Balloon technology could cut cost of solar energy 90% by 2010

2007-02-21T14:30:39Z

With high energy prices and mounting concerns over human-induced climate change, there is intense interest in renewable energy, especially solar, which produces no pollution and is readily available in the form of sunlight. In recent years, however, the solar energy market has been hampered by supply shortages of refined silicon, the critical resource needed for solar cell fabrication. Further, because solar installations traditionally require a large surface area to capture as much sunlight as possible, solar arrays often take up real estate, occupying land used agricultural production and other purposes. Without government subsidies, solar is not presently viable in many areas.

Venture Capitalists, China and Green Technology

2006-05-24T15:19:39Z
