The best place for
solar thermal power plant is desert area but availability of water is major problem for steam generation and cooling.
Only, the gravity is the free input fuel present everywhere on earth and will available till the end of earth. Gravitational
energy is very easy to convert in mechanical motion for power generation. The capital required for installation of power
generation unit is very less and also it can be install anywhere on earth. The use of gravitational energy for power
generation is eco friendly and will helps to control the problems like global warming.
