I think its sand, but I'm not sure. Hi Antero, welcome to the site. Let us know how the Exmork wind turbines go? It will be interesting to see how they last compared to the Bergy. Glenn The best time to plant a tree was twenty years ago, the second best time is right now. JAQ |

I think the problem with many commercial wind generators is they are virtually hand made. With little or no economies of scale. Really the technology involved in a wind generator is mature enough that there is no resion why they could not be mass produced like TV sets or washing machines. But what is the market for them? |

anteror On a more serious note: Thanks for the pictures; nice work. I hail from southern California and it's nearly-perfect weather here year round. We actually pay money just to visit the snow! You've come to the right place. Many of us here, myself included, are of the idea that technology is something to be shared and not hoarded. Anything I post here is offered free for the taking and I think that holds true for the rest of the crew too. It boils down to greed. Everyone who has ever visited my home machine shop usually says right off the bat, "You should patent this stuff!" Their idea is that I should hoard the ideas and charge folks for sharing them. My own intentions here are to build workable alternative energy projects that anyone can make in their home shop. I learned one of life's greatest lessons in kindergarten and that was that we "share" the big wooden blocks. I also learned that there's absolutely nothing that can't be sorted out over graham crackers, a cup of milk and a little nap! Nothing difficult is ever easy!

well the manufacturers arnt going to like you much then Antero.... 
great testing ,thanks for sharing ...can i ask ,does the exmork have a furling tail ? i had a futurenergy for ...erm...1 day... before i took it down...the alt seemed ok....just kind of mismatched to the prop and tail niall |

Hi Antero, I think what you have said is constructive criticism. The manufacturers will construct something new from your criticism. My windmills do not stop long enough for birds to stop and perch. I have never seen a dead bird under my mills either, and there are many wattle birds, honeyeaters, starlings, crows, seagulls, swallows, parrots, etc that fly past. Gordon. become more energy aware |

There should be obligatory classification and certification to all small windgenerators before they are allowed to been sold. As soon as possible. Antero |

There should be more tests like this one; http://www.lowtechmagazine.com/2009/04/small-windmills-test - results.html and more talk like this; http://www.fieldlines.com/story/2009/8/31/183217/142 and http://www.scoraigwind.com/rooftop.html I repeat that it is shamefull, that people who CARE and want unpolluted energy, are been misguided. The whole very good idea of having own unpolluted energy via wind, will crunch to stones, if there is not change for unrealistic promises and allso prices of the wind generators. Antero Finland |

Thank you for the link Anteror. I finally read it today, and the comparison really puts those little guys in their place. Especially when compared to the 18m turbine nearby! 37,000 Euro for a WRE that produces less than 500 kWhr. That is 74 EUR per kWhr per year. The pay-back time for that is "never". To extend the comparison to my home-made wind turbine, it had a diameter just under 2.5 meters, and I estimate that it collected between 400 and 500 kWhr last year. That puts it on a par with the tests in the Dutch study, but I paid MUCH less money for my scavenged parts and raw materials! Steven T. Fahey |

[quote] I have used 1.10-29.10 319 kwhr, which is all produced via wind ! Exmork 2kw is working good, producing 2 times more energy than Bergey. [/quote] This is what counts.... real world usage figures. Thanks for the story Antero ..........oztules Village idiot...or... just another hack out of his depth |

Hi anteror, Nice battery setup. I am trialling a small LiPo [24V] installation. Those NiCd batteries can supply serious current. Phillm has a smaller pack. Have you had any problems with reduced capacity over time. Looks like you have an average 10kWhr per day. This is quite high for an RE setup. My windmill has produced 5kWhr in a day, but averages around 1kWhr. What is the daily range of power produced within the month? Gordon. become more energy aware |

Hi antero, I have AxFx alternators of my own design, described elsewhere on this forum, with custom yaw box with slip rings. Mills are 8m to top of blades. Council restrictions. 2000Ah! Most RE owners would be envious. Gordon. become more energy aware |

First: you live in a beautiful place! I am also very impressed that with two wind turbines you are able to produce an ample supply of power. That must be an excellent site for wind, and you might want to keep it a secret for a little longer... Your consumption of power in October is equal to mine in the summer. My high winter consumption, and lower local wind speeds, would make it difficult to afford wind power here. Building it myself takes the cost a long way down, but I can't rely on professional service when things go wrong, if you know what I mean. Steven T. Fahey |
