The document describes Andy Rotary engine specifications for engines of various sizes from 10 cm to 600 cm in diameter. It lists the cylinder diameter, thickness, volume, horsepower output, required fuel per hour, estimated carbon emission reductions per year, and cost for each engine size. The rotary engine works on all fuel types including solids, liquids, gases, and biofuels. It claims to be more efficient than other engine types, requiring only 1/3 the fuel per horsepower and producing 2/3 less carbon emissions.
