The March/April 2013 issue of Sierra (the club magazine) says wind is now
cheaper than any other form of electrical energy generation, at
$61-89 for a natural gas combined cycle plant with 60%
efficiency or coal at
$62-141 or $200-231 for an industrial gas turbine (eg
Capstone?), IF we remove
all subsidies for all forms of generation. But
conservation and energy
efficiency are still cheaper, at $0-50/MWH.
use a fully-enclosed shower with a continuous 1/4 gpm brass nozzle head
swivel fitting from McMaster-Carr in parallel with occasional 1 gpm sprays from
with a hand valve...
Drilling a hole
through the plastic disk shutoff valve in the sprayer T will
keep the 1/4 gpm
shower head going when you are using the sprayer to wash off

This $9.17 nozzle uses 0.2 gpm at 40 psi with a 60 degree spray cone...
Here's a $15.60 swivel fitting... http://www.mcmaster.com/#34615k71/=nm48wo
This uses about 5 times less water than a 1.5 gpm "low-flow" shower
McGill U's "Water Conservation and the Mist Experience" pamphlet suggests using a garden sprayer, eg this $8.57 1-gallon sprayer... http://www.walmart.com/ip/RL-Flo-Master-1-Gallon-Sprayer/13376324
Bucky Fuller's Dymaxion pressure mist shower used 1 pint per hour, ie 0.002 gpm, ie 2 milligpm, 750 times less than a "low-flow showerhead."
