Has anyone heard anything about "wireless energy" which basically ends the need for power cords? I saw an article about it months ago, but I haven't seen anything since.

This is a rather interesting topic indeed. Have a search for a guy named Nicola Tesla. He did a lot of pioneering work in this field in the 19th century. Some of his inventions were dismissed because it would be nearly impossible to monitor individual usage or patrons, and that it posed many possibly health and safety issues.

A new company, Powercast introduced wireless power transfer technology using RF energy at the 2007 Consumer Electronics Show, winning best Emerging Technology. The Powercast system is applicable for a number of devices with low power requirements. This could include LEDs, computer peripherals, wireless sensors, and medical implants. Currently, it achieves a maximum output of 6 volts for a little over one meter. It is expected for arrival late 2007 http://www.powercastco.com/

Inductive coupling is the wireless transfer of energy. I use equipment in automotive testing that uses it. The GM EV1 electric car charged it's battery using Inductive coupling. There have been prototype systems that charged laptops, cellphones and any other portable electronics usin this idea. How cool would it be to just sit you phone, MP3, computer, and PDA on your dresser and have it charge. No chargers, just a thin rubber pad. The system has been shown but needs to be standardized to make it to production. This can be made to work over longer distances but I would be worried about the side effects.
