Da Gadgetz

Ever drive on the highway and think about how much solar energy is wasted on the asphalt below? Apparently, so has Solar Roadways. The startup was awarded a $100,000 U.S. Department of Transportation (DOT) grant this week to prototype its Solar Road Panel–an energy-generating panel made from solar cells and glass that is meant to replace petroleum-based asphalt on roads and in parking lots.The panels, designed by Solar Roadways founder Scott Brusaw, contain embedded LED lights that might eventually act as a “smart” system, providing travel lines as well as timely warnings to drivers about roadblocks and wildlife up ahead. At the same time, embedded heating elements in the panels could prevent snow and ice from building up on the road.Once a prototype is complete, Solar Roadways still has a long ways to go before its technology is commercialized. But if and when it is, Brusaw estimates that covering the entire U.S. interstate highway system with his 12′ by 12′ panels could fulfill the country’s energy needs (based on each panel producing 7.6 kilowatt hours of power each day).

Sakku has introduced the Solar Buddy for those who just need something tossed over their shoulder, and while the solar panel is unmistakable, the bag still manages to go easy on the eyes. Reportedly, the knapsacks are constructed from recycled material, and while the “direct” model charges portable gadgetry directly (big shock, right?), the “akku” model actually includes a battery pack that can be juiced for use in darkened alleyways and the like. A tad steep at €175 ($271) / €245 ($380) in order of mention, but it’s probably a design premium we’d be willing to pay.
