Silent, tree-shaped wind turbines to debut in Paris

Silent, tree-shaped wind turbines to debut in Paris

Wind-generated power has the potential to make a huge contribution to varying renewable energies around the globe, but the issue of where turbines are built can be a big issue for some communities, or even countries. When wind turbines can't be built off-shore, some places feel constructing them on land ruins the scenery of the landscape, takes up too much space, or generates too much noise. Enter France's NewWind, which has been developing aesthetically pleasing, tree-shaped turbines meant to run silently within cities, at ground level.

Ocean current energy system in the works by Toshiba and IHI

Ocean current energy system in the works by Toshiba and IHI

The teams as IHI Corporation and Toshiba Corporation have begun work on an ocean energy power generation system. They've been selected by Japan's New Energy and Industrial Technology Development Organization (NEDO) as co-researchers in their new system for "Research and Development ("R&D") of Ocean Energy Technology - Demonstration Research of Ocean Energy Power Generation". The team have been working on research and development since 2011 on a Next-Generation Ocean Energy Power Generation (Underwater Floating Type Ocean Current Turbine System) - demonstration research is coming up next.

Brio smart outlet only turns on when you need it

Brio smart outlet only turns on when you need it

Electrical outlets pose different sorts of threats, most notably being to small children who poke objects inside them out of curiosity. The go-to method for avoiding this unfortunate scenario is using plastic outlet plugs that block the ports, but that's not always effective. A California company called Brio has addressed this issue with a smart outlet likewise called "Brio" that only goes live when a valid object is plugged into it. In doing so, the company hopes to mitigate the typical hazards associated with outlets.

Germany’s Sunfire makes synthetic gasoline from water, CO2

Germany’s Sunfire makes synthetic gasoline from water, CO2

While vehicles like Toyota's fuel-cell powered Mirai are leading the charge to a future less reliant on fossil fuels, Germany's Sunfire GmbH may have a way to bridge the gap with its method of producing synthetic fuel from water and carbon dioxide. By using two of the world's most abundant elements to create hydrocarbon fuel, a much great efficiency over fossil fuels can be achieved.

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.
