I order to optimize output from a solar park I need to know how to remove clouds in the sky in an economically feasible way. Output improves tenfold without clouds. How can that be achieved? Weather is apparently modifiable.

Some techniques, like adding or removing material nucleation particles, are too demanding.

Techniques are apparently efficient enough to be prohibited in international regulations, like ENMOD.

Cloud conditions are not trivial. NASA writes on the subject:

Although the basic idea of cloud formation is easy to understand, there is much more to learn. Peek beneath a cloud’s fluffy exterior, and you’ll find a world of complexity. In fact, clouds are considered one of the most challenging aspects of climate science.

It is thus not possible to conclude that clouds cannot be easily removed.

Svensmark et al. mentions a connection between ionization and cloud changes:

Svensmark, H., Svensmark, J., Enghoff, M.B. et al.
Atmospheric ionization and cloud radiative forcing.
Sci Rep 11, 19668 (2021).

I am especially interested in modifying the conditions determining the aerosol size in the cloud.

Work out which way the wind usually blows where you are. Build a large mountain range between you and the sea in that direction.

Most of the rain clouds will drop their rain onto the mountains, leaving you with fewer clouds.

Speaking hypothetically... you could make the mirrors sufficiently steerable to aim reflected sunlight at the pesky clouds, raising their temperature and vaporizing the water droplets. But that won't work if the cloud cover is complete. Then you'd best use a few hydrogen bombs to do the trick.

If the neighbors raise objections to this plan, you could instead deploy an air-fuel explosive, where a cargo plane full of gasoline sprays out the gasoline while flying through the cloud and then ignites the resulting air/fuel mixture.

  • $\begingroup$ @DavidJonsson, the question itself was manifestly unrealistic. In answering as I did, I was implying this. Let me know if you wish for it to be deleted. $\endgroup$ Apr 23, 2023 at 16:59
  • $\begingroup$ It is not well shown that the question is unrealistic. I will update the question later. Your answer is not in line with how Stack Exchange is supposed to work. $\endgroup$ Apr 27, 2023 at 15:01
