Can crowdfunding give us safe fusion power by 2020?

By - May 18, 2014 7 Pictures
A group of researchers at New Jersey-based LPP Fusion is turning to crowdfunding to demonstrate net power gain from a nuclear fusion reactor. The scientists plan to do this using a technique which is relatively little-known, but which they claim is scientifically sound and only relies on well-established science. Given enough funding, the researchers say they could design a US$500,000, 5 MW reactor that would produce energy for as little as 0.06 cents per kWh, all by the end of the decade. Read More

Altaeros set to break world record with 1,000 foot-high floating wind turbine

By - April 6, 2014 14 Pictures
Winds are stronger and steadier at higher altitudes, that’s why the Buoyant Air Turbine (BAT) from Altaeros is pushing to be the highest wind turbine in history. Already tested to 500 feet off the ground in 45 mph winds, this helium-filled shell with a wind turbine in the middle is soon shooting for a world record 1,000 ft float. Packing down into a shipping container for transport, the BAT is being proposed as a quickly deployable tethered power source for remote areas and emergency zones. Read More

Rainwater used to generate electricity

When we complain about the rain, other people will often say "Yeah, but it's good for the plants." Well, thanks to a microturbine-based system created by three students from the Technological University of Mexico, it's now also being used to generate electricity for use in low-income homes.

Panasonic's Power Supply Container: A solar power plant in a box

By - March 25, 2014 5 Pictures
In an effort to bring reliable electricity supplies to emerging regions and remote island communities, Panasonic has developed an expandable, portable, self-contained photovoltaic system. The "Power Supply Container" comes equipped with 12 of Panasonic's HIT240 solar modules on the roof and generates approximately 3 kW of electricity, with 24 lead-acid batteries capable of storing 17.2 kWh of energy used to store excess electricity.

Researchers develop new microengine, but aren't sure how it works

By - March 22, 2014
If you’re going to do something like building a Porsche 911 that fits on the head of a pin, or make a microscopic medical pump, you need a microscopic engine. A team of researchers from the University of Twente in the Netherlands, the Russian Academy of Sciences, and Germany’s University of Freiburg have developed a micro-engine that burns oxygen and hydrogen, but there’s a small problem; they’re not sure how the thing works.

Tungsten diselenide shows potential for ultrathin, flexible, semi-transparent solar cells

By - March 10, 2014 3 Pictures
Graphene, the two-dimensional lattice of carbon atoms, may be the wonder material du jour, but ultrathin layers of other elements are also proving to be an exciting area of research. One-atom-thick sheets of germanium and tin have shown potential as semiconductors and a topological insulators respectively, and now ultrathin layers of tungsten and selenium have been used to create a diode that could be used in ultrathin, flexible, semi-transparent solar cells.

Former Nazi bunker transformed into green energy power plant

By - February 11, 2014 13 Pictures
Energy and utilities company Hamburg Energie has joined forces with IBA Hamburg to transform a former Nazi anti-aircraft flak bunker into a green energy power plant. The Hamburg-based "Energy Bunker" has already begun producing energy for the local community, but once running at full capacity will provide up to 3,000 homes with heating, and another 1,000 homes with electricity.
