Q: do you have any helium related stocks that could be worth watching?

Q: If one believes that the move to a hydrogen economy is inevitable where should they be investing? My sense is that Shell is one of the better plays from a supplier perspective (c/w 5% dividend on the ADR) and maybe Toyota from a transportation perspective. However, neither offers a particularly inspiring 5 year chart. Do you have any better suggestions (possibly Canadian, though I am looking for a relatively secure name rather than a small start-up)?

Thanks for all your help; all responses on your site seem to contain something I find useful.
