  1. Fusion Nuclear Energy

  2. So what is it? • Sun produces vast amounts of energy by combining 4 nuclei of hydrogen to form a helium nucleus and 2 positrons • The mass of the helium nucleus and the 2 positrons is less than the 4 hydrogen nuclei • The excess mass available in this reaction is converted into energy, according to the weirdo Einstein and his formula

  3. Why is that good? • Well, if we could duplicate this on earth, we could have energy forever because there is an infinite amount of hydrogen on earth: our planet is mostly water and every molecule of water contains 2 atoms of hydrogen • Also: the end products of the fusion of hydrogen into helium produces neither radio active nor reactive end products so the problem of waste storage disappears

  4. So what’s the prob y’all? • It is possible to design fusion reactors so that safety is assured • Trouble: • To duplicate what goes on in the sun on earth is a formidable engineering problem • REALLY? – YES • The difficulty of bringing the sun down to earth has to do with the fact that hydrogen nuclei protons, are an electrically positively charged particles.

  5. MORE STUFF • For fusion reaction to occur the protons have to closely approach each other • Positively charged articles repel each other with a force that increases as they get closer to each other • Inorder to overcome this repulsion, the hyrdrogen nuclei must rapidly approach each other! • How Rapidly must they approach each other?...

  6. As fast As a CAT

  7. No but really • This requires a temperature of 100 – 200 million degrees • THAT’S HOTT!!!

  8. … • See, even dumb ass Paris Hilton agrees. • The Problem is finding a container that can house the protons at this temperature long enough for fusion to take place
