Apparently Best?

Peer Review by Joshua Pearce

What we are actually producing locally is much more modest - https://www.appropedia.org/MTU_3-D_printing_PPE a few hundred face sheilds, dozens of masks and a handful of the tools to speed up cloth mask making and vent splitters. You can see what we are doing for masks - if you click on the filter link https://www.appropedia.org/Face_mask_reviews#Filter_materials it covers the materials...

We are working desperately to get a real open source ventilator going -- for a summary of the literature see https://f1000research.com/articles/9-218/v1 Short answer is no one has actually done it yet: MIT, Rice, Ireland and OxyGEN and a few others are really close - but delayed only partially released their code - the software to do the pressures correctly is the really hard part - we are working on it too -- I expect within the next few weeks one of us will get it. I have two artificial lungs - the fancy $10k kind on loan so I can test anyone's system....hopefully soon we will have something.
