Wakati One

Upcoming Update

Wakati is a solar-powered cooler for fruits and vegetables.

Developed By Unknown

Product Description

Wakati One is a preservation technique for fruits and vegetables in developing countries. Keeping the quality of the crops is essential for expanding both the local market and the highly profitable export market, both drive local economies. With 45% of the crops that end up as waste (UN FAO) there is a lot of room to increase productivity, especially in countries like Kenya and Tanzania. Interview with inventor

Manufacturing/Building Method

Prototyped using Fused Deposition Modeling process with stereolithography. A final master was created for a silicone mould. Vacuum casting was used to create a run of 120 units.

Intellectural Property Type

Open Source

User Provision Model

Wakati is currently in pre-production. The organization aimed to start production after the summer of 2015. Distributors are NGOs, social enterprises and agricultural wholesales Interview with inventor. As of 2020, interested parties can become ambassadors and purchase the product.

Distributions to Date Status

At least 150 units have been sold.

Design Specifications

The Wakati consists of a tent-like structure with a 10-watt, photovoltaic solar-powered fan and water tray evaporator inside. A ventilator powered by a 10-watt solar panel gradually evaporates 1 L of water per week, generating a humid environment within the tent that keeps cells intact and prevents mold and fungi from spreading. Each tent is capable of preserving up to 1,000 kilograms of produce for up to eight days, greatly reducing potential food waste and giving farmers more time to sell their crops. Moreover, the tarp packaging of the Wakati can be stored and used at any point to mend ruptures that may form in the tent. The optimal use of Wakati One is outside, in a warm and dry climate.
