Plasma astrophysicists at the University of Warwick have found that key information about the Sun storm season is being broadcast across the solar system in a fractal snapshot imprinted in the solar wind. This research opens up new ways of looking at both space weather and the unstable behaviour that affects the operation of fusion powered power plants.

Bricks made from coal-fired power plant waste pass safety test

Researchers have found that bricks made from fly ash--fine ash particles captured as waste by coal-fired power plants--may be even safer than predicted. Instead of leaching minute amounts of mercury as some researchers had predicted, the bricks apparently do the reverse, pulling minute amounts of the toxic metal out of ambient air.

GE Invests, Delivers One of World's Largest Solar Power Plants

Nymphadora — Thu, 12 Apr 2007 12:37:33 -0500

Spread across a hillside pasture amid olive trees, 52,000 shimmering photovoltaic modules in one of the world's largest solar power plants have begun generating enough electricity for 8,000 homes, GE, PowerLight Corp. and Catavento SA announced today.
