Sanyo has developed the 'N-WR01S' a non contact charger for the Wiimote which makes charging as easy as placing the Wiimote on a cradle. Scheduled to hit stores in Japan by August it consists of a rechargeable battery pack that replaces the batteries and battery compartment cover on an existing Wii remote control, and a charging cradle and AC adapter. Coils of wire in the battery pack and charging cradle transfer electricity when bought in contact. The charger completely charges the Wiimote in under four hours and makes it good for six and a half hours of gameplay.

The Sanyo N-WR01S will go on sale in Japan by August 25 with the basic set costing 5500 Yen ($ 51) and additional cradles and battery packs costing around 2500 Yen ($ 22). A very expensive proposal I would rather get 8 rechargeable alkalines and a charger for 30 bucks.
