By contrast, the Bladon Micro Turbine Genset (MTG) generates up to 12kW of power thanks to a small high speed microturbine spinning on a shaft with an alternator all weighing less than a total of 25kg, functioning like a turbocharger. This microturbine power plant rests on 4 patented airbearings using atmospheric air pressure to suspend the shaft in an envelope of air. The microturbine shares the same rotating shaft as the alternator and runs at high and variable speeds of up to 140,000 rpm.
