I long for this:

Scavenging Ambient Electromagnetic Energy to Power Small Electronic Devices

Does the rate of battery use turn you off certain mobile electronics? Not really.

Do you have a preference for rechargeables over alkaline batteries, or do you long for the day when every device can be recharged via USB? I prefer rechargeable, but dislike the price.

Or is this a non-issue, and you don't care if your excellent device goes through batteries like a champion at a pie eating contest? I'd prefer to be the one eating pie....especially blueberry or mincemeat.

What is most important to you in a battery:

• Up-front cost? Yes, I wouldn't mind so much if the useful life was longer
• Ease of recharging? Yes
• Long shelf life? Yes, what's the point of buying a bunch on sale in anticipation of my kids future toys only to find out they are no good a few years from now.
• Easy disposal? Sure, why not? Or better yet, how about a battery that doesn't need to be disposed of? When you no longer need it, turn it in so someone else can use it.
• Something else? none that come to mind.
