Turning Gravity into Light
In today's modern world we have ample amount of facility which can satisfy above our basic need, unfortunately this condition is not satisfied everywhere in countries like Kenya, India where millions of people don't have electricity to lighten their house even renewable energy(wind, solar, water) are hardly available at some places and they are using harmful fuels like kerosene to power their house spending 20% of their income. What is the solution?

What if we can charge your mobile with the help of gravity (weight) sound crazy right! Basically, it is a very ancient technique which is already been used. Gravity light is a type of portable hanging lamp which uses a counterweight/hanging bag weight which descends down to drive a generator through a gear mechanism which provides energy to light LED.

Project Description:


Skyfi Labs Projects
GravityLight is powered through weight. As the weight falls it turns a gear drive train, driving the DC generator that powers the LEDs. There is no battery, no sunlight, no solar and costs nothing to run. It takes 2-3 seconds on manual weight lifting the weight that powers gravity light, creating 30-35 minutes of light on its descent.

  1. DC Generator: A dc generator is an electrical machine which converts mechanical energy into direct current electricity. A DC generator consists two basic parts, stator and rotor.
  2. LED: LED is a light emitting diode which needs some amount of voltage to run which is fulfilled by a Dc Generator
  3. Gear Train: Gear train is obtained by merging teeths of gears in some particular arrangements to get an maximum or optimum efficiency a according to our need.we can manipulate seed,torque, power and RPM.
  4. Belt/chain: which connects the input gear and counter weight
  5. Weight: With the help of gravity weight will be moving downwards glows LED

Final Step:

Enjoy the free LED Glow for 30-45 sec by just giving 3 sec of manual input.
