Answer 2

With a nickname like "Hardware Hobbyist" I spend time in hardware stores where a good selection of many kinds of plastic pipe can be found, mostly all PVC - someone correct me. It has a great use in making small rotators that spin in the wind by fitting the pipe with bearings and drilling holes in it for rods that hold the blades. On one of them I wrapped a few layers of black tape over the surface that drove by friction the contact wheel of a small bicycle generator. It lit some lights and what all from just this bit of wind energy at a few miles per hour. HDPE pipe doesn't seem to be as readily available although it may be cheaper, as a product without chloride.
