Calculate the specific impulse of that drive system. Now realize why
something anyone who has taken a course in E&M has thought of at least once
is not being built.

Its specific impulse is zero. Shawyer is either an idiot or a fraud.

Cool. Everyone just hates a cold cup of java...

Well this one is better than the last still photos, but I'd still like
to see more. Yes, it's nice it rotates, but a coil of wire with a
current (compass) will do the same trick. Let's see some actual linear
thrust next! |

A less than zero Delta-V is exactly what antigravity is all about.
Our Selene/moon L1 is offering just such a location, with a combined
Newtonian force of 2e20N/sec (-1e20 N pulling in each tidal force
direction).

How would it warm your coffee? He claims the microwaves don't leave the
waveguide. Which makes it a reactionless drive which are generally thought
to be impossible.

There's always waveguide leakage, as well as positrons attracting free
electrons.

Compare calculated microwave thrust to reaction force of a teenager
pissing a full bladder.
