British, Chinese and now NASA teams seem to validate fuel-less microwave space drive...

One interesting tidbit is that the Air Force apparently announced in 2015 that the X37-B includes a "Hall effect thruster" testbed built by Aerojet Rocketdyne.

The X-37B had been in orbit on a mission designated Orbital Test Vehicle (OTV) 4 since a launch on an Atlas 5 from Cape Canaveral Air Force Station, Florida, on May 20, 2015. The Air Force disclosed prior to the launch that the OTV-4 mission would carry a Hall effect electric thruster developed by Aerojet Rocketdyne and a materials science experiment provided by NASA, but did not disclose other plans for the mission.

Well, we knew the explanation would be weird, right?

So the Enterprise will look like a trumpet. Is the bridge in the mouthpiece or the valves?

Maybe just the engine nacelles will look that way?

Prediction: This will not be proven or disproven to work in 2018.

Bold!

More bold but not that much of a risk is that still holds true by 2020.

My money was always on that it was going to be a testing error…

Wow, still?!?!?

Someone spend the cash to put one in space!

If only we stopped testing, it would've worked!

McCulloch says they nicknamed it the Bart Drive after Bart Simpson’s spiky hair.

I am glad a bunch of experimental physicists couldn't come up with a more apt name. At least this one isn't 'EMDrive MCEmDriveFace'.

The current design is calculated to provide a thrust of about .012 Newtons (equal to the weight of a paperclip, or a raisin) for one kilowatt of power

Yeah, I dunno why someone hasn't just stuck one with a big honking battery on a SpaceX rideshare. If it moves, hurrah! If it doesn't move, then it and the funding both burn up.

I thought the Chinese were supposed to test it in space a couple of years back and then never said anything?
