and that's it for me up next planets. i take a look at the realities, possibilities, and limitations of the technology surrounding solar cost. i'm a little outside and for me in the teams haven't been in thanks for watching. taking it for like the get ready for an exciting auburn toyota for look, surprised. hi, i'm shopping and i'm ready to dive into the hands of children. to have you as a one the front porch. clear and come to invest deposits on the spot. and unexpected side to side enjoy the

the holy grail of electron mobility. so the power is cost for you. fuel from the sky, gigabytes, worries about range and charging time. the simple but brilliant idea that let 2 companies who proceeded into bankruptcy. so know motors in germany and like in the netherlands to be seen as a lot of ways to ruin the concept. they put everything into building their own sort of costs and fail. so what's the big deal breakout about solar costs? the 1st we need to understand how they work. that's why we're here in the awesome

germany with a solar ice team that's on the bottom. so this is one of the most efficient electric vehicles in the world. yes. i mean, you can look at it right. it looks like a ping pong table basically, so it doesn't have too much in common with the normal car. this is and we'll do back back in 2017. he was one of the founding members of teams on barton, in awesome 18 to participate in solar racing competitions across the world. for example, in australia, i mean that it looks a bit like a soapbox. like, yeah, like a desktop you could say and it's, and little bit it writes like that too. so how many kilometers do you think? depends, right. depends totally on the sun, right? if you're driving without the sun, it could be around 600 kilometers. that's a rather small 6 kilowatt hour battery. but if you have a good sun direct sun like then you can drop and definitely fix it. you can just

keep going. of course, it's depending on the speed then, right? if you don't have too much sun, you have to go slower. yeah. and it has a top speed of 120 kilometers per hour and is covered in full square meters of so the cells. and it has only 3 wheels with the engine sitting directly in the wheel in the back, while the cost would be sufficient as possible. aerodynamics key. just to give you an idea how light this is when i do this, like the whole cause taking. how much does it weigh? it? it depends little bit on the battery chemistry, but somewhere around a 160 kilograms. okay. yeah, it's just fuel be made of the carbon fiber. everything is, is mills out of titanium or allow me minium car fiber. so lightweight is, is definitely a way to go because everything else is more rolling resistance. holding resistance

needs more energy. the 1st on the car wasn't even the lights on in 1955, william g called at general motors design to some mo bile about the size of your hands. in 1962, this 50 year old model baker was equipped with solar cells in 1980 research at columbia university gave the best to the ugly duckling, a tiny call with solar panels on the roof and foot. but building solar cost is a bit more complicated than just slapping solar cells onto a tiny com. the 1st big challenge is the suns angle solar cell to generate most energy when the panels of pumpkin dixie low to the sun. that's why some sort of pox even ton from out the day. but everything on the car is fixed and round. that means sosa operating in the less ideal conditions. unless you own a competition car during the mandatory stops while the racing, they can pop up there. but so you stop, pop up the hood and then you basically have the perfect thing for the sun. just

sign on the yeah, i don't see that with any normal kind of have this. the 2nd challenge is that you need to use special solar cells. these close to about 35 grams on the top. we have . busy all across the crystal and silicon cells, right? how efficient are these? so these are on the 25 percent, right? and it was 4 square meters, so it gives you roughly a peak. i'll put off a kilowatt hour. obviously the same sales that are on roof these days. for example, this one you can find on your, on groups for example. but the difference here is the encapsulation, right? this is a very efficient, a calculation that drops the light a little better. then you find the stuff on the road because the stuff in the roof and, and also commercial seem to come solar cars has to be more into price. don't scratch so fast. and because as i said, we don't want to touch them and that is not feasible. for, for commercial vehicles. but the real crux of commercial solar costs is that they

are much heavier than they raise costs. and so i can only produce so much power. that's why making them run only on solar poa is really, really hot. like every other electric vehicles, they also have batteries that can be recharged on the grid. but the solar cells are actually web. bankruptcy started for solar cost offs like so much as from germany and light, you know, from the netherlands. because manufacturing the south is quite complex. usually, panels of straight part in solar costs. they need to be carved. the electronics become more of a challenge when the, the surface is quite curved. this is less hoss slot, co found out flight. yeah. he also comes from so that's how racing. because then one sort of cell is a looking at the sun in a different way than the other side of the cell. and then you need complex, i tronics to, to still get most of the yield of solar panel. but that's not the only challenge the cells should be robust and shouldn't spend if the car crashes and integrating

them into the top part isn't easy either. so you start re clause, then what you add is a kind of a conductive back sheet. it's gold. so basically it's a printed circuit board for them, flexible, and then you pick and blaze the solar cells. on top of that, i print circuit board buying the machines, buying the materials, developing manufacturing processes. and after you did all that, you need to get your newly developed so the cop pods certified for every day streets. all of those costs a lot of money sign motorsports if needed to, to 300000000 euros. just to go into mass production, know pocket money for stop, but solar sales are only one part of the puzzle. the other one being how many kilometers you actually get out of it. and that's why it's a lot of things to consider. the size of the solar already begun means more generate to the energy location on the globe. some countries get most on then

others time of the year, of course shading dust on panel of solar panels aging which makes them less efficient and more. i know there are studies that fact it and some of the things but not old and it's mostly calculations and not real. will long term tests keep that in mind. so how many kilometers do you get out of this? well, it varies anything from 293 kilometers at the low end to $3400.00, up to 5100 kilometers per year. a problem is that all these studies assume different parameters like size off the so now, right, possible power allows foot with the shades or not just an example of how much of a difference that makes that only increasing the p v area by half the square meter you already get 2078 kilometers instead of 1444 kilometers per year. that's what so no motors and like you did,

they increase the size of the solar rate. so no, when for 6 and like you full 5 square meters, projected ranges with $34.00 or 70 columbus is per day, both promises that couldn't be kept. so no, it couldn't raise enough cash. the company is restructuring and selling off that. com and you factoring capacities like your underestimates of manufacturing costs. they plan to sell that like a 0 full 120000 bureaus, but increased it to 250000 zeros due to expensive comp pods. they filed for bankruptcy in 2023. it is a very low volume exclusive. can you go that when financial markets change and a lot of focus comes on the actual margins of the products generating? then this debt project is not the perfect fit for the market, right? so that's why we'd have to restructure. they are now trying to build a cheap, a cock cold like you to buy us. still looking for partners and investors. the us starts up at tara motors which shut down in 2011 due to lack of funds,

but came back in 2019 with new bacchus looks also great on paper 6 on right. and so what is pretty columbus has a range? 64 additional kilometers per day, costs below $40000.00 us dollars. bots. when nbc tested the prototype, our test model had some obvious flaws and it could barely make it uphill without overheating. our so i think you're the 1st person ever drivers on groups. not a good look bought the actually already. so the cost on the right. well kind office . so the cop, the young dies will not talk, for example, hybrid card with the solar car roof, which under ideal conditions will give you 3 to 4 extra kilometers per day. yeah, not that much, it's more of a nice to have design future talking to industry experts and cost suppliers, big common effectors most looking at. so levels as optional. so it's really hard to predict how many vehicles will be actually equipped with it. if we don't

fundamentally change, because the parents of solar panels impact will always be quite limited. but what happens if you blow one parameter completely out of proportion? something that is being tested right now by the truck manufacturer us scan yet in sweden, in collaboration with folks at our university. are you what's file that has been going on since september the 20? $23.00 instead of 2 square meters like most cost, the hybrid truck has 113 square meters of solar cells that charge a battery in the trailer for an estimated 5000 kilometers of edit range per year. we expect maybe somewhere around 5 to 10 percent of the energy that that can come from so not in the gym. and that's why i should say that that is also is we've done it, which is um, maybe not the best place to test this. this is eric johanson, he leads the trial and is in charge of the scientific data collection book you have seen before. it looks to be your other segment or what the expect actually. so that

is, um, what most surprising seem are they even ran the numbers for southern europe, and that could turn out twice as much energy. so there are some great use cases for solar. when vehicles are very lights and they are deployed in sunny regions. lucky and 2 units with these delivery tries that goes all the small boxes for public transport and nigeria that mainly run and so the power so the cost to manufacturers almost when's boss, we don't know how much energy we're going to get out of it at which point today you can already put a solar panel on your roof and power your electric vehicle. it's through your cost roof. is that weight that can be used otherwise, but until that has an impact, it's going to take a lot of time. the if you did like the video, please share like and subscribe to all channels. we post
