Foucault Pendulum debunked?

Quote:

Claim #1; The experimental apparatus consists of a tall pendulum free to swing in any vertical plane. "Free to swing in any vertical plane." is the claim we will be examining. With a little google search we are able to find many links that show an electromagnetic drive is used in museums to act upon the pendulum. [1] [2] [3]. It appears that in modern situations the platform the bob is swinging over has an electromagnetic ring that is considered a drive. This electromagnetic drive is usually calibrated to help steer the pendulum in the motion that is intended by the pendulum's desideratum. Additionally, the construction of the Pendulum includes a Charron ring. A charron ring is the stabalization system or dampener used at the top of the pendulum's construction. While the cable attached to the bob moves in it's oscillation, the cable contacts the Charron ring. This forces the cable to move on one plane. The Charron ring also is used to prevent elliptical movement. Since the cable comes briefly into contact with the Charron Ring in each period, the oscillation plane no longer oscillates in relation to the ground during that period. In consequence, the rotation of the oscillation plane “slows down” and a complete turn takes slightly longer than expected. What we find here is a misrepresented claim of free movement. It is readily seen that the slowed motion of the Pendulum by the Charron ring dampener necessitates the electromagnetic drive to continue to move the Pendulum. The contacts with the Charron ring creates a force and further the electromagnetic drive creates a force. These forces alone remove "free movement" from being a reliable claim for this experiment. http://ift.tt/1GVHPRk

For the record, I have found one without a magnet. http://www.youtube.com/watch?v=M8rrWUUlZ_U
Also it looks like the original one in Paris didn't have one.
He also mentions the allais effect which is debunked here: http://ift.tt/1GVHSwj
He makes other claims which I don't understand...

Claim #2; The actual plane of swing appears to rotate relative to the Earth. The first thing about such a claim is that it is not a statement of fact. It appears to do as they say it does. Again, a desideratum. The construction of the anchor at the top of a Foucault Pendulum makes use of an anchor point that allows rotation. Where as other pendulums use a back and forth motion that does not allow rotation to occur at all. Consider Pendulum clocks as an example of a non-rotating anchor point. The Pendulum is allowed to rotate in a complete circle over a period of time. Besides these facts of construction, No one has ever seen the Earth rotate by watching a Pendulum swing. Conclusion of claim #2; FAIL Claim #3; At the equator the Foucault pendulum will be at a fixed plane of back and forth motion not showing any gradual sideways rotation that is found at other locations around the Earth. Here is where we look into the Foucault's sine law. The Equator brings a peculiar division of 0 to the equation. "For a given longitude the surface velocity varies from 1 EVU at the equator to zero at the pole even though the angular velocities are all the same." [4] At the equator the pendulum axis is perpendicular to the Earth's axis and the sine of 0° = 0. " The time to observe a full rotation is equal to one day at the North Pole with the time increasing with decreasing latitude and not observable at the Equator (infinite length of time)." So, zero according to the Foucault's sine law is the equivalent of meaning infinity. That way in Ecuador it has even been described as a setting that could be fit for some actualization of "infinity" the infinite fixed plane of perpetual horizontal motion. There is zero value in the equation at the equator, yet this zero has been given infinity as a value. This is basic math that has now become a farce. Anything divisible by, or multiplied by zero is zero. Conclusion of claim #3; FAIL
