Sailing ships once carried much of the world’s cargo across the seas, until canvas sheets were replaced by low-grade “bunker” oil. Now it appears that wind power is about to make a comeback, in the form of rigid “sails” that double as solar panels. The patent-pending technology, called the Aquarius … [continued]

Somewhere in Davis, California the ghost of a dog is smiling. The notorious Frontier Fertilizer Superfund site in that city was supposed to take 150 years to clean up using energy-gobbling pumps and treatment equipment. The contamination started back in 1972 but only came to light in 1983, when a … [continued]
A University of Arizona engineering team led by Roger Angel has designed a new type of solar concentrator that uses half the area of solar (PV) cells used by other optical devices and delivers a light output/concentration that is over 1000 times more concentrated before it even hits the cells. … [continued]
New Hampshire’s newly elected veto-proof Republican majority is swiftly consolidating the pro-pollution agenda provided by oil billionaires Charles and David Koch, the heads of Koch Industries. The New Hampshire House passed HB 519 by 246-104 on Wednesday, repealing its membership in the Regional Greenhouse Gas Initiative (RGGI), after a successful … [continued]

In the 20-state area that participates in a cap-and-trade program to reduce emissions of nitric oxide (NOx) from power plants, NOx emissions have declined dramatically. The reduction is visible even from space, scientists reported as long ago as in 2006, in satellite images of the Northeastern United States. The hard … [continued]
