Has anyone see heard of that boat called the Orcell that uses solar, wind, and water current generators in addition to diesel to run?
How effective is it to take a tiny pager-type motor and stick some kind of fan blades or propeller on it to get it to generate power from the wind (or water for that matter)? In another thread in another section someone said that it wouldn't work very well because the motor is designed to be efficient at around 3000RPM.
The idea is to charge up a bank of supercapacitors to power electronics and the ocassional sail winch servo or rudder every now and then (miniature model-sized boat). It'd be nice to be able to augment the solar cells with wind power or water current power, with wind sails doing most of the movement work.
