[Vo]: Mechanical prototyping

I'm looking for what amounts to a high quality erector set for performing mechanical experiments with magnets, gyroscopes, etc. Where can I get kits like shown on the Steorn videos or seen in chem labs to hold up various items in arbitrary positions, as well as bearings, pulleys, etc. Thanks,

BTW I also have an untried design for an autonomous lifter (designed to take off vertically and hover for a few mn while carrying it's own power supply, would be a world first if it works), if anyone is interested in experimenting it you're welcome. Be warned though that it requires thousands o

Sure Harry it's ion wind. Naudin's comment, athough somewhat misleading, is correct too. The collector (bottom negative armature) is indeed attracted upwards to the "parachuting" positive ion cloud _generated by_ the corona wire (the ion cloud, dragging ambient air along, is pulled downwards wit
