Gravity Energy

Progress hampering, corruption common, self crippling, easily dominated.  But not everyone in the first world wishes to advantage those geographically less developed.

British designers Martin Riddford and Jim Reeves recognized a problem that has more implications than just merely providing light.  Perhaps the most ambitious, most challenging and most noble of obstacles; energy.

A bag filled with around 9 kg (almost 20lbs) of stone or dirt is suspended by a cable from the unit.  As the bag falls, it activates the dynamo and generates electricity for half an hour until manually repeating rotation.  Works much like a grandfather clock.  The ingenious solution is based on the ever freely-present-on-earth laws of gravity.

The implications of this quite tremendous as further R&D improves efficiency and has the potential to power much more than LED light nodes.

Original launch for the Gravity Light was $55,000 to produce 1,000 units for less than $5.00 per unit.  But a short run on Indiegogo and more than $400,000 was devoted.  Easily an investment where only return being the fulfillment of the original launch plan is the worthwhile return.

No fuel, not solar power, not even a battery, no foreseeable negative impact to environment.

Respect to you Martin and Jim.  On this day, December 25th 1642, borthday of Sir Isaac Newton.
