The Wakati isn't a refrigerator, but it does keep fresh fruit and vegetables from spoiling quickly without refrigeration. In developing countries where electricity is scarce, a means for keeping produce fresh can make a big difference in profit and livelihood for a farmer because more of their product can be sold before going bad. The Wakati is a solar-powered, sterilized microclimate that stores and ventilates fruits and vegetables. A 3 W solar panel rests atop a tent-like box. The solar power runs a ventilator that gradually evaporates a weekly supply of about 6.7 oz of water, creating a humid environment within the Wakati that keeps produce fresh.Crops can dry out quickly after being harvested, but with the Wakati system the humidity keeps the cells of the crops intact and the acids and enzymes inside the cells that would normally begin to digest the crops are kept under control.
