Why not? any electric motor can be used as a generator can it not?

I don't think my question is understood... But thanks for your time everyone... I think the only way is to get two of the same motors, hook them up and give it a go...

Vertical axis wind turbine boat... I've seen mechanical versions no electrical

If you are turning a generator by hand that is directly wired to a electrical motor will it transfer the electrical energy produced by the generator to a electric motor more or less efficiently then with a pure mechanical system? assuming that the input energy is located away from the output...

sailboats do not require more then say 15hp because they can only reach a certain speed because of there design. there is a motor called a torqeedo its an electric 9.9hp outboard and it was used in its testing to power a 40 foot sail boat at normal speeds

thank you

you can't compare an electric motor with a gas motor.. so i should find a 250hp electric motor??... right thanks anyways

How many Hp would an electric motor need to reliably power a half ton 4x4 truck? Thanks

What would be the wattage ratting for a gas/diesel generator to power an electric motor with these specs. 72-144VDC 190A Continuous 43.7HP Continuous Thanks

The electric motor is using battery bank #1 while #2 is being charged by the vert turbine/solar/gas-gen. What you are asking is i think called a series hybrid setup where the turbine is directly sending power to the engine, so up wind it should theoretically be neutral because there's more wind...

Thanks for your interest. I have built a few things with the idea of "Alternative'' propulsion and i simply like to go against the grain. I'm not very experienced with electronics thus why I am here. I guess my basic question is - Would a 120v / 240v - 5000 watt Vertical wind turbine be able to...

Yes i have, thank you.

Hello, Im new to the forum, i joined to ask a question about a boat I've been obsessing about for awhile. My idea is an aluminum sail boat (27-40') that has its mast removed and replaced with say a 3-4kw vertical wind generator (350lb) i know that's a bit heavy but I am sure the wind forces are...
