Small wind turbine workshop in Belgium with Tripalium Jay Hudnall

Wind turbine construction workshop course at Périple en la Demeure in Belgium with Jay Hudnall of Tripalium / Ti’eole and Vincent Judalet from ÉolSenegal.   Périple D is both a school and a brewery – a good combination for our purposes.

Jay brought a completed 3.6 metre grid tied machine (SMA 1700 inverter), and we built a 2.4 diameter battery charger (24V) Also Davide brought a 1.2 diameter, 12V turbine for overhaul. The 3.6 got erected on the Wednesday morning and we swapped it for the 2.4 on Friday morning.  Not a great wind site, but both ran nicely and produced energy.

We balanced the blades of the 2.4 on a spike, which worked very well, so there was nothing left to do when we put them on the turbine really.  Two blades weighed 1.4kg each and one weighed 800 grams.  Red cedar.

There are some glimpses in the video of a stator made by Nicolas Delhez of the organisation Atoutvent in Belgium.

The thin overlapping coils make a very efficient use of the space.  But it was a lot of work.  We were honoured by a visit from Nicolas, who showed us his fibreglass blades and some photos of machines of up to 12 metres diameter built by members of the association.

About hugh

I live off-grid in NW Scotland and have spent my life playing with wind turbines. I also love small hydros. Hands on renewable energy is my thing and I like to learn and to share my experiences.

    I suggest that anyone wanting to discuss this with Nicolas contact me for his email address or visit the web site Atoutvent

    Another interesting stator making process can be seen in the photos at

    They make each phase as one big coil around the stator and then shape it to zig-zag in and out of the magnet paths before pressing it into a shape similar to the one seen above.

    Ultimately this sort of stator seems to lose out by making the wires too long and by being laborious but it’s interesting!

    This is very Interesting approach. Do you have some more information. On this thin coil generator design?
