I didn't dismiss them. In fact, my industry is advocating them and is doing a lot of work on all of them.
I would point out that the development of rare earth minerals is a very costly experience and requires a great deal of energy input. If the energy input is too expensive, you won't develop those rare earth minerals, and that means you won't ever develop the kinds of electric technologies and other technologies that the member's referring to.
We all want to develop those things. Affordability is fundamental to all of this.
