I tend to think that extracting oxygen from water should be a catalytic process, not a mechanical one. And who the hell is going to trust their life to a battery cell when they need to decompress or die?

I still think it could be good to carry just enough air or "mix" for the decompression and rely upon this for a long, comfortable dive.

I guess it could be a great little device to add on to those submarines that require the rider to bring their own SCUBA.

I just like the idea of a small tank and mini reg so I can body surf and swim under any size wave without being worried about holding my breath past 30 seconds during strenuous exertion.]]>Feb 17th 2006 5:35PMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/Mar 19th 2006 5:35PMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/Nov 12th 2007 11:02PMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/Jan 31st 2006 5:14PMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/
I also doubt that a swimmer could power a manual generator fast enough to generate oxygen as fast as he breathes it.

However, it's a very cool breakthrough anyway. I think it will find its way into the equipment of technical divers, who can use it to top off their tanks. Of course, the gas we breathe isn't mostly nitrogen anyway, so you'd need a way to scrub the CO2 out, in order to put the water-extracted O2 in and recycle the rest of the gas. This will take time... but it's great to see development finally happening. I've been waiting for this for decades!]]>Jan 31st 2006 5:49PMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/Jan 31st 2006 5:52PMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/Jan 31st 2006 5:54PMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/Jan 31st 2006 5:59PMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/Jan 31st 2006 6:31PMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/Jan 31st 2006 7:06PMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/Jan 31st 2006 8:43PMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/Jan 31st 2006 10:08PMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.isracast.com/tech_news/310505_tech.htm

We are working on a follow up that will reveal the latest work of Mr. Bodner this summer.]]>Feb 1st 2006 2:53AMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.isracast.com/tech_news/310505_tech.htm]]>Feb 1st 2006 2:55AMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/The short answer was it's BS, you would do better trying to sew gills to your skin :).]]>Feb 1st 2006 3:10AMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/Feb 1st 2006 9:53AMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.divester.com/2005/06/07/more-on-bodners-tankless-scuba-system/) and named it as one of our Top 10 Waterproof Tech Items of 2005 (http://www.divester.com/2005/08/05/top-10-waterproof-tech-items/).

Generally, the biggest concern is that the unit is battery operated, and battery-technology hasn't caught up with Bodner's imagination. In other words, the battery Bodner proposes to use drains after an hour. Who cares how much oxygen you can squeeze out of the ocean, because after an hour you STILL have to surface to change batteries.

In the meantime, this application is better suited to underwater habitats, and it will be tested for the first time, under "real conditions" this August, in Lloyd Gibson's BioSUB project (http://www.divester.com/2006/01/23/lloyd-godson-and-the-biosub/).]]>Feb 1st 2006 10:01AMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/Feb 1st 2006 1:20PMhttp://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/http://www.engadget.com/2006/01/31/artificial-gills-extract-oxygen-from-water/Feb 2nd 2006 1:34AM
