It would be interesting to see your breakdown of the costs and man hours
for an H2 maser. I suspect that others would find cheaper/faster solutions.

You raise an interesting point.

I suspect that if a serious attempt was made at a caesium fountain by a
*group* of people, they might end up with donated parts from places like
NIST, NPL etc.

Commercial sponsorship  could conceivability be an option to funding such a
project, as could wealthy individuals like Richard Branson or James Dyson,
both of whom are interested in technically challenging projects.

$100 would not go far, but I personally would be willing to donate $100
towards the cost of such a project, just to feel part of it.
