Been hard at work again building something new and interesting. We've had a few different versions of this design and are finally up to the stage of testing a working model. It has taken a while to do the dead work of trying different Darrieus designs and have finally got one that actually generated power even if it is a few hundred watts. Sure, there are still a few hiccups. It sure is good to find a new challenge.
Background: We needed to find a location to set up a permanent 2kW turbine for performance monitoring, and we decided to help out our friend Scott. He desperately needed to save money on his electricity bill due to all his wild parties.
Design: An alternate design had to be approached, so we decided to construct a prototype 2kW Vertical Axis Wind Turbine (VAWT) using a straight blade Darrieus design. The Darrieus vertical axis windmill was patented in 1927 by the French Inventor Georges Darrieus and is a lesser known alternative to the typical 3 bladed HAWT
Do you guys have any comments? (apart from 'yeah, your blade fell off')
