Small low power 3 phase A.C. / D.C. generator designed for low energy applications using wind or water power. The generator is stackable allowing you to build up a working system of multiple modules to provide the voltage or current required. Connecting a module in parrallel boosts the current and connecting in series boosts the voltage.
Wind generator blades and generator cells are 3d printed.
