[ RadSafe ] Boeing just patented a jet engine powered by lasers and nucle...

[Brennan, Mike (DOH)]

I have to admit that coating the inside of the chamber with U-238 is a design choice I did not see coming.  I also have problems wrapping my mind around fusing enough D-T to produce the required thrust without having to use some type of reaction mass (such as air).  On the other hand, running a lot of unconditioned air through your fusion chamber adds an interesting engineering challenge.

On the other hand, I understand the requirements to demonstrate the workability of a design in order to get a patent are fairly low.

Laser Induced Inertial fusion - Hmmmmm.  All of the LLNL National Ignition Facility - including the lasers - in a jet engine!!??

Yes - this may be a bit ahead of the times.

But then an LBL researcher is very close to reproducing SLAC on a desktop!!  Using lasers of course - what else these days.

I've heard of "getting a jump on things" but to actually get a patent on technology that doesn't even exist yet.

I'm not so much surprised that someone might apply - but that the patent office would approve.....

I guess the strategy is to patent whatever wild dream you might have and then when someone works very hard and applies their genius to invent it
- its yours!!

I guess I'll submit my patent for time travel!
