Hot water plan to heat Glasgow city
Scientists in Glasgow say it may be possible to provide nearly half the city's heating using water from abandoned coal mines.
The team from Glasgow Caledonian University will spend the next three years mapping underground tunnels and reservoirs in 3D.
It is hoped heat from the water could be pumped to create geothermal energy.
The British Geological Survey has given researchers access to its 3D geological model of the city.
