The Story of Science – Can We Have Unlimited Power (BBC Documentary)
We are the most power-hungry generation that has ever lived. This episode tells the story of how that power has been harnessed — from wind, steam and from inside the atom. In the early years the drive for new sources of power was led by practical men who wanted to make money. Their inventions and ideas created fortunes and changed the course of history, but it took centuries for science to catch up, to explain what power is, rather than simply what it does. This search revealed fundamental laws of nature which apply across the universe, including the most famous equation in all of science, e=mc2.
