PowerCube pop-up solar generator provides relief to disaster-struck areas

It was seven years ago that Ecosphere Technologies revealed its first iteration of a self-contained relief unit to provide power, water and shelter to disaster-struck areas. The company has since been busy refining the system's form and function and now announces the completion of what it says to be the world's largest deployable solar power generator. Capable of generating 15 kW of electricity, PowerCube is transported as a standard shipping container and can morph into a shelter, water treatment plant and communications base all with a push of a button.

New water-based organic battery is cheap, rechargeable and eco-friendly

Lithium-ion batteries have made portable, rechargeable electronics commonplace. Unfortunately, they do have some glaring drawbacks, including heat issues, being made with rare, toxic elements, and the fact the technology doesn't scale up very well, which limits applications. A team of scientists at the University of Southern California (USC) is working on an alternative in the form of a water-based organic battery that is not only cheaper and more environmentally friendly, but also holds the potential for scaling up for use in wind and solar power plants as a means to store large amounts of energy.

Researchers create flexible wires that could double as batteries

We literally live in a wired world, with wires snaking hither and yon transmitting electricity and data. Many are visible, while many more are hidden in the walls of buildings, the panels of cars, and the fuselage of aircraft. Now, imagine; what if we were able to turn each and every one of these into a battery that not only transmitted electricity but stored it too? Well, two researchers from the University of Central Florida (UCF) imagined that too, and came up with a way to use nano-technology to make wires with supercapacitance that may eventually also double as batteries.

Fraunhofer developing fuel cell system to power the home

As the world shifts to alternative forms of energy, ways to make homes less dependent on the grid continue to gather steam. Fuel cells, which are more efficient and have lower emissions than internal combustion engines seem like a logical candidate for taking up the slack, so the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) in Dresden is partnering with the heater manufacturer Vaillant to develop a domestic fuel cell system that uses natural gas to produce both heating and electricity.

CSIRO sets world record in generating "supercritical" steam using solar power

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).

New record efficiency for quantum-dot photovoltaics

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

Structural supercapacitors could make batteries and power cords obsolete

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.
