Yesterday we had an interest Lab experience, in
which an advanced student showed his version of the so called ‘electrostatic
lifter’, This device basically have two
pieces isolated each other, one is a wired
triangle, the other is a 3-flat surface triangle, which are connected to a high voltage source
about 30 Kvolts. This device levitates thanks to its light weight. There is a similar device
in this moment at You Tube – Electrostatic
Lifter – .
We developed some theories, like ‘ions
wind’ which seemed acceptable. The problem came arise when we inverted the polarity and
the device continue levitating exactly in the same way. We changed positions in space and arrived to the conclusion that the force
always is actuating along an axis surface ===> wire ( in reality it has nothing to do
with anti-gravity) . How is this possible ? How can
it be polarity independent ? Does the table
platform has an effect ? (it does´t seem)
I couldn´t find a simple explanation. Can
anybody helps me to explain the phenomenae ?.
