    Everything old is new again. We used to have clocks which ran on the same force. Why not invent a wind up light?

  2. There is one – we use it camping and our wind-up radio sometimes as well…cheers.

    How about 100 steroid-enhanced, 300-pound hamsters in a treadmill?

    1. I have a hunch the homes of the intended customers for this gravity light aren’t large enough to accommodate your device.

      Actually, mine isn’t either. Maybe Boeing would like your idea.

    Here is another solution worth looking into. http://www.youtube.com/watch?v=SBWi3NtND68

    1. Thanks, Alan. I featured the solar coke bottle lights last summer on CD!

    LED lights and cell phones…two huge impacts on rural productivity.

    I work in a rural area of Thailand. A cell phone can saves hours in a week in communicating changes to drivers, suppliers, etc. The smartphone allows even more hours to be saved in locating phone numbers, markets etc.

    The LED headlamp makes outdoor night work practical. Many Thai farmers and others now extend their workday by an hour when need be.

      And with these gravity lights they can work all night.

      Perhaps something to make their daylight hours more productive would improve their standard of living more than lights allowing them to work longer hours.

  6. this is dangerous maybe. we should regulate it.

    1. Yes – and maybe institute a gravity tax.

      If too many devices use gravity as a power source… the planet might run out, and we would all float into outer space.

      We need to be careful about things like this!

      1. Peak gravity? Who knew?

    This should be promoted to hunters, fishermen, campers, and hikers to help increase the chance of increased funding for research and development. The profits from these individuals could help lower the cost for the third world market.

      I’m not sure any of the potential users you mention would be interested in something they have to “wind” every 30 minutes in place of something like their already inexpensive propane lanterns which can be used for many hours.

  8. Do the math. The thing generates very little power. Not enough to light much more than the lamp itself.
