Every day is Earth Day, hard-core environmentalists will tell you, but on the calendar it's April 22. And if you want to show some support for Mother Earth, you might as well do so without abandoning your techie principles. There's no shortage of energy-efficient, ecofriendly, or generally "green" gadgets available, but here are 15 of the coolest, weirdest, and most practical, in no particular order.
Smart power strips
Some gadgets quietly draw energy even in standby mode, but who can be bothered to unplug everything or to trigger-flip the surge protector just to save a few watts? Bits Limited's Smart Strips, starting at £27, automatically shut off several devices, like Blu-ray players or game consoles, when you turn off a master device, such as a television.
Enough with the solar-powered gadgets already. The nPower Personal Energy Generator builds up charge as you move--just throw it in a bag or hold it in your hand. It's compatible with plenty of gadgets, including iPhones and BlackBerry handsets. The maker, Tremont Electric, is taking preorders now.
