Add that in, and the cost of a $15000 system is much worse - over 30,000 in a 25 year, 7% mortgage. You have to take into account that the cost of a kWh from the grid in 25 years will be a LOT higher too, if there still is a grid during and after WW3 that is. That's silly economics. I do not have to take into account the cost of electricity in 25 years. I can wait. Solar cells are becoming cheaper too. When the cost of the solar cell is less than the cost of power from the grid I can switch, saving all of the negative amortization inbetween, and have a *new* system in 25 years, just as you're in need of replacing yours. ;-) My guess though, is that solar cells for the individual will never become cheaper than power from the grid, since the power company has access to the same technology and a *lot* better financing possibilities. ...and they don't have to have the pay- back in my lifetime. They have access to the tech, BUT, they also have to maintain the distribution system. Since my electricity has been unbundled, roughly half of my cost per Kwh goes to the distribution co., not the producer. Ice storms, drunk drivers, blown line fuses all cost money. As well as the personel and associated benefits packages, transportation costs of materials, etc. for maintaining the lines. All this is avoided cost on home solar. And... www.solaraccess.com/news/story?storyid=6482 talking about a new discovery: "A solar cell with the simplest possible physical structure could achieve 50 percent efficiency or better, far higher than any yet demonstrated in the laboratory." It isn't cost effective for most of us yet, but the tipping point is coming. -- Jerry wa2rkn no email @ present |

It's an unusual place- the wind just whistles through the canyons there and there are dust stoms. A fair number of them seem to be down for maintenance whenever I go through. I wonder if it is really more cost effective than burning coal. That depends to some degree what you consider the "costs" of burning coal are. I think, other than the pollution, the costs are included in the overall running cost (dead miners, etc. etc.). The pollution is a bit harder to figure, but modern plants are pretty clean. I live close to a big thermal plant and the left-wing newspapers have been running pictures of the stacks (usually with evil lighting) saying that "smoke" is rising blah blah. They've dug up old pictures with all 4 stacks running, and it's usually running at 25%; never more than 50%. Of course it's mostly steam and some CO2- on a clear day you can see nothing in the air discoloring it, just the refraction from the heat and steam trails that rapidly dissipate. The stupid new gov't has been making noises about closing the thermal plants *AND* the nuclear plants- I don't know where they think the power would come from (maybe we can buy it all and export the problem to less "responsible" people). Bleh. Even with conservation measures and some deindustrialization, population is growing at a healthy rate, and so is consumption. I assume you are talking about coal fired plants? They release particles as well as mercury and radioactivity. There is no clean power. -- Jerry wa2rkn no email @ present |

Highland Ham wrote...
Having seen these machines near Palm Springs, they seem to be rather small and of an older design. I wonder if they shouldn't be replaced, that's prime wind territory. In the Netherlands many farmers have them on their land, especially in the northern provinces. Do they rent the space to the wind-generator owners, or do they each install and maintain them themselves? Is there a subsidized rate for the sale of electricity to the grid? Thanks, - Win whill_at_picovolt-dot-com |

Roger has been listening to those who have a nice tidy explanation of
everything. Sometime you want to try to explain to him how come our lettuce is so cheap. "Roger Gt" wrote in message . com... .... Is that why 18% of inmates in the Oregon prison system are illegals? Nearly one third of petty criminals in Southern Ca are also illegals. Actually, this probably has more to do with the great public defender they are likely to get. You haven't got the perspective! The sleep on the streets and hang out at businesses hoping to be offered work and have destroyed whole neighborhoods. Well, I lived down in Orange County CA for a long time. I must admit that there are some offensive things going on, but most of the illegals I know about are not the quintessential Hobos of our modern society. Too much risk in coming above "the man's" radar. They hang with their extended families, and out in the farming districts where they get seasonal work. Big population in Colorado for some reason. The problem is spreading and it is really bad the nearer you get to the boarder. Farmers along the border have their crops and equipment stolen or spoiled and have to maintain a security patrol to keep their homes from being broken into. These people are criminals and do not respect any laws. Beg pardon. These people, except for course for the drug mules that we pay to bring us our cheap drugs, are the brightest, best, and most ambitious of a seriously abused population. We might solve 90% of our problems, at the cost of a bit more expensive lettuce, by making them semi legals and preventing their abuse. .... (subject. Paying taxes.) Not then, nor now! They are a major burden on the state to the tune of about $4b a year! Whew! Is that all? They are responsible for around 12 billion in company proffits, of which they get around 3 billion, and out of that they pay around half billion in sales taxes. Actually I expect their employers collect federal and state tax from their salary, and pay it to themselves. I think that overall our illegal emegrants likely provide us more benifit than cost, and on top of that they are such an easy target for racial and cultural hatred. Easy to blame our total failure to provide for our own poor by calling them all illegals because some few are, horror of horrors, unable to get legally admitted to our official version of heaven. BTB, I just made up the numbers for the heck of it. Sounds reasonable to me, so find better ones. |

On a sunny day (Sun, 18 Apr 2004 09:20:33 +0100) it happened "Highland Ham"
wrote in rSCgc.657$Gq3.274@newsfe1-win: Now a wind generator would be cool, there are many windmils of huge size here, one next to my house (100m or so), a BIG one that replaced 5 smaller ones... It is on the coast, and it is always windy here... How big is that thing? JP ============================== As I reported in a previous message its rated capacity is only 150 Watts. 6 Blades , 900 mm diameter, max rpm approx 250 , 3 phase generator ( DC through one and a half standard 25 Amperes bridge rectifiers) The thing sits on a street lamp post with an extension (approx 8 metres above ground. Frank GM0CSZ / KN6WH Thx, sounds good. I have a place for such a thing, and 1 meter diameter is not much. Will think about this a bit :-) JP |
