Discussion Overview

The discussion revolves around the concept of using electromagnetic (EM) waves to induce movement in solid materials through their mechanical resonance frequencies. Participants explore the theoretical framework for achieving propulsion by energizing materials and applying pulsed EM waves in phase with their oscillations.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants propose that solid materials have inherent mechanical resonance frequencies that can be modified to induce propulsion through mechanical vibrations and pulsed EM waves.
  • A participant theorizes that pulsing the EM wave in phase with the material's oscillations could potentially move the material forward by striking molecular bonds at specific moments during oscillation.
  • Another participant questions the feasibility of this approach, suggesting it may function similarly to radiation pressure, which exerts force on materials.
  • Some participants express curiosity about whether mechanical resonance can effectively be harnessed for propulsion, while others emphasize the necessity of emitting something to achieve propulsion, referencing conservation of momentum.
  • There is a suggestion that any emission would result in an equal and opposite force on the source of the EM waves, raising further questions about the mechanics involved.

Areas of Agreement / Disagreement

Participants exhibit a mix of curiosity and skepticism regarding the proposed method of propulsion. While some support the idea of using mechanical resonance, others challenge its viability and draw parallels to established concepts like radiation pressure. The discussion remains unresolved with multiple competing views present.

Contextual Notes

The discussion does not clarify specific assumptions about the properties of materials or the precise mechanisms by which EM waves would interact with them. Additionally, the mathematical framework for the proposed interactions is not fully developed.

Here's a weird idea: solid materials each have an inherent, but potentially modifiable mechanical resonance frequency. Step 1- energize the material mechanically by inducing vibration (ie. increasing the amplitude of occillations). Step 2- strike the material intermittently with an intense and pulsed electromagnetic waves (EM frequencies corresponding to bond energies within the material so that it can induce mechanical movement), pulsed "in phase" at the mechanical resonance frequency of the material inducing propulsion.

Any thoughts?

and how do you think any sort of propulsion is achieved ?
consider what is occurring in an oscillationDave
 
theoretically you would pulse the EM wave to be "in phase" with the oscillations, striking the molecular bonds at the moment during the oscillation when the material is moving away from the EM wave. This, in theory, would move the entire oscillating material forward.

I don't see any reason to think this would work any differently than the force exerted by radiation pressure.
 
you're probably right. But I wonder if there is a way to use mechanical resonance of materials to induce propulsion.
 
You have to emit something to get propulsion (or change the velocity of something coming from the outside). This is just conservation of momentum. So what do you want to emit?
 
Most likely there would be an equal and opposite force on whatever was emitting the EM.
