A water storage power plant pumps water up to a reservoir when there is more power available than needed and lets the water flow down when power is needed.
For pumping water up, electricity is needed.
Concept / Idea
I'd like to create a water storage power plant, where the electric pump is replaced by the sun (see also image below):
- The sun would evaporate water on the ground.
- The water would rise up to a reservoir (as gas).
- The water can cool down at the reservoir and becomes a fluid again.
- The water is ready to flow down to produce energy.
- The whole circle would take place within an vacuum (or near-vacuum) environment so water boils by the sun alone.
- Is something like this feasible? Where are the pitfalls?
- What is the professional terminology for this concept? (it's difficult to search without one)
- Are there any publications/researches regarding this concept? (hopefully some, that usual human beings can understand)
