First of all, I have gathered all necessary parts for micro wind generator. An old VHS videotape which will be used as a membrane, two small neodymium magnets taken from refrigerator -magnet souvenirs or from PC HDD, and finally coils - (see Picture below, it is from washing machine controller motor). You need to fix the magnet(s) onto a (VHS) tape using glue. When a magnet moves in and out of a coil of wire(or near it), electrical current flows through the wire, and therefore windbelt generates electricity. Shape of my magnet is not ideal, thus I will try to get smaller and round-shape magnet which could get in and out of coil. The Key Advantages of Wind-belt over existing micro-wind turbine technology is the fact that it is good at taking power from turbulent wind flows, i.e. in a built up domestic setting, and it is also very quiet in operation.
Unlike PV solar panels, wind turbine generators do not scale down so well. While large wind turbines can generate huge quantities of electricity very efficiently and relatively cheaply, as the size of the wind turbine is reduced, efficiency reduces and cost per generated watt jumps quite enormously.
