23/05: Water Turbine for Home Use
What if every time that you flushed your toilet you could generate just a little bit of power? That is the idea behind the Benkatine Turbine by Leviathan Energy, which aims to get power from any pipe that water rushes through. So not only could you install this within a municipal system, but according to the company, you could get power from the water rushing down your gutter drains!

Bob Barlow, Wayne Gerdes, Rick Reece, and Dan Kroushl drove 47 hours for a total of 1,397 miles on 12.87 gallons of gasoline in an unmodified Toyota Prius. How did they do it?
Last week, three of the world's biggest oil companies reported record-breaking quarterly profits in excess of $27 billion. It's pretty hard to fathom that kind of money - but what is easier for the rest of us to see in real terms is also breaking records: the cost of a gallon of gas.
07/05: Plastics Derived from Plants
Australian researchers are a step closer to turning plants into ‘biofactories’ capable of producing oils which can be used to replace petrochemicals used to manufacture a range of products.
Using sophisticated unmanned aircraft, research scientists at Scripps Institution of Oceanography, UC San Diego hope to assess Southern California's potential for climate change and better understand the sources of air pollution.
Funded by the California Energy Commission, the California AUAV Air Pollution Profiling Study (CAPPS) uses autonomous unmanned aerial vehicles (AUAVs) to gather meteorological data as the aircraft fly through clouds and aerosol masses in Southern California skies. The flights will take place at Edwards Air Force Base near Rosamond, Calif. The study began its first sortie of data-gathering flights in April 2008.

NEW YORK (Reuters) - A proposal by Texas Gov. Rick Perry to waive half of the renewable fuel standard for ethanol has raised the ire of some ethanol proponents, who say it could add more than a dollar per gallon to the cost of gasoline across the country.
With U.S. gasoline prices edging toward the recently unimaginable price of $4 a gallon, consumers are beginning to drive less and energy efficiency is again a hot topic. But the pain caused by high oil prices is nothing like what looms as an even more basic and essential natural commodity — water -- faces dwindling supplies and growing demand. As essential as it is taken for granted, water is The Next Oil.
Solar electricity is about to get much cheaper, industry analysts predict, because a shortage of the silicon used in solar panels is almost over. That could lead to a sharp drop in prices over the next couple of years, making solar electricity comparable to power from the grid.
High demand generated by government subsidies worldwide and a shortage of processed silicon have kept prices for solar-generated power much higher than average electricity prices over the past few years. Solar power is more than three times the cost of electricity from conventional sources, according to figures from the industry tracking firm Solarbuzz and the United States' Energy Information Administration. Solar power cost about $4 a watt in the early 2000s, but silicon shortages, which began in 2005, have pushed up prices to more than $4.80 per watt, according to Solarbuzz.
Crystalline silicon has long been the staple of the semiconductor industry. But it's also the active material in the most common type of solar panel, and the increased use of solar power has led to the shortage of the material. Indeed, the growth in silicon production hasn't kept pace with the rise in solar power. "It takes about two or three years to add capacity," says Travis Bradford, an industry analyst for the Prometheus Institute. The shortage has been severe enough to drive up silicon prices to more than 10 times normal levels, to $450 a kilogram, adds Ted Sullivan, an analyst at Lux Research.
