Cars could run on recycled newspaper, scientists say

Here's one way that old-fashioned newsprint beats the Internet. Tulane University scientists have discovered a novel bacterial strain, dubbed "TU-103," that can use paper to produce butanol, a biofuel that can serve as a substitute for gasoline. They are currently experimenting with old editions of the Times Picayune, New Orleans' venerable daily newspaper, with great success.

Brazilian wind power cheaper than natural gas

The Brazilian authorities have this week confirmed that wind power in the country currently costs less than natural gas, after a series of energy auctions saw wind farm operators undercut other forms of energy generation.

Seventy-eight wind power projects won contracts in last week's energy auctions held by Brazil's National Electric Power Agency, totalling 1,928MW and priced at approximately 99.5 reals (37.4 GB pounds) per MWh.

13-Year-Old Makes A Solar Breakthrough With Fibonacci Sequence : TreeHugger

(...) the Fibonacci sequence: Starting with the numbers 0 and 1, each subsequent number is the sum of the previous two - 0, 1, 1, 2, 3, 5, 8, 13.... These numbers, when put in ratios, happens to show up in the patterns of branches and leaves on trees. Aidan, having been mesmerized by tree-branch patterns during a winter hike in the Catskills, sought to investigate why. His hunch: "I knew that branches and leaves collected sunlight for photosynthesis, so my next experiments investigated if the Fibonacci pattern helped."

One thing led to another, and before you know it, this kid, three years from being eligible for a driver's license, had built a tree-like stand affixed with small solar panelsin the Fibonacci pattern. He compared its ability to collect sunlight to a flat-panel collector. And Nature won.

Summing up his research and imagining the possibilities, Aidan wrote: "The tree design takes up less room than flat-panel arrays and works in spots that don't have a full southern view. It collects more sunlight in winter. Shade and bad weather like snow don't hurt it because the panels are not flat. It even looks nicer because it looks like a tree. A design like this may work better in urban areas where space and direct sunlight can be hard to find."

Water purification unit generates its own energy

"A new biological water purification facility developed by Siemens generates enough methane gas to power its own operations. It also produces much less sludge than conventional systems. The pilot facility for this process, which is located at a site run by Singapore’s Public Utilities Board, has been operating in an energy- neutral manner since June 2010. Now, the city state is building a much larger pilot facility – one that will process 300 times more effluent than its predecessor, or about as much sewage water as is produced by around 1,000 people.

MIT researchers are printing solar cells on sheets of paper

Solar power is a great alternative energy source, but it’s unfortunately a rather expensive one. However, researchers at MIT are working on a new and less-expensive way to make solar cells which involves printing them directly on to fabric or paper."

Bringing light to the poor, one liter at a time | Video | Reuters.com

A bottled liter of water with a few teaspoons of bleach is proving to be a successful recipe for dwellers in the light-deprived slums of the Philippines. The simple technology is spreading sunlight in places where it has never been, and saving residents money at the same time.

New Google R&D Team Charged With Making Renewable Energy Work For The Market

New Google R&D Team Charged With Making Renewable Energy Work For The Market | Fast Company

As new CEO, Larry Page is under pressure to deliver something big. Recently, Malcolm Gladwell argued (in his typically contrarian fashion) that the Internet "search solves problems that aren't really problems":

Can we make a better Google or Bing? Yeah; sure we can. But it solves a problem that isn't really a problem. You cannot point to any area of intellectual activity or innovation that is today being compromised or hamstrung by their lack of access to search technology. Can we honestly go to some scientist to say that the reason you haven't cured cancer is because you don't have access to some information about cancer research? No!

There isn't a problem that's any bigger or more real than generating renewable energy and bringing it to market. If Google can find big ways in just the next few years to solve only a part of that puzzle, turning Google's energy wing into a business remotely as robust as its search and software core, then Page will have delivered something big indeed.
