I couldn't remember this word before posting:

It's an example of locally made tanks, pipe and hoses.

If the parabolic collector is mounted high enough it could revolve
steadily all the way around, just as the sun appears to. No tracking
is needed, just an occasional readjustment whenever you send the wife
and kids out to hoe the weeds and refill the upper tank.

AFAIK automated farming is a first-world luxury. As a kid I did garden
chores the labor-intensive Appalachian mountain way my father grew up

I agree - and so are adequate food, water, and shelter for (nearly) all

The whole point of my efforts is to make these essentials possible for
those outside a first-world context, and to see if solar technology
might also be stretched to include a few things lacking even in the
first-world: 'free' electricity and refrigeration.

The first-world has moved on since our fathers' day because they (and
we) worked hard to improve everything that could be - and when farmers
found some way to improve life, it was shared with family, friends, and
neighbors. I honor that tradition - and think it's worth continuing.

I'm pretty sure farm kids will never lack for chores. :-)

We may be talking past each other. I don't question the value of your
project, only the maintenance.

Outside of engineers I know relatively few people who can maintain our
common household technology, such as fixing a leaky faucet or toilet,
changing a spark plug, wiring an AC plug or outlet. There's a cynical
electronic insider joke that >90% of VCRs permanently flash "12:00"
because the owner couldn't understand how to set the clock. It's a
reminder to keep things very simple to use for most people and avoid
the complexity we techies are comfortable with.

As a test, see what percentage of the people you know can solder two
wires together or tie a square knot.

Your proposals are comparable to rebuilding a carburetor.

We may be, and I could well be mistaken - but I think the there is
enough motivation for users to learn and do what's needed.

That's discouraging to hear. OTOH, I'm not an engineer and I've done all
of the above - none of those things are difficult and all are made easy
just by asking someone who's already done the job successfully or by
making a trip to the library. Nowdays there seems to be a YouTube video
that makes it possible to learn how to do almost anything by watching
and listening.

Most of the people I know were in scouting and learned to tie common
knots - and I haven't ever needed longer than five minutes to teach
people to make consistently good (electronics) solder joints. If folks
don't know these things, it's because they haven't felt a need (or
desire) to learn.

Perhaps - yet that, too, is a learnable skill. (I just did a Google
search on [rebuild carburetor video], clicked on "Videos", and got 3,640
results - awesome!)

I think a lot depends on motivation.
