KENYAS BEST INNOVATIONS.
Vincent and the non-electric cooler: Solar refrigerators are not a new idea. Vincent took it a step further and built a cooling system that uses recyclable water, and charcoal (heating/cooling agent) instead of electricity.

William, another innovator built  solar panel sun tracking device-which is a mouthful for a solar panel that ‘follows the sun.’ The light dependent resistors in thesolar panel take the position of the sun, tracking it using special tools which make the panels tilt towards the sun direction…automatically, giving them the best position for optimum solar absorption. David and his colleagues built GSM tracking devices which allow the user to do simple operations like switching on/off the lights, opening/closing doors and gates, setting alarms and turning on a cooker using the mobile phone. The series of devices use a sim card, an internet-enable mobile phone or computer and a text messaging system. “It can do many things,” said David, a young inventor, “passengers can tell how fast a car is driving and report over speeding vehicles to the police since it uses satellite tracking. When a car moves it can measure its speed and passengers can report such incidents to the police.”

Charcoal Stove
George Kabiru is also responsible for the creation of a charcoal stove, also known as a “solar jiko.” It is perfectly designed for the typical non-electric towns of Kenya, and it works best in cool, high-altitude regions. Simply an insulated wood box with two glass windows fastened over the top, one window works to allow in heat from the sun while the other promotes accelerated heat absorption. The sun’s reflection bounces against an aluminum coating, which then heats the box and adequately cooks food.
Washing machine The invention Kabiru is most proud of is his washing machine – a plastic container fixed on a stand and operated manually by turning a wheel.
He says he had people without electricity in mind when I made the machine.The machine can wash clothes, blankets, linen and canvas bags in it and it takes a load of 40 kilogrammes.
He sells the washing machine for about $68. So proud is Kabiru of the invention, that he has patented it.
