The End of Batteries?
Researchers in Britain have developed tiny little internal combustion engines that can be used to power PDAs, cell phones and laptops.

You can read about it at several sites, including here, here, and at http://www.research-tv.com/nano_story_template.html#. (The first two addresses are way to long and messy to post.)
