Does anyone know what companies are responsible for manufacturing the parts to build giant wind turbines on wind farms and whatnot?

How to make a DC motor into a wind generator?

I need to make a wind turbine for a science project, i have everything else sorted.

I’m using a DC motor from an old remote controlled car that used a 7.2 volt battery. Is there anything i need to do to this before it can be attached to the spinning shaft of the windmill, or can i hook up the wires to a lightbulb and let the thing spin?

is it feasable to install a wind generator on cars and transfer electricity to a storage battery?

and when people get home plug into home , use what is produced , if any excess it would go to the grid.

What kind of inverter do I need ?

I am making/designing a generator that produces electricity to power many items at one time. I need an inverter that will connect to my home grid to power my house. It is not a solar generator or a wind generator.
I need to know what kind of inverter to get. I know that a regular inverter will not connect to my home grid.
