ucg the next big thing., page-7

on one of the earlier generators ,I remember they
experimented pushing water and air down into the burning seam to create steam and inturn this would increase pressure at the outlet end

i think it was trialed and canned....

Daryl Rattie ( not sure of spelling) mentioned on land line
the burn unerderground by nature wants to put itself out........

three things nessesary for combustion
fuel
oxygen
ignition

oxegen injection came later and im not sure if they are persisting with this ?
