The FAA recently contacted me and requested permission to use this video in official training materials on powertrain electrification. So if you’re here from the FAA, sorry for the bad jokes.

This is one of those rare cases where I thought "I'll watch a few minutes and see how it goes" and 42 minutes later, I'm still watching. This is presented far better than most of the big TV science channels manage. Thanks

Good video. My major concern it the extreme “all or nothing” mentality when it comes to “zero emission” and “all electric” vehicles. The hybrid engines you mentioned are good examples of necessary compromise - but such a compromise is unacceptable today. Pollitics of the moment would never accept 95% or 99% electric. Case in point, todays fully electric vehicles could double their efficiency and range with a very small, very simple propane heater (to warm the batteries and passenger compartments - saving precious battery charge for propulsion).

Another day, and I've learnt something new. I had no idea Electric Planes were even a 'Thing' Jaw dropping planes actually flying around, smart people working together. I'm Amazed. Great presentation.

Yep , this vid answered all my questions that electric aircraft are coming.... but what about the ever increasing weight of the passenger.. Mmm

The amount of information in this video alone is amazing. Thanks for putting this together

Until there is a significant breakthrough in improving the power density to weight ratio it will remain a novelty. I wish them the best. They also have to figure out a way to ecologically dispose of these batteries along with eliminating the strip mining necessary to obtain the ore to build them.

There's a guy in Monticello Kentucky that is building one that is AMAZING!!! I watched the video and my jaw hit the ground when I saw what it did. I love it when average people build stuff like this and their product out does the ones from huge factories especially those that only make planes...haha. This country boy just happens to be very smart when it comes to aviation I guess. Everything about his electric plane out does every plane I saw on this video. It look bad ass also....thats what I like about it the most. It looks almost like a jet. Very sleek and looks super fast.

Accidentally stumbled upon this video. Never knew such a quality content about electric fans existed. Very informative and excellent content. Well done. Subscribed already and looking forward to more videos.

Great video. Really like the format. Also you used "comprise" correctly. That won my sub. 😂

Rather a lot of ad breaks but a really well-researched and fascinating presentation.Thank you.

Excellent informative and well produced video. Worth the watch if interested in the future possibilities of aviation and electric power. Thanks for posting.

Comprehensive and well presented coverage of electric aircraft- thank you!

I just came across this channel, and I am impressed about the thorough research you have done on this topic. Good job! I am subscribing.

Hydrogen (which makes little sense for cars) makes way, WAY more sense for most planes than battery electric.

I saw the thumbnail and thought "Eh, let's see what this is all about". 42 minutes later I'm subscribed.

I’ve almost always sat at the window, and marvel how I can jut sit there and fly.

Dude, this is the best commercial I have ever seen!

With a long enough power cord there is really no limit to how far or how long you could fly this plane. Really awesome.

Just found this video today. Great information and amazing research. Though,one thing I feel wasn't touched on was the cell life of the batteries. There was a brief mention at 39:41, but the amount of battery waste and replacement cost due to limited cell life is another big concern.

THummbs up for content and your hard work bro...highly educative and and a good combo inbetween debating within and connecting topics

The breadth, depth, and quality of the coverage in this episode is outstanding. Excellent work on a fascinating subject. Kudos to you.

Still a long way for commercial use. Two challenges 1. range 2. payload (ie battery weight impact.)

I don't fly at all, but this is a cool idea that others can use. I'm sticking to my truck personally.

When a longer video pops up on my feed, I tend to glance at the comments first. The reviews are so good that I subscribed before I even watched the video.

Outstanding production, well done. It is very encouraging to hear such good news while so many mainstream sources of info focus on hyped up shock and awe bad news.

"Due to the nature of flight and the grim reality of gravity..." Love it!

From what ive hard, seen and, read. The bent wingtips are to accommodate larger wingspans at airports without having to reengineer the terminals.

Fun fact: The tip design is more to do with aircraft standard sizes than to do with vortex management. The only thing that passively reduces the vortexes (hence reducing lift induced drag) is a large aspect ratio, which is a ratio of a wing's length and width, i.e. the longer and skinnier the wing is the less drag it produces. Hence you see gliders have very long skinny wings. So to solve the issue of lift induced drag you simply have to increase the wings length, however, there are limits to wingspans of aircraft, hanger size limitations, airport limitations and other factors, you can't make the aircraft to wide, or you'll go up into a higher aircraft class and pay more hanger fees and rents. So manufacturers come up with these wing tips, they effective increase the length of the wing within increasing the total wing span too much, however it is less efficient than just having a longer wing. Hence new planes like the 777x have folding wing tips, theg fold up when in the airport and stored, but fold them down right before take off. To get the best of both worlds. It's even stranger with private jets, more often than not customers ask for wing tips because they look good, even tho they might actually hurt fuel efficiency compared to simply a longer wing. Ik the video glossed over it, I just wanted to give extra info.

860 lbs of battery for 100 miles vs 318lbs full fuel load for 850 miles. We need a break through in battery technology before this is even remotely feasible.

Fascinating stuff! I'm sure we'll see short-mid-range viable electric aircraft soon. As for long-range, we'll need a battery-breakthrough for that.

You mention the lack of noise as a selling point. I LOVE the noise during take off in a big jet!.. I'd absolutely hate to be in a quiet tin can and not have that theme park rush. The rumble, the bellowing engines.. it all makes you really feel how hard you are punching physics in the face to fly in the first place!.

Amazing video, so much innovation information in very short time. looking forward for the next level of electric planes with faster speed and longer flight distance.

I can feel all the hard work behind making the research for this video!! Thank you for sharing 😁😁

Fascinating contribution to this discussion. As I see it, electric aviation is still constrained by several things: 1. The efficiency of propeller-based aircraft greatly decreases with altitude, which means that long-range electric aircraft cannot take advantage of low-drag high-altitude flight like mainstream jets can. Never mind that there is a hard limit to how fast any propeller aircraft can fly. Transatlantic flights in a long-haul-propeller-electric airliner would be tortuous. 2. the aircraft/payload weight ratio is still untenable for high-volume adoption, especially for longer routes. The most optimized revolutionary design from Israel that you mentioned is 60% battery and it only carries about a dozen passengers for less than a thousand miles. It doesn't help that battery mass does not decline with its consumption. 3. Hydrogen is a dangerous fuel. It's basically corrosive and difficult to contain at any temperature, especially at cryogenic temperatures necessary for high-density storage. It's costly to manufacture as well (a lot of the energy put in to electrolysis doesn't end up as hydrogen). Any leak can be deadly to your aircraft, since the threshold energy for combustion is extremely low (you could end up blowing your plane out of the sky just by a tiny hole in a tank). 4. As much as battery tech is talked up, I don't think battery energy density will increase all that much in the future. Li-ion batteries already are pretty dense, considering they are already made of lightweight materials and do not require a reactant to release their energy. (Consider that all jet fuels use oxygen to release their energy - oxygen which is not stored, but simply pulled from the atmosphere.) Safety becomes a big concern once you put too much energy in a small space, especially if there aren't natural safeguards against runaway energy release. Jet fuel requires relatively specific circumstances to combust which are easy to prevent even in the case of a tank leakage. One can't say the same for batteries. It does not surprise me that this has found appeal in markets where the high ratio of aircraft to payload and the very limited range is acceptable. I do not really see how hybrid or hydrogen aircraft will be more economically viable than jet fueled aircraft when it comes to high-payload or long-range flight. I'm honestly banking on more sustainable sources of jet fuel rather than battery technology. We're literally swimming in sources of carbon and hydrogen, and liquid hydrocarbons are ridiculously practical for storing and releasing energy. Either way, your video was well written and sourced. Thankfully not clickbaity or hyper-enthusiastic like a lot of fake science channels on this site. Kudos for that.

Fascinating video. Lots of fuel for thought. Got to admire the folks behind all the e-planes. Cool video, Jay & look forward to watching more. It's the future. 🤩👍💚

Lots of info in a fairly short Video Great Job!

Instant subscribe based on watching this incredible (now favourited) video that I shall need to watch again. Thank you!

"in anticipation of breakthrough battery technology"... oh that's the part where the magic comes in?

Yes, noise complaints were the Concorde‘s Achilles heel, but it was more the sonic booms the plane kept emitting and not so much the engines.

This is an insane amount of work for electric planes. Good work man.

39:20 "You need to get high really fast." I see what you did there.

Excellent narration and editing. Thank you for not having obnoxious, loud music.

9:00 make the wing small and optimise for high speed flight. Use an alternate propulsion system when slow. What happens when you lose all power? You have no propulsion and not enough wing to glide?

At 6:50, the problem isn't that the JET A-1 powertrain is merely 26% efficient and the equivalently powered electric motor is 90%, which is all well and good; it's when you have to push that aircraft thru the air at 700+ kph that the efficiency gap closes really quick. It's the Cd, or coefficient of drag that is the main constraint you need to overcome. It's just basic physics. Fix the Cd, and you can solve the electric aircraft problem.

Excellently produced, realky outlined the problems electric aircraft have, thank you really enjoyed this, give one alot to think about...

Colour me surprised. This video was recommended to me, and from the thumbnail I thought this was absolutely going to be clickbait. Wow it isn't, but what it is, is a fantastic documentary! Super interesting, super informative and super educational :)

The first electric plain did not have batteries on it but those were in fact transistors that transferred the voltage from the electric power cord that it was connected to. It has a 50 foot electric cord and it did not fly at 7 miles and hour but instead blew up after 2 inches off the ground.

You made a believer out of me with this most excellent video. You also made me a subscriber. Thanks!

39:05 "There's too many things to be invented still" YES! to electric future!

Great video, Pipistrel has been one of my long time favorite trend setting companies. Although i'll never be able to afford it, i've wanted to fly their planes for a long time.

No one ever said an electric plane was impossible. They said a commercially viable cargo/passenger carrier is impossible. And it is.

Concur on coverage and fidelity. Thanks!

Like many others, I watched your video and was very impressed. I subscribed immediately. Great job on your research.

For large airliners to be fully electric, it cannot defeat the law of physics. You will never see an electric airliner with a range of 3,000 miles and/or can fly over 500 MPH. Ground transportation is possible but not commercial air transportation.

This is hands down the best thumbnail I've ever seen.

These hybrid units are interesting. Especially because APU’s are already generating high electric power in some planes. The 787 has bleed-less tech meaning the APU generally starts the main engines with electric power.

There is a sequence of events that need to take place; Steam engine->steam turbine Gasoline engine->jet engine Electric motor->some sort of jet created by electricity, still waiting.......

It's not only an issue of finding enough power for the motors but also, those battery packs can handle only so many recharge cycles before they need to be replaced. Unless we have some huge advancements in motors and/or battery technology, I can't see electric planes being the norm anytime soon or at least, not anytime in my lifetime!

I loved the presentations of the newer technologies. I'm no expert but I understood the concepts and applications and can see that this was a factual documentary . I believe that this technology is about to experience new sciences that will open new doors . Nicola Tesla had the open mind that was necessary to concieve new technologies and others will follow.

Well produced. Don’t forget the accessory power necessary to de-ice leading edges and pressurize cabins.

What a beautiful design! I wished the Beechcraft Bonanza V-tail were further tested as it reduces structural failure of the more common T-tail. Otherwise, I'd like to go back to the tail on the Super Constellation L-1049. But that creates more point of failure and why I love the V-tail Bonanza. Lets do some more stress testing on the V-tail against the T-tail with large passenger aircraft. Meanwhile, not only 'yes', but 'hell yes' when it comes to flying an electric powered aircraft! Airplanes love to stay airborne, so it doesn't scare me at all. Bring it on Boeing!

consider some of the wilder possibilities this could open up. The tiny living movement also spawned liveaboard sailboats, and some of those are even going to electric drives that can generate power when under sail. It also spawned van life and all the different power options mentioned here for that too. Now imagine one of those solar electric flying wings that is also designed to be a small apartment and amphibious. There's actually so many different ways it could go, maybe have wings that can fold back so it can be driven on the highway like a pickup truck towing a camper? However you want to design it, Flying life might become the new thing. Could even have a smart cockpit that would be a traditional cockpit for backup, but a smarter auto-pilot and with things like heads up AR displays to show various air-spaces and info about them, like what channel to contact that ATC for. Doing that might even make flying safer and make getting a licence easier. And how much more efficiant will something like starlink be when you're up at crusing altitude?

I guess you'll need a sophisticated control system in the event of the loss of power from one of the wing tip motors. The assymetric thrust would cause a near instant uncontrolled spin unless the small motors on the other side ramp up immediately to resolve the imbalance.

Nasa is always at the center or in the conversation on everything flight. As a tech giant into Space flight and research, I believe they've done a great job keeping up and contributing to the cool things going on around the world.

"Ladies and gentlemen, we have an electrical fault. Nothing to worry about though: We have plenty of parachutes."

Captain: "were out of baterry ! were going down ! Start the recharge!"...24 hours later

GREAT video ! I really enjoyed this video. Thank you

Batteries remain the biggest hurdle to overcome. Even short hops are not reasonable. As a frequent business traveler, I know there are weather events that can keep a plane from landing and keep you in the air an extra hour or more. Electric planes cannot stay in the air an extra hour.

This video was very informative on the innovation of electric flight. Very impressive in my opinion. But I'm just a layman in the field while understanding the basics of the technology.

I like the idea of electric airships, because they don't require much energy for lift, just propulsion.

When the narrator actually understands the topic So that’s what that feels like

My idea is to keep the plane tethered to a power source right up until rotate which takes most of the energy. When it reaches a certain altitude the tether is disconnected.

If we had batteries that would have 100x higher energy density, we'd be set for so much technology change.

It'll be more practical once they improve the battery. They do have many experimental batteries, like one that uses diamonds. Once they're able to harness fusion, everything will take off exponentially. Who knows when that'll happen, and be reliable and safe. It's really an interesting prospect.

Absolutely brilliant,learnt so much thanks👍🏻

Great video! I study a lot on ev aviation and you hit the marks!

One giant leap backward for man, one giant leap backwards for mankind!

I love the fact that the caption "Batteries are affected by the low temperatures at" 4:49 and the next slide that dissapears immediately are not mentioned by the speaker 🤣

They're doing this with current lithium battery technology, imagine where this goes when battery tech makes the next leap and doubles its energy density! Hyped for the future of electric flight!

Excellent, subbing!!! I fly All Electric RC models. Have only flown Electric models. Brushless motors have really made a high leap in performance just like lite LIPO batteries!!! I have a multiplex Delta wing that was GPS tracked at 131 MPH about 5years ago. This technology is really coming along fast!!!😉

I await the first electric aircraft to fly 200 people across the Atlantic.

Happy to see Ordinary Earthlings taken back their planet Earth from Fossil Fuel Mafia!

Electric hybrid gliders would be a start E Taurus looks way cool go Alice.

lithium ion batteries can explode when overstrained, maybe consider something else like liquid metal (have fewer passengers). at least jetfuel burns somewhat slow and there are techniques to slow fire spreading in extraordinary circumstances. the lithium ion reactions would be much more violent

The possible making of an electric emissions free aero plane is welcome. We could use lightweight supercapacitors to try and increase the storage of electricity on an aero plane. Also , solar panels that work in low light conditions may help. Also , solar panels that gain power from radio waves as well.

Cloud cover works both ways; it increases albedo, reflecting incoming light. At the same time it traps heat. You can easily see this. Cloudy days are not as hot during the day and not as cold during the nights.

Brilliant presentation!

Certainly encouraging developments. Well done also to the narrator, for a super slick narration.

I am the one that love the engineering in planes, but I am not a window type guy. I think it is more comfortable in the isle. but I do agree with you here, planes are cool

That Rolls Royce EXCEL is one of the most beautiful aircraft ever created. Can't wait to maybe see one of those in the sky at some point in the future. If money were no object, that EXCEL would be the first thing on my list!

I feel like I'm in college, attending a class on technology.....I feel good

Excellent video, great piece of work, well researched and narrated. I enjoyed watching and have subscribed. Thanks.

The creation of the “new combustion engine” I saw the other day here on UKposts. Used as a electric generator may actually mean electric aviation is very doable. The weight of the motor vs output was literally insane vs All other current combustion engines…

As always the energy/weight ratio is the killer; we're not quite there...yet, at least. The challenge of making an electric a/c fly could be matched by the challenge of persuading people to climb aboard. Sod that, i'm a bit of a dinosaur i'm afraid. My favourite type of a/c to be aboard is one with a pair of petrol engines, and with single engine capability.

This video is absolutely put together with great info!

as a slovenian a am proud

Zero emissions from the plane but tons from the power station that made the electricity.

I stopped after 5 minutes because there was NO mention that battery efficiency craters as the temperature gets colder than 32 deg F., something that absolutely happens in high altitude flight. And if you are using the electricity to heat the batteries, you still lose efficiency from having to heat them.
