Airforce Base Makhado, in Limpopo, now has solar geysers designed to reduce the damage of  limescale build-up and the amount of electricity used to heat water in domestic housing. Piloted as one of the projects implemented through a five-year partnership between the South African National Energy Development Institute (SANEDI) and the military, this installation is part of ongoing research to ensure sustainable energy, as well as quantify energy, cost and emissions savings through energy efficient and renewable energy interventions.
