Intel's solar-powered CPU prototype

Justin Rattner, Intel Chief Technical Office, today showed off a prototype CPU with such a low power rating that it can run from a solar cell the size of a postage stamp.
Code-named Claremont the Pentium-class processor is capable of operating at less than 10mW and still run operating systems such as Linux or Windows.
"It's part of our long standing obsession with power reduction," said Intel CEO, Paul Otellini when he showed a sneak peak of the setup on Tuesday.
The huge power saving has been made possible by operating the transistors in the processor at near their threshold voltage.
The threshold voltage is the voltage at which the transistor turns on.
Today's processors operate at several... »read more
