The Idea is to move large amounts of water vapor high into the Troposphere, thereby blocking some of the sun's intensity.
Factors that contribute the Earth's solar heat gain include reflectivity/emissivity and greenhouse gasses. If carbon increases heat by trapping IR light, incoming IR light can reduced by making the atmosphere more reflective. What safer substance to seed into the atmosphere than water.
Cloud manufacturing Plant concept: Boil large amounts of water and emit the vapor, by convection, up a 4 mile tall heated smokestack. Heating elements are placed in the smoke stack to keep the temp above boiling so the vapor continues to rise without condensing.
The water vapor takes a while to reach the ground and can be carried on natural wind currents. A cloud high in the atmosphere casts a larger shadow.
