Solar Power

Combining the high efficiency and low cost of perovskite with the simplicity of spray-on c...

Researchers at the University of Sheffield in the UK have created a spray-on solar cell that uses perovskite as the light-absorbing layer. Although the cell's efficiency is only a modest 11 percent, it can be manufactured very cheaply, paving the way for significant reductions in the cost of large-scale solar panel production.  Read More

Generating renewable electricity at home or commercial buildings is becoming increasingly viable. WindStream Technologies has installed what it says is the world's largest wind-solar hybrid array on an office roof in Kingston, Jamaica. The array is expected to generate over 106,000 kWh annually.  Read More

Rising atmospheric CO2 levels can generally be tackled in three ways: developing alternative energy sources with lower emissions; carbon capture and storage (CCS); and capturing carbon and repurposing it. Researchers at Princeton University are claiming to have developed a technique that ticks two of these three boxes by using solar power to convert CO2 into formic acid.  Read More

It was seven years ago that Ecosphere Technologies revealed its first iteration of a self-contained relief unit to provide power, water and shelter to disaster-struck areas. The company has since been busy refining the system's form and function and now announces the completion of what it says to be the world's largest deployable solar power generator. Capable of generating 15 kW of electricity, PowerCube is transported as a standard shipping container and can morph into a shelter, water treatment plant and communications base all with a push of a button.  Read More

A  large, distributed network of concentrated solar power plants in desert regions could r...

Researchers at the International Institute for Applied Systems Analysis (IIASA) have conducted a study to examine the potential for solar power to provide reliable electricity around the clock, every day of the year. The team found that a large, distributed network of concentrated solar power (CSP) plants in the Mediterranean basin or the Kalahari desert in southern Africa would be able to consistently run at 80 percent of maximum capacity or more throughout the year regardless of time of day, season, or weather conditions.  Read More

The Bio Cooler in sun-baked Aipir, Colombia

In the town of Aipir, Colombia, the temperature can often get as high as 45ºC (113ºF), yet few of the residents have a reliable source of electricity. So, pulling an ice-cold beverage out of the fridge isn't really an option. Coca Cola and the Leo Burnett Colombia advertising agency therefore devised a "Bio Cooler" for the town – it reportedly chills cans of Coke, without using electricity.  Read More

Researchers at Australia's CSIRO have claimed a world record for the highest temperatures ever achieved using solar energy to generate "supercritical" steam at its solar thermal test plant in Newcastle, Australia. Featuring more than 600 directional mirrors (heliostats) directed at two towers housing solar receivers and turbines, the researchers produced the steam at a pressure of 23.5 MPa (3400 psi) and 570° C (1,058° F).  Read More

BMW Group DesignworksUSA has designed a solar carport to house its new i3 and forthcoming i8 electric vehicles. BMW is revealing the one-car solar garage concept as part of the official media launch of the i8 in Los Angeles.  Read More

The solar reactor that was used to turn water and CO2 into jet fuel

In a move that could help address our insatiable thirst for fuel while at the same time help cut CO2 emissions, scientists with the SOLAR-JET (Solar chemical reactor demonstration and Optimization for Long-term Availability of Renewable Jet fuel) project have recently shown that through a multi-step process, concentrated sunlight can be used to convert carbon dioxide into kerosene, which can then be used as jet fuel.  Read More
