True Innovation

Rolex Awards for Enterprise is a contest designed to support innovative ideas.

The winners of this year’s contest and their ideas are truly amazing and inspiring.

For example, Nigerian Mohammed Bah Abba developed simple cooler using two pots and filling the space in between with wet sand. The evaporating water causes a temperature drop and keeps the inner pot cool. The “refrigerator” doesn’t need electricity. Eggplants can now last 27 days rather than three. Farmers don’t need to sell their produce in a hurry and there has been a revival in the local pottery industry.

Be sure to check out all five inventions.
