All In One Boat

“Researchers are developing a solar collector to turn roads and parking lots into cheap sources of electricity and hot water. “Asphalt has a lot of advantages as a solar collector,” says Rajib Mallick of Worcester Polytechnic Institute. “For one, blacktop stays hot and could continue to generate energy after the sun goes down, unlike traditional solar-electric cells.

Plus there’s already gynormous acreage of installed roads and parking lots. They’re resurfaced every 10 to 12 years. The solar retrofit could be built into that cycle. No need to transform other landscapes into solar farms. Or maybe not as many.

Furthermore, extracting heat from asphalt would cool the urban heat-island effect, cooling the planet a wee bit. Finally, solar collectors in roads and parking lots would be invisible, unlike those on roofs. Cuz we all know how attractive roads are.”

“A new type of solar energy collector concentrates the sun into a beam that could melt steel. Researchers say the device could revolutionize global energy production.

The prototype is a 12-foot-wide mirrored dish was made from a lightweight frame of thin, inexpensive aluminum tubing and strips of mirror. It concentrates sunlight by a factor of 1,000 to produce steam.

“This is actually the most efficient solar collector in existence,” said Doug Wood, an inventor based in Washington state who patented key parts of the dish’s design — the rights to which he has signed over to a team of students at MIT. ”

Solar Fire

“A proposed Central Valley power plant will tap three potent sources of renewable energy at once - the sun, crop stubble and cow manure.

The plant, near the old oil-patch town of Coalinga in Fresno County, will combine a large solar farm with a generator that burns orchard trimmings, agricultural waste and, yes, excrement.

Pacific Gas and Electric Co. will announce Thursday that it will buy electricity from the plant, which will be built by Martifer Renewables, a U.S. subsidiary of a Portuguese company. Terms of the deal have not been disclosed.

The plant’s design will allow it to do something not typically associated with solar power. It will keep running, and generating power, at night. ”
