This book perhaps demonstrates where you can end up if you read too many of Lindsay’s books. Richard Buxton did just that, and realised he could produce good quality charcoal, and generate electricity at the same time, using the ‘Producer Gas’ given off during the making of charcoal as fuel for a portable, caravan type, generator. It is a neat idea and the author describes all the stages carefully, but you do need a fairly sophisticated retort, plus “scrubber’ for the gas, and to modify the generator motor’s carburettor. To a clever person like you none of this should present problems and, when the system is up and running, you have non pollutant fuel, plus electricity. Good stuff! 63 page paperback, well illustrated with drawings, schematics and photographs.
