Very quickly, first of all, obviously our first problem is transportation of the ore to somewhere where we can actually do a lot of refining. Then there's the energy. Clearly, we have to concentrate the elements of interest at site. We have to do as much as we can to reduce the mass of material that is shipped out. So those are the two initial problems: energy and transportation.
The next problem, then, is how to go about reducing the amount of material we need to ship out. I pointed to the metallurgical side. Part of that metallurgical work has to be done on site. We have to reduce that material. We have to really invest in research to develop the methods to extract successfully. The problem with these critical metals we're talking about is that we don't have the years of experience we've had with the base metals and precious metals and so on. We're in new territory. We do need to invest in this research.
I'm going to change the subject slightly. I really think the federal government has a huge responsibility to educate the populace on critical metals. The reason I say this is that it impacts immediately on investment. If the population doesn't know why we're hunting niobium, or why we're looking for rare earths, then why should they actually invest?
I'll give you a really good example. How many people know that niobium has the highest threshold of superconductivity of any element? Well, you can ask who cares, but the point I'm making is that perhaps we are interested in magnetic levitation trains, and for that you need niobium. How many people know this? Can you imagine a Canada where we have a supertrain that goes from Montreal to Vancouver in eight to 10 hours? This is not pie in the sky. The Chinese already have one operating at over 600 kilometres an hour just outside Shanghai. The Japanese are planning to have a maglev train that runs from Tokyo to Nagoya, a distance of 300 kilometres, in about 40 minutes. This is something that we could educate the populace about. That would drive investment in the critical metals area. I've given you one example, but there are many examples like that.
I know I changed the subject, but I really wanted to hammer this point through.
