well all that heat wasted by coal burning power stations
what most people forget is that the UK infrastructure water, power and gas are slowly becoming nothing more than a joke! but in the case of water desalination plants they require a massive amount of heat apart of the process as new power stations are being built i dont see why they dont use the wasted heat to basically bring water to 60-80 degrees cannot see why not..
In the past we had back boilers for hot water and heating matrix's which used a coal fire to heat the water and from experience very efficiently..
I think they saying goes stop wasting and start using!
on a side note.. down with the 5p plastic and PAPER bag tax..
