Researchers at Australia's CSIRO have claimed a world record for the highest temperatures ever achieved using solar energy to generate "supercritical" steam at its solar thermal test plant in Newcastle, Australia. Featuring more than 600 directional mirrors (heliostats) directed at two towers housing solar receivers and turbines, the researchers produced the steam at a pressure of 23.5 MPa (3400 psi) and 570° C (1,058° F).  Read More

Flexible, inexpensive, large-area, lightweight solar cells are difficult to produce as they require an inert atmosphere and high temperatures, and they often degrade in a short time after exposure to air. Researchers at MIT, however, have used a new method to craft solar cells from ultra-thin layers of quantum dots in a process that promises to avoid these problems, and at room temperature. At the same time, they have also set a new record of nine percent for the most efficient quantum-dot solar cells produced to date.  Read More

The Power Pallet is a combination gasification unit and electrical generator

It could be the most important portable power plant you've never heard of. It's called the "Power Pallet" and it is essentially a combined biomass refinery and generator that fits on a single pallet and can kick out up to 20 kilowatts of electricity.  Read More

Structural supercapacitors could allow energy to be stored directly in structural material...

Imagine using a mobile phone powered entirely by its casing, or an electric car that runs off power stored in its chassis. Researchers at Vanderbilt University have created a structural supercapacitor that could, they believe, bring this closer to reality, making batteries and power cords obsolete. The structural supercapacitor could make it possible to store energy directly in structural materials, allowing them to deliver power long-term while surviving the real-life mechanical stresses they're bound to experience.  Read More

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

The Buoyant Air Turbine, from Altaeros Energies

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

The three young inventors of the Pluvia system, which uses rainwater runoff to generate el...

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.  Read More

Panasonic's Power Supply Container is a self-contained solar power plant designed for deve...

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.  Read More

At the microscopic level, combustion can't support itself, as it does in this Petri dish f...

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.  Read More

The unobtrusive nature of SnapRays adds weight to its creator's claim as a convenient repl...

Placing guidelights up your hallway or down your staircase can involve bulky plugin solutions or a professional and expensive installation. SnapRays Guidelight, an easy-install outlet cover with built-in LEDs, could simplify this process by turning any standard power outlet into a night light without the need for re-wiring or batteries.  Read More
