Spoiler..........they are not going to fly the Aircraft in this video.
The joy stick in the plane is a PC video game joystick. lol I have the same one. "ThrustMaster Top Gun Afterburner II"
Thanks. You saved my time
Thanks
Awww.... whats the point then?
trawing for VCs?
fatboy19831 BIG OOF
taking range anxiety to a whole new level
Hence the parachute.
at least you can glide quite effectively in an airplane after your engine shuts off. A boeing 737 can glide for 100 miles with it's engines completely shut off!
Depending on altitude of course
+Re these racing planes drop like a brick apparently.
Comforting to plane ahead when you are going to be using a parachute.
Damn batteries, WHY ARE YOU HOLDING US BACK?!!
hahaha
We have dozens of better battery designs, the problem is no one is making them yet, however the Chinese are working towards getting some of these idea's going. At least they are prepared to take risks and invest in new technology we need to power the future.
The most exciting development was the salt treating the electrodes in dry lithium batteries as it doesen't cost very much to improve batteries that are quite easy to make, but wether the West will manufacture them is debatable... again the West lately has been lagging behind in battery tech etc. it's almost as if it's being suppressed by large corporations who's interest is in fossil fuels..
bruh, lithium-air
Technology is just generally pretty shit. There have been big advances in improving life cycle of Li On, in fact it could come out tomorrow at this point I think, lots of companies have massively increased the life of Lithium cells.
Actually getting higher density is fucking difficult. You can get higher density pretty easily in a non rechargeable cell, or a cell that can be recharged a few times, but you have dentritic formation and all sorts of other horrible stuff to worry about.
Extended Li On, Lithium Air and Sodium Ion are the three I'm most interested in.
Li On that lasts longer is nice in devices like EVs where they are charged and discharged a lot.
Lithium Air is insanely light and has a very good theoretical density but the best designs at the moment require pure oxygen for cycling and also charge/discharge very slowly AND have dendritic formation which means potentially "boom boom", an issue Li On had in the 1980s.
Sodium Ion is close to commercialisation if I understand correctly, with an energy density similar to Lithium Ion at its inception, perhaps close to Lithium Iron Phosphate as it stands today, but it may be very, very cheap. So if the technology gets developed to the level that Lithium Ion has been for density, then it could mean identical energy density for way, way lower costs because Sodium is so abundant. And we can already make 300+ mile cars on Lithium Ion, it's just expensive.
As for aircraft? I don't know how feasible long flights are in a plane carrying batteries. I guess the bigger the wings, the more weight it can take, but of course airlines want the most passengers possible and you're going to need an insane charging infrastructure to charge big airliners. I have a feeling aircraft will stay hydrorcarbon for a long time, BUT, imagine it just being aircraft spewing fumes while everything on the ground is electric. That will really, really help the issue.
Whoever patents the next generation battery with very dense power storage capable of taking a high current for fast charging but relatively cheap manufacturing costs, stands to make a fuck tonne of money.
Never thought I'd enjoy this, but I've had my eyes opened.
you should...or rather BBC should - consider giving you airtime on TV - your videos are insanely interessting - and you've got that kind of "Clarkson'isme" (sry if you dont like him, but its meant as a positive) that makes it fun to watch too...
there wouldn't be enough content for a weekly show, even here in RUclips there is a few hiccups of 2 or 3 weeks without a significant video
It takes months for the BBC to make top gear! They only do about 6 episodes per year.
I don't think they even want to work with BBC.
Please don't put Clarkson in the same list as Many People who actually contribute to the development of our Technology.
We don't need another sabotage by Clarkson and his team. They love the oil too much to be unbiased.
well Scrapheap was on Discovery Channel, so that might be an avenue,
btw please bring back scrapheap challenge!!!
Small projects like this deserve medals, taking the tech further and being brave enough to do it. Old fashioned men in a shed mentality of we can do it. Very British it has to be said. It's guy like that these that won the war for us. 👍
Small scale innovates and then we can scale it up, indeed we need to encourage small innovators, surely the larger manufacturers are moving far too slow.
Yup, and it's the cocks the read Politics & Philosophy at Oxford who will make sure it never becomes an industry...
It doesn't actually. At least the Siemens Extra 330 electric plane uses a new motor design. This is just pretty much off the shelf stuff. It's an experiment into whether there is still a sucker born every minute ,and Rolls Royce has confirmed it.
You mean American men that won the war for you.
I agree with you completely.
FDR was by no means a good man.
As a RC pilot I'm not surprised at all. The instant power you can get is absolutely nuts.
People are launching huge +10kg gliders to several hundreds of metres within seconds. (We are talking ~100A at 50V or thereabouts) Or if you want to see something really terrifying then search youtube for F5D hotliners. (edit: fixed typo)
Daamn
That's actually F5D Hotliners
N221BP absolutely correct. I must have hit the wrong key on the mobile keyboard.
Things dont always scale up or down the way we think they will though...power to weight and battery performance drops once you start getting bigger and heavier. It'll happen eventually, we just need the next battery technology, something that makes lipos look like NiCD.
Three hour duration, 13,000 ft altitude and 100 km radius of operation is not unheard of for electric UAV's. Look up "Gemini V-2" for a good example here on RUclips; this craft is designed for stable load carrying and not speed or efficiency. This fellow makes and sells his own battery packs based on how Tesla do it. All of the equipment to home build and fly such an aircraft can be obtained by anybody.
When the power goes up on the motors, it sounds so evil and powerful
I've just modified the design of my 'light' 4-seater. Thanks Robert for bringing this astonishing bit of kit to my attention.
Best video I have seen for a long time. Not into planes that much but after watching this I feel I could be! More videos with beautiful demonstrations like this in the world please! Excellent work Fully Charged!
Great episode. I'm a model aircraft builder and flyer and electric in the last few years it's as completely revolutionised our hobby. We know have models we could only dream off due to costs. It's also bringing in people to the hobby because the cost and ease of electric flight. We very rarely now get a beginner flying with the old 2 stroke engines. Just look at the rise of the drones. That's only possible due to the advancement in batteries and brushless motors. The only issue with contra rotating props is noise. The Russians Tu95 or the Bear has its know, the ones Putin keeps probing our airspace with , is one of the noises aircraft in the sky especially at take off and landing.
Tu95 also has its props running at supersonic tip speeds which when you have 8 props must be incredibly noisy.
This might well be my all-time favorite episode!
"Hi. I would like to tank 1 trillion Joule in twenty-five minutes."
"Why?"
"That's my turn-around time."
I learn so much from this show. Keep up the good work.
This is probably the video I have enjoyed most on Fully charged - so nice to see an interview with four really talented engineers who are also very good at explaining concepts in such easy to understand terms.
- The national grid one was also very enjoyable, for the same reason.
Really good episode Robert.
I've been flying Electric powered model aircraft for years now using 3 phase brushless motors and Lithium Polymer Batteries. This combination has revolutionised the radio controlled model aircraft scene and has helped with the development of all modern electric vehicles.
The model motors produce huge torque and high power and some models can be as large as 50% of the real full size aircraft. Many modelers prefer this method of propulsion over Petrol or Nitro/Diesel because of the reliability and adaptability with the benefits of clean, quiet flight.
I loved this, great topic and everyone seem genuinely excited and enthusiastic about the project. Beautifully shot and edited.
"everyone seem genuinely excited and enthusiastic about the project"
Why? It pains me to see people gush over rubbish, but to quote the title of a W.C.Fields movie "There's a Sucker Born every Minute".
The aircraft has flown. It reached it's very modest design goals, of flying a little over 300 mph for about ten minutes. in the 1950's airliners were in regular transatlantic service that cruised as fast as that. This aircraft has no potential to be nothing but pointless. By shaving away anything that isn't essential and sacrificing any flight endurance at all, they have managed to reach speeds ICE aircraft attained in the early 1930's, but even those aircraft had much better flight endurance. A 90 year-long giant step backwards.
Another great episode and this time with my second interest FLIGHT!
300 horse power!? For that little thingy!? Amazing, kickass, awesome, sweet, FANTASTIC!!
Thanks robert, one of the coolest videos yet!
300 miles per hour, not horsepower
So could potentially fly at lot longer at lower speeds. Say half hour at 100mph.
Dear me, that was one of the best videos I've seen on you tube. It's just so exciting to see stuff like this moving forward. Take note the rest of the world, thanks so much Robert for all you are doing :-)
Found this a seriously enjoyable watch. Thanks
Excellent video Sir. Robert!
Really excellent video, thank you very much!
Nice to see other aspects of electric technology being applied to old fashioned ideas.
Keep the videos coming
Thanks
Loved this episode, more of such innovations please!
It's very impressive that they've integrated a ballistic parachute into the airframe. They still aren't widely used, but every small plane should have one in my opinion.
No reason not to.. just cost, but saving lives is worth it!
It has cost benefits too, you get to recover the airframe.
It does cost a lot and has to be designed from the start. My argument against it would be that aircraft are already very safe, and by adding this large price increase you will reduce the market. A 30 year old Cessna will cost you $40,000
idk what your talking about, all my planes in kerbal space program use it.
lolz ballistic frame chutes statistically dont save lives. Good airmanship does.
With electric aircraft, we get to relive the early 20th century. I can't wait until we have a Lindberg moment when someone flies an electric airplane across the Atlantic!
Michael Harmon. I feel the same for RC aircraft. Too bad some of it is about weaponizing them. Silly people and war push the technology as well as hold us back on using the full potential of it. If we actually focused on it there is no reason why we could not have an integrated flight path for humans in flight via pilotless systems. Step into a pod, choose destination, and step out. depending on distance it flies in most efficient form.
Joshua Weaver It has to do with the heart of man Sir Weaver. Oh what tangled webs they weave but Yeshua will judge and not deceive.
An electric airplane has been flown across the Atlantic. But it took a long, long time ...
Solar Impulse finished the first round-the-world electric solar flight in history! Achieving the impossible. Building the first airplane to fly day and night without a single drop of fuel.
Michael Harmon
Lindberg was not the first to fly the Atlantic. ;)
Wow what lovely professionally done video - thank you fullchargedshow for putting so much excellence into it and thank you patreon supporters for supporting such an excellent channel.
Absolutely amazing I'm just so glad that this is coming in near future.And as someone else said on hear ,thank you for making this video it was very pleasant surprise.
Can't wait to see it fly!
That was so interesting, cheers
one of my favorite videos ! thank you very much !
Really enjoyed the video, thank you so much !
that was impressive.
I hope you do continue to follow this
@Mr Brightside Brits tend to dawdle and make things overly complicated, loving red tape that strangles progress. They will eventually make an airplane once they are afraid of their government subsidies running out.
Fly the plane at max altitude and dive down, it will charge itself by using its turbine as a windmill.
I didnt think I'd make it to the end when I clicked the video, but I made it and it was worth every minute. A very interesting and well done video from you once again
That is one amazing concept. I hope every factor comes to their favor.
This is great! I love when new advances in technology comes about
Sure, but this thing doesn't actually advance any technology. They bought the lithium cells off the shelf. The motors, propellors, battery protection and speed controls are probably hand made, but they are derived from quite conventional existing technology.
Robert this episode has been a real treat, thank you so much for making it.
Everything about that plane is sleek and beautiful- I can't wait to see it fly.
It isn't going to. Who knows if they ever will build a flyable aircraft? No news of that development even four and a half years later.
@@herbertshallcross9775
Their web sites say they are doing work with Rolls Royce.
@@johnburns4017 Apparently the aircraft has flown, slower and with much less range than comparable iCE aircraft. The speeds it has attained were reached by iCE aircraft in the 1930's. This is not progress. it is a giant step backwards.
Rolls Royce has an enormous engineering department that will spend zero time working on this project. The cooperative relationship is almost certainly limited to Rolls Royce's advertising department. Rolls Royce's products have a major carbon problem, injecting enormous amounts of CO2 into the sensitive upper atmosphere. This is Rolls Royce tying to distract greenies who think electric aircraft will ever be more than a gimmick from their core products.
@@herbertshallcross9775
It is the efficiency not speed that matters. Electric planes offer that. Existing planes are being converted in Canada. Fully Charged did at vid on it - like today.
@@johnburns4017 Electric airplanes are not more efficient than their ICE equivalents. The overall power package weighs significantly more even when you subtract a great deal of endurance. There is no offsetting benefit. That is why they are both slower and have less range. Yes, Harbour Air in Canada is converting excellent all-purpose aircraft to much less capable electric aircraft, for no rational reason. Must be government or foundation money in it.
Absolutely FANTASTIC !!! Both Show and Material
Another excellent show! This programme always leaves me feeling excited and optimistic about the future.
Being a bit on the picky side, and being trained by the RAF in the trade of propulsion fitter (the highest technical training available) Please note the difference between contra-rotation (one ening and a gearbox) and counter-rotation (two engines working independently of one another. Hence the a/c has counter-rotating propellers. Also, the 'mixture' on light a/c is manual whereas on larger a/c the mixture is altered automatically by the fuelling system (Either the carburettor, or the fuel-injection system). Just small points but aid accuracy. Sorry to bore you.
Not boring, especially the difference between contra-rotation and counter-rotation.
I will inform the team. Thanks.
My pleasure. It's just that I do not like to appear a smartarse.
You are correct, though the larger planes tend to have variable pitch propellers too, so you still end up with several levers per engine. That's why I prefer jets or electric. One lever per engine/motor. :P
An excellent point. Fewer levers = less complication and lower weight.
Piston engines can (and should) be single lever controlled with a FADEC system.
robert that was more than awesome .... :)
I usually don't get impressed easily but what this man is doing is indeed impressive because he demonstates ingenuity and substance. He does not seem like he just saw an idea somewhere else and claimed it his own. He's definitely gonna make far up in the sky (sorry I had to)
Good show. So glad I watched it.
Suggestion....Put the props in a aerodynamic duct. Eliminating the wing tip vortex (s) from the prop tips will increase efficiency about 27%. I design, build, and fly Radio Controlled aircraft. My love of flying started back in 1959. In '76 picked up my first 5 channel radio, been flying R/C ever since. I am 65 now. Currently working with Blended Lifting Bodies, Delta Wings. Very low drag.
That's what I was thinking... You could easily mount a duct on the test rig. Also, how are they measuring combined thrust with 2 separate thrust stands? Does the base have its own load cell?.. Or is it as simple as combining the 2 thrust stand numbers?
I would LOVE to see more of that company in the future !
Can you do a cover up of their maiden flight ?
c0rsaire92 Yes Please!
Enjoyed that thoroughly, thanks!
Bravo! What a fantastic episode.
Kinda made my heart sing!
Can't wait to see that flying! :-)
I think a key point made was that propeller aircraft technology became "parked" for a few decades because of jet engine development. Electric motor and battery technology has the potential take propeller or fan technology to the next step.
So much potential it's revolutionary.
Propellers don't really work at the speeds that airliners or fighter jets fly at. For those you'd have to use a ducted fan if you want to go electric. Actually modern airliners already have ducted fans, it's just that a jet engine drives the fan, which produces most of the thrust, while the jet engine exhaust provides only a fraction of the thrust. So if you had a powerful enough electric motor you could power the fan with that instead.
Skräcken Russia has large prop bombers that can fly at least 550mph (some clocked faster) the same speed as the average air liner, they are large prop craft which carry very heavy loads at some very high altitudes, there is no reason why you wouldn't use them in a hybrid system, it just wouldn't be super fast, but nor is the average air liner.
Indeed so, but it's at the extreme end of what props can do, and it's also one of the loudest airplanes ever made. The americans tried to make a supersonic propeller fighter too, but it simply didn't work. And that one was so loud it actually made the ground crew sick and some even became unconscious.
Skräcken Electric engines are quieter even with a prop, we also have quieter prob designs nowadays, you would be using generators to power the electric engines (in a hybrid system), there would be a significant drop in noise compared to old soviet bombers... I think also that it would be possible to use solar panels to get some power back also, lots of possibilities there.
Apart from fact that I love Fully Charged show I absolutely adore the english pronunciation of the last gentleman in this episode (from 12:44). Wonderful english! I am not a native speaker, but I love the way he talks. Greetings from Czech Republic and keep up the good work! ;)
Jus saw this well made and exciting video! Thank you!
Wow that's quite breath taking isn't it!? All that POWER!
It really sounds like the future of aeronautics is going to be an exciting one @_@
MichaelKingsfordGray I know that -_-
But what was interesting was how much power they got out of that dual propeller setup. You know? The thing that was shown?
+Kenneth Newbery search up Tu-95 on RUclips. it's a Russian propeller powered bomber that's counter rotating too
What's interesting about a technology that was abandoned in the 1950's
There is only one production airplane that I know off that uses that setup today, the Tu-95 Bear and the AN-22, and both used tubo-props and there hasn't been a new version of those in 50 years.
1940s even, contra rotating propellers were even trialled on spitfires
spawnof200, oh yeah, the Griffon powered Spits I think.
I think I just fell in love with the simplicity of that experiment at the end :'D
Another great video, thanks Robert
Great video and excellent class! Thank you so much!!!
"This is 50 kg, an equivalent ICE is 150-200 kg. So it's an order of magnitude difference."
This coming from a bloke who says he's an engineer annoyed me somewhat.
truelazerlight Was that lad called, “Saint John”? 🤔
y
Good one Bobby:)! Electric planes are just as interesting as electric cars (though we can't so easily buy them:)
Can't wait for new Reg Worf!
Well people have been making electric ultra light craft at home for some time.
But air planes in general are not a cheap hobby, not to mention the immense amount of paperwork before anyone lets you fly at all.
An absolutely fantastic video. Great small documentary and fascinating. More of this please and I will become a patron. Brilliant!
Thanks that was so interesting, nice to see other industries taking advantage of electric improvements!
Loved that. Eventually, electric power will completely transform the designs of planes, as it has already demonstrated the capacity to do for land vehicles (though sadly there are few original ideas that have made it beyond concept designs). A tangential suggestion to this episode: have a look at drone racing.
Unless we managed to make a better battery ion think anything would *l e a n m e a n g a s o l i ne*
Fantastic, looking forward to seeing the results of their work in a few years!
It's time maybe?
I have been an avid RC aviation nut for over 30 years now...The last 10+ years have been exclusively electric and for all of the reasons listed in this video. When I started back in the the days the planes were all nitro powered, heavy, noisy and messy. It was the only way that we could fly. But then the first brushless motors hit the market and everything changed. The thrust to weight ratios went through the roof and the ease of operation was even better than before. I now have models that are capable of 180mph while only consuming about 380watts of power. That was unheard of in the past. Electric power has come so far with batteries being the only thing holding us back. Thankfully they are catching up now! Fully electric cars are a reality now with the planes not too far behind! Take a look at my channel to see what the RC variants are capable of now...
Absolutely stunning. I dont have any background in electric motors but am a pilot and aviation enthusiast. If you ever have a position for someone to sweep the floors, I'd do it just to be around something so revolutionary. Truely remarkable...
This was brilliant
Stonking!
15:30 When you notice the model motors start driving the full size prop on the prototype. Insanity!
That's because electric motors are 2 strokes, they are an electromagnetic form of 2 stroke with high power and few parts. Also lightning bolts are 2 stroke because they fire down a streamer and up a return stroke sometimes it can go the other way, but its one of the most powerful and energetic 2 strokes known!
Exciting stuff,cant wait to see the full scale fly!
Outstanding vid. and esp. engineering.! We don't need no stinkin' carb heat! I'm a retired M.E. - that twin engine on the same centerline is awesome at so many levels!
That's great! Thank you.
Visit them again when they get close to flying! More electric planes please!
Red Bull seems very well suited to electric planes, I had the same thought watching the Reno Air Races, they only fly for a few minutes and the batteries you could fit into a plane should be enough.
the Production quality of this channel is amazing, I hope more and more people come and watch!
Really beautiful aircraft concept. Simple and polished
Hmm, April 2019 and it still hasn't flown...
Now they're off playing with putting electric motors in a Nemesis NXT?
What was wrong with finishing the Red Bull project?
Aaaargh! You'll never fire your machine gun through those props!
Well, not twice, anyway.
MrStuart21. Maybe pulses of a laser. We would be wonderful advanced society if we mount them in the propeller itself. make them spin and cut a whole on the other plane or spiral cut a plane like a zucchini. And serve it toasted as well so we are not cavemen serving things raw.
Even more advanced societies might not go straight to think of shooting planes down, having better things to do with their time. I know, I know, I like to play with 1911s myself. Still ...
risa bear. for sure. def read into what I meant by advanced. what human could define advanced anyway. there are already lasers on planes. Just no slap chop like lasers or free shipping wait there's more.
MrStuart21 fewer blades would make that easier, actually. This has two blades per cycle, so a full 180° window to fire bullets through.
sure you could...the firing mech is driven by prop position..simple,
just not necessary. guns don't belong in this story. elect tech does.
Stunning little gem. Well done all involved.I can't wait to see this thing in the air.
Bet you're still waiting.
Fascinating and eye-opening. Looking forward to huge changes in aviation in the coming years, thanks for this glimpse into the future!
This technology is a very important step toward sustainable air transportation. Thank you very much Robert.
No it's not! This thing does nothing to advance battery chemistry, electric motor design, aerodynamics or pretty much anything else. There are battery powered light sport aircraft, and they all share one feature. Anything they do has been done better long ago by internal combustion powered aircraft. There are probably more four to six seat aircraft that can fly better than 100 mph for hundreds of miles, and with an instrument rated pilot do the same in all but the most severe weather than any other class of aircraft, but so far there isn't a single electric aircraft in that category because electric power systems do not produce enough kilowatt hours, and no battery chemistry that is threatening to go into production in the next decade can .
High power is easy, just look at the model flying community, they've been doing just that for years. The hard part is a long range electric plane.
An overunity motor generator could be used like john Searl magnetic motor generator or a Witts generator.
absolutely brilliant stuff. can't wait to buy one
omg it's one of the most beautiful airplanes I have ever seen
another big middle finger in the making to the oil industry?
Imagine villages in like Vietnam where it's takes days to travel to by car, imagine if they could have planes like this charged by solar panels, how accessible would it be for them to get stuff that they want?
Driving a car and a plane are two very different things. One takes a few lessons, the other months. One you can teach yourself, the other you would die in a ball of fire if you tried :)
MomentousGaming So? what's the difference? It's not like people would fly a plane which they don't know how. The aviation industry could switch to electric. Which is still a middle finger to the oil industry.
I replied to Taha who postulated giving electric aircraft to small Vietnamese villages for transport instead of cars. It wasn't a response to the parent comment.
+MomentousGaming accessibility teaches, and they already use airplanes, but normal ones
amazing, great video. this stuff is gold.
Wow the production quality of this channel has jumped massively. Great work everyone. Keep it up.
damm impressive :-0
Seriously, never heard of contra-rotating propellers?
Exceptionally well done! Clearly articulate; far beyond just proof of concept.
I genuinely have goose bumps for the success of this company. Thanks for an amazing video report. I am feeling quite air-sick after this 17+ minute electro-fest!
What is success? They managed to get somebody to sponsor them, and they may actually get the thing to set a new electric record, but there is no market for what they are selling. What use is a fast extremely twitchy aircraft that can only stay in the air for about twenty minutes and probably costs 3 million bucks?
Contrary to popular belief noise isn't an area where electric planes will make any difference. All of the noise you hear from most common airplanes is the propeller, the engines actually don't rev that high and aren't particularly powerful or loud.
Computer. er, no. try listening to an engine on a test stand with no prop.
Try listening to a prop with no engine, it sounds the same.
Computer you could easily knock of 10dB (note: log scale) without the motor, however, this would be with a conventional propeller on an electric motor.
because of the movement of air around both props, compared to conventional piston-prop engine, there may not be much difference in volume, although sound pitch might be higher without the sound of a piston engine.
Most piston aircraft engines have no muffler and at high power settings are louder than a leaf blower
Contrary to Computer's statement electric aircraft IS quieter. I'm working daily near electric aircraft (check Pipistrel Alpha Electro) and also piston engine aircraft and the difference is huge (Rotax 912 vs electric motor). In the air and on the ground.
I WANT this airplane. NOW!
I hope it flies as good as it looks... gorgeous!
Well done Robert , these fully charged shows are brilliant , well produced very interesting deserving of a prim-time tv slot . i have flown electric powered model planes for over 30years and the advent of brushless motors and lithium batteries over the past 15 years had finally made the planes perform on par with the combustion motors , im sure this aircraft developed by this forward thinking inovative team will have very , very impressive performance with many advantages.
Good to see haters of this video are in the vast minority.
I think most people want to see us trying new things and EV's are part of this, it is only a certain amount that is dependent on the fossil fuel industry that is trying to hold it back, one of those ways being negativity towards EV's. But Fossil fuels is the tech of yesterday, we cannot use it forever, EV's you can!
Ken Heslip The word is stark, not vast
Because it's so much better to gawp and say "Gee Whiz!" than to actually understand.
How about the Sora-e?
What a great episode Robert, really informative. Wish Electroflight all the best with the project
Very nice. So that's land and air now on board with the electric transport revolution, just the sea to go now :-)
No expensive engine overhowl , negligible maintenance, no pollution, runs cheep cos its electric .....wow.
saw something that said the fuel weight of an airliner that could fly from NY to Europe with reserve, if translated to battery power wpuld power the same airliner for about 20 min.
I just stumbled upon this video, nice to see Robert still doing cool stuff!
Stacking the propellers like that, reminds me of the compressor blades of a jet engine. And counter rotating them, to cancel the issues of 1 propeller. This is brilliant. I really like this.
pitchin my idea here: fusion reaktor airplane!
Yeah, sure. The idea has some merit. You'd just have to work out a few trivial engineering problems. Like finding a material for the shielding that weighed less than 8 tons, and which took up less volume than the size of the entire plane. And then there would be the irritating little conundrum of how to contain the radiation in the event of a plane crash. Otherwise, what could go wrong?
Zero point energy or aetheric energy from the vacuum, Tesla did this and so has t henry moray and many other, look at john searls rotary generator and Joseph papp's pulsed plasma 2 stroke inert gas engine. The electric motor is an electromagnetic 2 stroke that has a lot of power and few parts!
