Tahini Raving Weirdo asked:


I’m planning to build a catamaran from two surfboards, attach a DC pump motor, put a seat on it and a wind turbine (500W) and make this thing my commuter boat. It needs to cover 8 miles in under an hour and back, and I hope to recharge it over night using the wind turbine only (the thing will be moored in Otago Harbour, southern New Zealand, and I’m planning to swim out to it in the mornings using a wetsuit).
How many batteries do you reckon I need, how big an engine do I need to get up to about 10 knots, and how many wind turbines are necessary to recharge this thing over night?

As you can see, I’m a determined fool.

KZ asked:


i was wondering if i could take one of those cheap solar panals that you can power you car battery with, and somehow hook it up to a microwave, or coffee maker or something like that?

Is there any other easier way to do this.

The whole goal is to not use electricity.
