Goddard had a vacuum chamber in his shop, a continuous circle of sched. 40 pipe or some such cheap thing IIRC, and was experimenting with ion motors. He had obtained the original patent.

Please cite your references. It would be a very interesting read I suspect. Thanks.

Speaking of Goddard, the BATF's thug boot stomping of the amateur and model rocketry will force the hobbyist and experimenter into the pulse engine technologies -- which require only some tubes, propane and a tweeter-like pulser with some special machineing. Gonna be pretty interesting, I'd bet!
