"Suncor's success can be measured by stock prices that have increased an incredible 400% in the past five years..."

While Suncor's process may or may not be economically feasible without government subsidies, it is absolutely silly to measure their technical success by their stock price!
Just plain silliness!

Actually, Suncor's stocked dropped $10/share a few weeks ago.
