20100025999 | Ocean wave electricity generation - This invention relates to electricity generation from the ocean wave by use of mechanical systems, submerged or on surface, collecting energy day and night regardless weather condition in a way similar to the way of collecting energy by use of solar panels or wind mills, without contacting the salty ocean water. The principal mechanism invented is as follows. Swinging of a heavy mass due to the ocean wave generates torque that sways gear wheel in clockwise or counterclockwise, thus transmitting the torque energy to two gear wheels that separate clockwise swing and counterclockwise swing via two sets of spring-piston clutching system and by use of gear chain, either converting clockwise swing to counterclockwise swing or vise versa such that the back and forth motion of the mass transforms into unidirectional rotation that rotates the rotor of electricity generator. | 02-04-2010 |
20100301609 | River-Flow Electricity Generation - This invention relates to electricity generation from the river flow by use of mechanical systems, collecting energy day and night regardless of weather condition in a collective manner while isolating a part of the system within a water-proof container. The mechanical system invented generates a force imbalance and thus generates torque to rotate a shaft at a high revolution rate. Two approaches are introduced to create the force imbalance. The first one mechanizes vane operation on a wheel such that pressure builds on one side of the wheel while no pressure builds on the other side. The second one is a “Water-Box” that has an open front side and a door such that pressure builds on the door at one side of the wheel while no pressure builds on the other. Thus, the force imbalance is created and torque is generated to rotate a shaft at a high rate of revolution. | 12-02-2010 |
