Hi all, I completed construction my Net-Zero Energy House in Jan 2008. The house is net-metered and powered by a 10 kW turbine + a 10 kW PV array producing...
Steve, How is your house in Colorado progressing? I think you are building it now, right? I think your house will be off-grid. If my memory is correct that...
Hi, SWIEP has reached a milestone...100 members. I was just about to mark that occasion two days ago but one member dropped out so we were back to 99 before I...
Hi Ellen, I do remember you and that you want to install a ReDriven turbine. Has NYSERDA approved funding for this turbine? Or is that decision what you are...
There seems to be a wide variety of data on wind in a particular area - the wind map used by NREL and the map published by 3Tier are widely different. Data...
Steve, I watched the video, but I couldn't find the photos about the turbine building project. Can you give a more exact link? --Mel Mel Tyree, BA PhD...
I'm uploading them as we type. Will be ready in a few minutes. http://www.green-trust.org/DIY%20Wind%20Turbine/ Steve Spence Renewable energy and self...
Hi everyone, I have completed a little study of BWC's new PowerSyncII inverter. This study compares the PowerSyncII efficiency to the GridTek10. Next on my...
Tod, You have inspired me to check my readings again, but it will be a be a couple of months before I get back to that inverter to check again. I will be...
Tod Hanley kindly gave us all data on another PowerSyncII inverter in tabular form (on s-w-h). So I added these data to my report(Figure 1). He is showing much...
Re: Doug's account below: This is a very useful story. To this list of "reliable turbines" (based on long experience) I think we can add the Jacobs. Jacobs ...
Doug, Sorry, I didn't notice your message, but Nando answered you; it is a job for the manufacturer. An automatic reset is not a science problems. The science...
Mike, Thanks for explaining in more detail. I wanted to write a brief message so did not go into all the details.I was trying to counter Doug's statement that...
Hi all, I use clock-timers to measure wind speeds. Clock-timers are very precise except at low wind speeds, when false triggers of the clock-timer circuit can...

Here is some interesting customer feedback that is new to me concerning an ARE turbine. Hi Jimmer, Are you able to get your system manuals into pdf format?...
This gets me 30% more energy than I actually get on my turbines...????? Mike From: SWIEP@yahoogroups.com [mailto:SWIEP@yahoogroups.com] On Behalf Of sspence65...
What variables did you use? It was spot on for my AIR X. Maybe I screwed up a formula somewhere. Steve Spence Renewable energy and self sufficiency ...
It is not designed to do a VAWT…. radius is 2 feet on ours, that is not enough to give a swept area on a VAWT. That gives 300 kWh – 20 feet is not right...
No, it's not designed for VAWT's. Steve Spence Renewable energy and self sufficiency http://www.green-trust.org http://makingthewebwork.blogspot.com/...
I just put the finishing touches on the new air density calculators, associated with the wind power output calculator. Please test and advise. The calculator...
I'm starting the design of a fair sized VAWT turbine (~10' tall). I'm having trouble finding a decent drawing to scale my design. The turbine type I'm...
If you don't even have a decent drawing, then why do you think you want a VAWT? Maybe you should backtrack and first try to get more information on the...
Hello I'm a new member living off grid since 83 and have been looking at wind turbines as an adjunct to our pv system which is a little shy of 1kw. The one in...
