I've been thinking of this for some time...but I'm no expert.  Seems like it could be a solid choice given 1) the non-renewable nature of He, 2) the current use/supply ratio, 3) the ending stocks to be sold off to completion in 2015, and 4) it's need in highly valued industries (medical, national security, industrial fabrications).

See the article I've read recently.

How would one invest in this, assuming supply will crash?  Shares in companies that distribute it/have stocks (eg-AirProducts or Praxair)?  Put up bulk liquid storage tanks in your back yard?

Just some thoughts off the beaten path of usual commodities...

Thanks in advance,
