Seems to me that the chatGPT estimate was extremely optimistic.
The maximum energy built up will be limited by the input energy
during each pass of the storage beam.  If the cavity were one
meter long, the time per pass would be 1/c.  How much energy
does a 5 W laser put out during that time? 1.67e-8 J.

If the end mirror absorbs 0.00001 of the energy per reflection,
the maximum energy in the cavity would reach only .00167 J.

You might get a 10x improvement of reflectivity and make the
cavity 10 m long, but you're still a long way from your dream,
methinks.  A scales to weigh a 10 meter pipe seems a bit
unwieldy to me.  You think maybe I made a mistake?  Check it
out yourself.
