Nokia plans to develop a charging system for cell phones that will draw power from radio waves in the air. Check out this article, that describes on going research into the possibility of using the air as a power source. Hopefully, they will give some small credit to Ayn Rand for this! In her novel Atlas Shrugged she describes a machine that uses a very similar system to generate electricity. Of course, her point was completely different. It's just interesting that many people were critical of the novel because of her inclusion of 'impossible technology' to prove a philisophical point. Now, the impossible may be possible!

Also, take a look at some of the other cool stuff they're working on at the Nokia Research Center.
