Corentin de Chatelperron

French engineer, passionate by low techs. He developped a wiki platform that brings together his low techs. Message : The simplest and most ingenious solutions are the most effective

Microdigester

In Madagascar, he discovered a microdigester able to turn organic waste into biogas. This provides renewable energy and level down the dependance on fossil fuels and firewood.

Solar oven

In India, a solar oven uses solar energy to cook food. The aluminium panel reflects and concentrate the sun's rays in order to warm the food. This lowers harmful smoke emissions and promote ecofriendly cooking

Electricity-free refrigirator

In Kenya, he discovered a clay cooler refrigirator using water evaporation. Food can be stored without electricity.
