Solar-powered tent keeps food fresh

Belgian designer Arne Pauwels has invented a tent-like structure for food to help smallholder farmers in hot, dry regions reduce spoilage of their harvests. A small, three-watt solar panel operates a fan inside the tent that evaporates water, creating a humid and warm microclimate which can keep up to 150 kilograms of fruit and vegetables fresh for as long as 10 days. This requires around half a liter of water per week and less than 1% of the energy a refrigerator would need. More than 170 of these microclimate tents were already delivered to Afghanistan, Haiti and Uganda before mass production started in August 2015.
