  1. These mountains are not exactly "alpine". From recollection I'm guessing 800'? The horizontal difference is next to nothing compared to the continental requirements to connect the monsoon to highly populated areas. Which is many thousands of km. If the local suggestion is silly, then the rest is inane. Which is really why I was saying. In regards de-sal - they also swallow a lot of energy to simply sit idle. In terms of hydro, in Australia the water can not simply be lost. So that huge energy you gain flushing the water through is than countered by the energy to pump the water back again, with the obvious system losses in the overall energy equation. So clearly a net loss. But if you pump off peak, and run the hydro in peak it is a form of battery. The efficiency of that does seem challengeable, but it is how hydro works here. Well in the Snowy scheme, not sure whether they simply lose the water in Tasmania.

  2. Unfortunately, the economics would be horrendous. Pipelines are very expensive, and rarely make economic sense, even for oil which is thousands of times as valuable as water. And piping up and over a mountain would involve huge technical challenges and costs compared to on the flat, both in construction, and energy costs powering the pumps to lift the water upwards. And desalination plants only produce a small quantity, compared to rivers. So from a cost and engineering point of view, it would be a complete non-starter. Water is so heavy that lifting it requires a hell of a lot of energy. That's why we can extract so much electricity from the reverse process of letting it fall in hydro-electric schemes. Sending water up a mountain is the reverse of that.

  3. Mulberry tree are very fast and easy to propagate. If you just cut a 2 foot tip from the tree branch and pop it into a pot of soil, keep watered it will sprout roots very quickly and should bear fruit within its 1st year. They grow fast and are quite hardy. No rooting hormone or fancy magic needed for them. I have 8 started from before winter and every one has buds and roots come spring. Might help to keep the cutting out of very hot dry conditions for a few weeks. I've never tried such a huge branch, not needed, but you could try reducing that by half and giving it a try as well as the tips as an experiment. Younger, new wood should work better though and the speed of growth is very good. It helps if you strip all leaves except the those on the top tips of your cutting.

  7. OK, let me try again, from the beginning; Clearly Marx recognised that religion teaches contentment "the opiate of the people" and suggested that is a bad thing, as in it insidiously undermines society and promotes apathy in the face of a government that feeds off them. I disagree with his interpretation of what contentment, and by extention religion, means to society; it's certainly no stretch to say "Contented people = peaceful people" and if we extend the drug analogy, some drugs are more insidious than other's; for instance, a drunken bloke slam's down his pint and says "right, you're going down" because he doesn't agree with a perfectly reasonable thought; meanwhile a stoned bloke says "na, your alright mate, you wanna toke". Bearing in mind, how the Russian revolution worked out; was it better before or after, and for whom?
