Could you create a battery powered plane?

In summary, the conversation discusses the potential use of electrical powered planes instead of fossil fuels and the challenges that come with it, particularly with the limitations of current battery technology. Scientists are actively researching and trying to find more efficient and lighter batteries, but it is a difficult task due to the energy and power density differences between batteries and jet fuel. Despite the potential advantages of electric motors, the current state of battery technology is not enough to make up for the energy density differences.

ROLLS-ROYCE TO FLY RECORD-BREAKING ELECTRIC PLANE
"In the first quarter of 2020, Rolls-Royce will unveil ACCEL, which it says is the fastest all-electric plane ever designed."

It is a one-seat racing plane.

To break the current 3-year-old speed record of 340KPH (212MPH), they expect a speed of 480KPH, (300MPH). They state that the data acquisition rate is >20 000 points per second to optimize the actively cooled battery system.

"Look to the skies over Britain to see this plane in action."

Now THAT sounds like a bit of a project!

Cheers,
Tom

agreed. It would be fun to read about the engineering of that plane.

For comparison: Even tiny business jets fly at over 700 km/h.
