Sir William Ramsey believes it will be possible to burn coal in the depths of the earth to produce gas conveyed by pipe to engines in a power house on the surface. "Bring your gas engines to the mouth of your pit or your bore-hole and produce your power there," urges Sir William. "You would thus have 30 per cent of the energy of the coal available as against 15 per cent available in fuel engines."
