Man-powered blimps: their history, recent developments, practical construction and propulsion, even advice on getting in shape. Can be read as a companion to the same author's A Practical Guide to Constructing Small Gas Blimps if you intend to build one, or by itself if you are only interested in the history and current state of this -niche technology.-

This is the final volume (Appendices) of the series Build Your Own Hot-Air Balloon. Unlike the other volumes (I-III), it does not cover only hot air balloons, but rather discusses gas balloons and the spherical enveloped generally used for them. The information in this volume is NOT needed to complete a hot-air balloon project, although there is some coverage of one-man (harness type) hot air balloons.
