Today's Snapshot considers breakthroughs in Nuclear Fusion energy, Graphene's amazing new conductivity and programmes to grow biofuels in the desert. The dream of a completely clean, high powered and almost limitless renewable energy source is getting closer. Nuclear Fusion is the process by which atoms are compressed to such a degree that their nuclei fuse, releasing a huge amount of energy. Essentially it is the opposite of current Nuclear Power, based on fission whereby large nuclei are torn apart to release energy. This is the process which happens in stars, turning Hydrogen into the heavier Helium, and all other natural elements.
