Cyclone Power completes testing of biofuels-compatible, external combustion, steam engine

In Florida, Cyclone Power Technologies announced that it had completed performance tests of its external combustion engine for Raytheon Integrated Defense Systems (IDS). According to Cyclone, tests demonstrated that water-cooled Mark II engine achieved thermal efficiencies over 30%. Operating at temperatures of 1000°F and steam pressures of 1150 psi, the compact 98 lbs Mark II ran at 2133 rpm and produced 13.4 hp and 33 ft-lbs of torque at a diesel fuel burn rate of 0.8 gal/hr.

The Cyclone Engine is a modern steam engine, designed to achieve high thermal efficiencies through a compact heat-regenerative process, and to run on bio-diesel, syngas or solar.
