| Florida Takes Giant Step with Huge Solar-power Plant |
The population continues to grow requiring more and more energy. We are running out of natural resources now trying to find more efficient ways to power the world. “Going Green” has been the new trend and every day we our discovering new ways to save on energy and make our world more efficient.

Orlando Sentinal published a great article about the huge step we are taking in building a giant solar-plant. Florida Power & Light Co.'s newest solar-energy plant will have enough mirrors to cover 80 football fields. But those mirrors will focus sunlight onto surfaces that add up to slightly less than the area of a single football field.

That concentration of solar power will generate temperatures of more than 700 degrees — hot enough to make electricity for 11,000 homes.

The Martin Next Generation Solar Energy Center here will rank as the world's second-largest solar plant when it begins pumping out as many as 75 megawatts of electricity late this year. It will also be the only system of its kind in the world.

Conventional wisdom holds that solar plants using mirrors — which generate heat that produces steam that, in turn, spins an electrical generator — aren't worth the effort in Florida because of the regularity of afternoon rain clouds much of the year. So far, all of the solar plants built in the state convert sunlight directly into electricity using photovoltaic panels, which produce a charge, if only a reduced one, even on cloudy days,

One thing utility engineers hope to solve once the Martin County plant is operating is the problem posed by partly cloudy days, when some of the plant's mirrors will be reflecting full sunlight but others will be shaded. Plant engineers don't want alternating pulses of cooler and hotter steam arriving at an electrical generator that runs most efficiently, and with the least wear and tear, when operating conditions are kept constant.
