It has always seemed wrong to me that we don't have anything like the return pipe of a district heating scheme for people with cooling needs to dump their waste heat into.

Of course that needs DH in the first place, then a heat exchange/heat pump circuit to move the waste heat into it. Even with the embodied energy of the plant I imagine it would be worth doing - especially when we don't want to be adding heat to the air in an already over-heated city when a/c units are running flat out.

Oh! for a planned city or suburb/district, with all this built in. When the Sheffield tram system went in (besides renewing all the old services) they put in district heating mains... Only problem is that the heat source is a waste incinerator which apparently can't be fed without massive amounts of lorry-miles scavenging burnable stuff from all over Yorkshire!

Presumably they burnt all those needlessly cut down tree's after buying them off the private contractors with chainsaws & expensive police assistance!? because sheffield council were more afraid of getting sued by the contractors than doing the right thing by their citizens in a climate emergency
