Toshiba has been promoting its green credentials with a variety of new technologies at this week's Consumer Electronics Show in Las Vegas.
Its Super Charge Battery - SCiB - is a rechargeable battery said to offer "excellent safety, long-life and rapid charging".
Prototypes of notebook PCs integrating a SCiB point the way to improved battery life said Toshiba. The SCiB can be recharged 6,000 times with a target recharge time of 90% in just 10 minutes.
The commercial application of SCiB in an electric bike is on display.
In addition, advances in cutting energy consumption in TVs are being showcased by new LCD TVs, including future models integrating a new panel that Toshiba has used to cut power consumption by 26% - equivalent to reducing CO2 emissions by 214g a day.
New EPEAT computers - the Portégé A600, Portégé R600, Portégé M750 - are also being shown. They do not contain potentially harmful cadmium, lead or mercury, and they offer energy-efficient operation, and a design for recycling and green procurement, said Toshiba.
Energy-saving light-emitting diodes (LED) are also on show. They directly convert electrical energy into optical energy. The E-CORE 100 and E-CORE 60 LED downlight series are lighting up the Toshiba booth at the show.
They have a long life of 40,000 hours, and consume only one-seventh of the power of an equivalent mini krypton bulb, said Toshiba.
