Hi,
BTW, it only costs about 0.53 kWh/kg to lift something 200 km above the Earth's
surface against gravity. Li-ion cell
phone batteries have about half that. However gasoline is about 12-14 kWh/kg,
less when you need to take along your own
Oxygen. Ideally one would use a small nuclear or

Wonder if they were kept any drones aloft for the whole time?
Say, having enough microwave energy

Speaking of resonant cavity devices, state secrets and the EM Drive
specifically, there is this:
https://www.universetoday.com/143870/x-37b-lands-after-780-days-in-orbit-doing/
It is strongly suggested that a prototype EM Drive was aboard. No comment from
officials.

Well, I know that in a tornado (vortex in air), you get high and low
pressure zones. That is why, for example, even though the air is moving in
circles parallel with the ground, a house gets

Oh? What is a "hole in the vaccuum?"

Hi,
You might consider adding a mirror image of it along the axis. Wide ends
together. Maybe then it will generate a
"hole in the vacuum" in the middle?

The Wiki listing for "resonant cavity thruster" is a place to start as there
are good links to more detail

Thank you JonesBeene. The thought that the mass of the device may change
under certain conditions had not crossed my mind. Can you refer me to some
good papers on the Shawyer truncated cone?
Yes, I am familiar with Bird Wattmeters. However, in this experimental
setup, nothing is matched to a
Very interesting.
The first thought that came to mind when I saw your design, esp with the
golden rule geometry -- is that it could be a more favorable wave guide than
the Shawyer truncated cone (EM drive) for the purpose of directed thrust using
RF.
