Which is why Ceres sounds so good as a source of water.  It would take
far less energy to get a lot of water from Ceres than from earth to
the moon.

You want to run a pipe between Ceres and the moon to power up a
turbine and beam the energy back to earth? Where's the liquid supply
of booze comin' from?

and the 400 M km of pipe? Otherwise using ships or tankers you still
have to stop the carrier in orbit around the moon.and then  climb out
of the gravity well when you have delivered. Lots of v there.

Spectra of organic compounds have been observed from Ceres. IK am not
arguing Ceres is a comet, just that organic compounds are common on
bodies with lots of water in space.
Who needs a pipeline, just shoot it from the surface of Ceres with a
mass driver or light gas gun, I think orbital velocity is roughly .1/2
mile/sec compared to 17 mps for earth. The Delta V to get to earth
capture is much much less than getting water from earth.
