Maybe a ceiling fan is a good starting point. A 4 foot fan at low speeds generates something approximating wind, and in principle you can mount it on a wall instead of a ceiling to get a more natural wind direction. At higher speed you'd probably have to mount it in front of an opening of similar size as the blades to get wind instead of turbulent vortices though.

Or these vertical ceiling fans: https://www.lostcanyonwoodworks.com/x/cdn/?https://storage.g...

Perhaps only in the first experiment?

I wonder what solar cells were used in the project, and if modern advancements in solar power would change how systems were engineered. Battery technologies have improved as well.

I think this is a critical experiment, and there shouldn't be one. There is a nonzero chance, increasing every day, that these technologies will be needed ON EARTH from collapsing ecosystems and extinction-depleted biological interaction graphs.

Clearly that means it's time to declare the experiment over, right?

It also feels very 1980s inside.
