Constant thrust in a closed sysyem with no energy expended is impossible. What they are describing is just the latest version of the Perpetual Motion Machine hoax.
If it were true, then you could easily provide free energy to anybody, anywhere on the planet. Simply construct a vacuum container, attach the cone device to a dynamo and, voila, fred energy!
This is hogwash.
“Free” energy too! ;)
Hogwash?
Yes. It appears to ignore the issue of generating 60 Watts of RF at 2GHZ (in the test example).
This sounds like pop science BS, but appears to be a real experiment at JSC.
I’m very skeptical.
It’s not free energy or perpetual motion. It uses electricity to produce the microwaves. Kilowatts....
I don't think you understood the article. There is absolutely energy expended.
However, there is no reaction mass involved, or more accurately, you don't have to carry it with you. Other rockets make thrust by expelling "stuff" at velocity out their exhaust. Bad news: you have to carry the "stuff" with you until you're ready to expel it, and it's heavy. This "rocket" may be making its own "stuff" (photons) as it goes, so the "lifting heavy stuff for thrust" problem goes away. That's the big win.
