Interesting there are a lot of doubts one can have... financing, does it perform as expected to scale etc.
But of all things the science behind the idea is proven concept. If you believe in tornados then this concept shouldn't be much more difficult to picture. Essentially a tornado is when a massive. Warm air (lighter) mass and massive cold (heavier) mass cross paths they create tremendous centripetal/centrifugal (can't remember which lol) force that has devastating effects
In swet tower same concept.. super dry (light) air mass you pump a bunch of water in the top air absorbs the water making air right at top of the tower far heavier than air below/around. That air falls for 2250 down in hollow concrete cylinder that's 1200 ft wide. That's a lot of movement at the bottom air can't escape but through wind corridors where turbines are in place, power generators that energy is sold to the grid.
There is a lot of risk in other categories the science behind the technology isn't one of them! Keep digging
