Usually, nuclear reactors use multiple stages to turn radiation into electrical energy. For example, first, uranium nuclei are split through nuclear fission, when energy is released in the form of heat and additional radiation. The heat resulted from the nuclear reaction is then used to turn water into steam, which i... |

Computex 2007 is over. But unlike any other computer show (perhaps excepting Cebit), Computex has a way of generating even more questions than answers. And if this phrase sounded a little too cryptic, let me make up for that by saying that a lot of new stuff is being showcased during Computex. Starting with 2000W PSU... |
