Solar is a highly efficient way to heat water. Combine it with underground storage, and a year-round system can be created where the system can cover heating requirements in the winter and cooling in the summer. The Dutch company Ooms Avenhorn Holding BV has taken this concept and moved it a step forward with the Road Energy System® (RES).
Rather than putting tubes on a rooftop, RES lays the collection system within concrete -- think the black asphalt of a road or runway. The piping connects to undeground storage areas. Remember the last time you walked on black asphalt on a sunny August day and you understand the heat being transferred into the water in the pipes. This water is then transferred into the storage area. On demand, in cold weather, the hot water is used to heat buildings and to keep the road above freezing. After cooling, the water is moved into cold storage to provide air conditioning for summer months. A year round solar/geothermal heating/cooling system for both the road and buildings. The renewable combo greatly reduces electricity requirements (and thus pollution) and the cooling/heating of the road reduces maintenance requirements (and lowers/eliminates deicing and plowing requirements in winter).
And it is deployed. "Solar Energy collected from a 200-yard stretch of road and a small parking lot helps heat a 70-unit four-story apartment building in the northern village of Avenhorn. An industrial park of some 160,000 square feet in the nearby city of Hoorn is kept warm in winter with the help of heat stored during the summer from 36,000 square feet of pavement. The runways of a Dutch air force base in the south supply heat for its hangar."

Patrick,
I bet you can apply this technology to your life if you try.

To address your US sucks remark(i believe there was a lack of inovation crack also!)
Why not really make a difference?
Isn't Asphalt 93% silica and 7% petroleum?
So why not loose the Petroleum refine the silica in mass, then teach the world a new way of laying asphalt.
Seems to me that you have then created a collector and generator of solar power that lands right in the lap of a presently functioning industry, already in place, over budgeted in over 60% of the world and that holds to a common and focussed purpose
of witch is the install ,upkeep, maintenance and eventually the replacement of this very interesting creature that we refer to as the Highway. That being said , a couple of high voltage strip inverters down the shoulders and center divide along with a beacon light at point of grid tie that could span every major overpass on ramp,off ramp.
Well doesn't this pretty much give you a road map depicting all micro grids that the utilities seem to have concerns over?
While if I am not mistaken, would land you enough available surface area (or collection space ) to address the worlds power needs to date in one fell swoop!
Can't begin to think of the ramifications that would be dropped in the Electric Vehicle Industries lap. (charging stations? Who needs them?)Why not teach the world a new way to build a charge controller?
Couldn't all vehicles be charged while driving during the day time at no cost to the vehicle owner other than the already exurbanite highway tax that he presently pays.
So Marsbeyond,
There is your good old fasion USA( or am i from Mars?) inovation at its best.
You now hold this inovation in your shakey little hands(or is that sucky?) What will you do with it?
Will you become the greatest American hero and fufill your destiny or will you conform to the picture you paint for the rest of the USA and just sit there and suck?
Whatever.....

But there's one mistake, Denmark and The Netherlands (the dutch) are not the same country. The concept is being developed in the Netherlands, not Denmark.
