Given that we're only at a point where maybe there are 200 tonnes or so, we don't have any commercial scale, by any stretch of the imagination. So given that we're not at a commercial scale but still at demonstration projects, what was your idea? I'd like to get your feel for what you think the transition period is.
Ms. Milewski, you also said “the current” regulatory environment. That suggests there could be a regulatory environment that might be successful. It begs the question then, if you're going to have a transition period, whether you must have some kind of regulatory environment that would have to be in place for the transition. Can you speculate on what that transition period is and what the regulatory environment would be?
