To keep turbine sales spinning, Immelt has turned to a process that partially burns pulverized coal in the presenceof pure oxygen to turn it into a flammable gas that can drive linked gas and steam turbines.
Small flames were noted in one of the two incidents reported when gases escaping from the battery were ignited by an electrical short-circuit in the presenceof ambient oxygen, but that was all external to the battery case.
As a result, the astronomers demonstrated in their research that the JWST should be able to detect the presenceof water vapor and oxygenin an atmosphere in just a few hours of observation.
