Greeting to all, I think it has been nearly 3 weeks since messages have been posted to SWIEP. Two weeks ago I presented a 1-h talk about my Net-Zero Energy...
Hi all, TIMAPE part 4 is now available for download on http://www.ualberta.ca/~mtyree/SWIEP/Publications.html . Download R#36 at the bottom of the page. TIMAPE...
Ted, Thanks very much for your message. I hope you do not mind that I make it public on my SWIEP site. I would very much like to see a draft of your MSc thesis...
Hi All, Before customers get too excited about the potential of power production from small wind turbines mounted on a roof in an urban area, PLEASE take a...
Matt, I agree that if a buyer wants to know the wind energy potential it needs to be measured on site. The problem is that the cost of this assessment can be a...
Hi all, I'm new to the group and pretty new to wind turbines. I looked at the Warwick studies and all I thought I saw were references to HAWTs. Did I miss...
Jerry, Yes, you are right. But both VAWT and HAWT are limited by the wind resource. My idea is that urban sites reduce the wind resource and mounting any...
Gotta agree that seems reasonable enough. That's one reason why I went ahead and put up an anemometer (even though it's not at proper altitude)--it gives me...
Hi Ted, Call me Mel; I don't like formalities but use my titles regularly because I think doing so sometimes draws responses from people who do not know me who...
Thanks Geoff, I will cut and paste your suggestions and post it on http://www.ualberta.ca/~mtyree/SWIEP/Publications.html So that other people can look at your...
Roger, Thanks for your comments - VERY WELL STATED, but not the first time I have seen similar statement. I have included your quote below together with Geoff...
Gents- Studies were performed 20+ years ago exploring urban windmill feasibility; generally the turbulence argued against exploiting the resource. I believe a...
Thanks for that Mel, and I find difficulties with Yahoo groups also. Cheers, Geoff....

Hi all, Just before heading off to an NREL conference, I thought I would post a few critical comments about a recent article published in Home Power Magazine...
Hey Matt. I would approach it the other way. If a site assessment indicates a good resource, then when I put in the turbine I would by the APRS system and...

Yes, but I beg to differ with you on the value (or lack of it) when dealing with turbines that will cost the consumer > a certain Dollar amount. The amount of...

Geeze, Roger - It's the chicken and the egg debate all over again! How does one get the site assessment sans anemometer? Out here in the gol durn West, it's...

Ah Grasshopper, you must seek the source of wind energy site assessment training and you will come to know how that works without an anemometer….The ...

Since it doesn't include certification for anywhere West of Colorado, we obviously have different types of wind out here, that they don't know how to explain....

I agree with both of you. Now, we need an economist to calculate the cross over point to make it feasible to conduct a full wind study. Ed...

The economist chosen to do something like that will have to do a lot of considering! What is really expensive for one person can be completely the other way...

Hi all, Last week I posted an Opinion Paper in response to a Home Power Magazine article written by Dr. Brian Raichle and Brent Summerville about the economics...
Hi Mel, I share your doubts about the ever increasing tower height as a way to maximize the energy capture of small wind turbines. The tower height is...

Hi Paul, I am not sure you understood my current view. I am agreeing with the authors of the HPM article. Spending more on tower hight does pay for itself...
We will announce by December a doubling of power output by increasing the diameter of our Windspire from 48 inches to 96 inches from the same 1.2 kW system...
Hi all, The Xantrex-built grid-tied GridTek10 inverter sold with the 10 kW Bergey turbine is poorly designed. Under windy conditions, it is prone to bus...
Pretty neat Mel....thank you! Seems like this would be a natural for them to just add this, don't it? Steve ... From: Tyree, Mel To: SWIEP@yahoogroups.com ;...
What is the future of electricity? Can we develop alternative electrical power sources? When the future of electricity is discussed, quite a number of thoughts...
