Build your own wind turbine.

Build a small wind turbine, then build it bigger and bigger.

Put on a generator to get free electricity.

Use this blueprint for private use.

If you want, you can mount the wind-discs above each other on the same drive shaft.

You can also place multiple axes next to each other and connect them together.

I start by using a 1 meter standard 12 M threaded rod, 12 mm nuts and 12 mm ball bearings.

Common woodwork may be used in tests.

A small problem seems to be what kind of generator I'm going to use, thinking of a regular car generator. The problem is that it starts charging at a quite high speed so I have to change the gear.

Keep the weight down to just that it holds together, and learn how to maneuver the vessel.

Then it could be possible to sail with?

A kind of wind turbine boat.

You can not sail against the wind but cross like a regular sailboat.
