Water Powered Clock

September 14th, 2011

What could be greener than just using a little tap water to power your alarm clock? This cool clock makes its own electricity from its electrolytic cells and the water electrons. One refill should power the clock for about 12 weeks, then all you need to do is fill it up again. It will remember the time so you don’t need to re-set it after each refill. The ergonomic design looks modern and svelte – it’s bigger than it looks in the picture though, at 6 ½ “ high. There is a choice of blue or gray. And you’ll have one less gadget to reset after a power outage too!

September 10th, 2011

This is a well designed solar charger that has had good reviews for its performance overall. It has useful suction pads so it can be fixed to the window in a bus or car and charge in the sun as you travel. For long trips the internal battery can be charged before you leave from a USB cable and then kept topped up by solar charging fairly efficiently. It isn’t designed to reach a full charge solely from solar charging, but certainly gets enough charge to power ipods and other devices. It has LED lights to indicate the remaining power level. An additional feature is its LED flash light / reading light. Altogether this is a slim design that is perfect for traveling.

Garden Hose Filter For The Organic Garden

September 6th, 2011

Organic gardeners in towns often struggle with the tap water supply they rely on for watering their gardens. Unless you have huge rain barrels to collect enough water for watering your whole garden, you have to use tap water, which is almost always chlorinated. The chlorine is designed to kill all bacteria and, as organic gardeners know, good bacteria are essential to keep the balance of the soil in good shape.
This garden hose filter removes almost all the chlorine and water soluble metals from the tap water making it easier to grow healthy fruits and vegetables organically. One filter lasts for 25,000 gallons of water, after which you can fit a refill and just keep on watering with clean pure water.
Water filter costs $35.95 from Garden.com
