its so easy to stop a fan blade with fingers and keep it in place.
but i read that a human can produce 200W of power on a bike generator.

and 500w is enough for moving e-bike

also ill drop another question here.

How can you transfer more ampers to a motor???
lets say you hook up 2 1.5v aa batteries, so it forms 3v battery
batteries dont have amperage but they have amp/hour. so you can unload them as fast as you can

so how would u transfer more amps out of battery to a motor?

because if u hook it to a motor it seems like it tranfers set Wattage

sorry for english. thanks for answers
