N. Peter Evans: You just expressed the DREAMS of many "fools ! ?". 1)You say: >Say I want a 2kW system and I have plenty of potential is the stream. 2)Then: >For a turbine I could make a banki out of wood and some sheet metal. 3)Then: >For a generator use a truck alternator from a junkyard 4)Then > Is this practical?
NO ! Why ?. Because 2 & 3.
