 Scientists have invented a plastic solar cell that can turn the sun's power into electrical energy, even on a cloudy day.
The plastic material uses nanotechnology and contains the first solar cells able to harness the sun's invisible, infrared rays.
A hydrogen-powered car painted with the film could potentially convert enough energy into electricity to continually recharge the car's battery. ( Read More.)Labels: efficiency, electric cars, solar |

 Scientists have invented a plastic solar cell that can turn the sun's power into electrical energy, even on a cloudy day.
The plastic material uses nanotechnology and contains the first solar cells able to harness the sun's invisible, infrared rays.
The breakthrough has led theorists to predict that plastic solar cells could one day become five times more efficient than current solar cell technology. (Read More?)

The SolarBee incorporates patented near-laminar radial flow technology that provides high-flow, long-distance circulation™ (LDC) to improve water quality in freshwater lakes and reservoirs, potable water tanks and reservoirs, wastewater ponds and lagoons, and estuarine environments.
Solar-powered, the energy savings from each unit is equivalent to about 220,000 kW hrs per year, or the annual energy requirements for about 20 homes or 25 passenger cars, thereby reducing equivalent carbon dioxide emissions (the leading Greenhouse Gas, GHG) by about 150 tons per year.
We need more responsible technology like this.

 Scientists long ago calculated that an hour’s worth of the sunlight bathing the planet held far more energy than humans worldwide could use in a year, and the first practical devices for converting light to electricity were designed more than half a century ago.
Yet research on solar power and methods for storing intermittent energy has long received less spending, both in the United States and in other industrialized countries, than energy options with more political support.
Indeed, there are few major programs looking for ways to drastically reduce the cost of converting sunlight to energy and — of equal if not more importance — of efficiently storing it for when the sun is not shining.

 Solar Wind Technologies LLC configured the system using solar panels, a small wind turbine, batteries and a special lamp, all mounted to a regular light pole. With and a small wind turbine and battery backup.
“This is a great application for the city,” said Mike Correale of Solar Wind Technologies LLC. “With a solar and wind hybrid system, we can extract energy from the sun or the wind, both of which are prominent here in North Texas, generating clean, green energy.” The cost of the solar/wind power system is about $6,600 a pole, but the cost to extend utilities and the average monthly electrical cost of about $400 a pole per year is saved since the light pole doesnt use electricity. Additionally, when the power is out, the light will still be on at night. Labels: renewables, solar, wind power |

 Inventors unlocked the secrets of turning the sun's rays into mechanical power more than a century ago, only to see their dream machines collapse from lack of public support. Modern solar engineers must not be doomed to relive their fate.
Many of us assume that the nation's first serious push to develop renewable fuels was spawned while angry Americans waited in gas lines during the "energy crisis" of the 1970s.
Held hostage by the OPEC oil embargo, the country suddenly seemed receptive to warnings from scientists, environmentalists, and even a few politicians to end its over-reliance on finite coal and oil reserves or face severe economic distress and political upheaval.
