Just a quick tip for you "free energy" is totally impossible so anything you see with that phrase is 100% guaranteed to be fake.
I dunno about that. A solar still collects water using a pot, some vegetation, and sunlight. It uses energy to evaporate moisture out of the vegetation, which condenses on the plastic and is then pulled into the pot by gravity. Seems pretty free, except for the plastic and the pot. I guess if you want to argue that letting the plants grow or letting the sun burn away it's Hydrogen is the cost, then it's not free.
That isn't free energy, that's using solar energy. Solar energy is a totally real kind of energy. If you want to hardness the sun, buy a solar panel. It's still not "free", it's coming from the Sun.
Ok, yeah, that's what I meant to agree with when I wrote "I guess if you want to argue that letting the plants grow or letting the sun burn away it's Hydrogen is the cost, then it's not free." However, in that case, maybe the zero-point energy at which your argument was directed is also not free, and therefore your objection was misdirected. The way I think of zero-point energy is that it seeks to be at the same level everywhere all the time (like the level of a lake), so if we tap into it at all, we lower that level everywhere (everywhere
eventually that is, because the change in level spreads across the universe in a sphere at the speed of light).
In any case, I think loads of people who use the energy of the sun do to certain things (dry clothes, grow plants, etc.) would call that energy from the sun "free energy", and they are most certainly not talking about something fake. Perhaps misstated, but that's kind of a subjective call. We all have our own ideas of the proper meanings of words, right?
