demonic - have a read back through b101's posts re UCG, extracting gas from brown coal seams. Don't know much abut the process or technical issues, but could be a fuel source.
Definitely don't want to go round digging up brown coal for these units. I spent a few months working in North Bohemia (Czech Republic) around the Brown Coal basin - you could feel the air pollutants stripping away your throat lining. Good job there was plenty of very cheap and good quality beer to compensate!
