there is no explanation, but this video does visually illustrate the basic principles of VAWT design and construction.
This is just one example of how PVC can be used as a prototyping material for robot designers.
Vertical Axis Wind Turbines take less horizontal space to operate, and they don't have to face any certain direction to work. Larger turbines are absolutely beautiful.
It is so easy that there's a kid showing how to do it. This pump can mean the difference between water and no water in some places.
Oh, yeah. I was a skeptic, too. A few things are worth noting, though. 1) This stuff is cheap. You can get started on a project for very little money. Even advanced fabrication tools are reasonably priced.
This guy has some great ideas, from planters to storage containers.
10 self-explanatory project ideas you can expand on to bring your kids fun for less!
This was done by heating up the entire pipe, cutting the sections lengthwise, turning them inside out and tying them into crazy shapes.
I've been hell-bent on complete self sufficiency for a long time now. There was a point where I was living in a self-sustaining community in the mountains in Colorado, and we had a very large greenhouse there. Dragging the hose around to water plants was a real pain, and that stuck in the back of my mind even after I left the place. It would have been much easier to integrate watering into the frame at construction time than doing that hose dance every day.
This guy has a lot of cool projects, and he's one of my influences toward seeing what else this pipe can do.
This is a vine trellis made using bent PVC Pipe.
This misting tunnel was at the World Maker Faire in NYC this September. It is based on a design for a greenhouse that has watering integrated into the frame. We used a tool called a PVC Bendit to make the bends.
