This futuristic gizmo developed by a California teen in her spare time could revolutionize cellphone technology.
The Voto uses a rugged and inexpensive fuel cell to charge a battery, cell phone, or power a light.
Some 900 miles to the north, Bill Gates and another Microsoft veteran, Nathan Myhrvold, have poured millions into a company developing a fission reactor that could run on today’s nuclear waste. And on the far side of the world, China has seized on discarded American research to pursue a safer reactor based on an abundant element called thorium. Beyond the question of whether they will work, these ambitious schemes pose a larger issue: How much faith should we, as a society, put in the idea of a big technological fix to save the world from ?

An important trend in electronics involves the development of materials, mechanical designs and manufacturing strategies that enable the use of unconventional substrates, such as polymer films, metal foils, paper sheets or rubber slabs.
(Phys.org)—This month, Panasonic and Tokyo Gas announced the launch of their newest Ene-Farm home fuel cell, a product that residents can use to generate energy right from their homes. This is a smaller, cheaper, and efficient successor to the Ene-Farm products of the past; the new product can operate 20 percent longer than the previous model, for 60,000 hours. The developers, Tokyo Gas and Panasonic, said that this Ene-Farm home fuel cell achieves overall efficiency of 95 percent LHV, as the world's most efficient fuel cell.

Brookhaven physicists Weidong Si (left) and Qiang Li look into the vacuum chamber where the new high-field iron-based superconductors are made through a process called pulsed-laser deposition.
There is huge potential in solar power.
Scientists at California's Stanford University have managed to construct the first solar cell made entirely of carbon.
In May 2011, uncollected rubbish piled up in Naples, Italy.
Platinum works well as a catalyst in hydrogen fuel cells, but it has at least two drawbacks: It is expensive, and it degrades over time. Brown chemists have engineered a cheaper and more durable catalyst using graphene, cobalt, and cobalt-oxide — the best nonplatinum catalyst yet.
Good news, denizens of Earth: If the findings from two premier research labs are to be believed, commercial nuclear fusion is feasible — and could arrive sooner than expected. The first breakthrough comes from Sandia National Laboratories (the same engineers who brought us the fanless heatsink ).
Cambridge, Mass. – Imagine a kerosene lamp that continued to shine after the fuel was spent, or an electric stove that could remain hot during a power outage. Materials scientists at Harvard have demonstrated an equivalent feat in clean energy generation with a solid-oxide fuel cell (SOFC) that converts hydrogen into electricity but can also store electrochemical energy like a battery.
Individual homes and entire neighborhoods could be powered with a new, small-scale solid oxide fuel cell system that achieves up to 57 percent efficiency, significantly higher than the 30 to 50 percent efficiencies previously reported for other solid oxide fuel cell systems of its size, according to a study published in this month's issue of Journal of Power Sources.
