Surely the problem is not the engine weight but the battery weight.

Saving weight anywhere on an airplane is a win. The new engine claims to have more power output than other engines of the same weight.

Yeah exactly, but given the numbers, it doesn't seem to outperform Tesla's engines? Perhaps they're also taking in to account the power usage as battery weight is more significant in planes... idk would love if it someone could help me understand it better though.

You could do with mimnimum battery ans send energy to the plane with laser maybe ?

Good joke!
