Comment on Vesuvius

I estimated the real ecological costs at some point and it seems that they are near zero, even recycling the foil would make things worse, unless I just burn it for hydrogen. I do sometimes.

ha, I wasn’t concerned about ecological costs of the foil, though I bet you could just put an old shirt over it and have a reusable solution.

Those are quite transparent to harmful part of sunlight unfortunately. With light blocking devices, even a metal bell is less environmentally sound than foil - detergent and water to wash it occasionally have more footprint than a few meters of a few micron thick disposable aluminium.
