Getting something for nothing is always good, which is probably why we tend to find solar powered gadgets so appealing. This solar powered iPod speaker from Hammacher Schlemmer fits right in, giving you up to an hour of free playback time following a three hour charge. Then when your free power trip is over, you can still plug it and run it using good old fossil fuel power.
One neat feature, is that unlike that other solar iPod speaker we saw last year, this one has an IPX-4 waterproof rating so you can safely use it poolside. Just make sure you charge it up ahead of time.
The solar iPod speaker is available now for about $200.
