Updraft/Downdraft Solar Tower

One of the biggest arguments against solar power is that it is intermittent. This is less of an issue today now that large-scale batteries (e.g., Tesla MegaPack) are available to level out the grid. But, what if you could generate power from the sun 24/7.

Well, this device does exactly that. It combines an updraft tower which generates electricity while the sun shines and a downdraft tower which primarily generates power at night. According to New Atlas this experimental tower design is estimated tto generate a total of around 753 megawatt-hours of energy annually, with the external downdraft towers running around the clock to deliver about 400 megawatt-hours, and the updraft tower working more efficiently under the hot sun to contribute around 350 MWh.
