Some of you might remember that a group of us are working to design and build a smalll vertical axis wind turbine. One of the great things about working for a product design and innovation firm is the level of resoures at our disposal – both physical and intellectual. Is there anything these folks can’t do?
The ultimate objective would be to disconnect my office computer, lights, etc from the electrical grid and see if we can be a president who is… well… err… disconnected, I guess. Hmmm. Maybe I should think about that a bit.
Anyway, we reached a milestone of sorts after the weekend when our prototype made electricity for the first time. The turbine was designed and built entirely here at Design Concepts including CNC foam cutting of the blades which you can see here: http://www.design-concepts.com/blog/hot-wire-foam-cutter-for-our-wind-turbine-project
My sincere thanks to Design Concepts’ electrical engineer extraordinaire Chris Sherwin for his slick prototype charging circuit. Chris has a passion for power supplies and charging circuits and whipped together a design which handles cut-in, voltage step-up and even has electric braking! Not bad for a first generation.
We have a way to go, but it’s been a fun diversion.
