You're absolutely right, Peter.
Google has a great search engine, and I like to keep a Google Advanced Search tab open at all times in my Vista browser. Whatever you have in mind, Google can find many references to it very quickly. I know that you are surely very proficient at using advanced search techniques, Peter, but to Dambit and others who are less experienced with search engines, this should help:
In an advanced search, you can narrow your results so that they are more apt to directly apply to what you have in mind. For example, if you use the exact phrase "Magnesium sheet" along with the word Hydrogen
in the All these words
pane, this will narrow your search to 732 results. If you also add the word supplier
to the All these words
pane, you will narrow your search to 216 results, and you will find a wealth of information about suppliers of magnesium sheet metal made specifically for Hydrogen storage and Hydrogen generation applications.
Incidentally, it is interesting to note that Francisco Pacheco used sea water in his hydrogen generator. Daniel Dingel also used sea water in creating hydrogen. Sea water naturally contains magnesium, and much of the magnesium produced in the U.S. comes from electrolysis of fused magnesium chloride derived from sea water. Perhaps the magnesium in sea water is a boosting factor to hydrogen which allows sea water to burn with a 2,000 degree flame when exposed to John Kanzius's Radio Frequency Generator (see YouTube - John Kanzius - Saltwater Burns
Note that positively charged sodium ions and negatively charged chloride ions are the most abundant ions of sea salt, and are the third and fourth most abundant of the 13 constituents of sea water, directly following hydrogen and oxygen, while magnesium is the fifth. We know that sodium and chloride (from Hydrochloric Acid as a result of volcanic venting to sea water) are both useful in electrolytes. It is a known fact that magnesium will react with diluted acids to liberate hydrogen. Sea water has diluted acids, but overall is slightly more alkaline than human blood on the Ph scale.
Just some tidbits - food for thought and discussion - from an old salt,
