Producing silicon for batteries may be a great market, but I had invested in HPQ for the prospect of using the powders to create hydrogen.

I still don't understand the sizes and why, and what applications use the different sizes. If they are using a grinding process I would presume that there will be waste that isn't acceptable to the industry the grinding is producing. So would these filings and powders produced in the grinding process be able to be used in the production of hydrogen? Or can these filings, the byproduct from grinding need to be further ground into powder be able to be used in the production of hydrogen.

It's one thing to produce a product for an industry, but then to be able to have the byproduct as a valued commodity I would say the sky is the limit.
