Discussion Overview

The discussion revolves around the potential use of gyroscopes for producing upward thrust or levitation, particularly in the context of concepts attributed to Nikola Tesla. Participants explore whether gyroscopes can create external forces or motion, and consider alternative mechanisms for propulsion and movement in various scenarios.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • One participant questions if gyroscopes could produce upward linear thrust or assist in levitation, referencing Tesla's ideas and the concept of "eccentrics."
  • Another participant asserts that an internal device cannot produce an external force, citing violations of conservation laws and Newton's laws of motion.
  • A participant suggests that the momenta of rotating masses in a gyroscope cancel each other out, proposing that turbines might be a more effective means of generating downward thrust.
  • Another agrees with the notion that a gyroscope would work against itself, stating that energy extraction requires an external source.
  • A participant raises a question about whether shifting a liquid mass between tanks in a vessel could cause movement in space, noting that the center of mass of the system remains unchanged.
  • One participant inquires about the behavior of a hovercraft with spinning flywheels on opposite sides, questioning if it would remain stationary or move horizontally.
  • A later reply reiterates that while shifting mass can create movement, the center of mass of the system does not move.

Areas of Agreement / Disagreement

Participants express disagreement regarding the feasibility of gyroscopes producing external forces, with some asserting that it is impossible while others explore related concepts. The discussion remains unresolved with multiple competing views on the effectiveness of gyroscopes and alternative propulsion methods.

Contextual Notes

Participants reference principles of physics, such as conservation of energy and Newton's laws, but do not reach a consensus on the application of these principles to the proposed concepts. The discussion includes speculative scenarios that depend on specific conditions and assumptions.

could gyroscopes be used to produce upward linear thrust? or be used to push something along at least? i was looking at an attempted recreation of teslas flying stove and i was wondering if powered gyroscopes could be placed at what he referred to as "eccentrics" to produce upward momentum and make the machine levitate. here is the site:

a cool concept worth looking into. i am trying to figure out if such a device could be effective in overcoming its own weight, or at least producing some sort of displacement of inertia causing it to move in a straight line in some direction?

No, there is no way an internal device can produce an external force. That would be a violation of several laws of physics, such as conservation of energy and Newton's laws of motion.

Tesla wasn't quite the crackpot people think he was - things like the site you linked probably are improperly attributed to him because he is a popular "mad scientist".
 
It would appear that the momenta of the rotating masses cancel. As much momentum is going upward outside as is going downward inside, or vice versa.

It would make more sense to use turbines to blow air downward.
 
I can't speak about your link, since it has been deleted, but I totally agree with Russ and Astronuc. The thing would be working against itself. The only way to extract any energy from a gyroscope is if you have some even stronger external source powering it.
 
If an internal device can not create an external force, would shifting(pumping) a mass like a liquid between tanks at either end of a vessel in space, shift that vessel back and forth in space?
 
If you had a device that was already floating by force down (eg hovercraft) and had fast internally spinning fly-wheels on opposite sides spinning in opposite directions (from the sides that is: left side clockwise; right side anti-clockwise), would the device remain fixed over the one spot? Or would it move horizontally?
If you had just one flywheel on one side of the hovercraft would the craft show any twist or remain stationary?

Sort of. The center of mass of the system never moves, though. That's the point of my statement.
