Innovations for Third World Countries

Here are innovations that are making a difference in various parts of the world

1. The Socket Ball, a power-generating football invented by two Harvard students which stores energy when kicked about. A 30-minute game produces enough energy to light up a lamp for three hours, bringing light to communities without electricity.
2. Hippo drum, a rotating 90-litre plastic drum, which women could roll on the ground when fetching water from distant wells, a daily chore for many, rather than having to bear the load on their shoulders or heads.
3. Focusspecs, the nifty adjustable glasses which help address the problem of myopia in poor countries. They have lenses that can be moved along frames by turning a dial. This brings better vision to places where people do not have ready access to ophthalmologists.
