I'm one of those wannabe Luddites who doesn't even own an iPod. I nearly scoff whenever I spy those telltale white strings dangling from ADHD-afflicted ears around town. Nor do I use any other MP3 player in public; the ambient sounds of belching engines and Super Mario Bros ring tones are street music to these ears. But if I did have an iPod Nano 1.0, I'd probably get one of these $15 recycled plastic Jimi cases. The U.S.-made, polypropylene and polycarbonate Jimis come in red, blue, clear, and orange flavors.

As kids, some people (none of us here at Crave, of course) licked batteries to experience a little jolt. Turns out that old pastime could now have a practical application--producing battery power. A Japanese inventor is developing a battery, made mainly of carbon-based compounds, that's activated by a single drop of water. Susumu Suzuki describes his device in a video interview with Reuters.
This eco-friendly energy source--which has an electric current as powerful as that of a standard manganese dioxide battery, its creator says--would be cheap to produce and could be recycled several times. Most notably, it could potentially … Read more
I was psyched when a reader said this little box can show in dollars and kilowatt-hours just how much every last lightbulb, TV, and forgotten camera charger in your house costs you. The Energy Detective, or TED, will flash an alarm when your hourly or monthly power consumption reaches painfully expensive levels, and when spells of high or low voltage might damage connected gear.
To go on a proper energy diet, first you'd have to measure the power consumed around the house, outlet by outlet. Just like counting calories, that would take all the fun out of gobbling up electricity. But if you're really geeked about saving money and greening your home, then you might follow the lead of one Silicon Valley engineer who crusaded around his apartment with the Kill-a-Watt energy meter, measuring the appetite of nearly every appliance.
Eric Boyd calculated that over a year, his refrigerator, desktop PC, and iMac used the most electricity. He estimated that his stove, … Read more
