Production of Nanotech Solar Cells to Begin in Asia:
"Nanotechnology-based solar cells that could make solar power economically competitive with fossil fuel energy will go into production following an agreement between an American startup and an Asian giant. Japanese-headquartered Matsushita Electric Works
has agreed to apply technology developed by Nanosys
to produce solar cells for the Asian building market. While traditional silicon-based photovoltaic cells are expensive to manufacture in large quantities, Nanosys reported this April
using inorganic nanocrystal and nanocomposite technology to develop high-performing cells that are cheap to produce." From the company website: "Nanosys has raised $17 million in initial venture financing, and is funded by five leading venture capital funds: ARCH Ventures, CW Ventures, Polaris Ventures, Prospect Ventures Partners and Venrock Associates.

Ice-cream chilled with sound waves, milk cooled by the sun
:"An eco-friendly fridge freezer that uses sound to cool itself is being tested on ice-cream in the US. The new technology could eventually replace ice-cream cabinets run on ozone-damaging chlorofluorocarbons. Meanwhile, a prototype ice and solar panel tank is chilling Spanish milk with a dual cooling system to ensure the milk remains cold from dawn to dusk." 6:51:52 AM
In Praise of Petroleum
: "in an editorial appearing this week in the journal Science, [Berkeley prof. Kirk] Smith argues that switching all 2 billion of the world's poor to liquefied petroleum gas for household use would add a scant 2 percent to the global greenhouse gas emissions of fossil fuels. At the same time, using gas fuel would decrease the environmental impact on local biomass resources.. Smith led the research team analyzing the health effects of indoor smoke from solid fuels for a recent World Health Organization report. The report, published in October, found that indoor smoke from solid fuels ranked as one of the top 10 risk factors for the global burden of disease, accounting for 1.6 million premature deaths each year.
