Thanks again for all your hard work it’s so wonderful to see the transition to electric aviation . Maybe someday we will all have our own Flying vehicles after all
I hope so too!
For people like Me , I Don't know what we do without you... The way you explain everything is so simple and everyone can understand and I really like the Researches done by You and Your Team... Thanks alots for startin this channel... GOD bless You , Your Team and all Your Families with lots of love and happiness and with good health and wealth...
Thank you
@@ElectricAviation ...You are welcome...
It's about time. I've been thinking about this for years.
Great video. A couple of comments if you don't mind.
I have yet to see any "slightly more expensive" thin film cells. All the relatively high efficiency stuff (GaAs-based) is VERY expensive and, like GaAs-based "space" cells, likely always will be.
You show multiple clips/images of the ISS (International Space Station) solar cells. The ones with the 4 holes in them. These were the original cells and they are single junction Silicon. I worked with a gentleman that originally worked with the company that made them and he was kind enough to give me "rejects" from various stages of production.
A lot of great info. Thank you
Excellent presentation. Thank you!
Glad you enjoyed it!
Тамаша! 👍
Nice job ❤❤❤
The Lightyear 0 electric car looks promising. Designed very different from traditional cars, to reach maximum efficiency on every part. The same philosophy as electric planes.
Have you seen Aptera Luna?
@@michahalczuk9071 Interesting. Getting it to production is the challenge with all these concepts.
@@headcrab4090 Aptera Luna is in production and they already sold out first 1000 pcs.
Top model will be available later though.
They have modular design, so they don't go through extreme production hells like others.
Edit 1k pcs not 100.
Man, thank you for this very interesting video)
I am fascinated by the potential for box-wing designs to create an aircraft that has a large amount of surface area in the wings for solar/gliding, but also more favorable handling characteristics and frame stiffness than typical gliders.
Love your channel, thoroughly good stuff.
Even multi junction solar cells produce 1.3kwh per sq m which if a 737 wing and fuselage were covered, would produce around 60-80kw per hour. Not there just yet but there's certainly an argument to increase the use of the technology. Solar cells cost have plummeted and multi junction increase in production will only reduce cost.
Well presented.I got a lot from it!
You will never bring down the cells price until you start a bigger market.... aircraft is it's next bigger market...
Perovskites are said to enable cheap multi-junction cells by 2030, 30% at first though.
I hope light flexible cells become efficient in the future, so they can cover the whole body in solar cells.
There's also a company that produces 50% transparent glass that has half the efficiency of normal cells, so 10%, so the canopy could produce power too.
Typically these kinds of cells are used in conjunction with a parabolic mirrored concentrate the sunlight this reduces the cost and such cells have shown the ability to handle more than 900 sons this means that if concentrated sunlight could be used the mass of the solar cells could be greatly reduced one way to do this would be to cover the upper surface of the wing in something called a holographic film these were developed in the 1980s and never found a real market but they have the ability to focus light sunlight it from many angles to one specific point they could basically follow the sun during the day wings with a clear with surface and these holographic films could focus the sunlight onto cells mounted on the lower wing if that lower wing were made of aluminum it could help you connect is a heat sink in this way cost could be kept down as well as mass
Not one punctuation mark. Remarkable. Also, you're wrong about "Typically these kinds of cells are used in conjunction with a parabolic mirrored concentrate the sunlight". The great majority of multi-junction GaAs-based cells are used in "1 sun" (no concentration) applications.
Yeah I was trying out the microphone - sorry about that. I suppose I should not have said “typically “ but they have been shown to handle over 900 Suns.
@@stevemickler452 Apology accepted!
One point with solar powered flight I find interesting: available power increases with altitude. At 20km you are already 90% above the atmosphere, which means much more energy from the sun impacts you directly without scattering. That said the question is how to launch to 20km? Maybe drop batteries? Maybe beam powered? The launch system might be the most overlooked part of the equation.
It's only a matter of time. Step by step they will get closer to their goals for EV aircraft.
Eviation is working on a battery electric airplane for commercial use, short distances. Perhaps this solar cells could help it?
Did not realise the max theoretical efficiency is as high as 90% 😲.
Solar powered airships have been around for over a decade. Solarships is testing a vehicle that can lift a a 20' container with 9000lbs cargo off a soccer field fly 200km at 75mph and land on a soccer field using solar power and solar charged batteries.
Bring back the bi-plane.
Nice 👍🏼
Thanks for the visit
The Delta wing has the largest surface area to drag ratio, though is has a higher angle of attack at low speed, but that would be the ideal topology?
light is not all cells have to absorb.
As they (and this is crazy) get less efficient with heat, you need to absorb the heat too, wich is a double win since you gain new energy (heat) and the photoelectric cells work better when cooled (or put to a certain temperature).
Isn't there a way to absorb the heat and turn it into electricity? I have seen wood burning stoves - for camping - that turn heat into electricity so it can charge an electronic device.
So all these are efficiency per area not weight, weight is important in aviation but I do not know any good source on this. Secondly, there more expensive so less good but more might be better ti make up. Thirdly, some solar cells can be structural too reducing weight penalty. In other words, it’s much more complicated than presented
There was a literally coating just before Covid broke out that you could paint on a surface and create a solar cell just a coating. Also there’s a new technology which princess solar cell on glass surfaces very thin it appears to tint the window slightly and it cost is the same as having your windows UV tinted the same machines used with a few modifications Both technologies look very promising
@@gregkelmis2435 "Solar paint" or "printed solar" are real oversimplifications. While it's true that very thin layers of "photo active" materials can be painted/coated/printed onto various materials, there's still quite a bit of "segmenting" and "wiring" that needs to be done in order to build voltage to useful levels.
What up with tech people? Just "sky-scrape" the arrangement of cells and concentrate the sun's rays like with a fresnel lens system and viola! Efficiency will double and triple for the solar cells. Build them like city blocks and sine the light in between by all means, the physics is already available.
Are multi-junction solar cells so much more efficient because they are in "direct" sunlight outside the atmosphere, whereas the other solar cells, even thought they may be in "direct" sunlight, that sunlight is being diffused by the atmosphere thus decreasing it's intensity?
true, the atmosphere filters out the spectrum so MJT would perform at lesser power output and maybe efficiency too
I would like to contact the creator of this website
With the impressive content I hear , It needs to be done with top quality speach! I could help . Jim
I hired a professional voice over artist and unfortunately bulk of the subscribers voted it down. They prefer my own voice, which baffles me too
Do you have a Merch store? I like your plane emblem, would look nice on a shirt.
Working on it!
@@ElectricAviation can ya make sure to have XXT size im 6`6 and hate tees that show my belly button. Thx : )
It doesn't address in the video the weight per sq mt of these solar cells. Do we know anything more just to see how I can modify the fabric on my wings, also according to you the price is 10 folds the one of commercial solar panels, so if I need to cover 12 sq mt of wings, that equals to about 12 panels producing about (5 kw/h x 30% = 6,5 Kw/h) and the cost is $12000 but it would provide only 10% of the power needed for a 65 Kw propulsion system. In reality when cruising the aircraft only needs 20Kw so we could practically extend the flight 20 minutes. I think I need to change aircraft. I will try with a motor glider.
"Solar impulse was slower than a car on a highway." Not during rush hour it wasn't.
or just Lead Selenide, PbSe at 0.27eV band gap, ie, infra red capable solar cells
just one junction
use the flywheel wing as the solar surface
circle wing acts like a delta wing
just add a tail and a main rotor
dont look at the sun, its too bright for you
oh wow I haven't seen synergy in a while dang
Have you heard anything new from Synergy Aircraft?
@@PC-vq5ud i havent in a long time, i know john used to have a facebook group where he posted updates but i dont use facebook anymore, i know they got that deltahawk engine and last i heard they were just working on the composite airframe, but its been years now since i heard anything, whats it been like 12 years since the green flight challenge? land sakes
You'll be shocked to learn about the new perovskite solar cells that have an average 70% efficiency.
I certainly would be shocked. Can you provide title of paper/website/whatever that shows this "average 70% efficient" perovskite solar cell?
I highly doubt that, some day anyway..
5% efficiency in real world
Nope. 18 to 23%
*Solar radiation will never have the power density to power electric vehicles, especially not aircraft. At most, they could slowly trickle-charge electric batteries over a long period of time.*
It really depends upon the size of the panels. Yes the small backpack panels are good enough to trickle charge batteries but we are talking here about solar cells with peak power of 3 kW and above. Flights have already been demonstrated as mentioned in the video
The Solar Impulse plane has already circled the globe on solar power. Solar Impulse 2 flew for over 76 hours non-stop on solar power. Airbus solar plane flew for 26 days straight. Solar airships could fly indefinitely.
Yes. But zero use able payload.
Solar radiation can provide enough energy if used to recharge batteries or synthesize a fuel on the ground separately, before the flight.
@@taylorwestmore4664 Solar Impulse had a longer wingspan than a 747, yet it could only carry 2 people and fly at an average speed of 48 mph. A 747 is well more than 10 times faster and can carry more than 200 times the number of people. The chasm between the capabilities of those two aircraft might as well be the distance between galaxies in the universe.
Wow, where is solarImpulse now? Oh, it broke up and crashed.
It did what it was meant to do. It proved solar circumnavigation was possible.
@@ElectricAviation Yeah well, it would have been honest to point out that it ripped apart in a gust of wind. It's like reporting Wright bros first flight without saying it crashed after 20m.
@@tuberroot1112 I think had we focused on Wright brothers crash, we would have never progressed. Both Wright Flyer and Solar Impulse were pioneering feats.
@@ElectricAviation There's a difference between "focusing on" and failing to comment on and pretending it did not happen. Chemical energy stored in fossil fuels is way more adapted for powered flight than chemical energy stored massively heavy batteries. Only the hysteria over CO2 can unbalance the logic enough to make this seem like a positive outcome.
Hard time understanding speaker in English, rough accent 😢
One of the reasons I never got solar is because it sucks so much. If they wanted to push us all to renewable they would put out the best inventions they have behind closed doors. But then again you don't want to buy a VHS player then a DVD, then a blue ray of digital downloading is already out for the public
I believe Solar is a good investment and one that truly empowers a person. Yes there are places around the world that might not be that sunny, but in most places it pays itself back at most in 7 years. It has a life of 25 years
I have had a "grid-tie" solar array since 2012 and it "paid for itself" about 3 years ago and is still working flawlessly. In short, it doesn't "suck". Do you live under a rock by chance?
