Solar powered lighting for your deck or backyard is pretty popular these days, but here’s another eco-friendly solution to illuminate your next BBQ. While the Firewinder looks like the kind of kitschy outdoor wind chime you’d find at an arts & crafts sale, the spinning motion of its upward spiraling helix is actually used to power a generator which in turn illuminates a set of 14 ultra bright LEDs. The helix design allows the Firewinder to harness the wind no matter what direction it’s blowing, and it features an ultra-light design so even the lightest breeze will keep it going. The LEDs are also located along the edge of the helix which produces a unique lighting effect as it spins. …read full discussion

ReUSaBle Batteries

ReUSaBle BatteriesWe want some! We still adore oureneloop batteries that we haven’t had to charge in months, even though we use them almost daily, but we really admire the ingenuity of the ReUSaBle Batteries. When their juice starts to drain, simply plug them into any USB port or 250mA Ni-MH charger. An LED will let you know the status of the charge. A pair of the 2 x AA size batteries (1.2V at 1450mAh) will cost you $19.15, well worth the amount considering that they will eventually save you money and the planet.
