Air-powered appliances are an alternative for those living off the grid. Compressed air is stored in large air tanks, some the size of an LP tank. Air Compressors are powered by gasoline, diesel, motors or utilize wind and water wheel power. Without leaks at the fittings, the air tank will hold hours of use and takes only a few minutes to re-pressurize.
Appliances have been converted by an Amish shop who specialize in sizing airpower motors to use in place of standard electric motors. Air motor conversions are very expensive but with fewer parts to go bad they will likely outlast electric motors.
