CLIMATE SCIENTISTS NEED TO GET OFF OF THE GOVERNMENT DOLE AND GET REAL PRODUCTIVE JOBS WHERE THE ACTUALLY CONTRIBUTE VALUE TO OTHERS.

The problem with batteries is that they often contain toxic chemicals that can leach out into the environment. But what if the chemicals were completely natural? Professor Chungpin Liao and researchers at Coherent Control Laboratory in Taiwan are thinking in that direction. They have invented an organic battery powered by chlorophyll - the green-colored photosynthetic pigments found in most plant life.

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.

The (UK) Telegraph has an article on the Vivace tidal / current power device I mentioned recently - Ocean currents can power the world, say scientists The technology can generate electricity in water flowing at a rate of less than one knot - about one mile an hour - meaning it could operate on most waterways and sea beds around the globe. Existing technologies which use water power, relying on the action of waves, tides or faster currents created by dams, are far more limited in where they can be used, and also cause greater obstructions when they are built in rivers or the sea. Turbines and water mills need an average current of five or six knots to operate efficiently, while most of the earth's currents are slower than three knots.

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.

A fungus that lives inside trees in the Patagonian rain forest naturally makes a mix of hydrocarbons that bears a striking resemblance to diesel, biologists announced today. And the fungus can grow on cellulose, a major component of tree trunks, blades of grass and stalks that is the most abundant carbon-based plant material on Earth. "When we looked at the gas analysis, I was flabbergasted," said Gary Strobel, a plant scientist at Montana State University, and the lead author of a paper in Microbiology describing the find. "We were looking at the essence of diesel fuel."

Scientists working at Arizona State University's Laboratory for Algae Research & Biotechnology hope that tiny algae will be able to fuel jumbo jets. Now, their research is being spun-off as a $3 million research and commercialization collaboration between Heliae Development and Science Foundation Arizona to develop, produce and sell kerosene-based aviation fuel derived from algae. The researchers say they've already moved their work from the lab bench to a pilot-scale demonstration and production project.

Efforts to develop a massive environmentally friendly power plant combining photovoltaic generators and windmills that will float on the sea are progressing well, according to a team of scientists at Kyushu University. The planned plant will measure two kilometers by 800 meters and will be equipped with light-emitting diodes that shine light into the sea to promote seaweed growth, which in turn will absorb carbon dioxide and attract fish.

It's an uncomfortable thought: Human activity causing the extinction of thousands of species, and the only way to slow or prevent that phenomenon is to have smaller families and forego some of the conveniences of modern life, from eating beef to driving cars, according to Stanford University scientists Paul Ehrlich and Robert Pringle.

New satellite measurements show that crucial sea ice in the Arctic Ocean has plummeted to its second-lowest level on record. Arctic ice always melts in summer and refreezes in winter. But more and more ice is being lost and not recovered. The National Snow and Ice Data Center in Boulder, Colorado, announced Wednesday that the extent of sea ice in the Arctic is down to 2.03 million square miles. The lowest point on record is 1.65 million square miles set last September. With about three weeks left in the melt season, the record may fall, scientists say.

Behind the headlines, scientists warn that climate change is already hitting New Mexico Signs of ancient life are scattered across the mesas above the Chama River as it winds along highway 84 in northern New Mexico. The ground here is strewn with pieces of black and white pottery, and bumps and divots in the soil reveal the lines of stone rooms and walls.

CAMBRIDGE, Massachusetts (Reuters) - A U.S. scientist has developed a new way of powering fuel cells that could make it practical for home owners to store solar energy and produce electricity to run lights and appliances at night. A new catalyst produces the oxygen and hydrogen that fuel cells use to generate electricity, while using far less energy than current methods.

The first meeting of the International Agrichar Initiative convened about 100 scientists, policymakers, farmers and investors with the goal of birthing an entire new industry to produce a biofuel that goes beyond carbon neutral and is actually carbon negative. The industry could provide a "wedge" of carbon reduction amounting to a minimum of ten percent of world emissions and possibly much more.

Scientists mimic essence of plants' energy storage system. In a revolutionary leap that could transform solar power from a marginal, boutique alternative into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn't shine.

A four-square-kilometre chunk has broken off Ward Hunt Ice Shelf - the largest remaining ice shelf in the Arctic - threatening the future of the giant frozen mass that northern explorers have used for years as the starting point for their treks. Scientists say the break, the largest on record since 2005, is the latest indication that climate change is forcing the drastic reshaping of the Arctic coastline, where 9,000 square kilometres of ice have been whittled down to less than 1,000 over the past century, and are only showing signs of decreasing further.

Warnecke, a researcher at the U.S. Department of Energy's Joint Genome Institute in Walnut Creek, California, has been generating lots of attention lately for his work with termites. The insects are remarkably efficient at turning cellulose into sugar-the first step in making fuel from plants like switchgrass or poplar trees. Scientists can't compete with termites.

We are familiar with the notion of getting an expert second opinion when an expert medical specialist has diagnosed life threatening circumstances. However a second opinion that is a bit more optimistic simply decreases the perceived odds of death somewhat - the dire initial prediction remains.

United Nations Secretary General Ban Ki Moon has warned that without a comprehensive international agreement to reduce the greenhouse gas emissions that lead to global warming, humanity faces "oblivion." "The world's scientists have spoken with one voice: the situation is grim and urgent action is needed," Ban said. "The situation is so desperately serious that any delay could push us past the tipping point, beyond which the ecological, financial and human costs would increase dramatically.

A tiny rectangle superimposed on the vast expanse of the Sahara captures the seductive appeal of the audacious plan to cut Europe's carbon emissions by harnessing the fierce power of the desert sun. Dwarfed by any of the north African nations, it represents an area slightly smaller than Wales but scientists claimed yesterday it could one day generate enough solar energy to supply all of Europe with clean electricity.

The incandescent lightbulb that wastes 90% of the electricity as heat is dying, we all know that. But a new breakthrough in solid state lighting might also kill compact fluorescent lightbulbs (CFLs) faster than some expected. Scientists at Purdue University have figured out how to manufacture LED solid-state lights on regular metal-coated silicon wafers (more details below). What this means is: much lower costs.
