Are Electric Planes Possible?

Basically , we cannot get big full size airliners running on electricity , not for a few years yet!

I understand what you are saying but I don't think you are factoring in the fact that electric motors are significantly more efficient then Ice. so although the battery is heavier, the motors require less power for similar performance not to mention electric powered motors are significantly smaller and lighter, cheaper and simpler then jet engines. regardless I know the amount of energy the battery can hold is still less then the fossil fuel but it does make it seem more realistic when putting it into perspective.

The answe is still NO, 5 years later, all "promising projects" is now cancelled, including one of NASA's-
You cant base your projects on future improvements of batterys and motors, if they fail, your project fails too.

Nikola Tesla's Wardenclyffe Towers, powers electric cars and airplanes.

Hydrogen?

Why does the cross-sectional Area that the plane sweeps out include an entire circle instead of only the half below the wings? This is the area of air the wings displaces downwards, so why the full circle, and how do you determine the area of air affected by this displacement?

Well, in any case, it's easy to see why batteries have limited viability in airplanes atm. But that's why the airplane industry should be focusing on R and D to create hydrocarbons for fuel electrically, with captured CO2. If they can manage to improve the efficiency of this process they can create fuel... and this would allow countries around the world to manufacture petrol for cars, meaning they don't need to invest in infrastructure for electric cars or require their populations to buy them (a problem in poor countries where people rely on old vehicles).

Depending on how long the electrical wire is, yes.

If solid state batteries become a thing maybe? Toyota's been talking a lot of shit about them but we haven't actually seen anyting mass-produced yet. Hydrogen seems like a genuinely good option for airplanes, though it still has the problem of not coming from Green sources. Very little hydrogen is produced without carbon emissions.

imagine charging the batteries as well lol. Planes are always in the sky and not on the ground.

The only challenge according to me is electric motor can’t produce that much power or thrust or you can say force to push the flight like engine will do it with its powerful nozzle like rocket

Another thing worth pointing out is that the amount/weight of the kerosene decreases as it is being used while a battery pack weighs the same wether it's at 100% or 5 %

Would it be possible for you to do a short update these figures with new battery systems that have been developed in the last 4 years since you produce this video

What are all these equations? It's not even rocket science but I'm lost

Anything is possible but electric planes will never ever be reliable and efficient enough without fossil fuel plane takes off it weighs less as it burns fuel as we know some planes have to dump fuel if they have an emergency after takeoff so we’ll have to have an electric plane it’s very very light and won’t be able to carry much it rains will not be good electric planes will be in novelty

100kg for passengers and luggage? is there a child piloting?

Why don’t they put turbines on the plane? so as the plane flys, the wind will spin the turbines and charge the second battery, while the plane uses the first one.

278WH/KG was cutting edge tech. It's crazy to think 5 years later and CATL has plans to release a 500WH battery specifically targeting the commercial aviation market.

I am 13 and your vidios are the only way I can understand these complex equations keep up the good work! Thank you!

why electric generators ( once started with electric power can run by their own generated electricity universal shaft and motor running by produced electric ) are not used inside planes instead of heavy weight battery

There is no more tec than electricity.talking about efficient safety.still need invent tge best way

Need to install DC battery plant in the planes !

Saying power increases 8 fold because of that '2' when mass is doubled is incorrect... That 2 is as good as a constant (such as g²)
The mass is multiplied by that 2 before doubling as well.
Doubling mass only increases power required 4 fold.
Surprised to see someone in your shoes make this rather silly mistake

This video is to confusing.... Have you ever heard about layman terms... Stupssssssse

Waw as an accountant I really don't understand these equation..hahahaha

Malicious EMP noises.

Please explain why you use the term fossil fuel.

We drill for oil at 38000 feet
The deepest any fossil has been discovered is at 16000 feet.
Petroleum is not from organic matter.

No.

Possible? Yes.
Practical? Not likely for most commercial applications.

here’s a short answer
probably yea

So batteries are just to heavy to power planes. Got it.

Possible.. YES
Practical... Not yet.

After reading the title of this video, "Are Electric Planes Possible?" The one thing I could think of to answer that question is yes. If the extension cord is long enough!!!!

I'm a Tesla fan, no I don't own one, can't afford one, but I can't see an electric plane flying from Sydney to LA .

Commenting from the future here, not only are they possible but in the year 2023 we have them. Electric planes are a thing now and many airline companies are buying them for their short haul flights.

Yup, batteries won't be powering commercial airliners, long-range semi-trucks, or locomotives any time soon. It'll be hydrogen instead.

Why are you wasting time with batteries, the mere fact that a Tesla has 1200 lb of batteries, that is six 200 lb people, that itself eliminates batteries for the likes of cars. As of right now, the only realistic replacement for fossil fuel is Hydrogen, seeing as though time is of the essence regarding climate change, we need to stop beating around the bush and get real about H2.

NO!

I hate flying. Look how many people are stuck on the ground during this great xmas storm 2022.
The trains however, rolled thru that storm no problem at all. How big & heavy will a battery pack
for an airliner need to be? Remember they will have to have 2 for redundancy. How big will e
motors need to be to lift an airliner full of people off the ground? I'm betting HUGE. My dream
come true is that it will not be possible to do & that will re invigorate passenger rail. Maybe then,
we will get high speed rail like all the other civilized counties of the world have. We would ditch
the current diesel loco dragging a bunch of deadweight passenger cars for no loco at all. With all
passenger cars be self e propelled like Bay Area Rapid Transit trains are in the San Francisco Bay
Area. Just think of the time we would save not having to go thru airport security. And think how
enjoyable a train ride would be where we could actually do some sightseeing. Well, at 300 or 500
mph maybe not. Hope - hope - hope...

!

Or in a short u could explain that an electric car is 3X the weight of an ICE car. Now imagine that kind of weight comparison that would be in any airliner and the destruction to a runway dealing with that kinda weight jump! Not to mention the extra time on the tarmac waiting to charge! Simple math

I do not think electric planes are going to work; because you are putting on passengers and other items like bags of mail and packages; making the plane very heavy

I think a hybrid version would be safer if electrical engine fails there's gas to keep afloat.

The answer is nuclear-electric. A small nuclear power plant providing power directly to the electric engines. Crash site cleanup has unique challenges, though, so don't crash it!

Currently, no battery technology even comes close to the energy density of aviation fuels per unit mass.

Because carbon free aviation is still just a scam

It doesn’t produce any exhausts, but it took lots of emissions generated by coal or gas to charge its battery. There is nothing even close to the energy density of a gallon of AvGas. And as you fly an aircraft powered by petrol, over time it’s performance gets better because it has burned off the weight of X amount of gallons of AvGas and can now fly higher, to drop its fuel consumption and extend its range. Or catch a better tailwind and increase its groundspeed. With a battery powered aircraft, the performance you took off with is what you get until you land. The altitude you initially climbed to is all you’re going to get. The TAS (true airspeed) you took off with is all you’re going to get for the duration of the flight. Battery’s are performance limiting and utterly inefficient for powering airplanes.

Nope. Physics Energy density says no

You didn't even mention that an electric propeller plane can't make an equal thrust to a commercial jet. Simply put, there are no electric planes that can travel 500 mph.
