Hi all, we are looking at alternative energy sources here in Bali for a number of applications from commercial to residential and I'm wondering if any of you have experimented with vortex power? If so, what results have you obtained, what efficiencies over hydro-electric turbines, what problems have you encountered with vortex approach? If you have any recommendations regarding the best equipment for this type of power generator I would also appreciate some info on that. Thank you.
