Re: Parasitic energy

Another concept touted a while back was to exploit the moorland sheep effect.
This is where it is noticed that sheep tend to sleep on tarmac roads at night because the roads have, during the day, absorbed more heat due to the black surface than the surrounding ground.
The proposal was to run pipes under the roads so that heat absorbed could be pumped to reservoirs during the summer, helping cool the roads and stop the tar melting (normally a rare occurrence but probably something else we can expect from global warming) and released in the winter to help prevent icing.
