Talk:Artificial gills (human)

Different Method
I don't know how relevant this is but, it is possible for the water molecules to be split using electricity and then if the oxygen was separated from the hydrogen large amounts of water wouldn't be needed. However I don't know how much electricity would be needed. But this is much more likely way of breathing underwater then the methods suggested in the article. —Preceding unsigned comment added by 66.71.87.182 (talk) 18:04, 6 February 2011 (UTC)

oxygen toxicicity
Just extracting oxygen out of the water is useless to a scuba diver. 100% oxygen becomes toxic at about 6m. I train my students in about double that. You need a gaseous medium, preferably something like nitrogen. Where do any of these systems aquire that? Or do they work as rebreathers? Either way it should be I the article — Preceding unsigned comment added by 203.91.93.244 (talk) 15:59, 16 January 2014 (UTC)

Amount of oxygen required by a human
The two numbers given on this page, 1 liter / minute and 1 mol / hour, contradict each other: 1 mol is 22.4 liters at STP, so 1 liter / minute is approximately 3 mol / hour. Kerrick Staley (talk) 21:41, 3 March 2015 (UTC)

Triton artificial gills
Though it appears the "Triton artificial gills" aren't really a rebreather as previously claimed, I noticed that someone else tried to add it to this article. I decided to post a copy here in talk in case someone else comes to this article looking for something about it. Also, there's a lot of talk about it on Reddit at: https://www.reddit.com/r/shittykickstarters/search?q=triton&sort=new&restrict_sr=on •  Sbmeirow  •  Talk  • 08:54, 2 April 2016 (UTC)

Triton
Triton, "the world's first artificial gills technology" is a Swedish and Korean organization that claims they have created artificial gills for humans. Released as an Indiegogo project on March 14, 2016, this technology claims to allow divers to spend 45 minutes underwater at depths of less than 15 feet. It claims to use a micro porous hollow fiber to keep water out while permitting oxygen to pass through into an interior space, where it claims it is compressed by a modified dual micro compressor so that it can be used for consumption. As of March 24, 2016, the Indiegogo project had been backed for $637,000 of its original $50,000 goal. Triton claims that it expects to deliver in December 2016, and has several options available, ranging from a single unit to a package of five.

Scrutiny
The Triton breathing device has been debunked by a variety of sources. Triton responded that it cannot release more technical information because it has not yet obtained patents on the tech. However, they responded to Deep Sea News on Facebook and claimed that the article was written when Triton had just started. Promotional videos have also been questioned, because they cut scenes too frequently to guarantee that the divers are actually breathing off the device. Triton evades the common problems with artificial gills by claiming it has invented a new exponentially superior battery, a "low power" micro-compressor, and a micro porous hollow fiber that can exclude water molecules while permitting oxygen to pass through. However, it does not respond to the problems with flow rate, the high metabolism of humans, or other fundamental problems.

Dissolved oxygen density of water and human oxygen requirements are limiting factor
As referenced in the article, the density of dissolved oxygen in water requires a very large volume of water constantly flowing through the gill to meet human oxygen needs. — Preceding unsigned comment added by Klaun (talk • contribs) 19:57, 19 December 2017 (UTC)
