Geothermal or similar cooling requires a pretty significant capital investment in order to work. My guess is that a basic air conditioning unit is a cheaper and simpler fix in most cases.

The problem is that even that fix may be out of the reach of many residents of Karachi.

By "people" I meant governments, companies or NGOs. Sure a basic AC unit is cheaper for one person, but it seems plausible that a piping system like the one I described would be a cheaper way to cool a large area. Note that AC will cool one person's house, but contributes a net heating effect to the city.

This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.

Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.

To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
