Recycle the sunshine

Interesting idea here to keep roads ice free in winter. Is this better than using salt on roads. The old question of how drivers of salt-spreading lorries get to work could soon be answered under government plans to recycle summer sunshine collected by Britain's roads and use it to keep them ice-free in winter. The Highways Agency plans to install pipes underneath a section of road to gather solar energy in summer and recirculate it in winter. Experts hope the scheme could be a way to treat the roads which are the first to freeze. Listen to the podcast here and see if you think it is useful? All I can see is roads now flooded when these pipes burst and water is wasted – am I just cynical? Full article here.
