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

Fracking is a highly controversial and divisive issue. Proponents argue that it could be the biggest energy boom since the Arabian oil fields were opened almost 80 years ago, but this comes at a serious cost to the environment. Among the detrimental effects of the process is that the waste water it produces is over five times saltier than seawater, which is, to put it mildly, not good. A research team led by MIT that has found an economical way of removing salt from fracking waste water that promises to not only reduce pollution, but conserve water as well.  Read More

As the Internet of Things starts to take hold, we're seeing the emergence of gadgets equipped with all kinds of sensors to improve the world around us, from energy-saving climate control systems to smart locks for the front door. But have you ever thought about how sound might be measured and used to bring another level of automation? For the last two years, the Ear-IT project has been monitoring acoustics in the Spanish city of Santander, and says the results could improve the lives of its residents in ways ranging from improved traffic flow to energy savings in the home.  Read More

Lockheed sees its compact fusion reactor as ready in 10 years

Fusion reactors are a bit like buses; you wait forever for one, then two come along at once. No sooner does the University of Washington announce that it’s working on a breakthrough compact fusion reactor (CFR) than Lockheed Martin says that its Revolutionary Technology Programs unit, AKA the Skunk Works, in Palmdale, California has one that could be ready for market within ten years.  Read More

The prototype device utilizes paraffin contained within thin aluminum plates

Although solar panels are active while the sun is shining, they typically don't do much once the sun goes down. This is why some systems incorporate water tanks. The water is heated during the day via the panels, then that stored thermal energy (heat) is used to warm the home at night. While the tanks are effective, they also take up a lot of space, making them difficult to fit into peoples' homes. A newly-developed device, however, stores just as much heat in half the space – using paraffin instead of water.  Read More

In the 21st century, the world lives with two futures ahead of it – one of looming energy shortages, and another of godlike energy abundance. The key to this whether it’s possible to turn fusion reactor technology from a laboratory exercise into a real-world application. Engineers that the University of Washington are working on a fusion reactor that, when scaled up, could produce energy on a practical scale, yet at a cost rivaling that of a conventional coal-powered plant.  Read More

Ampy is also pocketable at 3 inches square

Kinetic chargers have been around for a few years, but have typically been big and bulky. Ampy is much smaller and fashionable enough to wear around.  Read More

By playing around with materials, researchers have reduced the operating temperature of an...

Our ability to store energy has proven a big hurdle in the adoption of renewable energies. But now a team of researchers from MIT has developed a new all-liquid battery system that extends the life of such devices while also costing less to make, a development they say could make wind and solar energy more competitive with traditional sources of power.  Read More

In a development that could bring new meaning to the term "motor mouth," Canadian researchers have developed a chin strap capable of generating electricity from jaw movements. The team is hopeful that the strap will be able to harvest energy from common actions like eating, chewing and talking to power medical implants and wearable devices.  Read More

A new nuclear-powered, water-based battery may one day be used as a dependable power suppl...

Researchers working at the University of Missouri (MU) claim to have produced a prototype of a nuclear-powered, water-based battery that is said to be both longer lasting and more efficient than current battery technologies and may eventually be used as a dependable power supply in vehicles, spacecraft, and other applications where longevity, reliability, and efficiency are paramount.  Read More
