BIGGEST POWER PLANT OF ALL

The sun, seen here just before setting, is an atomic furnace that turns mass into energy. Every second it converts 5.87 * 10¹¹ Kg of hydrogen into 5.83 * 10¹¹ Kg of helium, The missing four million tons of mass are discharged into space era .The earth receives only one 2,000-m of this. But in one year this would be to melt 114 feet of ice over its entire space.

ROARING WATER POWER

The Zambesi River flows at the rate of 7.5708*10⁷  liter a minute over Africa's Victoria Falls. This mile-wide cataract on the border between Northern and Southern Rhodesia is 355 feet high, as compared with Niagara's 167 feet. Twenty millions gallons of water falling 355 feet is equivalent to 7.5 * 10⁷ Kg-force meter per second. 

AN ENDLESS SUPPLY OF SURGING POWER AND UNSEEN TREASURE

A magnificent reservoir of energy churns in the oceans that covers 70.8 per cent of the earth. Most obvious, of course, is the rolling, heaving power of wind and tide. Waves, piled up by the wind, remorselessly gouge, rip and amash the shoreline, tearing it away here and building it up there. The tide, in its twice-daily ebb and flow, keep thousands of millions of gallons of water in constant movement. In massive response to the gravitational pull of the tide's surging cycle actually affects the shape of earth as the continents themselves rise and fall ever so slightly.
