New solar cell is its own battery

New solar cell is its own battery

Solar power is an important part of our future, but in many ways it is still too expensive. The Ohio State University has helped lessen that issue with a new device it created -- a solar cell that serves as its own battery, doing so using a type of panel design that introduces air into the "breathing" battery.

Raspberry Pi Model B+ has more slots, less power demand

Raspberry Pi Model B+ has more slots, less power demand

The Raspberry Pi Model B is getting another facelift and no, this isn't a Raspberry Pi 2, and all that is implied by that major name change. Instead, the B+, as the name would suggest, is a very incremental improvement over the existing Model B, giving makers and hackers more connectivity options but retaining the same core and keeping compatiblity with the existing software and peripherals.

Sharp solar cells can reach 60 percent efficiency

Sharp solar cells can reach 60 percent efficiency

Solar power is perhaps the most well-known alternative source for power, but because of cost and the puzzles of physics itself, it is still quite far from becoming a completely sustainable and practical replacement. Sharp, however, may be on the breakthrough of creating solar cells that are twice as efficient as currently existing cells, at least in theory.

Cree brings energy-saving LED lights to broader market

Cree brings energy-saving LED lights to broader market

This week the folks at Cree have begun pushing their newest set of LED lightbulbs. These bulbs may look like a standard lighting fixture, but they’re working with unprecedented bits and pieces - like a Color Rendering Index number of 93. This company is not only making way for a new era of color-correctness, they’re aiming to bring the industry to a 100-percent LED awareness level as well.

KAIST Wireless Power: Charge 40 phones at one go

KAIST Wireless Power: Charge 40 phones at one go

Researches at Korea Advanced Institute of Science and Technology (KAIST) are on to something big; so big that it will change your perception about wireless charging forever. With the technology that they are on to, KAIST researches hope to make power cords redundant in the future and get you to power up to 40 smartphones at one go. The good news is that the technology can be extended to powering a large TV or even a fan.

Raindrops and toilets can potentially power your home

Raindrops and toilets can potentially power your home

Scientist from South Korea have a found a way to harness power from a flushing toilet to generate electricity. Technically the application can be extended from toilet flushes to rainwater, ocean waves, river currents, even to a drop of water. However, it sounds way cooler when we say that the mechanical energy from flowing water in your toilet bowl can potentially power your home.
