This is a test of a tesla style turbine. Lots of noise from out of balance. An 8" dia bicycle disk brake is on shaft and acting as fan to dissipate energy / power being produced by boiler running at low power around 20kW, so 5 percent or so thermal efficiency of power conversion....to be measured in up coming videos. This is a test of a small turbine for a home power generation system that will use wood chips as fuel and produce heat and electricity for space heating, hot water heating, and home or small business electricity. Future turbines will generate 20kW power for small business operation or local power for a group of off grid homes / cabins.
