It’s been a long time since I’ve made an update; it’s time to get back in the habit. We had a whirlwind weekend finishing up one of our solar installations and our shed project. Here’s a picture of the shed and I’ll hopefully add some of the solar installs soon.

I lost my Grandmother on my Mother’s side April 3rd 2008, Barbara Gullage. I was the youngest grand-child in the family and when they tried to teach me to say Gramma and Grampa, I could only ever come out with Amma and Papa. Well, it stuck and that is what they were called by most in the family. I’m going to try and get a picture gallery setup, but until I can I felt the need to put something up. There was a recording she made before her 70th birthday and we were able to capture her funeral service.

 Just thought I would post something to compare against to show how brilliant the colors are. Clearly this was before the grass really took and it's a little different angle. |

 Well, fall is here and it has been beautiful. I'm working on a number of posts to catch up on all the goings on, but Elaina just sent me this link and I wanted to get it out. Life is going well and we're still alive, just too busy for more frequent updates. (Click on the image to go to the yankeemagazine.com page.)

Lakota Turbine is Flying! |

 Wow, there have been a lot of serious accomplishments since the last update. First and foremost the Lakota wind turbine has finally been installed and has been producing power for the last 3 days. Not a lot of power, but it does get going during steady breezes (movie!). We saw it spin up a few hours each day for 9 out of the first 10 days.
This turbine is rated at 900 watts but in extreme wind, wired properly people have seen spikes over 1500 watts! We don't have any wind measuring equipment at the top of the tower so we can't give quantitative analysis but we see a few amps (under 100 watts) in a light wind and have seen over 10 amps (over 250 watts) in a moderate wind. I believe the major limiting factor at this point is the fact that we purchased a 48 volt turbine because we planned to eventually upgrade to a 48 volt system.
What is happening now is the turbine spins up to the point where the 24 volt battery bank provides resistance and that stalls the blades at about half the speed (RPM) it generates power most effectively. Just like a car alternator, power generation is very poor at lower than designed RPM. Hopefully we'll see a 2x increase in power from the same wind at the new battery voltage and I don't think it's unrealistic to hope for 4x.
Now that we have the turbine up and running, we've prioritized the purchase of the new equipment to get us to 48 volt! Stay tuned for the pictures and review of the new equipment. |
