lifters in a vacuum
Posted: Mon Jan 01, 2007 10:33 pm
Hey gang,
I just stumbled upon this very interesting post in the lifter forum and I thought some of you might enjoy reading the entire thing. It was penned by Anthony Holland. (Mr. Holland, if you happen to read this, would you join our happy crew? Just follow directions for joining the forum which Paul has put at the top of the discussion board. We would appreciate hearing from you.)

The part that caught my attention especially was your statement:
"Sorry, I've only read this figure somewhere ...on the very low amperage
levels used by TT Brown...... maybe in the book by Sigma Rho... in
which the author publishes a letter from TT Brown describing how his
devices worked in vacuum at at least three different laboratory
locations and also that his power supply varied from 50KV to 250KV.
I've never seen anything that says brown had power supplies > 250KV,
such as you suggest below, but I suppose that is possible.
I've not seen anybody on the net experiment in the 100KV or higher
range yet when attempting flight in vacuum, but Brown clearly indicated
the voltage level had to be that or higher to work in vacuum. In some
recent vacuum chamber tests of which I am aware, there was a limitation
of only 15KV on the 'pass through' mechanism which would allow an
external HV supply outside the Vac. chamber.... so at that experiment
it was not possible to attempt to use a higher voltage using a power
supply external to the chamber, it simply would have arc'd over and
since the vacuum chamber was very expensive, it was determined not to
risk it at that time. It seems to be difficult to find a HV supply >
100KV with .001 amps or less (for safety reasons). I suppose maybe
somebody could build one but I don't believe you would be able to use a
metal housing high vacuum chamber. TT Brown used a large glass bell jar
for his vacuum tests. Some have suggested that tests inside metal
vacuum chambers distort the shape of the HV electrostatic field. TT
Brown clearly indicates in his notebooks and elsewhere that the SHAPE
of the field is absolutely critical to lift power.
Until somebody starts experimenting with 100KV or higher, in a non
metal vacuum chamber, we won't see any evidence of lifters working in
vacuum. Those who have categorically stated that lifters don't work in
vacuum have made a number of false assumptions upon which all of their
tests to date have been made."
Comments from our peanut gallery? NASA????
The only comment that I have is that I happen to have that book on my research shelf. Unfortuneately it is written in German, which I do not speak, but I can get the gist of many things. (The authors pen name was actually Rho Sigma.)
One of the reoccuring statments which I found interesting was " Where is Townsend Brown?"
