How my rebreather helps the enviorment!

jiseson · 20th November 2007, 23:07

Since i have gotten my rebreather , I no longer need to get that SUV to schlep the 3 sets of doubles and stages to the boat. My rebreather and couple 80's happily fit in my yellow WRX that many laugh about. So i can continue to speed along-getting to the boat nice and early, geting decent gas mileage. I am just like Al Gore- except he has a G IV!

Hey, don't forget all that C02 being scrubbed out and not dumped into the atmosphere thus slowing Global Warming..... And all the energy saved that comes from filling Rebreather tanks vs those big honkin OC tanks! OMG, we are sooooo Green!!!!

yes shinning examples for others. btw got the tanks. tks!

Unfortunately divers love to talk about their O2ptima's... so I'm thinking the 'hot air' generation makes the sum about 'neutral'.

Kidding aside, I've heard people fuss about the cartridge as not being environmentally friendly because it contains plastic (about as much plastic as a couple of the water bottles the person is holding while they are fussing about the cartridge). It's a worthwhile point to consider that any rebreather is almost certainly more environmentally friendly than open circuit.

Hmmm... let's see 100 hours X 60 minutes X 0.85 lpm that equals 5100 liters of CO2 per year I'm not 'dumping' into our atmosphere by living here... quick, does someone more environmentally literate than I, know the formula for converting that to pounds of carbon?

Also, as long as I'm underwater I don't think I'm farting... so can I get credit for the reduced methane emissons too?

Just forget about it. Scrubbing media for rebreathers isn't made from thin air.
In a very simplified way raw material similar to used sorb is heated to _release_ CO2, hydrated, some base is usually added, formulated into the apropriate shape. And voila you have some sorb.

The CO2 you scrubb out when using them is less than the CO2 released when manufacturing the sorb... Besides the CO2 you exhale is similar to the "green" CO2 emissions from "bio-eco-whatever-fuels" and not considered the "same" as CO2 from fossile fuels

But to answer your question. 24 liters of an ideal gas makes 1 mol. The molecular weight of CO2 is ~ 44 g/mol.

So 24 l of CO2 is about 44g. Makes about 1.83 g per litre.

u r forgetting about how much less compressors must run to fill Rebreather tanks vs OC, in addition to the hundreds of lbs of less weight that cars will carry ! as i said earlier u don't need a big GMC dual axle truck to schlep a rig around either. U do have a bunch more hot air put out by CC divers knocking every other rig that they don'tuse! lol

Nope I don't forget it. My comments on the CO2 scrubbing simply have absolutely nothing to do with that part.

Sorry Richie,

The scrubber material has had the CO2 in it driven off when it was calcined or activated. It does capture your CO2 when you breath so there is a zero sum game.

But you are right about the tank filling and think about all the additional huffing and puffing carrying those big suckers around.

Tom who rarely huffs and puffs any more.

Containing plastic is less of an environmental issue than what happens to that plastic once the product is used. Water bottles are readily recyclable at a low energy cost. The cartridge substrate - not so much...
