comment Do I need a ground for a new 240 volt 20 amp circuit?
Given that he has a transformer, I would guess a ground is only needed for the secondary side of the transformer. Does anyone know?

comment How should I go about installing a 12 volt DC residential circuit?
You are right, some apple laptop power supplies are wall warts. I have never owned an apple laptop thus I had never seen an apple laptop power supply. Anyway, if one had enough load that more than 15 Amps at 12 V was required, one could use the same technique as regular household power wiring: have multiple power circuits.

comment What size extension cord should I use for multiple computers?
In fact, many newer homes (2000 or later?) have a service of 200A@240VAC which could supply as much as 400A@120VAC. Mine is an example.

comment Why does my water smell bad after the water softener?
In my opinion, calling a greensand filter an iron filter is accurate. advanced-water-systems.com/technical/faqs/faqs_greensand.html

comment Can I use EPS concrete for a fire bowl?
You cite the flash point of DIETHYLENE GLYCOL as 255 degrees in claiming that a Sterno flame can easily melt EPS. In fact, flash point measures the temperature at which a fuel will ignite. In determining whether a flame will melt EPS, what you want is the flame temperature of the fuel in use. That would be parameter 4.12 in your MSDS. en.wikipedia.org/wiki/Adiabatic_flame_temperature

comment How do outdoor mist-cooling A\C units fare in real-world usage?
I liked "themister"'s web site, the information related to thermodynamics on it was accurate and correct. I'm not familiar with the filter chemistry they use. It is very interesting that it uses very little water, about 5 gallons per hour. You might be able to use DI water in that case. RO water boosted by a pump would also be possible. The waste would not be significant and you're not correct about the waste being high-salt. RO does not add minerals/chemicals, it just filters them out.
