Wireless power. You can see wireless power at work in your electric toothbrush and with other devices that use short-range magnetics to recharge devices, but what about a municiple system or private company who can recharge your cell phone just by walking down the street, or buying your coffee? The laptop that need only to sit on the table at a wireless power ready cafe to stay charged, or the PDA that charges during your flight? Any battery is useless once it’s drained.
