We used local pine wood for the blades, some knots however pretty good wood for carving.Wind-Turbine-Workshop-Braganca-portugal-09Rotor timeWind-Turbine-Workshop-Braganca-portugal-11Soldering the coilsWind-Turbine-Workshop-Braganca-portugal-12Getting the moulds readyWind-Turbine-Workshop-Braganca-portugal-10Cutting out the islandsWind-Turbine-Workshop-Braganca-portugal-13Wind-Turbine-Workshop-Braganca-portugal-14Action stations!Wind-Turbine-Workshop-Braganca-portugal-15Wind-Turbine-Workshop-Braganca-portugal-16Placing the coils in the mould, some resin is already in the mouldWind-Turbine-Workshop-Braganca-portugal-17Pouring the resinWind-Turbine-Workshop-Braganca-portugal-18The blades are getting nicely carved downWind-Turbine-Workshop-Braganca-portugal-19The paparazzi have found us again – RTP, one of Portugal’s four tv stations came to have a chat with the workshop participantsWind-Turbine-Workshop-Braganca-portugal-20Wind-Turbine-Workshop-Braganca-portugal-21You can see the flock of sheep grazing in the background, ironically near the garden bar-b-que.

4.8m wind turbine update

We ran a Build Your Own Wind Turbine workshop in 2009 where we built a 4.8m wind turbine. Now after four years it looks like the turbine might be flying in the new year. The mast has been made and the steel is undercoated. Next big job is to get the mast up the hill and that will be quite an undertaking. Another job is to wind new coils for the alternator, the coils were originally wound for a battery system (24vDC) however now the turbine is to be grid connected so it needs new windings in the alternator.

Presidential visit to Lough Graney Youth Club in flagmount Co Clare

The President of Ireland Michael D Higgins unveiled a plaque for the ‘Tree of Generations’ sculpture made by Lough Graney Youth Club.
Tree of Generations' sculptureOur involvement was working with the Youth Club to explain how the small wind turbine works. First they wound the copper coils for the alternator, they painted the blades, then they designed and painted the beautiful Peppa Pig tail. The turbine is a Hugh Piggott design 1200mm and charges a small battery with the help of a little PV panel and a few LED lights are run off the system.
