I would love this to actually work and be built, but I an dubious at present.

There seems to be lots of PR, videos, plans and discussion, but very
little happening in the real world.
Even their optimistic plan won't have an engine built before 2018,
with first flight after 2020.
That assumes everything works, tests go OK and no funding problems.
A lot could go wrong before 2020.
