Light from gravity

Yes, you read it right. While many are searching for sources to produce energy, some do manipulate the known manifestations of energy sources. Gravitational force is still an anomaly in terms of its source and stability. But using it as a source is an act of sheer brilliance. Manipulation of a force of unknown source to a source is sweet as petrichor.

Dysania isn't an unusual thing in humans, it has inspired many inventions from remote to mobile phone. Agitation of serving with conservation gave the awesome creation of gravity light.

Gravity light is powered by just a lift of weight. It isn't a tedious process of production of light. The magic of gravity does the trick of dragging the weight down which inturn rotates a motor which makes a set of led glow. The luminance is almost 5 times the luminance produced by a kerosene lamp light.

The tutorial is simple as follows

∆    Fill the bag with weight (about 12kg).

∆    Lift the bag using the orange cord .

∆    Bag falls slowly creating light (about
        20 mins).

∆   When the bag reaches the ground it
      can be lifted again.

Gravity Light is installed to provide a 6ft/ 1.8m drop of a 12kg weight. This weight is lifted by a person pulling the orange cord. A pulley system which effectively reduces the mass making it feel like  a 3kg. Once lifted, the weight then falls very slowly (about 1mm / second) , gravity playing it's vital role .

This movement powers a drive sprocket, which rotates very slowly with high torque (turning force). A polymer gear train running through the product turns this input into a high-speed, low-torque output that drives a DC generator at 1600 rotations per minute.

This generates about a tenth of a watt to power the onboard LED and two SatLight LEDs. Together these produce a light more than 5 times brighter than a typical open-wick kerosene lamp.

Once the weighted bag reaches the floor (after 20 minutes), it is simply lifted to repeat the process.
