Abstract:
1. A machine to convert gravity to mechanical energy and heat, comprising: a) a plurality of piston-in-a-tank with pistons that cycle between an up position ( b) a generator ( c) a top transfer solenoid ( d) a bottom transfer solenoid ( e) a combination retractable stop ( f) a gas breather tube ( g) a door ( h) a pressure equalizing valve ( i) valves to let liquid in ( j) cylinder walls ( k) a heat exchanger ( wherein the machine is immersed in a body of liquid; wherein at position ( wherein as said piston-in-a-tank falls the pressure on the inside and outside of said piston-in-a-tank is equalized by valve ( wherein the piston-in-a-tank fall as a continuous column greatly reducing the drag between the piston-in-tank and the liquid; wherein as the piston-in-a-tank fall they accelerate do to the force of gravity, both the heavy metal weight and the liquid in said piston-in-a-tank build momentum; wherein at position ( wherein said collapsible stop abruptly suspends the fall of said piston-in-a-tank; wherein as the collapsible stop collapses it forces the gas thru valve ( wherein the sump pump with a heavy metal weight ( wherein the piston lock ( wherein the piston-in-a-tank becomes lighter than the liquid it displaces and will float up doing work; wherein the valve ( wherein the piston is attached to the rigid track ( wherein the piston-in-a-tank near the top valves ( wherein the piston floats up, returning said piston to the up position; wherein the piston-in-a-tank becomes heaver then the liquid it displaces and will sink; wherein at position ( wherein the cycle is repeated.
