Energy Tower: Power for 15 Earths? Researchers have designed a product that its inventors claim could easily produce between 15 and 20 times the total electricity the world uses today. Not only that, it could also be used as a desalination device and may be able to reverse the effects of global warming. Those are pretty big claims, but the researchers from the Technion - Israel Institute of Science seem confident that the "Energy Tower" could be a major solution to the world's problems.

Why We Cant Clean Up the Pacific Gyre Over the next few years you are going to hear a lot of claims about programs to clean up the Great Pacific Garbage Patch. The floating island of plastic garbage twice the size of Texas. The trash patch. The area Captain Charles Moore discovered ten years ago. Don’t be fooled! The Pacific Garbage Patch is not an island.

Bill Moyers: Ending the Silence on Climate Change Ending the Silence on Climate Change from BillMoyers.com on Vimeo. Remember climate change? The issue barely comes up with any substance in our current political dialogue. But bringing climate change back into our national conversation is as much a communications challenge as it is a scientific one.

Science News Headlines Developing Science News Facebook Twitter Tian Tian failed to mate naturally so has been artificially inseminated The Searl Effect Generator - Ultimate Overunity? undefined Searl Effect Technology The Searl Effect Generator (SEG) is a magnetic diode, and what one may consider one of the original "Free Energy" Devices. MythBusters Filming is based in San Francisco, though some elements of production are done in Artarmon, Australia. Planning and some experimentation take place at Hyneman's workshops in San Francisco; experiments requiring more space or special accommodations are filmed on location, typically around the San Francisco Bay area and other locations in northern California, going elsewhere when required, such as Florida for alligator experiments, or Africa for shark and elephant myths. During the second season, members of Savage's and Hyneman's team ("The Build Team") were organized into a second team and now generally test myths separately from the main duo and operate from another workshop.

According to Searl, who built nearly two dozen of these in the 1960's, the electrons flow from the middle to the periphery where they can be picked up either as AC or DC current. If the load is too great, a superconductive effect kicks in, resulting in an anti-gravitic effect.Image source: The Searl Solution. Bad Astronomy Well now, this is an interesting discovery: astronomers have found what looks like a "super-Earth" – a planet more massive than Earth but still smaller than a gas giant – orbiting a nearby star at the right distance to have liquid water on it! Given that, it might – might – be Earthlike. This is pretty cool news. We’ve found planets like this before, but not very many! And it gets niftier: the planet has at least five siblings, all of which orbit its star closer than it does. Now let me be clear: this is a planet candidate; it has not yet been confirmed.
Journey Into Amazonia Green Treasure - The Useful Plants of the Amazon Valley by Michael J. Balick, Ph.D. Since the earliest adventurers explored the Amazon Valley, their quest has been for its treasures -- minerals, oil, animal skins, precious stones and metals, to name a few. At times, they have succeeded -- gold, emeralds, petroleum, and other raw materials so important to Western civilization have been exported from this vast region. However, by "taming" the forest and extracting its wealth, biological diversity has become the victim. Gold miners have polluted the Amazon and its tributaries with their mercury and other chemicals; the search for iron and aluminum has destroyed huge areas of wilderness, converting verdant habitats to wasteland; and industrial ventures have turned millions of acres of pristine rain forest to desert-like habitat - all in the name of prosperity and economic return.
BBC - Earth News - The decade's top ten new species Small but able swimmer As 2010 draws to a close, scientists have been looking back over the array of new species that have been discovered since the beginning of the century. Some of the weirdest and most scientifically wonderful are featured in a BBC Documentary, Decade of Discovery. The film-makers collaborated with Conservation International to make the documentary, which has whittled down nature's top ten revelations. So here is a shortlist of many of the team's favourite new species, listed in reverse order according to how unique, special and surprising they are.
Divers Free Whale and Receive Rewards of Love The Whale...If you read a recent front page story of the San Francisco Chronicle, you would have read about a female humpback whale who had become entangled in a spider web of crab traps and lines. She was weighted down by hundreds of pounds of traps that caused her to struggle to stay afloat. She also had hundreds of yards of line rope wrapped around her body, her tail, her torso and a line tugging in her mouth.
