My father is 87 and still strong – especially in mind. He has clear memories back to his maternal grandfather (born 1861) and the way of life they had, and then his father through World War I, and of course what my parents went through at school, during the Depression (which hit Australia extremely hard too), World War II, and the raising of their family through the 50s and 60s boom.
He is part of the Greatest Generation, and he is not that unusual (well in some ways he is exceptional, not just through longevity) in his broad range of skills, independence, knowledge, but above all, his sense of community and a belief in a social good. He also dragged himself out of the working class, and now lives in old age quite comfortably with my mother. But they have never retreated to a individualism that is the dominant theme today – they are curious and interested in the world, and in old-fashioned values such as self-responsibility, justice, equality, and fairness.
We occasionally have long talks about the way the world has changed – at all sorts of levels. He is a total believer in Peak Oil, but equally, just about Peak Everything. The world may change incrementally, but by some measures the world has changed at lightning speed during his lifetime (1920 – ). He is a guy who can still use a wide range of beautiful hand tools, but is also quite au fait with the Internet – and everything in between.
He bemoans (as I do) the destruction of community caused by the motor car – and while he acknowledges the enormous freedom mass car ownership has afforded, he is very critical of the neglect of public transport, and the spread of suburban sprawl outwards from every city. Along with the neglect of public transport, there has been a major change in his mind – a neglect of the commonweal on just about every level.
He reserves his greatest criticisms for wars – especially resource wars. His (our) whole family has been dramatically affected by war – over many generations – and his strong anti-Vietnam stances were almost career-threatening at the time (he was a life long schoolteacher and then college lecturer). His greatest contribution to his small circle has been his long-standing resistance to mindless consumerism, and he and my mother both quietly shake their heads watching the rampant spending of their grandchildren, and all their friends.
They see the wealth these young people enjoy, but understand intuitively (and to some extent analytically) that it is simply not sustainable for very long. They are aware that the massive paradigm shifts will occur after their lifetime, but in some ways it is ironic. If the world did change dramatically while they were alive – it is in fact their generation that would clearly be best equipped to deal with it. Much better than my cohort (baby boomers), and certainly more than the iPod, plasma screen, jet-setting younger generation. Interesting – and scary – times indeed.
The APEC Summit concluded in Sydney on Sunday – and energy issues were virtually absent, despite the presence of Australia (as host), USA, China, Canada, Mexico, Japan, Indonesia, Malaysia, and so on. It is as if the whole world cannot emerge from the denial – to do so publicly would bring it all down in ways that are too unpredictable to be allowable.
Us seniors recall when the world was not so crowded.
Especially with lawyers.
We're trying to do something about the lawyer overpopulation.

Read The Compleat Angler by Izaak Walton. Written in the mid 1600s, it was one of the first books for the popular press. Long diatribe against lawyers in there (along with some great fishing lore.)
Excellent post.
The rot of unaccoutable fiat takes time to control the mind.

Cargill is a heavy duty name in Ag.
I have been reading about peak oil for several years now. I was really scared about it for a while. This spring I decided that the best response to peak oil that I could execute personally would be to start a garden. I read "The New Organic Gardener" and started the garden as a crazy project.
Low and behold, my whole family got excited about it. Everybody planted their patch of the garden and we had a huge crop and cooked it all up. We had an enormous amount of food and the yields were great. We pickled and preserved some and ate the rest. Getting my family into the habit of caring for the soil and growing and preserving foods will be good in case we ever need to grow our own food for real.
I want to put in a cistern that we can use to catch rain water for gravity driven irrigation next. Have any of you guys done so? Do you have any recommendations?
Here's a note from a related application. Just put in a pond w/ 10-ft of head above a new garden spot and have been investigating drip irrigation techniques. Most commercial systems require 10psi (or approx. 23-ft head) to operate as designed. So . . . low head applications require a different approach. I'm headed towards 2" diam. siphon line from pond into undetermined diam. distribution lines.
I work alot with gravity systems. For surface water and drip, I've never had much luck. Cleanest surface water always has some sediment, which clog emitters within a season, even at 28 psi in my experience. Need a good filter. Another problem I've had is bacterial deposits clogging emitters. That black head in the sun is a perfect incubator at times. Chlorine drip? Not worth it. I use large emitters for trees, but in my opinion, the constant checking of emitters and risk of losing a young tree in the orchard is not worth it. Easier to dump 5 gallon buckets.
Low head is a problem. At about 20 feet of head, (never checked the gauge for psi) I've had luck with lightweight 1/2 inch thread plastic impact sprinklers on pasture. I run 1 1/2 poly for a mainline, then 2 1 inch laterals, trying to keep cost down. You should lower friction losses with your 2 inch. Also had luck with 2 3/4 inch head brass nozzles on each end. 1/2 inch brass, esp rainbird, I've never had much luck with. They just are too tight to spin properly. The biggest thing is keeping any air out of the lines.
For low pressure sprayers take a look at 'wobblers'.
At 10 psi they will throw a 24' - 30' circle of water and throw nice large drops that aren't blown about by the breeze.
I've been using them for a few years and am quite happy with them.

Seems to me that going to 2" water line is going overboard. Unless you have a long run or are moving a lot of water it just doesn't seem necessary (or effective).
Check a micro hydro site for psi loss calculations.

For a low cost drip system visit a local restaurant/bakery and get some (usually) free five gallon buckets. Drill a hole or two just above the bottom, set them beside a tree and fill with the hose.
The water will flow out slowly and get absorbed rather than running off. And you'll have some idea of how much you gave the tree.
I agree with your thoughts on 2 inch. On another gravity system I also use 1 1/2 for mainline, probably up to 600 feet on 30 to 50 feet of head, depending on lateral location.
As I recall, frictional losses between 1 1/4 and 1 1/2 are about double, worth the pipe cost.
Another line, though, at 1800 feet and wanting 15+ gpm, was worth the money for 2 inch.
Wobble link looks interesting, any problem with clogging? You using their 1/2 line and tubing? What is your water source? I tried years back a homemade system w/o emitters where I just cut tubing to length to get a desired flow. Had clogging problems with it on pond water, running about about 25 psi on lateral.
Thanks for the thought, but I don't have 10psi but rather 10ft of head. Much different energy gradient. Many more options become available at 10psi, such as the one you suggest.
My calcs are showing approx. 24gpm after losses for my 2" PVC trunk line. Intended application is 4000SF vegetable garden, so I'm thinking I could use all of that after I try to branch down a number of rows.
24 gpm on 4000 ft is one heck of alot of water. Might as well just go furrow flood.
As I haven't done this yet the feedback is interesting. Thanks.
By my calcs 24gpm on 4000sf work out to just over 1.5hrs to apply a uniform inch of water. I was thinking this was just about right, but you're saying this is too much?
24 gpm, about 5 garden hoses on full, can give you real erosion problems unless it's really spread out. Tubing would require a maze to cover 4000SF.
Furrow irrigation is the choice among growers with flat land and plenty of water, which you appear to have. It's quite effective, having complete field saturation, as opposed to overhead which tends to overwater certain areas while leaving others drier. It works best after the crop is established, as it often can destroy seedlings. Any slope and you are liable to get gullies.
If you are limited to 3 or 4 psi, and wish to conserve water, I suggest a small gas water transfer pump, assuming the pond is too far from electric power. They usually will run a couple hundred. Like a chainsaw, the few liters of fuel it would consume are quite worthwhile in operating sprinkler or drip systems. Perhaps there are now reasonably priced solar pump systems you might find.
If your pond is just established, you might wish to wait a year to get a handle on its seal and evaporative losses. That could point you in a different direction, with some pond evaporative losses exceeding an inch/day.
Thank you very much for the advice, it's much appreciated. Would you have any particular reference sources for irrigation practices? Email address? I have a yahoo email account under the name 'onewoodturkey'.
If you get enough rain to make it worthwhile, you don't need irrigation. A rain catchment that supplies all your indoor needs is easy. Irrigation requires too much water.
