It seems like we're in agreement here? Geothermal heat pumps aren't particularly novel, so it doesn't seem like engineering a solution is the blocker here. It's mainly politics.

Exactly, budget is an engineering concern, and in this case it's nigh impossible to engineer a solution, given the space and budgetary constraints.

The budgetary constraints are purely political though. Stuff like this has been engineered before at a reasonable cost (eg the Green Park station for 9M according to a poster above). So while yes things have to be engineered to a cost, it’s clearly not some impossibility high number.
