Powered by Sterno made of wood, sounds like a recipe for fire. It took two cans of heat to get it moving the first time but continued to spin almost as fast after removing one can. It serves no purpose yet but tomorow I'm going to add a pot- pouri jar just under the rotor blades to give it
reason for being. I'll call it counter rotating pot-pouri diffuser.
I'm working on downloading a driver for my video cam so you can see it in action.
