Why are light power dense LENR power plants necessary?
A Boeing 747 engine produces 25 megawatts of power per combustion turbine. Twenty-five megawatts is the equivalent of about 33,500 horsepower. The Pratt & Whitney jet engines used in Boeing 747s produce about 55,000 pounds of thrust on take-off, which is the equivalent of around 34,100 horsepower. At 10 megawatts per cubic foot, it would take 2.5 cubic feet of volume to produce the trust needed to power a jet engine. That is 10 cubic feet per 747. A ion engine for a Mars space craft would need about 200 Megawatts to get to Mars quickly. That is about 20 cubic feet of reactor volume.
