Nissan developing colour changing paint

Nissan is developing a paramagnetic iron oxide paint polymer. Usingan electrical charge, the arrangement of iron oxide crystals can betweaked, adjusting the car's colour. (It just so happens thatmetal-bodied cars make for excellent conductive surfaces.) But we'rereally excited over Nissan's surely bogus but juicy claim to have thetechnology on the market extremely soon, by 2010 if possible.Oh...except there's one catch.

A small amountof current is always needed to maintain the arrangement of iron oxide(your custom car colour). So when you leave your car parked/off, the carturns white.
