the land's not flat enough they actually send out construction equipment to flatten the land so it's it's very well specced how flat these sites are in general um and for the most part we are focused on the biggest flattest sites um what type of control theory are you using pid baby pid all day every day that's uh that's what we use to get this prototype working uh as we kind of advance our technology um we're almost certainly gonna be using some some more advanced stuff but uh for the purpose of that prototype it was all pid uh and then uh it was pure pursuit was the the path following algorithm because we had a ackerman steering vehicle um so cool how much time in labor discharge saves a typical solar project site oh sorry uh how much time in labor does charge save a typical solar project site also curious who your first customers would be and why thanks good luck yeah so um uh it turns out that labor is something like 30 of the project costs and of that uh mechanical installation is about half of that so uh what's kind of crazy is that there's this labor shortage is big enough right now that we don't really need to charge less than human contractors charge for people to be really interested in our product um so for example we signed some lois with some of the largest solar construction companies in the country for about 31 million dollars and those contracts were actually priced at the same price of human labor uh so people are just desperate for more installation labor periods so we don't actually need to charge less than people um how many fewer people are needed out of deployment site by using a robotic forklift some of the videos seem to show a few workers watching the forklift yeah i was one of those people in that video that was uh this was very much like a prototype deployment uh this thing is not uh ready to you know it's not a product yet um our our complete system uh will require dramatically fewer people than than conventional labor today so a single one of our systems can do the work of something like uh several dozen people i i hesitate to give an actual number but our models uh have it as something i think it's like between 70 and 100 people um and that's for a complete system so that's like six of the the robots that you saw uh how are you controlling the forklift exact positioning uh yeah we're going to be using rtk gps uh so we weren't for that demo but all these sites have an rtk gps base station on them so that's what we'll be using to aid our localization how long does the forklift last per charge uh how long does it take to charge fully uh so fun fact they burned thousands of gallons of diesel per week on solar sites we did the math to make sure that these sites offset themselves relatively quickly but every vehicle that you see on these sites is diesel-powered including the one that we automated uh what is the most labor-intensive part of the entire project uh so you hear varying opinions on this uh but i would say the most popular opinion and the one that i share is that it's the module installation step uh that takes a lot of work um it's just those things are really heavy and you have like you know hundreds of thousands of them so that's i'd say the most labor intensive part um if there is that much of a shortage can't you charge more uh potentially it's a great point um uh very very possibly yeah and also there's things that you can do with robotic installation that uh it's easier for robots than for people so you know one thing that we're excited about is we can produce a certificate that shows that literally every bolt on the site was torqued to within the proper specifications which like you know person just can't really do very easily are you considering making an electric model um right now we're mostly not focused on like building construction equipment we're focused on uh using off-the-shelf stuff wherever we can i think it would be very cool if we could use off-the-shelf uh electric construction equipment but we have no plans to build that in the immediate future um and then i think there's one last question i've seen some projects that are also trying to automate the module installation with robots are you thinking about something like this in the future yes so um when i alluded to the robotic factory that we're building towards the end of my presentation that is the step that will be doing the module installation so the robot that i showed you in that video was really a prototype that did one thing well which was move materials around our goal is to do complete mechanical installation of the site so that includes eventually doing pile driving installing all the racking structure installing all the modules so that's the the vision of the company cool i think that was it um thank you guys very much uh and again if you're interested in working on this uh feel free to shoot me an email at max charge robotics.com or just go to charge robotics.com we have the careers page but uh thanks again and next up we have oliver oliver from impossible mining hello everybody i'm super excited to be here i'm oliver i'm the ceo and co-founder of impossible mining and we are building underwater robot vehicles which collect battery metals from the seabed and we're doing it in a way that really doesn't harm the the ecosystem that lives down on the seabed we're actually a b corp and so that's really much very much in our dna so if we talk a little bit about the problem i mean we want everyone to drive an ev you know we want to move away from fossil fuels and gas and and the good news is there's a lot of growth coming um but the down side is that all of this needs a lot more critical minerals battery metals in fact an ev needs something like six times the amount of metal of a traditional uh gas vehicle and that's really driven by the battery and so we've got a need for all of this material whilst we also want to have good esg we don't want to hurt the planet in the process of the transition so the fundamental problem with the supply chain is the fact that we don't have enough of this material the esg characteristics are pretty poor and the material that does exist in the ground tends to be controlled by china a lot of places in indonesia and africa are under the influence of china so here in the west we really need to solve this problem so our approach is to really go after what are called polymetallic nodules i'm actually going to hold one up on the camera here so this is a rock that forms over millions of years on the seabed and it's super rich in battery metals it actually is the world's biggest resource of nickel and cobalt it also has copper and manganese and there's estimated to be something like a hundred trillion dollars worth of these battery metals just lying on the seabed on the floor so we don't have to blast or cut we just have to pick them up now the challenge in picking these up is how do you do it and our competitors are basically building dredging technology this is a short clip from uh their approach these are massive machines they get they get lowered to the seabed floor and they generate all of these sediment plumes these clouds of dust effectively that that really destroy wildlife and they indiscriminately remove everything by basically squirting water into the sediment and then sucking it up over this long riser tube we don't like that approach so what we're doing is we're building fully autonomous robots and here's a little animation of of what we're building so these robots will be launched from a traditional um shipping container vessel they're fully autonomous they have a battery pack they have a built-in buoyancy engine allows them to go up and down and we use a parallel fleet you can see others returning once they get to the seabed they don't actually touch the seabed they use the buoyancy engine to maintain mutual buoyancy and then they use cameras and ai to selectively pick up the rocks avoiding any that contain life this could be sponges or corals or other forms of life and we actually leave behind a certain percent to maintain the habitat once the payload is full the battery pack adjusts the buoyancy engine to make the vehicle float to the surface where it's recovered now the payload will be emptied the battery pack will be swapped and any maintenance is performed and now the vehicle can be redeployed on on the next mission um and so you know we're basically building the team in canada to build these robots and we're just in the process of testing our first proof of concept we were a yc winter 22 company um and so we announced uh just a few weeks ago that we had closed over 10 million dollars in in funding so we're quite well funded at this seed stage and now we have to build these proof of concepts and and so we have four uh roles that are currently open um in collingwood so collingwood is a a town north of toronto actually on the georgian bay and we've just rented a very large 10 000 foot square facility and this is where we will be building these robots and and so if anybody uh is in the area and is interested please spread the word i would love to have you come and join us and and help us deliver this vision of making it easy and less environmentally damaged for everyone to drive an ev okay thanks i will attempt to answer any questions let me see let me scroll back um okay dimension size of these nodules uh yeah i'm holding one up they are about two inches diameter uh they vary a little bit but they're relatively small um they form over millions of years there's like huge numbers of them uh what's the relative density against the water um they they have they are they have some some weight so they're just lying you know they're rocks they lie on the seabed uh not attached but they're there will they control the food we rent um we have designed our robots so that they will work with traditional shipping containers and that's a big part of lowering the cost of collection and so we need minor modifications to a traditional shipping container vessel and we also use that vessel to not only launch and recover the vehicles to charge them but also to transport the payload the actual modules uh to port where they'll be processed uh in to get the metals out um uh how deep is the machine able to go so uh unfortunately these nodules these rocks they only form in areas of water that have been that for millions of years typically three to five millions of years and so that means they have to be deep so the typical depths are about five thousand to six thousand meters so you know three and a half to four and a bit miles deep very very deep are you using rgb cameras are hyperspectral we're using rgb at that depth there is no light and so we provide our own illumination we're using visible light and potentially infrared and just using traditional images uh how are you treating the biologics what will be on the surface um not 100 sure about this i mean there are lots of studies that show there are corals there are sponges and there's also other forms of fauna that lay eggs and so our ai will detect these and avoid picking up those nodules we will also choose to leave a certain percent behind for working with a team of marine scientists to kind of co-design this collection vehicle how environment economically viable versus others uh rare earths yeah we think it's really economic we want to be about a third of the cost of the dredging but if you take a brand new mine on land there are real issues with that first of all in the us it takes eight to twelve years to permit mainly because nobody wants a mine in their backyard and you often have to displace people often indigenous people and so that goes through the courts so we think the permitting will be a lot quicker secondly we have a very high grade resource this nodule has nickel cobalt copper and manganese at much higher grades than we find on land all the high high-grade metals on land have already been mined also on land they're typically very remote so you have to build a lot of infrastructure you have to build a train line or a highway to get there and on land you don't typically find four medals in one so all of these things will come out to be much less costly uh who owns the rights to the minerals great question there are two jurisdictions if it's within the exclusive economic zone of a country i.e 200 nautical miles off its coast it belongs to the country if it's outside of that it's in areas beyond national jurisdiction or the high seas it's regulated by a united nations body called the international seabed authority or the isa and they were established in the 1990s and they have issued something like 32 expiration permits uh are these on international waters uh yeah okay so yeah if two jurisdictions you're in international waters it's regulated by the isa or you're in the jurisdiction of a country like the cook islands that has established their seabed minerals authority that is issuing permits and regulating can these rocks be treated in existing facilities to extract the minerals or you need new facilities great question um you need some modification of the traditional refining but actually we also have a team that is trying to do a really innovative way to do this using naturally occurring breathing metal breathing bacteria so we have a team in la that is attempting to uh to do that why are you not using sonar um we actually do have sonar on the vehicle and that's mainly for when it is being deployed to make sure that it doesn't hard impact the seabed it's for maintaining neutral buoyancy but specifically we feel that rgb camera works better for the vision system and picking up and the fact that we control our own uh lights uh means that it's relatively easy uh how long are you out to see how much material do you harvest per hole we will do about three million metric tons in a year that will generate about two billion in revenue we have a cycle time of about two weeks so every two weeks the shippers are coming and a new crew is going on station uh won't you cry extra metallurgical isolation yeah we talked about that we have something called bioextraction that we're working on to do that why collingwood um incredible engineering talent the university of waterloo is is very close by and that's where our cto went and also access to the georgian bay uh environmental purpose of these rocks and are they part of an ecosystem uh yes um life has evolved uh to use them as i mentioned there there is life that uses them to lay eggs it's the only hard substrate and so it's really critical in our approach that we don't remove all of them we leave a certain percent behind so that life can exist do you intend lbs or other spectral density analysis um we don't need to choose which rock to pick up the percentage of the metal in each rock doesn't vary from one rock to the next they're all pretty much the same so the distinction to pick up the rock or not is based on whether any life is on it or we want to leave it behind good on you for knowing your numbers are far away from building the prototype um we built for yc at the start of this year um we built the arm in the test tank and we now have the shallow water proof of concept in the water uh we are hoping to be able to demonstrate that in the fourth quarter of this year um okay why seven percent i don't know what that refers to but uh anyway i should probably stop there and um hand over you know please feel free to to reach out to me um my email is you can reach me at oliver at impossiblemining.com in this next portion of the event we will have two quick pitches to hear about two other climate companies we'll start with inside muji meats i am inza i'm ceo and co-founder of mujimeets as you probably know meat is one of the biggest drivers of climate change but fortunately nowadays we have meat alternatives so you probably all heard of companies such as impossible and beyond but you might also have heard that on top of that that grown meat is a big emerging trend the entire meat alternative industry has one big problem though which is they can't produce good whole cuts so if you go to your local supermarket and you look at your real meat section you see like steaks fillets chicken breasts whatever but if you look at meat alternatives you will find only ground meat and maybe some sausages and patties muji meat is a habit spin-off that develops a scalable 3d printing process to produce whole cuts at mass production level and just to give you a sense of how cool the technology we're working on is we do have a corresponding nature publication that completely blew up and it broke the record for most number of readers a nature paper ever had in the first month after publication and yeah we are a growing team we hire a large variety of backgrounds from electrical engineers to buyer engineers to food scientists so if you have any of these profiles or are just generally interested in our mission um i'm happy to get in touch with you does anyone have one question for india can you please describe what the printer is like okay yeah um so there's two main differentiators that are relevant for us so for once you probably know 3d printers most of them have only one nozzle per printing hat and we print with more than 250 nozzles at print per printing hat which sounds very easy but there's a very complicated pressure regulation system behind that the other main differentiator is that we can do the material switch within each nozzle up to 50 times per seconds and which is much faster than if you all only have one material per printing hat and always need to relocate that and it also enables much more precise structures and textures if that makes sense um and next up we have josh hey everybody oh yeah great to be here thanks for allowing me to present and i'm josh santos the co-founder and ceo of noya and neue converts existing cooling towers into carbon vacuums if you have never seen a cooling tower before they look kind of like this they for our purposes at least are basically just big boxes with huge fans that move lots of air we take advantage of this moving stream of air sitting on top of a facility that has already been constructed to capture carbon dioxide directly out of the atmosphere we do that with a machine that looks kind of like this our machine consists of a few key components that we are developing entirely in-house we're developing something we're calling the contactor where air plus our carbon capture material contact each other and come together that material gobbles the co2 up as it's passing through our equipment on its way into the cooling tower the second thing we develop is a way to move the material from the contactor beyond to where it needs to go our material is a solid and so we're basically using some fancy conveyor belts think um conveyor sushi but for climate the last piece of equipment we're developing is something called a co2 regenerator it's called that because it regenerates the co2 that we capture into a pure stream it also regenerates the material that we are using so that we can use it again to gobble up more co2 i would be a bad ceo if i told you that this is exactly what it's going to look like it's not it's the vision but we are designing to this and we just uh finished our first build and we're hiring lots of folks we got different kinds of engineers like chemical mechanical electrical manufacturing controls and uh we're hiring some materials scientists as well um we're hiring the electrical engineer actively and the rest are coming later on this year so if you're interested in cooling towers or uh carbon capture let's talk you can see my email there and that's probably my 60 seconds does the load change during use i'm not sure exactly what load uh you're probably referring to the cooling load or the electrical load required to cool and then where are you storing the solid end product i know i said one question but all good so the the cooling tower with our equipment retrofitted is designed to be able to perform up to 95 or more of its peak cooling capacity we're able to do that because of the specific type of material that we're using that essentially provides both a low pressure drop across the material and also a high surface area as air is flowing through it we actually store co2 in a gaseous form excuse me on the liquid form it's regenerated as a gas we then compress into liquid and we store that in a big tank in the service area of the buildings or industrial sites that we are retrofitting foreign [Music] you
