1. Nuclear Fission, Fusion, and Hydrogen Fuel Cells By: Cecily Leahy and Peter Knox

2. Nuclear Fission:  Fisson is the splitting of uranium atoms to release energy.  Fission creates nuclear waste. Fission is a more practical appliction to use at the moment. It gives off more energy. Nuclear Fusion:  Fusion is the combination of atoms to release energy. Fusion has no nuclear waste after being fused. Fusion is still being developed to be used without wasting so much energy. Difference Between Nuclear Fusion and Fission

3. Nuclear Fission Facts  A neutron is shot into an atom of Uranium-235. Uranium-235 is a fissile material, allowing fission possible.  The extra neutron makes Uranium-236, an unstable form of Uranium, start fission, breaking it down into nuclear waste and energy. Most byproducts of fission is radioactive with half-lives measuring from seconds to years. It approximately takes 17,000kg of fossil fuels to produce the same amount of energy as 1kg of Uranium fissile fuel.

5. Nuclear Fusion Facts High temperatures are needed to fuse atoms. Takes more energy to fuse than energy given off. Scientist are trying to do "cold fusion", fusion that requires little to no energy to fuse the atoms together.

6. Nuclear Fusion Reactor

7. Nuclear Fusion Reactor Nuclear fusion reactor bonds Uranium atoms together. Plasma in reactor gets the atoms hot enough to fuse together.

9. What is Hydrogen Fuel Cell? Hydrogen fuel cell are hydrogen atoms that are used as a source of engery to in order to produce electricity. It is among the smallest and most abundant element in the universe. Hydrogen is only in pure form when with water, which is why a process called electrolysis to sperate the hydrogen and then use the electrons from the hydrogen to create electricity.

10. Benefits of Hydrogen The emissions from hydrogen fuel cell process creates water and heat as the emissions, therefore not contributing to greenhouse gases or decreasing the ozone layer. Hydrogen energy can be used on all levels. From as small as a music device to running an office building.
