TOKYO (Nikkei)--Toshiba Corp. (6502) said Monday that it has developed a
thermoelectric device with triple the normal capacity to convert heat into
electricity.
Thermoelectric devices generate electricity in the presence of a temperature
differential, and the greater the difference between their two sides, the more
electricity they can generate.
Most thermoelectric devices can withstand temperatures as high as 300 C.
Toshiba's new device is designed for temperatures up to 500 C, giving it
triple the capacity to generate electricity. When one side is heated to 500 C
and the other side is cooled to 20 C, the device can generate more than 1 watt
per sq. cm.
Toshiba has built a device that measures 3.7 x 3.9cm and can generate 15
watts. The idea is to attach dozens to the exhaust pipes of vehicles and
factories in order to make use of waste heat for the generation of
electricity.
The company will ship samples in July and plans to begin volume production in
fiscal 2005. The goal is to keep the price down to around 700,000 yen per
kilowatt.
