Gravity Lights - Campsite / Power Outage Lights with No Fuel or Batteries


Recommended Posts

When I saw the indiegogo page for this concept, I immediately thought of emergency preparedness and wilderness camping as great applications for this new (old) idea, which is basically to use a slow falling weight to propel an ever-finer set of gears to drive a DC motor, which then powers an LED light source.  Instead of batteries, all you need for light is a sack of rocks or any other weight.  The concept is basically the same as how grandfather clocks and large tower clocks work.

 

If youre interested, check out the link to their page here.  Since it's an indiegogo at this point, your money will net you different things depending on how much you spend, but much of your investment goes towards expanding production of these lights in Africa, where they're badly needed.  I kicked in a few bucks, maybe you will too.

 

Regards,

Patrick
