I’ve always been a proponent of self-sufficiency. Because of this, I’m fascinated by alternative energy technology. This is a vertical axis wind turbine made of cardstock. Why? Because I wanted to see if I could. I can. It’s mounted on a cardboard test tube here, but when hooked up to a DC Dremel, it generates a few millivolts at about 8mph. I would like to make a larger one out of Dr Pepper cans. A sectional chart provides a nice backdrop, and to the left is a model rocket.
