Researchers can now image the flow of energy in nuclear fusion ignition attempts

It's fair to say that nuclear fusion is the holy grail of clean energy production, with the potential to provide limitless clean energy, but right now there are a fair few barriers to making it a reality. An international team of researchers has inched the dream one step closer to reality, creating a method by which energy dispersal can be observed during ignition attempts, paving the way for improved energy delivery during the process.Read More

Researchers produce new fuel from coal dust and algae

Researchers at the Nelson Mandela Metropolitan University (NMMU) in South Africa have developed a new fuel, known as Coalgae. Made from a combination of algae and coal dust, the latter of which is a waste product, the fuel could have a significant positive impact on the environment.Read More

Powered by body heat, Lumen flashlight never needs batteries

Whether it be for everyday carry, outdoor adventure, or disaster preparation, flashlights tend to be found towards the top of must-have items. But one common aspect of these luminescent devices is that they're only as good as the batteries inside. If you've ever switched on a flashlight only to experience a flood of frustrated disappointment, you might appreciate owning an "eternal flashlight." Lumen is designed to be powered by body heat, never needing batteries.Read More

Could a hydrogen-powered iPhone be in the works?

For decades we've been promised that hydrogen fuel cells will revolutionize our lives, but it always seems to be around the next corner. But that hasn't stopped one UK company from pursuing a near future in which iPhones and other devices are completely disconnected from the electrical grid and instead use embedded fuel cells to power themselves for a full week between recharges.Read More

Hybrid road sweeper keeps air cleaner, too

A Swiss joint venture has developed a hybrid-electric powertrain for road sweepers that's said to consume half the energy of diesel-hydraulic vehicles and reduce emissions by more than 60 percent. The modular system can also be adapted to cleaner fuel types such as hydrogen. Read More

Moth eyes inspire more efficient photoelectrochemical cells

As nocturnal creatures, moths need to maximize how well they can see in the dark whilst remaining less visible to avoid predators. This ability to collect as much of the available light as possible and at the same time reflect as little as possible, has inspired Researchers at the Swiss Federal Laboratories for Materials Science and Technology (Empa) to design a new type of photoelectrochemical cell using relatively low cost materials.

Net-zero energy test home ends year-long study with surplus energy

Braving a harsh winter with snow-covered solar panels, the Net-Zero Energy Residential Test Facility (NZERTF) in Washington DC has come up trumps in a year-long study of its energy harvesting capabilities. Located on campus at the National Institute of Standards and Technology (NIST), researchers used computer simulation to replicate the energy consumption of a family of four. At the end of its first 12 months, there was a large enough surplus to power an electric car for 1,440 miles (2,317 km). Read More
