Abstract:
The principles of the classic rotary Wimshurst machine,
which produces dc high voltage by regenerative electrostatic
induction, are used to develop a new alternating high-
voltage machine. This device has no electrical inputs
but can spontaneously produce either dc or three-phase ac
high voltage, depending on external connections. The
machine constructed by the authors produces voltages in
excess of 18 kV which frequencies of operation up to 2 Hz.
Improved design can extend the voltage and frequency
operating ranges. Analysis is extended to include multi-
phase, multi-frequency operation by modeling the device
with a distributed equivalent circuit representation. The
natural frequencies of the system are calculated where it is
found that many overstable modes are present.

US Air Force’s 1950s supersonic flying saucer declassified | ExtremeTech
Tighten the strap on your tinfoil hat: Recently declassified documents show that the US Air Force was working on, and perhaps had already built, a supersonic flying saucer in 1956.

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.
