I've been thinking about this for years and since people on this thread seemed quite informed in sciences, I'd just like to ask if it would be possible (or if it has been done already or is ongoing) to harvest the natural heat coming from our planet's deserts and bring them to naturally heat cold countries. The same thing for the natural Cold on the north and south poles being harvested to cool tropical countries naturally.
If you know of a project like this or any inputs would be very much appreciated.
