Capacitors help energy storage for security and military equipment and transportation

February 7 '08: The Economist has reported on new capacitor technology which can allow security and military personnel to store more energy for longer amounts of time without the use of conventional batteries. The new technology has also been demonstrated in cars giving one prototype 150 mph fuel efficiency.
Concerning cars, the Economist reported AFS Trinity based in Washington state has developed the XH-150, a "three-way hybrid" which boasts a 150 mph fuel efficiency. The car's capacitors work with the battery and a standard combustible engine, give the car a boost when accelerating, while the batteries charge when the car breaks.Using similar technology to transfer the current in the capacitors, the Economist reported that Texas-based company EEstor has developed a capacitor which can store "very high" levels of energy. The company said the technology was based on a barium titanate insulator. That technology will be used following a deal EEstor made with Lockheed Martin, a press release announced. According to the Economist, "EEstor ... envisages employing its devices to build an 'energy bank' to store off-peak power and release it when demand is high. One use of such a bank, the firm suggests, could be the rapid charging of electric cars - which would, of course, also be fitted with capacitors" possibly similar to the type AFS Trinity has employed in their prototype (NB - the two companies are not working together to the author's knowledge.) In the press release, Lockheed Martin said EEstor's technology "will be a fully 'green' technology" and could "provide 10 times the energy density of lead acid batteries at 1/10th the weight and volume." Lockheed Martin said it is currently looking into homeland security and military applications for the new technology.
