The great Jhonny of Auroville shows how to make 'dosa' batter using renewable energy. he burns biomass, heats up a Stirling engine, the great and veteran ST-5 engine, and makes it grind and crush batter used for making the south Indian staple, the famous DOSA!! He runs the engine every Saturday to make free Lunch for any and all visitors on Sunday. Great Man, Great engine.
