Abstract
An energy conversion system includes a first mechanical system for converting reciprocating motion to rotary motion, a second system formed of belts and pulleys connected to said first system and driven by said rotary motion to lift a weight in response to said rotary motion from a first position to a second position and allow the weight to return to said first position under the influence of gravity. A rotary electrical is driven by the second system through a transmission means connected to the second system to create electricity only while the weight is returning from its second to its first position.
Claims26
An energy conversion system comprising a carriage mounted for linear reciprocal motion;
- a plurality of one way drive means mounted on said carriage;
- a pair of pulleys/sprockets mounted in fixed positions adjacent the ends of the path of travel of the carriage, a drive belt/chain engaged with said pair of pulley/sprockets, said plurality of drive means being engaged in a predetermined pattern with said drive belt/chain for driving the drive belt/chain in a single direction during reciprocation of the carriage;
- at least a second pair of pulleys/sprockets located in vertically aligned relation, a weight lifting belt/chain engaged with said second pair of pulleys/sprockets, weight means secured to said weight lifting belt/chain and over running clutch means engaged between one of said first pair of pulley sprockets and one of said second pair of pulley sprockets for driving said weight lifting belt/chain in a first vertical direction to move said weights vertically to pass over the top most of said second pair of sprocket/pulley and for allowing said weight to free fall and drive said weight lifting belt/chain in the same direction under the influence of gravity;
- a rotary operated electrical generator and means for transferring the rotational motion of at least one of the second pair of pulley/sprockets to said electrical generator for producing electricity only during downward motion of said weights.
An energy conversion system comprising first means for converting reciprocating motion to rotary motion, second means connected to said first means and driven by said rotary motion for lifting a weight in response to said rotary motion from a first position to a second position and for allowing said weight to return to said first position under the influence of gravity, a rotary electrical generator, and transmission means connected to said second means for driving said rotary electrical generator to create electricity only while said weight is returning from said second to said first position.
An energy conversion system comprising first means for generating a reciprocal motion, second means for converting said reciprocal motion to rotary motion;
- a weight;
- third means connected to said second means and driven by said rotary motion for lifting said weight in response to said rotary motion from a first position to a higher second position and for allowing said weight to return to said first position under the influence of gravity, a rotary electrical generator, and transmission means connected to said third means for driving said rotary electrical generator to creates electricity only while said weight is returning from its higher second position to said first position.
