Solar energy is being used in Malawi. We saw evidence of this throughout the country.
The problem is that the tools used to harness the sun's energy are extremely expensive. They are expensive here. They are expensive there. They are expensive everywhere. And they are completely out of reach for someone who makes less than $300 per year.
This is one reason why we use the science of psychrometry when we build solar dehydrators. This eliminates the need for pieces of expensive technology so if something goes wrong, they can be easily fixed.
Rural villages in Malawi do not have access to solar conductors, batteries, chargers, and the like. In order for food preservation to be sustainable, the equipment used needs to be able to purchased, fixed, and used by everyone. We must not make it dependent on us. We must make it accessible to all.
