A Light Powered From Gravity?

I think this would be worth a try. For $10 or so, why not?

    Wow.. What an incredibly.. stupidly simple idea. it’s the exact same way they used to power old grandfather and wall clocks before there was electricity.
    If they’re using LED’s they don’t need to turn much of a motor/generator. I wonder why they’re using so much weight though. I’d think that they’d need metal gears to handle that much torque/weight.

    Great.. simple.. idea..

    Simple idea that will work. The guy is not much of a salesman, though. He looks like he lives under a bridge.

    Cool idea. In fairness, it is powered by the muscles that lift the weight, not gravity. :-)

    Man has been using gravity powered electricity for a century.
    It’s called hydroelectric power.

    December 31, 2012 last day to buy 75 watt incandescent light bulbs. They’re still under $1.50 for a package of four…after that only new, pigtailed modern, 75 watt light emiting “green” energy bulbs costing some five times (or more) the incandescent ones will be available. Both 60 watt and 40 watt incandescent bulbs are also slated for the chopping block on December 31, 2013. Oh, almost forgot a most important fact…GE is the sole producer of these new 75 watt light emiting “green” energy bulbs in their newly minted Chinese factory.

    So:1) we have 240 coal producing electricity generating plants shut down, 2)an average increase in energy costs in 2012 of 32% and 3) now “green” energy light bulbs costing on average five or more( times) the price of the “old” incandescent bulbs, 4) incandescent producing light bulb factories in the USA shuttered…and this administration says inflation is under control??? Not on your sweet patootie!!! What country is this???USSA???Pray. Amen.
