Robert Franke, Germany

Robert Franke from Beethoven Gymnasium in Berlin, Germany, won the Stockholm Junior Water Prize for his design of the Aquakat, a solar-driven reactor for the decontamination of industrial wastewater.

Robert’s project represents the highest objectives of the Stockholm Junior Water Prize. Young inventors like Robert will help lead tomorrow’s engineers as they find solutions to the many challenges we face in protecting the earth’s water.

Franke’s invention, the Aquakat, uses the photocatalytic properties of semiconductors to degrade persistent chemicals. His device is claimed to be cost-efficient, environmentally sustainable and of particular relevance wherever solar power could be used as an energy source.
