Re: To the skeptics...
Lockheed-Martin hasn't asked for external finances since the Almighty was young.
That is already a warning.
A second warning is their diagram, where anything that does not fuse ends up slamming into the containment vessel.
A third warning was no mention of mitigation neutron embrittlement.
Finally, they're talking magic. Useful energy from something the size of a jet engine. OK, nice source, the collateral equipment necessary to make the damned thing work *and* cool and make work is a hell of a lot bigger.
Now, add in the fact that deuterium isn't cheap by far and tritium is royally expensive...
Finally, despite what our intrepid author has said, fusion is trivial to achieve. People all over this planet, even on Old Blighty have produced fusion devices. Neutron generators are available for sale, the more hazardous requiring various regulatory hurdles to overcome. The overwhelming majority of those are fusion units. Every hydrogen bomb on the planet and most fission bombs today have a neutron source that is a fusion unit.
But, for those, energy input is much higher than the output.
The former examples are curiosities, the latter, neutron sources.
Sorry folks, I call bullshit.
If asked to invest, I'd invest in cold fusion. Just for the comedic results.*
*I have many other objections, some are based upon things covered under various NDA's, some of which could put me in prison. So, no. I'll not discuss some other objections. Anyone who knows collegiate physics will know where I'm thinking, mostly.
