Hand operated purifier lets you crank out clean drinkable waterIt can be tough to find clean water in many remote places, so having a quick and easy way to purify it is essential. Traditional charcoal filters can be slow, so the SteriPEN Sidewinder uses UV light to kill off any critters.
Large plug-in water purifiers that use UV light have around for years, but in remote areas it can be difficult to find a reliable source of power. With the Sidewinder, you simply fill up the 1-Liter bottle, attach the cranking mechanism, and crank until the green LED lights up.
The SteriPEN Sidewinder is expected to hit the market next month for around $100

The Pedal-A-Watt Stationary Bike Power GeneratorThe Pedal-A-Watt bicycle stand keeps the user fit while creating power that may be used to power lights and/or other small appliances.
Any bicycle that is in good shape will work with the Pedal-a-Watt Stand as the stand adjusts to fit any wheel size including children's bikes..
The average rider will produce between 125 and 300 watts using the Pedal-a-Watt. While this may not seem like much power, many pieces of equipment draw very little power and can be powered for long spans of time with small amounts of power. For example, a laptop only draws 70 watts so one 20 minute workout could run the laptop for over an hour.
Want to make your kid's pedal for their TV time? See the PowerPak accessory and plug their TV into the PowerPak instead of the wall!
The Pedal-A-Watt may be used with out PwerPak to store power that may be used at a later time (see the PowerPak below under the Accessories Explanation section). The PowerPak may then be tapped at a later time when the energy is needed. Simply plug your appliance into the PowerPak's outlet.
Want a simple and cost effective way to show users and onlookers that the Pedal-A-Watt is creating useful energy? Our Light Bulb base accessory plugs right into the Pedal-A-Watt (with 12 ft. cable with cigarette lighter plug) and takes a typical house lightbulb of 20 watts to 200 watts.
The Pedal-A-Watt bicycle stand is an excellent addition to an existing battery system that may already be charged from the photovoltaic panels, 120 vac grid power or wind power. The concept behind the Pedal-A-Watt bicycle is that electricity can be created from human effort and then stored in batteries.
We also recommend using the 12 vdc regulator / converter accessory anytime you are charging a battery or PowerPak (see Accessories Explanation section below).
Clean energy will become more and more important to our world in the future as more people, especially in up and coming countries like China, require more power that, unfortunately, creates pollution in many cases.
