Concentrating Photovoltaic Power.
By Katie Howell, Greenwire, July 6, 2009. "As the race to create clean, renewable power heats up, the solar industry is focusing on a technology in hopes of producing utility-scale energy. Concentrating photovoltaic (CPV) solar power -- which marries traditional solar photovoltaic technology to large-scale concentrated solar power plants -- could ramp up utility-scale solar production, advocates say, especially in niche markets. But as with all developing technologies, the effort faces significant hurdles. CPV technology involves magnifying the sun's energy hundreds of times via lenses or mirrors and focusing it onto small, extremely efficient photovoltaic cells. By magnifying the solar energy, the technology can reduce the amount of semiconductor material needed for the photovoltaic cell... Nancy Hartsoch, [of] SolFocus, a California company [said their design] 'uses 4 gallons of water per megawatt-hour of electricity produced -- most of that to clean the panels -- compared with about 850 gallons per megawatt-hour at a solar thermal plant.'"

Which simply proves my point. Give science time to find the right and/or the best sources of renewable energy, not politicians.
