Free water for Africa
Chill water from the air This works for all hot countries! We need a source of free electricity. I would favour a little steam plasma power plant. My American friend validated that a 30x1cm steam plasma generate a constant 1 MW of heat. This will drive a little steam turbine to produce 500 kW of electricity. We convert into AC mains current. We do this remote from the town! Is really that an awful lot of heat we were prefer not to be near. 1 H₂O+PL→2(E²+L+X-ray) So we use the heat to drive a little commercially sourced steam turbine. And here I fall back on the life saving Dr. My father to his National Service after the Second World War. We use a little pump to compress a gas. Increasing the pressure by 50% should amazingly enough increase the air temperature by 80° C. We lose that heat to the air. Higher up and remote from the village. We then pump that gas through family insulated cylinders...
