Tiny hydrogen cars not just child's play

Automobiles have paved the way for hybrid and alternative energies in transportation, but other vehicles are quickly following their tracks. We've seen trains, golf carts and even wheelchairs running on non-fossil power sources in recent months alone. But one there's one category we hadn't anticipated: toys.

Horizon Fuel Cell Technologies first made headlines with its hydrogen-powered "H-racer" remote-controlled miniature car, which Gizmag says is the "best-selling fuel cell product in the world." Now, Horizon has developed what it calls the "H-cell" power source, which it claims allows miniature cars to reach … Read more

A wind turbine for the backyard

No, it's not some kind of futuristic crossbow, though we would certainly understand if you thought it was. This weird-looking contraption is the "Loopwing Wind Turbine," a wind-powered energy source designed for home use and scheduled for official introduction at Japan's Eco-Products 2006 Exhibition. Treehugger says the device's wing design operates with "low vibration" but notes that the specs are vague--"43 percent power performance at optimum wind speeds," whatever that means. Still, we're reasonably sure it has more guts than the recently discovered wind-operated lamp.

A lamp powered by wind, sort of

As alternative energies finally become more mainstream, wind power often remains an afterthought compared with solar and other sources. The Elica lamp, made by an Italian design firm, is taking one modest step to raise wind energy awareness among the masses.

The lamp can be turned on and off by blowing on its "helix," or propeller. Mobile Whack says an "airblow censor" can help keep the lamp from being switched on accidentally. We have only one issue with this otherwise innovative appliance: According to the Elica site, it must still be plugged into an electrical outlet--which, … Read more

Cool iPod alternative

If you are in the market for an MP3 player but want something that differentiates you from the crowd of iPod owners, may I suggest the Samsung YP-K5? This unique MP3 player has a built-in speaker as well as an FM radio. Comparing with the iPod Nanos (same capacity), the YP-K5s are a bit pricier, but it?s a small price to pay to be different. The YP-K5 comes in two versions, the 2GB for a little more than $170 and the 4GB for about $250, although Best Buy offers it for $220.

Alternative fuel tested for wheelchair

Suzuki knows that alternative fuels aren't just for cars. So the Japanese company is turning its eco-friendly eye toward a new market: wheelchairs.

Gizmag says a prototype "fuel cell wheelchair" is in the works, using methanol to generate hydrogen and then electricity. It adds that, with a range of up to 25 miles, the wheelchair would help allay fears of getting stranded.

It's good to see that alternative energy research is going toward vehicles other than golf carts.

Solar can look good even without a tan

Maybe we're just superficial (OK, probably), but we've often suspected that appearances are a key reason that solar products haven't taken off with the masses. Too often they look like something you'd find listed under "contractor's special" than, say, at Bang & Olufsen. So leave it up to the marketing-obsessed electronics business to come up with some effective packaging. Case in point: Sanyo's new Eneloop device, whose solar-powered batteries can recharge products through a USB connection while looking decent enough to display in the open. Now the marketing department just needs to … Read more
