Inertia Drive

[Yucca]

Shawyer's "EM" drive will soon, I hope, be tested in the definitive environment--outer space.
Smarter people than I have looked at Shawyer's maths and they think there are rather large errors.
I personally don't believe all experimental artifacts have been excluded.
What would be the effect of a tiny pinhole in the container, or an ion wind from some wiring or component at relatively high potential?
I just don't know, but since his math is suspect and the device appears to violate CofM, I'd put money on it being an error of some kind.

I´m not sure whether it works or not either.

If I could see the rotating test rig enclosed in an airtight, grounded rigid shield that rotates with the whole rig and it still rotated then I would say it works. It might be something he should consider doing to improve chances of investment.

Shawyer says that the reason it works is because two seperate inertial frames are set up within the system due to relativistic effects, the maths is way above my head.

What did Mr. Walden said about his device? Has he made a prototype yet?

He made a prototype, and it behaved as his computer software model predicted, and he says that it passed the pendulum test. However the bearings in his first prototype overheated and damaged the prototype, and I believe that he's waiting for funds to finish making the second prototype.

Now that his patent application has been published, I'm hoping someone else with access to a machine shop can duplicate his prototype (and his success with the pendulum test).

thanks for the answer FredWalter.

You said Mr. Walten passed the pendulum test. What is the pendulum test? I never heard about such a test (sorry).
For what is it good for? What means that he passed this test?
I'd like to replicate his invention. But there are not enough informations out there (overunity.com). I have the patent file but that's not enough.

Andreas, you might like to look at

(scroll down to the Inertial Propulsion section)

Just for starters.

Thanks TinselKoala for the links!
Does Naudins device works like Mr. Waldens invention?
Do you have more information about Waldens device?

Thanks
