Small-scale rural and peri-urban dairy farmers in areas with intermittent or no electricity, predominantly in Africa and Asia. Thermogenn’s initial target market is Uganda, where there are an estimated 2.9M smallholder dairy farmers, who own an average of 4 cows each, producing an average of 60 liters of milk per day. About half of this milk is produced in the evening and needs cold storage until the next day when it can be transported and sold.
