Yes indeed, I answer to "Mad Scientist" for sure... Just don't call me "Late To Dinner." ;)

I will of course attempt to eliminate your confusion... YES! That is exactly the kind of tube you would see coming from an oxygen bottle or concentrator. It's called a "nasal cannula" and you can buy them (pretty cheaply!) on Amazon.

And, YES! I am breathing the Brown's gas via the same kind of hoses you'd see in a hospital.

My intention is to continue this series (as I have time!) and make everything perfectly clear; meanwhile, if you check out George Wiseman's Eagle Research AC-50 page, you may be able to satisfy your curiosity sooner; and of course, as I continue this series, you'll be able to read about all the pieces and parts I've purchased in order to build this beast... :D

I intend to publish a parts list and sources (lots from Amazon, and quite a few from Lowe's).

Thanks for coming by and asking the tough questions! I really appreciate interested readers!

BTW, I need to read more about "Kangen water" but I think the water I bubble the gas through gets to be pretty much like that... ;)
