US Military Advances Solar Power

Via nc links, some good news on the solar front:

Field patrols will soon have almost weightless solar blankets as well. These will be able to capture a once unthinkable 35pc of the sun's light as energy with thin membranes, a spin-off from technology used in satellites.

This new kit is a military imperative. Taliban ambushes of supply convoys are a major killer. The Pentagon says the cost of refueling forward bases is $400 a gallon.

The US Naval Air Weapons Station already relies on a 14 megawatt array of solar panels in California's Mojave desert for a thrid of its power. Pearl Harbour will soon follow as the Pentagon goes off-grid, better shielded from enemies.

The US Navy will derive half its energy supply from renewables by the end of this decade, according to a report entitled Enlisting the Sun: Powering the U.S. Military with Solar Energy, by the US solar industry (SEIA). It may be a stretch to say that the US Naval Research Laboratory is the vanguard of the world's green revolution, but not a big stretch.
"The US Defence Department is racing ahead. This could be like the semiconductor industry in 1980s where the military changed the game," said Jeremy Leggett, chairman of Solarcentury.
Nor is the Pentagon alone. Grant lists from the "SunShot Initiative" of the US Energy Department show that America's top research institutes are grappling with each of the key issues that have bedevilled solar energy for so long.
Los Alamos - home of the Manhattan Project - is working on smart grids and better ways to capture excess electricity produced in peak sunlight hours. The Argonne labs are working on thermal energy storage to overcome "intermittency", the curse of solar and wind.
Oak Ridge is testing coatings that increase durability of solar panels eightfold. The National Renewable Energy Laboratory is working on a CO2 power cycle that could achieve 90pc thermal efficiciency and does not require water, transforming the propects of desert solar.

The prediction is for all this research to break many of the cost barriers which have limited solar energy thus far.
