Not only is this a Solar Powered Toothbrush (gawk!), but it is soapless too. Colgate executives, start packing your bags. $45.00.

‘Solar power sends charges to Titanium Oxide to send minus ion to your mouth. Cleans and sanitize without any tooth paste forever.’

You have a mobile phone (cell phone to you transatlantic-ians!) and you’re worried about the battery life? Then invest in one of these spiffy Sunpower Systems solar powered batteries. Clip ’em onto your Nokia, Samsung or Motorola handset and let the sunlight of London in December keep your phone trickle charged as you go. Or not.

They don’t cost that much more than standard batteries, but you have to wince a little at the design I reckon.
