Check out this expose' of the engineering of Rolls Royce's erectly powered speed-record breaker.
It was purpose-built to provide 40-KW for eight seconds.

Recording an eye watering 345 mph, the Accel Plane is officially the fastest electric vehicle on the planet! Before it retires to the Science Museum, Imogen and Robert wanted to meet the team from Evolito, Yasa and Electroflight to find out how they've made electric flight take off! From axial flux motors, advanced cooling and packing staggering amounts of torque - this plane is choc-a-bloc with astounding technologies that are paving the way to mainstream electric aviation.
00:00 A lot can happen in 6 years
01:19 A 345mph all electric aircraft
02:31 What's the point in breaking records?
03:05 The techy bit and a load of motors
05:24 What's next for electrified aerospace?
06:00 What about the batteries?
07:34 Drain the battery in 8 minutes
08:18 A tiny gigafactory
08:48 A whole lot of power from an impossible motor
09:48 Axial vs radial flux
11:15 All torque
12:20 What's next?
14:20 A hub of ingenuity

If it is "erectly powered", do you have to have a boner to drive it?

Something that everyone needs...

Both electric motor technology and electro-chemical battery technology
are over 200 years old.
Li battery technology is over 100 years old.
Motors reached 98% efficiency years ago so there are no possible major >improvements to batteries that can be made.
Li batteries can theoretically be improved by less than a factor of two.
Most Li research is going into faster charge times without the battery
self destructing.
