What I've seen work, especially for the new technologies, is that—and it's largely been provincial governments that I've seen do the work, one good example of which is the MaRS facility in Toronto. MaRS is an institute funded by the Ontario government that takes new medical technologies, clean technologies, and other sciences, when it's really just a mentor and his idea, and they professionalize him. They give him lawyers, they give him accountants, they coach him on how to make presentations, and they get him to a stage where the idea is bolstered by all the other support services.
I've seen those models work in Ontario and British Columbia, and my best suggestion would be to try to have more of these institutes across the country.
