The site of the new wind farm is in Ayrshire, Scotland. The farmhouse we've just bought is going to have one wind farm behind and one in front. A few miles...
Just got the magnet "flywheel" formed up, just using 16 ga steel with a lip formed on the edge to kinda keep the magnets from flying off ( I Hope). Formed...
Phooey, mounted the magnets, spun the flywheel in the drill press at low speed, single coil of 200 turns, about .9 volts ac with no load. Wonder what I can...
We have tested the AWP for six months on the SEPEN test Centre in Narbonne (south of France). The test site is a tough one with gusts up to 30 m/s at least...
Hi Darryl, I had a question regarding the "special care" for the house and heat source field you mentioned. What exactly to you mean by that? Where are you...
HI Hugh as you know I have worked on a couple of MPPTs, this time I am working a manufacture. I do not think we will be ready in time to test for your MPPT...
... run on electricity supplied by the grid doesn't really reduce emissions over that of Nat.Gas. much. But coupled with a carbon neutral elect. energy source...

Hi Donna Do you mean geothermal or ground source heat pump? Best wishes, Jim Jim Barr http://homepage.ntlworld.com/wandana/ Best is the enemy of good enough ...
Did a better setup on the drill press, closest I can run the magnets is about 1/16" ( got a bit of wobble). St the slowest speed, output of 2 1/2 volts ac...
... Yes, the blades produced by AWP in the last few years have the wrong tip pitch and are rather noisy. It took several years before I found out about this!...
Got a test setup on my little alt. using 6 magnets on a 6" plate for the rotor, wound 3 coils, each puts out about 1 volt running at slow speed on the drill...
You are right on the point Joe! Improved efficiency in machines and buildings Conservation Recycling These are the basic steps for a meaningful energy policy. ...

Hi Darryl, Let's not forget to mention that a voltage limiting device is required to protect all of these controllers from anything >150 VDC; otherwise you can...
... With the magnets laid on looks pretty cute. ... I would suggest to epoxie the magnets on for your test ... Spin the magnets up and short the winding leads...

Hi Paul, I always advise Tubular Positive batteries for wind or solar systems, there is an article on my web site, http://www.iig.com.au/wind/batteries.html ...

We are particularly interested in VAWT type of wind energy. Namely for Tract housing or small (small) business. Do you have an opinion on this type unit. ...

Dear David, even though it's well known that this group is inveterated HAWT confirmed and every mention of VAWT leads to a big "howl" ;) I suggest to visit: ...

Hi Matt, It sounds as if you may have tried this already. I replied directly to Darryl with some details but it would probably be more productive if he did...
... There we go! Total and complete agreement! Well done! I'd even go so far as to say I'm shocked that it works AT ALL with non-photovoltaic applications. ......
