World is running out of its energy sources. Most recent breakthroughs were simply efficiency improvements. Most renewable energy approaches such as solar, wind… are not capable of supplying for mainstream demand. Also most of them consume wast amounts of land and don’t even produce energy all day long. Nuclear fission is risky and ever decreasing in popularity. One main promise of future is Fusion energy. Which is expected to be lot more cleaner, safer and more productive than fission. However the world is long way away from having sustained fusion, as well as producing positive net energy fusion reaction.
Having said that, sometimes you come across bright sparks of hope in places you least expect. I was searching about nuclear fusion reaction recently after Japan incident and came across this. It’s a table top sustained fusion reactor by a high school kid. His reactor core is made using a cookie jar with some commonly available material. He calls it ‘Star in a Jar‘. Of course he has had some help.
Apparently it’s not that complicated to build one if you know the basics and have some t(h)inkering skills. Most of the knowledge is available at http://www.fusor.net/.
