“We needed a cheaper alternative and I was tasked to develop a solar water heating system for the company. A good coincidence because, back at school, I was already in the process of designing a solar water heating system. I took the opportunity and delved deeper to research and further test the viability of my design,” says the 26-year-old graduate of Mechanical Engineering for the University of Nairobi.
Solar water was hot in the 1980s, but due to the poor performance of some of those early systems, it faded into relative obscurity. Nobody wanted to deal with scalding water on hot days and cold showers at night.
Water heating accounts for 17 percent of a typical home’s energy use, so it’s a ripe target for savings.
