Impulse Engineering

Resonant cavity thrusters
The reader will see there are two points of view here. Not really. One researcher says this does not work. The Chinese say it does and they are using it. They are both right and not lying. The first
researcher needs to buy the Chinese equipment and test it. The theorist who says this device does not maintain conservation of energy is an imbecile and needs to go back to remedial nursery
school. I am 70 now and asked as a student at Hull University whether waveguides could be used for space propulsion. The physicist responded that a waveguide was closed, so the radiation had
to be let out at one end. Yes, I replied, so why not use a shutter like a ramjet, and that would work? Well of course a laser has this shutter device in its mechanism, since the coherent radiation builds
up. So it is very natural for lasers to be used for space propulsion. Further, the coherence of the radiation means that it is not spread out in the horizontal direction as it would be for a chemical rocket,
for instance. So it is more efficient from that point if view. Surely I cannot have been the first to propose this? It is so natural. The theoretical physicist who is complaining does not know or understand
Newton's laws of motion. Photons certainly have momentum. Of course, the current idea derived from special relativity is that they do not have mass, unless you think like Burkhard Heim that the
inertial mass is very small. So it is totally natural to use lasers for jet engines! Photons go out one end, and the device moves off in the other. It is very strange that the theorist does not undestand this.
He should be sacked together with the entire physics department, for not pointing out what I have described so simply!

High energy lasers

Well, a spacecraft using laser propulsion must have energy from somewhere. Thermonuclear, if available, seems the best. Here are three articles.
Thermonuclear fusion, Nuclear fusion and Supernova nucleosynthesis

Tesla coils

Solitons
