Wind Turbine filmed for national TV

Being Aired on Friday 23rd January

RTE TV “Nationwide” contacted us about our successful week-long course with Hugh Piggott in September. To film our grass-roots work for a new ecological feature starting Jan/Feb 2009. Niall Martin (Producer) and Enda O’Brien (Camera) were so professional that everyone relaxed within a few minutes and filming went pretty smoothly.

Crann Og Turbine


Hugh Piggott Workshop 2009

How to build a wind turbine A workshop course with Hugh Piggott
at Crann Og, Gort, Co Galway, 7th – 12th September 2009

After a very successful workshop at Crann Og in 2008 Hugh Piggott, was here for another wind turbine building course.

Hugh Piggott, designer, author and world renowned expert on wind power, is leading a six day course in which the participants learn as much as they are personally capable of learning about small wind turbine design and construction. Hugh’s workshop courses take place around the globe. It is a wonderful opportunity to learn hands-on skills and really take part in building a wind-turbine with the guidance and experience of a great teacher. Visit Hugh’s web site at

The Workshop:
Each day, a modest amount of theoretical introduction will lead to workshop sessions with opportunities to gain hands-on experience of carving wooden blades, winding coils and fitting magnets into purpose built alternators for windpower, wiring, fabrication, erection and all aspects which can be covered as time allows. Participants who bring their own ideas and materials to the course will be welcomed and given assistance where possible.
Where participants have brought the materials, they will be able to take the complete (or partially complete) components (blades’ alternators etc.) home with them.

The purpose:
The Build Your Own Wind Turbineā€ workshop course is designed to inspire, empower and inform participants who wish to build small wind turbines; to cater for people from all backgrounds, age-groups, nationalities and educational levels; to provide some basic theoretical understanding, and to develop the necessary workshop skills and confidence to enable participants to undertake small wind turbine construction projects safely. Previous workshop experience and/or knowledge of tools is an advantage but is by no means necessary, relevant workshop skills will be taught at whatever level is required and everyone works at their own pace. Participants are encouraged to take part in all the various workshop activities, whatever their level of experience, this leads to a better understanding of all the processes.

Balancing the blades in Gort

We were back in Gort on Tuesday 4th of November to balance the blades and install the dumpload.

The balance was out a bit you could tell by the shaking of the guy wires and the tail. The day was nice and calm and we lowered the turbine down so that the blades just cleared the ground and we got it done in no time so she is now balanced nicely.



We spotted two problems. On the front triangle of plywood the paint has bubbled around the edges where the screws are and it dos not look like marine ply as the wood is also starting to separate the paint is top quality marine stuff and put on by a pro (Flor) so that is not the problem he sanded it a bit and put on some varnish to try and seal it. And there is a little crack on the back of one blade probably caused by a plane or spoke shave going against the grain not serious though we put some glue on it.



We decided to leave the replacement of the triangle until September and also the blade to see how it all wears but if it looks bad we will do it before that.

The resistors for the dumpload finally arrived six 3.1 ohm 300w wired in parallel and I bent some metal and mounted a slate on the wall behind it so it should be ok it pulled 43a and got nice and hot so the dogs will be happy on stormy winter nights.



The best power we seen was 42a in a strong wind and dipping down to 18a. All the lights and some sockets are running of it nice and easy and now that all the bulbs are cfls so next visit we will wire all the house except the freezer and dryer looks like they are heading for an off grid house.

Putting It All Back Together

Hi folks, we were back Crann Og today, Saturday October 18, full crew consisted of Flor and Marion, Dinger, Sean, Niall, Jimmy and Miriam. After a lazy breakfast we set about putting things back together, having first admired the great paint job that Flor did. First was the new bearing and then fitting the stator and rotors, using the jacking screws to lower the rotor and ensuring that all the gaps are even.

Next we brought the blades back outside to put them together, using the identification marks to ensure that the blades were in the right order with each other. Dinger and Flor went around with the tape measure until we had the required distance between the tips and then it was out with battery screwdrivers, three of them, to fix the blades in place.

Back into the workshop to fix the tail to the tail frame and then after a coffee break it was time to bring everything into the field, using the tractor again to carry the alternator. It seemed easier this time round to fix the body of the turbine to the mast, using a little gentle persuasion (a 2×3) and then fix the blades, Niall measured the blade tips from the horizontal to ensure the best position.

Dinger and Jimmy raised the mast and the colours looked great even in the cloudy conditions, all went smoothly and she was spinning as soon as the brake was thrown, sounding lovely, a gentle roar when the wind picked up.

Tomorrow we are expecting winds up to 110kmph! That should test her out – the tirfor is still attached so there might be a pyjama party in the field if the winds come earlier and heavier than expected!

We’ll let ye know…

Update 25/10/08
Surviving well and producing plenty of power we are going back in a week or so and will give a full report then.
