Organic batteries are an exciting area of research at the moment due to the benefits and potential they have to power our gadgets in the future. One of the companies at the forefront of organic battery development is NEC, which has been working on these polymer-based batteries since 2001 and had its first major release in 2005.  Organic batteries are desirable because they have a very high energy density considering their size, use no heavy metals, and are incredibly thin. That last feature is highlighted by NEC’s latest breakthrough, which has seen the creation of a 0.3mm thick organic radical battery.  Such a thin battery can be placed inside objects that are already very limited in thickness, for example, a sheet of e-paper, and of course a smart card or credit card. Until now the thickness was limited to 0.7mm, but NEC managed to cut that by over 50% all thanks to printed components.  The prototype battery was created by printing an integrated circuit and battery directly on to a polymer film. Such components allowed for a complete system to be built including a display, antenna, and encryption system. All of which sounds like the perfect solution for next-generation smart cards.  As for the power on offer from this super-thin battery, output is rated as 5kW/L with a capacity of 3mAh. In real terms that means the integrated display can be refreshed 2,000x, or the antenna can be used to transmit data 35x before a recharge is required. The recharge only takes around 30 seconds to top up the battery fully, and the capacity is only reduced by 25% after 500 charges.

Positive Energy change for Japan

 What appears to be an array of metal flower petals is not an art installation but part of a cutting-edge solar-power system meant to address the critical power shortage Japan now faces in the wake of the Tohoku earthquake and tsunami on March 11, 2011.

The disaster, which triggered a crippling nuclear accident at the Fukushima Daiichi plant, reignited worldwide debate about the safety of nuclear power and forced Japan to reevaluate its energy strategy.  Of Japan's 54 nuclear reactors, 52 have been shut down for maintenance; the remaining two are set to go offline this spring. The reactors are likely to remain inoperative while Japan's central and local governments assess which (if any) of them can be restarted, leaving the country to make up for a 30-percent loss in power generation.  Rising electricity prices and limited supply threaten to hamper the recovery for manufacturers. So it makes sense that Solar Techno Park, the country's first solar-power research facility, is operated not by the government but by a unit of the Tokyo-based JFE, the world's fifth-largest steelmaker. Given the energy-intensive nature of steel production, reliable power will be key to the future of Japan's steel industry. The facility, which opened in October last year, is developing advanced technology in solar light and thermal power generation that it aims to apply both in Japan and overseas.  Located along the industrial coast of the port city of Yokohama, the Solar Techno Park aims to achieve a combined output capacity of 40 to 60 kilowatts this spring. The facility's most notable apparatus is the HyperHelios (seen here), a photovoltaic system consisting of rows of heliostats with mirrors that follow the sun and a receiving tower. Two types of solar thermal power systems are also being developed in the park.
