How do I invest in nuclear energy?

-- Steve from Wyoming

James J. Cramer: It's hard to invest directly in the nuclear industry, but I think you can own Cameco(CCJ Quote), which sells uranium to the nuclear industry, if you want exposure. There are some other players, like USEC(USU Quote), but I view Cameco as the "best of breed" in this space.

What is your take on Jones Soda(JSDA Quote)?

-- Jay from Tulsa, Okla.

James J. Cramer: Jones Soda has a deal with Starbucks and Target, but its high cost of growth is taking a toll on the bottom line. I like the long-term trends, but until I see this beverage play improve its operating execution, I would rather own Pepsi(PEP Quote).
