Top 10 Ways to harness the Nature’s Power

3. Solar Cells harvest the colors by tearing up Sunlight apart

Solar Cells That Tear Sunlight Apart to Harvest Color

Solar cells are only eleven to fifteen percent efficient based on the calculation of amount of sunlight solar cells absorb and their output in the form of energy or power. However, DAPRA is working the ways to increase solar cells’ efficiency by more than two times. A design has been finalized in which nanomaterials are used. Wavelength of the sunlight hitting the system will be broken down and then each color will go to the specific cell through a pipe. This will enable the system to absorb more light. This prevents the need to use the whole spectrum, rather, each color will go to its specific cell and the overall efficiency will increase.

2. Solar Powered Water Purifier

Deepika Kurup, an Indian girl has developed a solar water purifier at the age of 14 only. By spending only a few bucks, people can drink neat and clean water. This system just requires the exposure of Titanium Oxide and Zinc Oxide to sunlight. This water purifier has the ability to reduce coloform from 8,000 to 50 only while E. coli bacteria are eradicated completely.

1. Self-Contained and Self-nourishing Food System

A Self-Contained Food System Disguised As Corporate Art

A retail company from Japan has build up a new system named Aquaponics, which is used in hospitals as an art piece. This system has the ability to grow plants and fishes at the same time. Water in fish tank is filtered by the plants and sent to the fish tank via pipe and at the same time, waste material (nitrate) of fish is used for the fertilization of plants. Large-scale production of this system will increase renewable food resources in the areas where there is scarcity of water.
