That is precisely GravityLight which is a Low Cost Lamp. Imagine a light source is activated in 3 seconds and provide you autonomy for up to 30 minutes, all this at no cost. Sounds like a great thing to save electricity, but the focus of this development is to provide light to rural areas mainly in India and Africa which do not have much electricity. .
Energy Challenges: There Isn’t an Easy Solution
The epic challenge of the twenty first century is filling the gap between energy provide and demand with clean, reliable and cheap energy. whereas new sources of energy ar bit by bit dynamical the landscape, product made of fossil fuels still heat our homes, fuel our cars and power our computers. Despite extraordinary advances in technology, speedy economic process in countries like China and Republic of India would require additional energy. Some solutions ar being enforced nowadays, however several can return from following generation of entrepreneurs, engineers and scientists. The Low Cost Lamp is an effort to address Energy Challenges.
How this Low Cost Lamp Works
The operation of these low-cost lamp is through the use of gravity, it takes place bags or objects weighing approximately 10 kilograms. Its use is primarily intended to replace lamps that run on fuels such as kerosene, even the lighting is much better.
Currently the project is being funded on IndieGoGo , already exceeded the target of 55,000 USD to cover the production process over 1000 lamps and accessories.
The main advantages of using Low Cost Lamp operating with gravity
- No batteries required, so that does not involve spending or wear over time.
- Low cost.
- More accessible.
- Using LED lights to avoid attracting mosquitoes.
- It avoids the use of kerosene produces 244 million tons of carbon dioxide a year.
A very interesting technology that is more feasible to use solar energy as the cost of the panels is usually higher and depends on how much energy is collected during the day. This is the first initiative, but those who are behind this project seek to offer more power options for low-power devices and improve the quality of life in rural areas.
