Inquiry (采购产品): Hydro-Electric Prototype I'm developing a new hydro-electric generator and I'm in need of some magnets and coils. The enclosed and pressurized space for the prototype is in a 6.875 inch long tube with an outer diameter of 31.5 inches with and inner diameter of 25 inches. If you have anything that fits that description, or are able to produce something that will, let me know.
