Bats can spot an insect in the dark as small as a millimetre, they are not going to be fooled by a giant windmill.
They can even tell different types of plants apart by sonar, no need to worry.

Some of you have no clue about physics, a battery and motor is 60-80% efficient and an engine is very inefficient. Using precious solar electricity to make hydrogen to burn in a very wasteful engine is just plain stupid.

Using natural gas to run a powerplant to make hydrogen to run in an engine is realy stupid. Just burn the natural gas directly in the engine.
