- If you make it work, yes...
-
- Mr. Dean tested his machine by running it on a bathroom scale.
- It vibratrted up and down, so the scale readings oscillated; they
- seemed to oscillate about a midpoint that was less then the dead
- weight of the machine. Skeptics talked about the limited accuracy of
- this method of measurement, and suggested an alternative: mount
- the machine so that is thrust should be horizontal, and suspend it
- by a long rope from a tree branch (or hook in the ceiling, etc.).
- If it really works, then the rope will slant, like so:
-
- O -- the hook
- \
- \
- \
- X -- the machine
-
- I think Mr. Dean never consented to try this.
