1. Solar Leaf : This technology is developed by professors at MIT, the Solar Leaf is made out of a thin silicon solar cell which is dropped into water in order to separate hydrogen and oxygen molecules, turning them into electricity by connecting them to fuel cells. The reason for the name ‘Solar Leaf’ is that the process imitates the photosynthetic process of a real leaf by converting water and sunlight into energy.

2. Eliodomestico Solar Still: It is a solar terracotta water filter system that can distill up to five litres of water in a day. It is designed by Gabriele Diamanti who developed the system to solve the issue of limited access to fresh and clean drinking water in developing nations. The Eliodomestico system converts seawater, which is poured into the top of the terracotta structure, into fresh drinkable water using the heat of the sun.

3. Uncharted Play:

The Soccket is a soccer ball that stores and converts kinetic energy throughout the day while the ball is in motion. Similarly, the Pulse skipping rope produces energy when it is played.

A thirty-minute soccer game or skipping session can power an LED light for more than three hours. The Soccket balls and Pulse jump ropes are already operational in developing countries in Africa and Central America – providing energy solutions that are not only innovative and renewable but also fun, engaging and healthy. Uncharted Play is company who aim to improve the enormous issue of energy supply in the developing world using these energy sources.

4. Infrared Solar Energy: Researchers have developed a solar panel technology that can capture not just direct visible sunlight, but infrared light as well. The technology is a transparent carbon-based solar panel, a feature that dramatically increases its application potential. Having an infrared solar panel that is transparent means the technology can be layered on glass, everyday surfaces and even on top of existing solar panels, increasing solar panel efficiency considerably.

5. Pollinate Energy: It is Australian Company working in rural areas of India. They provide access to clean, renewable solar lights replacing polluting Kerosene lights. So they are non toxic and non polluting and do not require continuous purchase of fuel to operate. In urban Indian slums, kerosene is burnt for light and cooking, which is expensive for families and is a significant contribution to global warming.
