Waste Heat Recovery Application

Using the wasted heat (exhaust and cooling fluid) from a diesel generator, the SolarHeart© Engine could provide as much as a 20% gain in power. For military and remote power applications where the effective price for fuel can be as high as $15 per gallon, this new boost in efficiency is extremely valuable.

The Diesel Generator Situation

• Diesel Gensets used for remote electrical supply Military, intermittent rural, remote base load (to 5MW)
• Reciprocating engine with 30% to 40% net efficiency Deliver 11 – 14 kWh per gallon of fuel
• Dependable, rugged, established technology
• Diesel Genset Issues Only 30% to 40% of chemical energy harnessed ~40% to exhaust stack, ~25% to cooling, ~35% power
• Fuel price volatile Fuel delivery often difficult Required maintenance is frequent
