Idea Details

Idea Name: PuriTY
Slogan: Clean Water For All
Startup Domain: Clean Water
Abstract:
    Project PuriTY is an Ultra-Violet water purification product that is independent of the electrical grid as it uses the energy of a falling weight (i.e: gravity) to generate it's own electrical energy.
What is the unmet need in society that your idea will fulfill ?
    Every 20 seconds, a child passes away as a result of drinking contaminated water according to WHO. Natural water supplies contain bacteria making them unsafe to drink directly without disinfection especially for children in villages and rural areas. Diarrhoea is a serious consequence of this.
Who needs it ? How many would benefit ?
   The product is primary aimed at off-grid communities particularly rural settlements. Worldwide 894 million people live in the areas where safe drinking water is unavailable and rural areas of Pakistan are also victims many of whom lack access to a reliable AC grid.
How will the solution works
    A weight when lifted to a particular height has gravitational potential energy stored in it. When the weight falls back to the ground it turns a series of gears which drive a generator thereby producing electricity. Gear reduction is employed to convert the high torque of the weight on the first gear to high speed on the last gear connected to the generator. This slows down the speed of the first gear reducing the fall time of the weight. The resulting electrical energy powers a UV lamp.
Who are your competitors ? How is your solution different
    There are three competitors in the portable water purification business named Lifestraw, Steripen and HUL Pureit. They are either powered by the AC mains supply or batteries. Our solution required no external electrical power input and is suitable for remote areas as well.
