Hamster-Powered Night Light 248

Posted by CowboyNeal from the electric-animals dept.
An anonymous reader writes "Though Skippy the Hamster powers this night light by running on his excercise wheel, the same concepts and low-rpm alternator design could be applied to a school science project using different energy sources! A small wind or hydro turbine could easily power this alternator. The Otherpower.com staff thought of building a hamster-powered nightlight a couple years ago at a rather, uh, soused company Christmas party. Then recently Analise, an 8th grader from Albuquerque, NM, contacted DanF through the AllExperts.com Science For Kids forum, asking 'Can a rodent generate enough electricity to power a light by running on it's wheel?'"

      A pretty good cyclist pedaling pretty hard (200-250W) would take 4-5 hours to generate 1 kWh (worth around 10 cents).

      If you were paying the cyclist (in the case of a gym, fortunately they are paying you), you're looking at $25+ per kWh. That makes solar look damn cheap!

      I helped design a extremely simple wind generatior system for 3rd world countries that uses discarded 55 gallon drums and car parts as the rotor to drive a pully and modified car alternator. (we designed it so the locals can get over 80% of the parts from abandoned cars that they come across)

      we have a few that have survived hurricanes easily and only threw the belt off.

      most wind generators can be extremely simple with no moving parts except for the rotor (Yes, it does NOT track with the wind, as it is vertical.)

      Animal power generation is certianly possible.

      the key is to modify your alternator/generator to use the surplus extreme power magnets and rewind the coils so it will generate decent amperage at low rpm's by adding more coils. (making your own alternator is easy with a car strut+wheelbearing+ break rotor)

      I have seen a generator that would produce almost 15 watts at 12 volts from a horse exercize merry-go-round. 2 horses generated an average of 5 watts from less than 12 dollars of parts while they mose-yed around in a circle for a couple of hours, and 99% of that cost was the magnets. certianly cheaper than any solar panels and every watt you pump into that battery is precious... It generated enough power in a small battery bank to light a workroom very well and for a few hours with a 4 watt CF flouresent lamp that makes most 40 watt bulbs look dim.

    If we were to get a human-sized hamster wheel, how much energy could I *generate* on it doing a, say, 30 min hard run every morning?
    If everyone did this, would it have an impact on our electricity usage in the homes - and provide an incentive for overweight people to jog (not only lose weight, but save money on electricity bills). Not only this, but it's good to jog on a surface which has your footfall a little higher than the point your foot leaves the ground (as a wheel would) because it lessens impact fatigue on your ankles and particularly knees.
