John Bohmer, de Kyoto Energy, vient de remporter le 1er prix du Forum pour l'Avenir (Forum for the Future)assorti d'une somme de 75 000$ offerte par Hewlett -Packhard.
The Forum for the Future is a British NGO which is interested in sustainable development. In partnership with The Financial Times, the Forum has launched a competition in November 2008, whose theme was "the most innovative combat global warming."
Norwegian John Bohmer, based in Kenya, won the first prize for an invention of great simplicity: "Box of Kyoto", a solar oven that could well be revolutionary.
At the base of his invention, a simple idea: to make solar ovens more accessible by presenting a model very easy to do yourself, and whose cost would be only 6 dollars or 5 euros .
Kyoto's Box consists of two simple cardboard boxes, one slightly smaller than the other. The interior of the smallest is painted black to better retain heat. The interior and most of rabas are covered with aluminum foil. The two boxes are placed one inside the other, and covered with a sheet of acrylic glass.
It only remains to put the water to be heated in a container in the center of the smallest box, under the glass plate, and expose all the sun.
Temperatures in the kiln can reach at least 80 ° C, allow to cook, and even boil water, according to its inventor. John Bohmer
hopes his solar oven, available to residents Third World countries, will fight against deforestation, replacing the wood fire cooking - is still practiced by 2 billion persons, and to fight together against global warming by reducing emissions substantially dioxide carbon. Box Kyoto could thus reduce the CO2 emission of two tonnes per family per year.
The solar oven could also improve the living conditions and health conditions of millions people, and reduce fire hazards associated with cooking with wood. If the box
Kyoto can be done easily at home, hoping Bohmer get to produce it in large numbers. His oven is already produced by a factory in Nairobi with a capacity of 2.5 million cans a month. It plans to produce a stronger version, replacing the box from recycled plastic. If the box
Kyoto is especially suited to hot climates, why not try it also in developed countries and temperate in summer? After all, in these countries, too, boiling water has a financial cost, and is not neutral for the planet. In addition, Kyoto's Box is easy to perform and appears as a perfect science experiment to do with his students or children, even young. It's never too early to raise awareness of the ecology and become world citizens informed and responsible!
