Godisa is an African word which means “to do something that is helping others to grow.”
There is a manufacturer of low-cost hearing aids in Botswana that calls itself Godisa Technologies Trust and its objective is “to develop practical technologies for developing countries and to create employment and training opportunities for hearing disabled people.” True to its objective, Godisa has developed the SolarAid system, a combination of a small hearing aid and a solar charger that is built to last at least two to three year and yet sell for less than US$100. Standard hearing aids sell for an average of US$500.
The specs are awesome: its size is only 115x20x70mm, weighs 150 grams, is weather resistant, and can be charged up to 300 times over its two-to-three-year lifespan. And since it runs on solar energy, it practically has no operating cost. The manufacturer has also drop-tested it from five meters.
Just think how many poor people can benefit from an invention like this. It is estimated that there are 250 million people all over the globe who are hearing-impaired. A great number of these people are impoverished and live in areas where modern technology is out of reach.
And another good thing about it is that Godisa plans to share its profits (from sales and royalties) with other projects and organizations that help others. I hope more inventors and manufacturers will be inspired by Godisa to do something that help others to grow.
Good invention practical and reasonable cost too.
