# Electromagnetic Propulsion (Not EM drive)

## Recommended Posts

If you decide to try this Experiment please post your result.

Fact:  like magnetic poles in a magnet repel each other.

Question:  Shouldn’t two transmitters operating at the same frequency and phase also repel each other.

Supply:

A: 2 Transmitters operating at same frequency and phase, they should be directional most likely low frequency may be best.

B: Water environment: pool, bath tub, big bucket with water.

C: Toy boat

Experiment Idea:

1: Obtain two transmitters that will operate at the same frequency and phase.

2: use a body of water for experiment (pool, tub.. ect.)

3:  power up one transmitter on a small toy boat.

4: place boat on top of the water.

5: Power second transmitter and aim at boat.

No.

I beg to differ; I do have a background in Electronics.

The real question is how much apart the two transmitters have to be, it may be that they may have to be too close to each other to really work(that's what you may mean).  The other question is what effect will frequency be?

Photons carry momentum, so the act of emitting or absorbing photons will impart momentum, if the emission or absorption is not spatially symmetric.

However, the force is very small. F = P/c, where P is the power of the emission or absorption (it must be the value of the asymmetry, not the total power). An antenna absorbing 3 Watts of power from one direction will feel a force of 10 nanoNewtons. i.e. if it has a mass of 1 kg, it will be pulling a nano-g. Strap in!

If it's 2.4 GHz it'll heat water molecules. It's frequency used by microwave ovens..

Check this website and search for "GHz" to learn more about frequencies used by this device.
