Tamil Nadu, South India - scientific breakthrough in Carbon battle

Reported three days ago by the BBC, the scientific achievement to turn carbon molecules into a usable product  (baking soda), has caused ripples around the world.  Though on a smaller scale than many other projects concerned with the carbon emission problem, it is a signal of hope in this important, and urgent, area.  Tamil Nadu became known to many people some years ago, for less happy reasons.  How fortunate that success has been won here in the climate change battle.
