Concord residents have heard a lot in recent years about their gasholder, the handsome but crumbling brick building built to hold gas made from coal in the days before natural gas. (I’ve written at least a score of stories about it – here’s one.)
Those folks might be interested in this video, part of a series called Technology Explainer. Its a follow-up to a fascinating earlier video which explained why hurricane lanterns look the way they do, and goes into good detail about the development of manufactured gas and its many drawbacks. I heartily recommend it.
