 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Lloyd, I'm sure the price will go down. Input costs were so high, that price does not like me either. But the first alternator was sold before being finished :-) People are afraid of the future ...? Miro http://www.vawt.om2cm.sk |

Actually when you consider the time spent developing thes things you have to sell them for ten years to get your money back. But your time is worth nothing, right? :<( At least that's what my customers seem to feel about mine. Good to hear about the line up of customers  , because the product is good you should have no problem selling a bunch.

Hello Miro, I am trying to figure out if there is anything different from the standard axial flux design as presented by Hugh or the Dan's on the otherpower website. It looks like mine give or take a few changes and your coils have more winding to accommodate a lower cut-in voltage but you pay for that with higher stator resistance. Is there anything different? THe cost seems very high for a 1 kW AX-FX design. I must say that your coils are about the best I have ever seen. Very tidy indeed. Perry |

Hi Lloyd, I have selected 2 points from one of your previous posts. I am not missing a "1" from the rpm I quoted. It is actually possible to produce 1000W from a HAWT, spinning at only 175rpm. I am not really sure if there is a place for any windmill that spins to 3000rpm. I live in a residential area and my windmills are not silent, however they are very quiet and are an asset according to my neighbours and other town residents. I notice alternator whir on my smaller windmill and a dull alternator hum on the larger windmill. The birds and rustle of trees and local car traffic are more noisy than the windmills. I am sure that once you have made your own alternator and proceed through some more testing that you will recognize the validity of some of the data that has been presented here before implying it is an order of magnitude in error.. Gordon. become more energy aware |

Hi Perry, Yes, coils are beautiful, they did a specialist firm on the exact assignment. The coils are perfect. Of course also have isolation between layers, with a special very resistant tape. Otherwise, not much difference from traditional AX-FX. Perhaps only the shape of the coils, which seeks to exploit the full coverage of one coil with two opposing magnets in the same time. Just what offers the system x-coils, y +(1 / 3)x magnets. Details as at this page Something else. Alternator may have a power of 1 kW with the use of VAWT. When used with HAWT can be done about 1,5 - 2 kW .... Miro http://www.vawt.om2cm.sk |

I just didn't follow the logic of the 100rpm producing 20w and the 175 rpm producing 1000w. That's why I thought you left a 1 off the front because 1175rpm is quite acheiveble with a 10ft. span. Not that you want to run at that speed, or any particular speed. I would not want my hawt to run that slow though; 100-175 unless I had a 7-9 blade configuration or one of the old water pumps or a geared up system, and I think that is the only way you could get that curve. Why don't you tell me about the configuration of your setup so we can get rid of the apples and oranges and tell me how it all works together. A message to all offending parties : I don't know what you guys are trying to prove by constantly demanding I post data That I already have, in spite of the name and the vein Of this post. Like I said: Lets just see how lenient you guys are when this happens on your thread. I have never seen such a diatrade against some one saying this is something I am working on, show me yours. Your comments are not constructive or supportive when they are couched in the veiled insults and jabs that have been common since I posted this thread. I look forward to all and any comments but don't get all broken up when your lack of civility pushes me over the edge and I start to give back. Lloyd |

Hey Lloyd, Sorry if my request for data was misconstrued. Speaking solely for myself I can say exactly why I requested data. What you showed was different than what I usually work on. I see it spinning so it has passed the first hurdle in my mind. The next logical progression is 'how well does it work?' Seems like an obvious question and is how anyone would decide whether further investigation is warranted or not. Data is the universal, unbiased gate keeper on such decisions and most people here share it. Simple as that. Perry |

Hi Perry, sorry for the delay in answering but if you look at the labelling of this thread, it is constantly getting hijacked by the incessant demands for output data which I have in the beginning been quite civil in answering until the tone; and direction, of the discussion became what it is. When I posted this thread I wanted; as you can deduce from the title "lets see yours" to see pictures of every ones mills flying, big and small, of every type and configuration, and no discrimination about whether it is flat, round, sideways, in air or water intended, and no questions asked about what or whether there was any actual power output or intended; maybe it is some kind of weird; different, configuration no-one has thought of before. From here you could; if you were actually interested, start a thread, discussing the particulars of the unit. most people that come on these forums know how much of an insult this continual hijacking is and so the intentional nature can not be hidden. I'm shutting this thread down in my mind as there is no signifigant contribution other than the odd post that deals with the thread label. the unit pictured was all I had available at the time and in other posts it was discussed what the nature of the design and parameters were. I have an alt now so will be putting this style of wing on it and getting some data in the future which I will have an "Appropriately" labelled thread for. Thank you all for the "on subject" posts. Lloyd |
