Here's an open quesiton. What are your favorite plays other than Niogold? Commodities other than Gold?

I've been wading back into uranium with CCO and PDO. Now looking for a junior. Considered CXX and STM.

I've also been playing some 'green' plays to some success. VRB is a battery technology company that's doing fairly well since I got in and seems poised to run higher.

Another play I like mostly because of the actual product is ZEN or Zenn Cars.. this is a Canadian electric car manufacturer. My plan for Zenn was to buy a couple thousand shares and if they ever go up to the price of the car, I'd buy the car. However, the car isn't allowed on Canadian roads yet so I have some time. It would seem there's mounting pressure to allow such a Canadian success story's cars on Canadian roads and I think that will happen soon. They're coming out with a couple of models that will have a faster top speed, which should go a ways in making regulators less apprehensive. Canadian approval would boost the stock's price substantially. Today they're up 16% on speculation. I need the stock to go another 80% or so to get my car :)

Anyways, love to hear other's comments on what they like or considering.
