DD> 1) Lack of water to flush

 okay

DD> 2) Much less liquid pollutant to dispose of 

 bullshit (actually humanshit) Your "liquid pollutant" is just water
that you add at the smelly end. I can't imagine there'd by any problem
with a weeklend retreat in the bush (unless your body processes food
at a phenomenal rate).

 I love the way political correctnesss changesover time, for no
scientific reason whatsoever. Back in the fifties when septics
arrived they were a wonder of ecology, but like all things, slowly
over time the "ecologists" (translate as yuppy wankers) got it on for
septics. The grass was too green where the septic flowed, it just
wasn't natural and for all anyone knew, it was probably radioactive
in the water table (another youppy-wanker term). Mining uranium
"creates" radioactivity, why not septics... or whatever insane logic
yuppy-wnakersuse when being politically correct.

 The fact remains: shit in, shit out. Of course the bacteria is going
to break faeces andurine into nutrients (use pollutants, it sounds
much more sinister), but "compost" is such a nicer word than
"septic"
so now they have smelly composting toilets with no liquid pollutants,
just solid pollutants... actually nutrient.

 I think it's a hoot. I wish I could undo my engineering background
and join this wonderful world where anything is possible and one silly
opinion is worth a hundred scientific facts. But the wankers have uni
educations too... they've just never used it, except to invent loony
theories they never have to actually try, or build, or use.      

DD> Evey bit of sunlight I can capture means less panels to buy...

 That's not quite true. It's more complicated than that. Every bit of
sunlight will put the maximum into the cells IF THEY ARE NOT ALREADY
CHARGED. As soon as the battery is fully charged, you may as well
point your solar cells at the ground.

 A better criterion would be the state of battery charge at sun up.
If you have a low charge (at whatever time of year and weather
condition) *THAT's* when you would have to add more cells. What I said
about pointing the cells at mid summer and midday is probably a more
optimum result, when your main load is a refrgierator. My guess is
that your lowest charge is in mid summer.

 It's 15 years since I did any measurements on solar cells, but
thet were very directional, and here in Sydney the latitude 34S made
50% difference. In other words, pointing at the winter sun halved the
output from the summer sun. It also halved 2 hours either side of
midday. *That's* why I said that afternoon shade hardly matters.
