The Age has an article on calls to power Australia using solar thermal power and geothermal power from the dead heart - Running on empty: deserts could solve energy crisis. DESERTS could generate enough renewable energy to power Australia, in the process creating unprecedented opportunities for its remote communities, a leading scientist says. Dr Barrie Pittock, a lead author with the UN's Intergovernmental Panel on Climate Change and former head of CSIRO's climate impact group, says deserts could also create a substantial clean energy export industry focused on Asia. He today will tell an Alice Springs deserts symposium that Australia is better placed to develop clean energy than almost any other nation, mainly due to its capacity for large-scale solar and geothermal power plants.

Scientists say that a type of rock found at or near the surface in the Mideast nation of Oman and other areas around the world could be harnessed to soak up huge quantities of globe-warming carbon dioxide.

The designers, engineers, and others tackling the environmental problems we face never cease to come up with amazingly imaginative ideas. Here are some of our favorite recent projects:

It looks more sleek and futuristic (or retro-futuristic, if you're much versed in vintage SF) than other prototypes, a creature more adapted to fictional outer space than to the oceans. But something about its bulbous main compartment led us to wonder if there is enough room inside for seasteaders to muck about with nation-building. Amidst all those noisy condensers and turbine generators and navigational gears, perhaps even inspired by them, they try to formulate the mechanics of a new micro-civilization, new identities and new cultural traditions.

Technology Review has an article on advances in wind turbine technology - Better Wind Turbines. ExRo Technologies, a startup based in Vancouver, BC, has developed a new kind of generator that's well suited to harvesting energy from wind. It could lower the cost of wind turbines while increasing their power output by 50 percent. The new generator runs efficiently over a wider range of conditions than conventional generators do. When the shaft running through an ordinary generator is turning at the optimal rate, more than 90 percent of its energy can be converted into electricity. But if it speeds up or slows down, the generator's efficiency drops dramatically. This isn't a problem in conventional power plants, where the turbines turn at a steady rate, fed by a constant supply of energy from coal or some other fuel. But wind speed can vary wildly. Turbine blades that change pitch to catch more or less wind can help, as can transmissions that mediate between the spinning blades and the generator shaft. But transmissions add both manufacturing and maintenance costs, and there's a limit to how much changing the blade angle can compensate for changing winds.

"Our opponents say, again and again, that drilling will not solve all of America's energy problems - as if we all didn't know that already. But the fact that drilling won't solve every problem is no excuse to do nothing at all.

In an interview released today by Newsmax, Gov. Sarah Palin (R-AK) - Sen. John McCain's (R-AZ) newly minted running mate - was asked for her "take on global warming and how is it affecting our country." "A changing environment will affect Alaska more than any other state, because of our location," Palin said, adding, "I'm not one though who would attribute it to being man-made." DeSmogBlog notes that NASA and the National Academy of Sciences disagree:

A New Jersey company said on Tuesday it will invest $20 million over three years to develop an underground compressed-air storage system for wind turbines and other power sources, a sign of growing confidence in the technology. Energy Storage and Power is a joint ventured formed by energy developer PSEG Global and Michael Nakhamkin, who designed the only compressed air-storage facility in the U.S.

Exxon Mobil agreed to pay out 75 percent of a $507.5 million (276 million pounds) damages ruling to settle the 1989 Exxon Valdez oil spill off Alaska, the Anchorage Daily News reported on Tuesday. Citing both Exxon and the plaintiff's lawyer, the Anchorage Daily News said the oil giant will release about $383 million for distribution to the nearly 33,000 commercial fishermen and others who sued Exxon after the worst tanker crash in U.S. history.

The Arctic Hotel in Ilulissat, Greenland, is a charming little place on the West Coast, but no one would ever confuse it for a Four Seasons - maybe a One Seasons. But when my wife and I walked back to our room after dinner the other night and turned down our dim hallway, the hall light went on. It was triggered by an energy-saving motion detector. Our toilet even had two different flushing powers depending on - how do I say this delicately - what exactly you're flushing. A two-gear toilet! I've never found any of this at an American hotel. Oh, if only we could be as energy efficient as Greenland!

Researchers at the U.S. Department of Energy's Idaho National Laboratory say they have devised an inexpensive way to produce plastic sheets containing billions of nanoantennas that collect heat energy generated by the sun and other sources. They say this technology is the first step toward a solar energy collector that could be mass-produced on flexible materials.

This month, Ecuador will hold the world's first constitutional referendum in which voters will decide, among many other reforms, whether to endow nature with certain unalienable rights. Not only would the new constitution give nature the right to "exist, persist, maintain and regenerate its vital cycles, structure, functions and its processes in evolution," but if it is approved, communities, elected officials and even individuals would have legal standing to defend the rights of nature.

Hawaii has become the first state to require solar water heaters in new homes. The bill was signed into law by Governor Linda Lingle, a Republican. It requires the energy-saving systems in homes starting in 2010. It prohibits issuing building permits for single-family homes that do not have solar water heaters. Hawaii relies on imported fossil fuels more than any other state, with about 90 percent of its energy sources coming from foreign countries, according to state data.

The solar industry is booming. With waves of investment and grants, the solar power industry is for the first time becoming a serious business. New power plants will soon be pumping power out to consumers, while other firms market to sell panels directly to the consumer, providing them with a more direct means of experiencing solar energy.

Sunrgi, a Hollywood-based start-up, came out of stealth mode this week claiming it can collect twice as much sunlight as other photovoltaic designs and convert it to electricity for 5 cents a kilowatt-hour, on par with fossil fuels.

With wind turbine towers popping up on the U.S. landscape at a rate of almost 10 per day, the need for people to maintain and repair them is reaching the critical point. Community colleges in North Dakota and other states are jumping at the chance to help fill that need and develop a niche for themselves at the same time through wind tech programs.

Today, the Environmental Protection Agency (EPA) released a major study by the US Climate Change Science Program synthesizing current scientific knowledge of climate change-induced threats to human health. This information should be critical to the EPA's previous "endangerment finding" for carbon dioxide and other greenhouse gases. However, the EPA Office of Air and Radiation, the branch assigned rulemaking responsibility, evidently did not rely on and did not cite the CCSP report.

Former Vice President Al Gore said on Thursday that Americans must abandon fossil fuels within a decade and rely on the sun, the winds and other environmentally friendly sources of electric power, or risk losing their national security as well as their creature comforts.

Twenty-five years ago, when I was CEO of Intel, I had an unusual experience while visiting a customer. It was during a period of tight availability of microprocessors, our main product. This was not an unusual state of affairs. Supply and demand ebbed and flowed as the computer business had its ups and downs. Sometimes we had too many chips sitting in inventory; other times, like this one, we had too few. My main purpose in visiting was to reassure the customer that we were working hard to boost production and that relief was on the way.
