Avro, has it ever occurred to the people who are so much against coal, that perhaps there could (should) be some funds allocated to R&D to find a way to burn coal CLEANLY, rather than just shut down the coal industry, putting countless coal workers, miners, technicians and their families on the unemployment line? Has it ever occurred to the same folks that CO2 is no more of a green house gas than water vapour? Has it ever occurred to them that there is an almost limitless supply of coal and not using it would be a crime against mankind?
