Today there is a temperature difference of 50 degrees Celcius between the northern and southern part of Norway. In Finnmark it's so cold that boiling water will turn into ice and snow if thrown into the air. In Vestfold where I live it's almost spring these days.
This makes me wonder if there's a way to generate power from this temperature difference over such long distances. It's maybe 1700 km to drive by car, so I guess a device must cater for roughly the same distance.
Is there a workable way to do this, economics aside? If there is, what then if we bring the economy into the picture?
