Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. In my attempt to escape city slicker yuppies (you know the kind, the ones that like to blab loudly on their cell phone while they work on some business administration degree in a cyber cafe somewhere in Trendyland.) and their light pollution, I found a great piece of remote property.

Last updated at 21:09 15 September 2007 It sounds too good to be true - not to mention the fact that it violates almost every known law of physics. But British scientists claim they have invented a revolutionary device that seems to 'create' energy from virtually nothing. Their so-called thermal energy cell could soon be fitted into ordinary homes, halving domestic heating bills and making a major contribution towards cutting carbon emissions. Scroll down for more... Hot stuff: Ecowatts boss Paul Calver with the device How this 12inch miracle tube could halve heating bills
[ Run time: 2:05 min ] I hope you enjoy this short video of Shawn Frayne, a young inventor that has created this device to generate, on the micro-scale, energy for LED lights and radios in developing countries. This is the first approach that uses aeroelastic flutter to create super cheap electricity. We’re talking about changing the way wind energy is harvested and captured. Frayne won a 2007 Breakthrough Award from Popular Mechanics, and he deserves it. This incredible technology is 10-30 times more efficient than the best micro-turbines. So, Frayne hopes to fund third-world distribution of the Windbelt through sales in first-world applications. Windbelt Micro-wind, 10 Times Cheaper Wind Energy!!
In collaboration with Norman Rostoker from UC at Irvine, we have designed a novel type of fusion reactor, the Colliding Beam Fusion Reactor (CBFR). It uses protons (p) and boron-11 (11B) for fuel. Fusion reactions produce only three helium-4 (4He) nuclei, and nearly 9 million eV energy. C:\IMAGES\OMNIPAGE\DATA\hm2.htm
