Solar Power Tower
The Solar Mission project is based on the "Solar Tower" design by Professor Jorg Schlaich from the University of Stuttgart, Germany. The basic principle of operation is the use of the Sun's radiation to heat a very large body of enclosed air. Being warmer than the surrounding atmosphere, this air will begin to rise. By causing it to flow through windmill-style turbines on its journey up a tall chimney, electricity can be generated.

Every hour, the sun gives us more energy than the whole population uses in one day.

2 billion live without the benefit of electricity.

The Freeplay Foundation
The Freeplay Foundation is unlike any other non-profit humanitarian organisation in the world. Its sole mission is to enable sustained delivery of radio information and education to the most vulnerable populations via self-powered radios.

Working mostly in Africa, where affordable energy is scarce or non-existent, the Freeplay Foundation collaborates with professionals in education, health, agriculture, peacemaking, and voter education - all sectors where radio can play a vital or even life-saving role.
