Just a note...Lithium Hydroxide canisters were aboard my submarine in case of emergencies. I would assume that the navy did extensive research and found these to be the best purchase for the limited space available.
My .02 cents

Jon no I did not make the Maine convention. Unless it is a lot more money, I am
really leaning towards the cartridges.
I was looking at there web site and they have a product there called Lithium Hydroxide Cartridge.
I am assuming this is a different product than the Calcium Hydroxide. Do you know anything
about this one.
As far as firing this project up, I am willing to do so. It seems like a worth while project
and I need to get one built.

Dean,
I've been recommending them for quite a while, and the company has been
very good about working with us. They sent a Rep to Maine last year to
talk to us about their products (don't recall if you were in Maine last
year or not) and at one point were willing to make us a dealer. One of
the issues with their product for small subs is that you'll have to
modify an existing rebreather canister. We started working on that some
time ago but it kind of dropped by the wayside. I never officially
published the info, but you can review a prototype modification at
http://www.psubs.org/scrubber/
Micropore has shown an interest in working with us to come up with a
solution for small subs, but we need volunteers to move the project
along. As you stated, the cartridges make life easy both in storage and
reloading during a dive. However, the cartridges are significantly more
expensive then traditional soda lime products. On the plus side, they
are better performers.
I still have a canister that they sent me for prototype work. If you
are truly interested in going this route, I'd be happy to start it up
again and we could even send you the unit for testing in your sub.
