Scientists have found a way to use solar energy to generate electricity cheaply on a large scale, even at night. We all know the sun does not shine at night. That’s one reason solar energy is still not the best means of powering our homes and offices, although it could theoretically satisfy a substantial portion [...]
California-based Pythagoras Solar has developed a new green building material that combines energy efficiency with high density solar power generation in an aesthetically appealing package. Unlike conventional building-integrated photovoltaic products, the new glass unit simultaneously blocks solar radiation, concentrates sunlight and converts it into solar energy.

The power is yours – don’t waste it! Power up your base station with solar power and take the green path with Eltek Valere. ……………………………… Telecom operators around the world have responded to the growing climate change concerns by setting aggressive carbon emission reduction targets. With the Flatpack2 HE we set a new standard for [...]
Californians could soon be powering their homes, and no doubt their hot tubs, from a space-based solar electricity programme. The plan by the state’s massive energy company PG&E calls for the generation of 200 megawatts over 15 years to be collected by space-based solar arrays and beamed down to earth via radio frequency. PG&E hopes [...]
Solar water heaters—also called solar domestic hot water systems—can be a cost-effective way to generate hot water for your home. They can be used in any climate, and the fuel they use—sunshine—is free. ……………. How They Work Solar water heating systems include storage tanks and solar collectors. There are two types of solar water heating [...]
Researchers at Massachusetts Institute of Technology (MIT) have discovered a new way of storing energy from sunlight. The breakthrough could potentially lead to ‘unlimited’ solar power. …… The process, which is loosely based on plant photosynthesis, uses solar energy to split water into hydrogen and oxygen gases. When needed, the gases can then be re-combined [...]
A US scientist has developed a new way of powering fuel cells that could make it practical for home owners to store solar energy and produce electricity to run lights and appliances at night. Click to see:Calfinder’s Blog A new catalyst produces the oxygen and hydrogen that fuel cells use to generate electricity, while using [...]
Definition: A solar vehicle is an electric vehicle powered by solar energy obtained from solar panels on the surface of the vehicle. Photovoltaic (PV) cells convert the sun’s energy directly into electrical energy. Solar vehicles are not practical day-to-day transportation devices at present, but are primarily demonstration vehicles and engineering exercises. Some solar cars compete [...]
