Commercial vanadium metal, of about 95% purity, costs about $20/lb. This is a tiny layer, so even at the 99.9% purity level cost of $100/oz, materials cost is not likely be a critical factor. The main constraint is that it's not making much power -- at this level it's really for very low power applications, especially things like sensors and comms. |
