Can Microwave Propulsion in Spacecraft Really Generate Movement?

Click For Summary
SUMMARY

The discussion centers on the feasibility of using microwave propulsion in spacecraft. A participant speculates on the potential of a microwave oven, specifically its magnetron, to generate thrust when activated in orbit. They highlight that while photons possess momentum and can theoretically provide propulsion, the effect would be negligible in a gravitational field. The momentum calculation is defined by the equation p = h/λ, indicating the relationship between momentum and wavelength.

PREREQUISITES
  • Understanding of microwave technology, specifically magnetrons.
  • Basic knowledge of photon momentum and its implications in propulsion.
  • Familiarity with orbital mechanics and gravitational effects on propulsion systems.
  • Knowledge of fundamental physics equations, particularly p = h/λ.
NEXT STEPS
  • Research the principles of photon propulsion and its applications in space travel.
  • Explore the design and functionality of magnetrons in microwave technology.
  • Investigate current advancements in propulsion systems for spacecraft, including light sails.
  • Study the effects of gravity on propulsion methods in various environments, including space.
USEFUL FOR

If I had a Microwave oven (minus the door), and I placed this at the back of a craft that was already in orbit, if I activated the Magntron, could this propel the craft?

Stupid question I know, but if it can be a source of propulsion, what would be the maximum or minimum craft to microwave ratio needed for motion?

I think the concept is feasible... just lol, you know, wouldn't strap a bunchof commercial microwaves to a spaceship for propulsion. Pretty sure light propulsion has been fooled with.
 
photons do have momentum, so propulsion is feasible but it would be way too small to actylly feel, at least in our gravitational field. If we were in space, we would still have little or no movement of the microwave.
The actual momentum calculation can be determined by:

p = \frac{h}{\lambda}
