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

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.
