Ventilator made from car parts
Kleinstein:
Compared to some of the crude air pumps with a fixed rate / volume the Tesla part may actually work. At least it looks like the got the basics right.
They don't show the details on how the control is handled. Chances are there is still some of the software missing, but as far as I can tell the HW side may actually work and have the capability. With the valves there may be the problem, that the same or similar parts may be used in the regular designs too - so they may even compete for the same parts.
Overall the design does not look that much different from the proper medical ones in use. The difference and higher price comes from certification, high reliability / testing, insurance and in normal times relatively low volumes. Normally there is quite a bit of extra paperwork going with such a critical medical device. It starts with the disclaimers in essentially all normal electronics part that do no allow the use in life support devices.

Unfortunately all those quickly hacked together ventilators will become e-junk after we'll have survived the corona virus, because none of them will get a standard approval. All they get is a temporary emergency permission.

Oh, funny how that was not put in the news. His name was all over the news and by the sounds of it fake news at that as he was not going to do anything until he passed the criteria but they talked as though it was a done deal. Then a fuss was made about Gtech and Dysons name was never mentioned again so mainstream joe public probably still think Dyson us making ventilators.
trophosphere:
I don't know if it's still true but didn't repair shops have problems sourcing spare/replacement parts for Tesla cars? I had a friend that bought a Tesla but he got into an accident and couldn't have his Tesla repaired for a couple months due to lack of availability for a couple of parts. If that is still the case then using their designed ventilator will likely still not address the supply problem.

Here's a reference to G-tech: https://www.malverngazette.co.uk/news/18345951.worcester-firm-gtech-coronavirus-ventilator-not-used-not-meet-government-standards-city-mp-robin-walker-says/
I can't find the reference to Dyson. Existing designs are preferred here for obvious reasons: https://www.theguardian.com/business/2020/mar/23/carmakers-make-nhs-ventilators-coronavirus-uk-government-nissan-rolls-royce
AFAIK they said they were going to order stuff from Dyson but it went quiet suddenly and then "existing designs" started appearing suggesting that the existing manufacturers creating something from scratch was more of a risk than a benefit (I agree with this). To note the original Dyson proposal came from their own press releases rather than the government.
Tesla's design is based on an existing design repurposed with off the shelf parts that can be mass produced already so that's sort of in the middle.
Edit: I understand the Smiths paraPac is what they used to stuff in ambulances. Not sure what's in there now. That's probably got the most amount of users out there who know how to fix it and work with it and can pass knowledge on.
