Solar Powered Cardboard Oven
In their own words, the aims of the competition were:
- to raise the profile of green innovation and demonstrate that there are solutions and money can be made from them
- to find the best low-carbon innovations from around the world and help them find funding by showcasing them to a global business audience
- to help the winner immediately with a $75,000 prize to develop its project and bring it to scale.
With more than 300 entries, the final 5 products were the following:
- A feed additive reducing the methane produced by cows and sheep
- Hollow ceiling tiles with water circulating through them which cools rooms through evaporation rather than air conditioning
- Fabric covers for truck tires that can reduce fuel costs by 2% by reducing aerodynamic drag
- A giant portable industrial microwave which can transform biomass into burnable charcoal
- A solar powered cardboard oven, capable of cooking food and boiling water in, easily produced at a cost of 5€, about US$7
The competition was won by the cardboard oven, named the Kyoto Box by it’s inventors.
This extraordinary development enables families in the tropics where the sun is high in the sky, to boil water making it safe to drink, and to cook food. Crucially, this can be done without burning wood or other natural resources to make fires, or having to buy fuel.
It is this kind of very simple but revolutionary technology that is the key to positively transforming countless lives worldwide, while at the same time contributing significantly to reducing environmental destruction and damage to the atmosphere.
