Background: When one uses a snorkel and a goggles what one really needs is a valve that fits over the nostrils and is held in place with a strap much like inexpensive swim goggles are.
The valve would allow one to exhale oxygen depleted air through the nose while at the same time breathing in fresh air through the snorkel. This would prevent oxygen deprivation from spent air expelled in the snorkel being breathed back in.
As always I would patent this myself if the Demonic race was not magnetically pulsing me with a synapse attenuated frequency while I try and concentrate and learn.
