A heat absorbing radiator and a gas turbine engine or a reciprocating piston engine are used to recapture and reconvert wasted heat energies into electric power and finally into hydrogen-deuterium fuel by having the engine's tailpipes submerged in cold compressed air inside the heat absorbing radiator pipes in reverse air flow to further drive the same engine. In order to capture fusion heat energy a hydrogen bomb is detonated in deep ocean to catch the flames by the water and the hot water energizes compressed air inside heat absorbing radiator pipes. In order to produce fusion energy an electric arc is passed thru / across liquid or gaseous deuterium by an electro-plasma torch and by a sparkplug in an internal combustion engine, or by detonating a dynamite inside liquid deuterium. Diamond is produced by placing carbon inside a hydrogen bomb which is then detonated in deepwater. Deuterium fusion flame is used first in smelting glass into large structural sizes before running an engine.
