An airplane needs over 100,000 hp/75,500 kilowatts of power with a mass of 100 tons to be able to fly properly.
Which battery on the market can deliver this performance permanently?

Loading...Can I expect my suitcase a day later or should I have it picked up a few days earlier?
Hello, I have a mild version of von Willebrand syndrome and would like to be a flight attendant, but I can't find anything online about whether that makes me unfit to fly. Can someone who knows something about this help me? Thank you. LG
Hello, I'm hoping someone knows what to do if you miss a flight. We wanted to fly to Dubai and unfortunately missed the plane because there were problems with our suitcases and we had too much luggage, which meant there were delays at the counter. Unfortunately, that was a shame. We wanted to fly the…
I'd like to travel to southern Italy, so I'd like to use Interrail. Preferably alone. Who's been there and what tips do you have?
Hello, I haven't flown in nine years and haven't seen my friends, relatives, or family. I'll be flying with my family soon. Am I allowed to bring a small suitcase full of masks, creams, perfume, serum, etc. as a gift, to the airport?
We have a 40-volt battery-powered snow blower from Gartenmeister that now constantly shuts off after four seconds, even without a load. The battery indicates full. What could be the cause?
Yes, it’s unrealistic. Electric trucks are already unrealistic.
The ironic is also, the battery itself weighs additional weight, with combustible drives, the aircraft becomes even lighter in flight, as it consumes fuel.
So light and powerful, rechargeable batteries are not yet available. But they could still be developed. It’s not excluded. Maybe based on XeO3.
In addition, an aircraft can use photovoltaics once it is above the clouds.
Power is less the problem than energy density. It fails. Modern LiPo batteries can achieve considerable performance levels.
None.
Therefore, according to the current state of the art, this is simply not feasible.
I think it’s easy to build a plane that can lift and fly with electricity.
The problem is to build an aircraft that can leave longer distances with electricity and operate economically.
This is not possible (still). The larger the plane, the larger the battery should be. What makes the plane heavier. And this in turn needs a larger battery. So a vicious circle;-)
You know that you don’t have to fly with battery, you could also use hydrogen and fuel cells for power generation – and that would not be so dissimilar to today’s kerosene.
Well, kerosene is liquid. Hydrogen is a very volatile gas.
Hydrogen can also be liquefied, otherwise it is precisely used in techniques to bind the metal or the like, and kerosene is liquid, but also with a very high proportion of volatile substances.
A leak is also dangerous for kerosene.
Easy and heavy and please have no leak otherwise will be fun for the flight passengers
Extreme cooling is necessary for liquefaction.
A carrier medium is necessary for a chemical bond. Both are complicated and difficult.
You forget the factor of pressure… with which liquefaction goes far earlier.
Hydrogen will only be fine at -254° and keep cool
The battery would be (at least) three times as large as the aircraft…Come up with it..^^
And at least 6 times so hard
