The mass of helium is 4.002602 g/mol. Divide by Avogdro's
number, and a single atom of helium weighs 6.646E-24 g. The
difference in mass is what powers the sun. Parent is simply
making the same argument on the scale of a proton split into its
parts. (disclaimer: I know, blabla deuterium, not protons and
neutrons. However, see the definition of a state function.) At
our plant, we have a water reclamation facility at the end of
our process, the same type of facility used at the water
treatment plant upstream. A WRF is common, iirc, in CA, but is,
afaik, the first of its kind here in MN. It is far more common
to discharge without the additional filtering and contaminant
removal provided by a WRF. The water we discharge is tested
biweekly for ammonia and phosphorus and daily for total
coliforms and biological oxygen demand. Ammonia and coliforms
are non-detectable ~99% of the time. We are doing a very good
job turning sewage into drinking water for the next town on the
river. He holds the liquid gold at 1127C. It
