@Leonie Falk I’m not clear if this is what you’re looking for, but … during Covid, there was obviously a lot of need for oxygen solutions, and one result of this is a lot of great work, mostly open-source in optimal design of oxygen concentrators.
At least one group in the U. of Cambridge set up with the view to optimising the supply and distribution of oxygen concentrators in developing countries, mainly in Africa. I was involved only at the start of the project, so I don’t have the latest status. Part of the team was located in Kenya (?). The vision was to mass-produce these in Kenya. There are regions there with very suitable zeolite rocks, which (in an oxygen concentrator) are used to adsorb Nitrogen from a stream of air, so that the stream coming out is very rich in Oxygen, up to 95% or in some cases even 99%.
The reason this is interesting is that oxygen concentrators are relatively low-tech, and while they need electricity, they do not need to be refilled with oxygen. They also avoid many of the safety issues related to handling oxygen containers, which work great in London hospitals but maybe not in small, rural clinics with no experts present.
You probably know all this, but if not, definitely feel free to ask me more about the technology of oxygen concentrators. The point you might not know is about the project run with Cambridge, which is just a 40-minute train journey from London. I’d be happy to introduce you to Professor David Fairen-Jimenez, who is a global expert on adsorption technologies and was a colleague of mine for several years.
Congratulations on founding this amazing charity! When we worked on this, one thing I recall was all the people saying “Even without Covid, there is a massive need for oxygen!” It’s brilliant that you’re helping to address that!
