In 2008, Nick Sireau (former director of SolarAid) and I got in touch with a design company in London called Therefore as, at the time, SolarAid was thinking about manufacturing a low cost solar light for the rural African market. Why is there such a need for light in rural Africa? This short video, which shows what life is like in rural Tanzania after dark, should tell you all you need to know:
Not long after getting in touch with Therefore, the team of designers called us in for a meeting, told us they had given the problem some thought and then showed us a presentation in which they took us through the key components for a solar light… identifying the batteries and the solar panel as the two most expensive parts…
So they decided to take batteries and solar panels out of the equation to reduce the cost….then scratch their heads about what they could use to generate and store energy instead…..
And they came up with….Gravity. Pure genius!

Good luck guys. The more quality lighting and energy solutions which can be developed for sale in the growing off grid energy market the better.
