Oil from Coal

The plants are expensive to build, might as well build nuke plant and hydrolysis plants to change sea water to hydrogen & oxygen for fuel cell use whose byproduct is fresh water which we are short of. Still hydrocarbon fuel with the standard greenhouse gas as well as other NOx, sufuric acid, nitric acid....products of combustion. The process of converting the coal to oil is also very energy intensive. Hitler ran his war machine one coal derived oil because it was all he had access to, not because it was inexpensive or efficient. The process leaves large quantities of nasty & toxic waste, including radioactive waste (most all coal is low grade radioactive) Coal mining itself is a dirty process with large amounts of environmentally damaging waste and requires large slurry lakes. These require damms which have collapsed in the past causing major tragedies. We barely keep this under control at current levels of production. Now lets say we increase it ten fold.... The best direction we have to go now is hydrogen which can only be efficiently and economically produced using nuclear energy. It will produce the minimum amount of waste which can be reprocessed and disposed of on site by drilling holes to 30,000' (we do this right now for deep oil and gas) stacking 10,000' of waste into it, cap with 1000' of leaded concrete and back fill with dirt. |

Of course, this will have a large environmental impact. Jay Chan |

Jay Chan- Hide quoted text - - Show quoted text - The sugar cane industry in south Florida almost wiped out the Everglades as we know it. If not for a smart few, the farming practices would have completely ruined one of the most diverse and ecologically important areas on earth. |
