TOPIC: Coal and Coal Gas
There is a long tradition of using coal for heat and light in many places around the world. In the UK whole communities have lived for centuries around the coal based energy principle. Where petroleum may ignite and disburse during a pole shift, coal will be available during the Aftertime. It makes a lot of sense to use coal, plus there is a simple method to extract gas suitable for lighting from coal (and dry wood). Coal Gasification, as described, is a simple enough method that something akin to petroleum can be achieved, as a Troubled Times member recalls this was called Producer Gas in Australia during WWII.
