Maxwell Ultracapacitors to Capture Subway Braking Power

The South Korean government is testing Maxwell Technologies' ultracapacitors for subway regenerative braking systems.

Maxwell Technologies' ultracapacitors are hitting the brakes on South Korean subways - a test of the technology's promise to outperform batteries in capturing and discharging electricity.

The San Diego-based company announced late Wednesday that its ultracapacitors would be used in a regenerative braking project being done by the Korean Railroad Research Institute in a Korean subway system.

Capacitors store energy as an electrical field, rather than chemically as batteries do. That means they can charge and discharge faster, and over more life cycles, than batteries, at the expense of "energy density," or amount of power stored per unit of weight. Ultracapacitors promise to solve that problem through improved energy density, using a variety of methods.

Pelamis Wave Power

Pelamis Wave Power Ltd is the manufacturer of a unique system to generate renewable electricity from ocean waves. Its first wave farm, located off the coast of Portugal, was opened in September of 2008.

clipped from en.wikipedia.org Pelamis Wave Energy Converter The Pelamis Wave Energy Converter is a technology that uses the motion of ocean surface waves to create electricity. The machine is made up of connected sections which flex and bend as waves pass, it is this motion which is used to generate electricity. Developed by the Scottish company Pelamis Wave Power (formally Ocean Power Delivery), it was the world’s first commercial scale machine to generate electricity into the grid from offshore wave energy and the first to be used in commercial wave farm project.[1] The first full scale prototype was successfully installed and generated electricity to the UK grid at the European Marine Energy Centre in Orkney, Scotland in August 2004.[2] The first wave farm, located off the coast of Portugal, was officially opened in September of 2008.[3] clipped from www.worldculturepictorial.com Pelamis in Portugal - world’s first, most ambitious, working wave farm, now generating electricity for 1,500 homes clipped from www.pelamiswave.com Pelamis Wave Power clipped from www.youtube.com

Unlike conventional solar cells, the materials being developed at Swansea are more efficient at capturing low light radiation, meaning that they are better suited to the British climate.
