This is both a shower thought and a stupid question but I think it fits this community better.
Since air conditioning is apparently heating the local environment while cooling down a house I was asking myself whether it would be possible to basically either build a layer of glass/plexiglass right over the actual outer structure of a house, leaving a tiny gap between wall and glass, or at least put a house in a kind of glasshouse dome with a double glass wall. And consequently inject a sulfur compound, calcite etc into that “gap”, basically creating a very tiny micro-atmosphere that has that sun blocking effect.
Would that work, just logically/technically? Would the environment heat up less, more, or just the same as with geoengineering in the stratosphere? Would it even cool down a house/keep it cool at all?
My grandma used to water the garden around the house and spray water over the roof on hot days. Try that first.
I’ve sprayed my roof because my ac can’t keep up. I didn’t notice a difference, but it felt like I was at least doing something. DO NOT spray your ac condenser outside. Best case, you slowly build up hard water deposits on the fins and reduce efficiency further. Worst case, you rust out components not intended for direct/continued water.
