Reading your rst two letters last week (NCE, 29 March), I got to thinking.
Wouldn't it be great if you could hide ugly solar panels under all that despised asphalt and use the heat and cold collected to heat and cool buildings, then return the used water to the road surface to de-ice it in winter and cool it in summer, making it last longer.
Could it be that overnight you would change the perception of tarmacking roads, airports and car parks from a necessary (nay unnecessary some would say) evil into a worthy contributor in the nation's battle to go green?
As such a system is already commercially available and has been used in the UK as well as the Netherlands, where it was invented, the path to its door should be red hot with eager clients and contractors, shouldn't it?
Road Energy Systems are here and now, tried and tested, if you are putting up buildings and roads at the same time why not pop a Road Energy System using solar energy in there.
