Motorola Aims to Drive Consumer Electronics

Motorola reports progress in developing alternative energy sources for consumer electronic devices -- including a wind-up power source for its cellular phones.

Motorola also says its scientists are developing miniature fuel cells for use in a range of devices that could include automobiles, cell phones, laptop computers, and digital cameras.

An experimental prototype measures 5 x 10 x 1 cm (2 x 4 x 0.4 in.) and produces more than 100 mW net power continuously, and has operated for more than a week at a time in the lab with little degradation in performance, Motorola says.

According to a Motorola spokesperson, the cell-phone wind-up energy source could be released in 2001, but a consumer electronics fuel cell is at least two years away. Researchers say work remains in designing components of the fuel cell device, developing ways to package and supply the fuel, and establishing standards and regulations for the technology.
