Gravity Light -Lamp that Shines
Gravity Light – Lamp that Shines without Electricity or Batteries
Most of us take electricity for granted, seeing it as a normal part of the civilized world.
In contrast, in many countries, electricity is a luxury that people can only dream of.
For this reason,Jim Reeves and Martin Radford a team of two designers / innovators are working on an exciting innovation that should be an alternative to fuel lamps .
Consequently,many people will welcome this innovation in homes around the world, including those in third world countries.
What is the Gravity Light
Gravity Light or gravitational lamp is the name of their innovation that has to make free and cheap light wherever she’s gone.
Furthermore,gravity light is cheap mainly because it is a simple design.
In fact, the small movable mechanism drives a dynamo connected to an LED lamp.
A simple plastic bag filled with stones or earth powers the mechanism.
Gravity is the one that performs all the work and that moves bag slowly down.
The bag sets the mechanism in motion at a small, constant speed, which is sufficient to drive the dynamo and power the lamp.
So with a lifting of a full bag to some specified high until she reaches the ground light can shine for about 30 minutes.
To start the lamp to illuminate again all you need is to attach the bag at the top and cycles will again begin to repeat.
To put it again in a position to start to generate light it takes about 3 seconds.
On this way it avoids the use of batteries or need of any source of electricity.
The lamp can work as long as it does not break or exceed the planned working hours for such a lamp.
Low Cost Green Light
Although Gravity Light is currently selling the lamp for $10, the designers expect to reduce the price to $5 over time.
To raise funds for the development of this project, its creators use crowdfunding.
So far they through indiegogo.com have collected much more than they had initially.
However, they are hoping to rise even more as Gravity Light would fall into series production and would be available to more people in the third world.
