The Desolenator produces clean drinking water using sunlight

Desalination may one day prove the savior for regions of the world where clean drinking water is scarce, but current technology dictates that this process is often expensive and energy-intensive. The team behind the Desolenator has high hopes of delivering water security to those in need, with a mobile desalinator that runs purely on energy from the sun.  Read More

The SprayLD system developed by University of Toronto researchers can spray colloidal quan...

Spray-on cells hold considerable promise for reducing the manufacturing costs of solar power. Within this field, colloidal quantum dots (CQD) have also been the focus of a number if research efforts, as they have the potential to soak up a wider range of the solar spectrum. Scientists at the University of Toronto have been aboard the quantum dot train for some time now and their latest breakthrough involves a new method for spraying solar cells onto flexible surfaces, a development that could one day see them coat anything from bicycle helmets to outdoor furniture.  Read More

One of the existing Tulip pilot plants

For five years now, a Tulip concentrating solar power plant has been operating at a kibbutz in Israel. In January 2012, a second one sprouted in Spain. While both plants have been successfully pumping out electricity ever since, they were also both built as research and development exercises. Soon, however, the world's first commercial Tulip plant will be built for a paying client, in Ethiopia.  Read More

Researchers at the Australian National University are one step closer to creating an artificial photosynthesis system after replicating one of its crucial steps. The development may lead to an abundant source of hydrogen, a cheap and clean fuel that could replace all petroleum products.  Read More

The first Hello Hub has been installed in Suleja, Nigeria (Photo: Tom Saater)

In many parts of Africa, a lack of adequate infrastructure means that it's simply not practical to build a school and employ a teacher to give kids an education – but there are alternatives. The Hello Hub is a solar-powered kiosk that features two touchscreen computers loaded with educational software and an internet connection to help kids and adults learn and get online. The first Hello Hub kiosk was recently installed in Nigeria, and there are more planned for next year.  Read More

The Legson Kayira Community Center and Primary School was completed earlier this year (Pho...

Shipping container-based buildings can suffer – indeed, usually do suffer – from significant insulation issues. But Johannesburg-based firm Architecture for a change (A4AC) recently built a community center and school in Malawi from shipping containers that aims to mitigate this with an open design. The firm also installed rainwater harvesting and solar power to allow the school to operate off-grid.  Read More

The world's first solar bike path is set to open in the Netherlands next Wednesday. The SolaRoad will run through Amsterdam's northern suburb of Krommenie and will feature concrete slabs embedded with solar panels to convert energy from the sun into electricity for the grid.  Read More

A new coating material developed by UCSD researchers could help make concentrated solar po...

The key factor when it comes to solar power plant efficiency – be they of the photovoltaic or concentrated solar power variety – is the amount of light that can be captured by the light-absorbing material and converted into electricity or heat. Researchers at the University of California, San Diego have developed a new nanoparticle-based material that promises to improve the efficiency of CSP plants with its ability to absorb and convert over 90 percent of the sunlight it captures into heat.  Read More

The white solar panel provides architects with more flexibility in using solar power syste...

Solar panels are seen as a way of making buildings greener and more sustainable, as well as making them less dependent on the grid for power. The problem is that the blue/black panels stick out like sore thumbs and end up exiled to rooftops. With the goal of making solar panels aesthetically invisible, the Swiss private, nonprofit technology company CSEM has developed what it bills as the world's first white solar modules – designed to blend into buildings instead of sitting on the roof.  Read More

Aerial Power's SolarBrush aimed at reducing the maintenance costs of a solar field by 70 p...

To maintain their effectiveness, solar panels need to be kept clean, but this can be a labor-intensive and costly process. Aerial Power is the latest to seek an automated solution – the London-based startup is developing brush-carrying drones that skim along the solar arrays and wipe their surfaces clean.  Read More
