Heat-seeking sheep pave way for roads that generate energy

Heat-seeking sheep pave way for roads that generate energy:

"It generates energy to cool buildings and roads in summer and heat them in winter. Other benefits include not having to salt roads in winter, halving maintenance to tarmac and reducing emissions."

We don't have sheep warming themselves on roads here, but roads which help to heat and cool buildings is a great idea. A renewable reverse cycle energy source which is actually utilising the artefacts of our modern, urban living. The sheep on the west coast of Scotland had inpsired a dutchamn to think of this and the Invisible Heating Systems firm has made it a reality in the Netherlands. Brilliant thinking!
