Cost-effective Oxygen Concentrators

[@sitarammeduri8664]

Nice Work. Please provide more information on assembly and zeolite filters. I had a basic idea regarding the process. I'm from India wanted to work on this such that It will help the needy people.

[@juliacodell2726]

What are your sources of the lithium zeolites? I am trying to make my own from regular x13 molecular sieve material modified by soaking in one molar lithium chloride monohydrate. Have you done any work on this? Do you have a web site with more information? Thanks. Richard

[@soportecursos4883]

Nice work. Could I have more information about your project?

[@aswingsharif6729]

This is confusing short video. Everyone knew that LiX sieve for trapping oxygen, is expensive. And then it si mentioned ETH zurich is doing research and conclude that 3 of 18650 batteries form laptop can produce lithium ..for what?? To create LiX? With no further information, seems that ETH zurich would like to copyrighted their discovery and finally consumer will still need to purchase expensive LiX. Please CMIIW.

Hi, do you have a price figure for the BOM?

[@serhioromano]

Please help me. How you call those white containers (sieve beds). I want to purchase like those but I cannot find them.

[@ВалентинКАРАПЕТРОВ-ш5ф]

Hello, Where do you buy white plastic zeolite tubes?

[@nanoindus]

hi, very nicely done. can you share timing diagram for operation of valves? It is slightly confusing. do you have links to more detals.

[@chaudharyavdesh]

Could you please share more information and the design with us. We want to produce some for India to solve their pandemic crisis right now. It is really urgent. We are based in Germany and have some engineers onboard who are working with Hydrogen and CO2 production but we lack someone with Oxygen concentration. I will really appreciate your answer as soon as possible. Thank you in advance

[@salmahayath349]

Did u get any reply? I m from Bangalore, Dr siddiqa, how precious it would be if this technique can be used to prepare cost effective concentrator, our govt is a big failure, we need to come up for our people

[@maxmustermann5353]

Dann schreiben sie doch direkt an die ETH Zürich, wenn noch Fragen offen sind.

[@lizgliz4826]

Dear ETH I am one of the specialist doctors in Australia of Indian origin. I am trying to help sort the oxygen crisis in India as philantropic activity. Could you please help us to see how we can scale this in India?

[@aswinradhakrishnan1547]

To scale this in india you need a zeolite which is very expensive and takes a lot of time all other materials are easy to find

Thankyou sir how much it cost sir.

[@167mm167]

where is the cost-effective prototype??

[@Mickeycuatropatas]

Will this work with bentonite/montmorillonite (cat litter)? If so, this could be built faster and cheaper than LiX Zeolite.

[@grumpystiltskin]

I think bentonite captures CO2 not Nitrogen which you need for a O2 concentrator, which is really a Nitrogen subtractor.

hello my friend we need to BOLIVIA , please send me more information, wich system do you use? PSA-?

[@microtrigger]

What is your site with additional materials?

[@cozierindia]

Hello - Nice video. We need to more information on assembly and zeolites. I'm from India wanted to help the less privileged ones who are far from hospitals and cannot afford concentrates at the same time.

Good day! Please tell me what in this assembly acts as a compressor and what are its parameters?

I dont mean to be so off topic but does anyone know a tool to get back into an Instagram account..? I was dumb lost the account password. I would appreciate any help you can give me

@Jesse Jude thanks for your reply. I found the site through google and Im in the hacking process atm. Seems to take quite some time so I will reply here later with my results.

you look like Oxikit is it? sketchy information with missing detail. or is it oxygenerator..What are you up to sharing this introduction to no content? questions questions here but no replies!
