Here at the Giz, we want solar everything, but wish those dang arrays were more powerful. Here's another item to add to our list, and these might be just powerful enough: solar-powered driveway markers that make your personal thoroughfares look like O'Hare on a slow night.

They're tough, made of aluminum alloy that's strong enough to be run over by a truck and keep on shining. Set their LEDs to shine steady or blink, and they'll run eight hours after a day in the sun. They're $89.95 for four. Light 'em up.
