Truly unbelieveable!! What perserverance. I can't imagine the time it took to complete this project. I would go to Home Depot to buy a generator!FWIW---Oldtommy
 
I installed a Turgo type Pelton wheel last summer, it produces about 30 amp from 100 feet head through one 3/8" and one 1/4" nozzle. Most power produced (during the course of a day) gets dumped, due to the batteries being fully charged.
Your plant seems MUCH bigger, how much power are you producing?
Do you Dump power or cut the water supply?
 
No way you could pull that off here. The pinko tree huggers/Gorons would shut you down in spite of the fact your going green if they got wind of it.
Definitely a cool project though.

Most of the components what we used came from Washington State.

I read he's producing about 5k watts, but he can ramp it easily up to 7, and even hit 10 - but that's the limit of what the system he's using can handle without overloading it.

I have to confess that part of what I liked about his success story, was just seeing someone apply that much of drive, determination, and ingenuity to getting "off the grid." That's a side interest of mine; not so much for eco reasons, but more for self-sufficiency reasons. If I ever do go that route here, it'll likely be using wind: that's the one resource we have in abundance almost year round. Alternatively, his approach is doable here too, but you'd have to build in the right place, and well outside the city. Solar isn't cost feasible here because of too much cloud cover and fog.

My grandparents (on one side, before my grandfather died of a stroke) lived entirely off the land, 18th century style: they used wood for heat exclusively that was cut and stockpiled in the summer, and similarly, all food consisted of that which they grew themselves, supplemented by hunting, trapping, and fishing. This was pre-confederation, and in the early days of it, when this was the norm here (and cash currency was a little possessed and rarely used item, with the barter system being the predominant means of exchange).

The 30amp we got was at 24v, which may not seem much, but over the course of a day has been sufficient. Solar is used in the summer and a Gen set in the mid seasons.
5 kw! seems overkill, unless he can sell the excess.

It sounds like a lot, but keeping in mind that a plug in kettle can use 1.5 kw, and that this is his only source of power, it really isn't. Appliances and electric heat can suck a lot of juice when they kick in. My fuse box is rated for 125 amps @ 120 volts, which would be 14.4 kw, and the heat here is oil so there is no electric heat drain on it either.

Of course, I use nowhere near that, but 5 kw seems reasonable when you allow for some extra capacity at the times the high current draining appliances are kicking in (perhaps at the same time).

If he uses A/C I would imagine he'd need a fair amount of juice for that alone, too, plus he isn't using it in conjunction with a battery system to supply any needed energy at peak consumption.

Edit: modern, higher efficiency appliances and such could reduce his energy needs too; but considering he is living in Chile, I imagine the stuff he's powering is fairly antique by our standards and very inefficient.

I agree with the rest of your post, but South America isn't just rainforest, natives, cocaine, and communists. It's pretty modern in many areas. I mean China is their vendor for everything, too!
 
I realized after I'd written that part, how it could be misread to imply I was making the exact impression you described.

When I wrote that I had in mind a contrast to the brand new "energy star" appliances that have been sold here for a few years, but are really still fairly novel here.

I inferred from the amount of pure manual labor used (whereas I would have paid a contractor to simply dig that trench with a dozer and it'd be done in less than a day), that he was likely a decade or 2 behind us in terms of his appliances.

Not meant to state they are "backward" or the like (his project proves the opposite), more that I was speaking to the technological lag that exists in Latin America and other parts of the world.

It was definitely not intended as any kind of backhanded or condescending remark. I think the guy brilliant not only in conceiving this project, but in pulling it off and in presenting it, at all of its stages of development, so well as he does.

Anyone who's going to go through all these to get electricity is doing it for fun rather than productivity and cost.

It would be a lot easier and more reliable to run its own generator or solar panel, or connect to the grid.

So, because it is a hobby that isn't cost effective, he would probably be able to afford the more efficient appliances, but the surges of voltage from his volatile source may damage the appliances quite often.
 
Its also a fairly recent lifestyle choice many are making in preference to be being held hostage to oil prices and utility companies (synonymous in many cases, as when one goes up the other tends to follow).

This is a philosophy I subscribe to as well, even though its going to be sometime in the future before I can implement it. It has not so much to do with the hobby aspect (a bonus, but not the incentive) and everything to do with a preference to get off the grid, and in that way at least, cease to be held hostage to the whims of utility boards and OPEC.

For these reasons, a generator is out - misses the point entirely.

Despite the initial high capital investment to implement it, the savings are easily realized when you amortize it over a 25 or 30 year period and compare that to what your utility costs would add up to over the same period, even assuming (falsely) that they will remain constant.

Its kind of its own movement. Some, as in this case, are simply retrofitting their existing premises; others are building from the ground up with a blueprint entailing no connection to the grid, and no need for one.

Google "getting off the grid" (and ignore the irrelevant hits that are bound to come up).

A bloke that I used to work with made a name for himself, and a fairly decent living IIRC putting in very simple hydro systems in PNG for remote villages, so that they had an extra couple of hours per day for education of their children.

He tried to bring it back here, and it's pretty woeful as a concept to make even a few hundred Kw tied into the grid...but the easiest system is a squirrel cage operated over synchronous tied to the grid.

Synchronous off grid needs some thinking.

As to a previous "energy invested" comment, yep, there most certainly is...a lot less than building a power line usually (many solar systems are too), and the free market don't seem to be knocking at a lot of people's doors.
