I have been researching a bit more about my wind generator project, and to my disappointment the project is so unsure when it comes cost/benefit and technology that I will skip it for now. The main problem is that water heating demands so much power and many AirX owners have not been able to get the desired amps from the generator. This means that I feel the project is too risky since I would have to invest nearly 2.000 euro in generator, controllers, wire, batteries, heater, cone etc. etc. 2.000 euro is a lot of wood - about 3 years usage for us or similar to nearly 5 years electricity.

Instead I will focus on insulation, more about this later.
