Computing's power problem

When it comes to computing, much of the focus is on getting more powerful computations out of ever-smaller chips (think of your cell phone) but it isn't always about intense calculations. There is a different issue: power. If we want to deploy sensors in the corners of the world or the crannies of our lives, the chips need a continuous source of stable power or the software basically breaks. Brandon Lucia at Carnegie Mellon University is trying to solve this in hopes that low-cost, low-power computer chips can be used with less risk of failure.

"This isn't about high intensity computing. It is about not having a battery," Lucia says. He is developing a programming language and computer systems to be included in the world's smallest satellite, expected to launch next year.
