Cool Tool: Rebreathers: "Rebreathers are underwater life support systems that permit you to stay longer at deeper depths. It's not hard to make a normal scuba tank last for an hour (or more) very near the surface. At 60 feet, this duration drops to less than half an hour. At a hundred feet, maybe 15-20 minutes. A recreational-grade rebreather, however, will give you several hours at any depth in the 0-100 ft. range. So the deeper you dive, the more advantageous the rebreather becomes. Rebreathers always give you more time, but especially give you more time at greater depths."
We're talking about possible 3 day underwater life support. Freakin' crazy!

Re-breathers give you more air time by scrubbing your breath out through a carbon filter to remove CO2 and letting you recapture O2 that would otherwise be waisted. You are, however, still time constrained by nitrogen absorbsion, so unless your planning on a couple days worth of sitting in a decompression chamber, 3 days underwater is still not practical.
READ THE ARTICLE
"The possibilities for underwater exploration using rebreather technology are amazing. Bill Stone, an engineer who has designed some of the world's most sophisticated closed-circuit rebreathers, famously conducted a 24-hour non-stop dive using one of his early prototype designs. In truth, he used up less than half of the total capacity of the unit, meaning that he could have gone for at *least* another 24 hours, and perhaps as much as an additional 48 hours. Yup, that's 3 days of life support underwater from one self-contained pack."
Shut up bitch. Of course its possible, but not practicle for most divers. Read my comment.
Yeah, that's what that post was all about, practicality. Practicality would be not to go so long under water that you would need a supply of air. Ass.
