Gallium phosphide nanowires boost hydrogen yield in prototype solar fuel cell

By - July 20, 2015 2 Pictures

One of the most promising forms of artificial photosynthesis involves using solar energy to split liquid water to produce oxygen and hydrogen gas, which can be stored and used as a clean fuel. And one of the most promising semiconductor materials for such a task is gallium phosphide (GaP), which can convert sunlight into an electrical charge and also split water. Unfortunately, the material is expensive, but researchers have now used a processed form of gallium phosphide to create a prototype solar fuel cell that not only requires 10,000 times less of the precious material, but also boosts the hydrogen yield by a factor of 10.

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.

Hydrogen-powered Hycopter quadcopter could fly for 4 hours at a time

By - May 19, 2015 3 Pictures

When people suggest possible uses for electric multicopter drones, it frequently seems like they're forgetting something – presently, most such aircraft can only fly for a maximum of around 25 minutes per battery charge. Horizon Energy Systems, however, is developing a quadcopter that should do a lot better. Known as the Hycopter, the fuel cell-powered drone is hoped to be capable of 4-hour flight times once completed.

Imperfect graphene may be perfect for use in better fuel cells

By - March 19, 2015
We already knew that graphene was a highly useful material, but just how useful is it? Well, it turns out that even defective graphene may be valuable. According to a team of mostly-American scientists, improperly-formed graphene could find use in next-generation fuel cells. Among other things, those cells might allow electric cars to be recharged in the amount of time that it currently takes to refuel a gas-burning vehicle. Read More

Urinal prototype uses fuel cells to generate steady stream of electricity

By - March 7, 2015 2 Pictures
Human urine has been turned into all sorts of things over the centuries. Alchemists distilled phosphorous from it, it was once used for the production of gunpowder, tanners employed it in great vats to tan hides, and it has served as the basis of a myriad chemical substances, including the first types of plastics. Now yet another use for this ubiquitous liquid has been created. Researchers working at the University of the West of England (UWE Bristol) have built a urinal that converts urine directly into electricity. Read More

kraftwerk aims to put a power plant in your pocket

By - January 27, 2015 5 Pictures
Battery packs like the iCruiser are handy for recharging mobile devices off-the-grid, but they soon run out of juice, which isn't ideal if you'll be away from mains power for an extended period of time. You could go solar with a device like the Waka Waka, but then there's the worry of getting enough rays. Another option may be on the way in the form of kraftwerk: a prototype fuel cell power pack for USB-powered devices that runs from gas canisters and promises to charge an iPhone up to 11 times before needing a refill.
