Thousands of  historic period ago  piece  cosmoss learned to  bring fire.  By collecting and  ardent wood they were able to  fond(p) themselves,  wangle food, and manufacture primitive tools.  Later, the Egyptians discovered the principal of the sail.   hitherto  much recent was the invention of the water wheel.  All of these activities  hire  miscellaneous forms of energy-biological, chemical, solar, and hydraulic. Energy, the ability to do work, is essential for meeting  elemental human  leads, extending the life expectancy, and providing a rising living standard. This is where the need for  thermonuclear power comes in.  Uranium fission is  almost a  one million million times more  effectual than the common practice of burning  combust or oil.  For comparison, coal combustion produces about 20-30 MJ/kg of heat energy  part   uracil, in a  warm breeder reactor, produces more than 24,000,000 MJ/kg (Energy 27).  Those numbers alone  are astounding. Uranium is also  abounding, thank t   o recent discoveries of large reserves.  At present,   uracil is only being mined and separated from ore.  However, a  extensive untapped  bloodline is our oceans.  Sea water contains 3.3x10^(-9) (3.3 parts per billion) of uranium, so the 1.4x10^18   lots of  sea water contains 4.6x10^9 tons of uranium. All the worlds electrical energy usage, 650GWe could therefore be supplied by the uranium in sea water for 7 million years(Energy 25).

  This is a only a theoretical number because it is  non  likely to  name all of the uranium out of our vast oceans.  Also, it does not include the fact that in that many years, half of    the uranium will no  long exist due to  hot!    decay.  So, at worst, we would get about 2 million years of power from it.  Thorium is  other element than can be used in nuclear reactors.  Thorium is approximately  foursome times more abundant than uranium.  It is obvious that we are...                                        If you want to get a full essay,  edict it on our website:
