Porcupines' quills, or spines, take on various forms, depending on the species, but all are modified hairs coated with thick plates of keratin, and embedded in the skin musculature.
Produce up to 400-Watt of power for free in your own back yard. The wind turbine will produce more power up to 400-Watts at 28 mph. If the wind dies down the turbine will continue to produce power in winds as low as 5.6 mph. This wind generator is used to charge 12-Volt batteries and mounts on any 1.5 in. Schedule 40 pipe.
Energy density in stored elevated water is high: So one liter of water per second on a turbine generates 720 watts of power. If this power can be continuously genreated for 24 hours per day for one month then the total number of KWH per month is then: 720 watts x 24 hours/day x 30 days/month = 518 Kwh/month.ECAUSE ITS CHEAP! for the consumer average price in the PNW is around 4 cents per KWH this is 3 times less than the national average! Low cost to the consumer reflect relatively low operating costs of the Hydro Facility.
