Green Products Has Located an Incredible Low Cost High Output Solar Design

At Green Products, we have come across a product from Cool Earth: Solar Balloons. Cool Earth was created with the mandate of producing electricity using solar power, specifically solar cells. Solar power is not a new concept, but how the sunlight is collected and concentrated is truly unique.

The current installed solar plants use flat-panels. Each panel is heavy, large, easily damaged, and costly to repair. This means the cost to produce a watt of electricity is 5-7 times greater than using natural gas and is not a feasible alternative to fossil fuels. This is no longer true with the Cool Earth solar balloon system.

The silver orbs are made from Mylar, with half the orb covered in a mirror-like material and the other half clear. The material is resistive to the normal outside elements and easily repaired if damaged. Near the top center is the solar cell that converts all the concentrated light to electrical energy. This is truly one of the most unique green products we have seen in the renewable energy sector.

This unique design can concentrate the sunlight so well, it produces 300 to 400 times more power per square inch of solar cells than traditional flat-panel solar systems. By regulating the air pressure inside the balloon, they can focus the concentrated sunlight directly on the photocell. The air regulating system is designed to maintain the proper balloon size as the outside air temperature increases or decreases.

Each balloon is eight feet in diameter and can withstand over 100 mile per hour winds. The balloons are linked together in series, with the initial installation able to produce 10 megawatts, enough to power 3,500 homes during the day.

This system is ideal for any of the western states where sunlight is most abundant and is not obscured by long term cloud formations during an average year. During the summer months this type of system could be used as a "peaker" (that is, a peak-use power source) to prevent rolling power outages.

Some of the more interesting aspects of this solar power station are how simple the design is and how multiples are pulled together to produce a solar power plant. Check it out.
