Water is heated to 230 degrees F. to make steam by solar heat or by a least costly available fuel of choice. Steam is then condensed by use of a cooling fluid (water) which forms a vacuum in the entire space of a cylinder.
Atmospheric air pressure, which is free of cost, exerts force to fill the empty cylinder. When the valve to the cylinder opens, air under pressure pushes the piston in the cylinder end-to-end with great force in a power stroke.
Twin piston rods are bolted together which makes possible the intake-of-steam stroke in one cylinder during the power stroke action in the twin cylinder.
Strokes alternate in the cylinders at a rapid rate -- an average of 120/min. The piston power stroke force in a 6" diameter piston is about 400 lbs. The power product is 48,000 lbs. - equivalent of 1.4 horsepower.
Thus solar heat is changed to horsepower. Solar heat is clean, green, with no air pollution. Steam may come from cogeneration which uses "waste steam" at a low cost. The Bishop STV Engine requires the lowest pressure of any engine using steam. It uses only 1 - 5 psi. to fill a cylinder with steam.
- Additional fuels are usable: ethanol, methane, geothermal steam
- Computer directed valves control the engine
- Computer mode engine operation is automatic
- Engine operates on utility generated 120, or 240 VAC
- Engine operates on 12 or 24 VDC battery power
- World-wide operation power output is available using sunshine, water, and adequate air pressure
- Licensed development brings add-ons and further patents
- Engine power can be increased by using cylinder/piston diameters larger than the 6" diameters of the prototype engine
- Power can be greatly increased by using 2, 3, 4, 6+ cylinders/pistons
