Nuclear Energy: Uranium Fission
Beginning of paper
Thousands of years ago human beings learned to make fire. By collecting
and burning wood they were able to warm themselves, cook food, and manufacture
primitive tools. Later, the Egyptians discovered the principal of the sail.
Even more recent was the invention of the water wheel. All of these ....
Middle of paper
.... At present, uranium is only being mined and separated from ore. However, a
huge untapped source is our oceans. Sea water contains 3.3x10^(-9) (3.3 parts
per billion) of uranium, so the 1.4x10^18 tons of sea water contains 4.6x10^9
tons of uranium. All the world's electricity 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 not possible to get all of the uranium
out of our vast oceans ....
