All this fuss is simply part of a quest for more grant funds.
Sumply stick with the tried and true, proven technology. The radiometer! Scale it up, multiple drives... May have to harden the glass to protect from meteor strikes and Chinese missile attacks...

Heck yeah, the radiometer! You could put propellers on your space ships and not have to use rockets. Well, I’m off to the Patent Office...

I think the EM drive is circling around a problem being solved, but I don’t think it is there yet.

How I feel about the EmDrive is summed up in the words of Dr. Timothy Ferris, who said in his wonderful video The Creation of the Universe,: "it is extremely unlikely, but on the other hand it only has to happen once."

As a reminder, we could make flying machines 30+ years before they arrived at the correct reason that heavier than air could fly. It was the same argument.

90 years to Alpha Centauri?
"Starchips" can get there in 20 years, and don't require questionable physics.

Not trying to start anything.
But Bernoulli predates the Wright brothers by about two hundred years? Kind of settled science.
So you are suggesting that the Wright bros were unfamiliar with Bernoulli’s principle?
Maybe they clammed up for fear of Bernoulli’s descendants and a lawsuit?

It’s easy to prove these day. Build it into a cubesat and get SpaceX to launch it for you.

But I’m happy on the third rock in from the sun?

Its a microwave rocket. Set it on “Baked Potato” for Mars orbit.

But that might slow it down?
No free energy, never!
Maybe you could warm your lunch over the power supply for the magnetron.
And cold C-rats never killed anyone.
Not counting the pork and little MFers.

Gravity still IS. We can describe the effects and predicted forces and have mathematical theories that get the right answers but we still don’t really understand the essential mechanisms without using mystic terms such as “curved spacetime” and other hermetic angels-on-the-head-of-a-pin pseudo understanding.

The Planetary Society in Pasadena, California, has a cubesat in orbit right now with a solar sail. Which is the spaceship version of the spinny radiometers of our youth.

But Bernoulli predates the Wright brothers by about two hundred years? Kind of settled science.Bernoulli's principle is only a very small part of what it takes to build a working flying machine.

Starchips weigh about 5 grams, that’s roughtly the weight of that nickel in your pocket.
That’s much more of a diet than I’m willing to do!
