This invention discloses the efficient, non-polluting generation of electricity through the construction and use of an electric power generating system wherein electricity is generated by utilizing the powerful subsurface undercurrents present near an ocean shoreline. The undercurrent water is caused to cycle internally through a conical shell housing assembly constructed in an upwardly narrowing configuration to produce a nozzle effect within the shell housing. The nozzle effect generates a combined water and air power piston that alternates in a vertical direction within the shell assembly. In both the upward and downward cycles, the power piston impacts a fan blade component that causes the shaft of an electricity generating turbine to rotate and produce electricity.

A wind turbine includes a quartet of pivot shafts that are in paired parallel relationship and transversely mounted on a central drive shaft, each pivot shaft supports a pair of wings at opposed ends thereof, the wings offset by 90°. Each pivot shaft rotates cyclically through 90° to move each wing from a wind-engaging orientation (drive position) in which the wing presents a flat surface approximately transverse to the incident wind, to a minimum drag position (glide position). In addition, the two wings of each pair on a shaft are disposed in planes that are offset by approximately 90° about their pivot shaft, so that one is in the drive position while the other is in the glide position. The wings of each pair of pivot shafts have wings at the ends thereof that open into the drive position at the same time and rotational angle of the turbine. A backstop at the site of each drive position supports the wind load and transfers its force to the central drive shaft.

Production of mechanical/electrical energy from heat energy with and by the use of buoyancy factor on evaporation or sublimation and condensation

Номер: US20200095896A1
Автор: Sudarshan K.C.

There are various source of heat energy. Amongst the various sources Solar energy, waste heat form garbage, waste heat from transformers, waste heat from chemical reactions, waste heat from plant and machinery, heat from geo-thermal or the vast heat energy lying in the seas and oceans are some of the major ones which are free and unused. Apart from these, we can also produce heat energy from fuels like fossil fuels, hydrogen gas, forest products etc. A lot of heat energy is being wasted and though converted to mechanical or electric energy it is not that efficient. However, using the evaporation or sublimation and condensation process brought about through difference in temperature and the use of buoyancy factor to increase the efficiency of the energy production, the heat energy can be converted to mechanical or electrical energy in excess of hundred percent. Moreover, heat energy obtained from hydrolysis of some chemicals like salts or hydroxides and their dehydration for reuse or the heat stored as latent heat on melting of salts can be utilized for huge storage of energy for some months or more and use it through this invention method. The energy lying in the water under the oceans during winter can be easily utilized for production of huge energy when there are very low (freezing) temperatures on the surface of the earth.
