Ah. Another day brings another very interesting bit of information about a user that I follow. :c)
For a long time I have heard of the benefits of silver (generically).
I have a question.
Have you considered expanding the product range to include the produce of the actual machine?
Why?
Some potential users might be inclined to try out the results before getting the machine that makes it.
Some potential users might be more inclined to buy the product if theyhave a side-by-side comparison of product and machine.
Some potential users might actually have less interest in making their own because of a variety of reasons - and would prefer to buy the silver itself.
It would produce a new revenue stream - I'd suspect.
Another possibility is to look into a lateral expansion of the product line. Perhaps the same tech used in this product - or the bi-product - can be used to produce other products that might not have occured to you (and may not even be health-related).
In terms of SOE - I trust that you've covered Youtube, Twitter & Facebook.
Perhaps a business-to-business approach? MRSA is a resistant scourge - so perhaps approach individuals in the medical profession to see if they might be interested in producing such for their patients at their office (profit motive).
These are excellent suggestions, @pathforger. Some things to think about, @creatr.
