Stonehenge, Solar Power, Global Warming, Energy and Noise
Monday, June 2nd, 2008Secrets of Stonehenge unearthed
Now that’s a pretty impressive tombstone. New research suggests that Stonehenge was used as a cemetery for more than 500 years, much longer than previously thought. The new findings also show that people used the area as a burial site long before placement of its trademark stones (or sarsen stones) was complete.
How to harvest solar power? Beam it down from space!
The satellites would electromagnetically beam gigawatts of solar energy back to ground-based receivers, where it would then be converted to electricity and transferred to power grids. The floating power plants could provide round-the-clock clean, renewable electricity.
Scientists Invent Machine to Suck CO2 & Fight Global Warming
Scientists say they have invented a machine that can suck carbon dioxide out of the air – potentially creating a vital weapon in the war against global warming. The blueprint for the CO2 ’scrubber’ raises the prospect of a generation of machines which would help reduce the billions of tonnes of greenhouse gases being pumped into the atmosphere.
The Coming Energy Wars - A Bargain at $200
Oil prices could hit $200 a barrel in the next few months. How the spike changes everything. This spring, America hit a historic point. With average gas prices per gallon edging toward $4, America’s notoriously profligate ways started to change fast. Americans are driving less, using mass transit more, buying fewer gas guzzlers.
How Man-Made Noise May Be Altering Earth’s Ecology
The contamination of biophony may soon become a serious environmental issue — Scientist Bernie Krause says that man-made sounds are already wreaking havoc with animal communication. We worry about the carbon emissions from SUVs and airplanes; maybe we should be equally concerned about the racket they cause.
