Have governments made orders (legal or purchase) for manufacture of ventilators by large scale companies?
Presumably ventilators are a relatively niche product - what's in them that the World's industrial complexes can't ramp up production of within a couple of weeks?
I imagine it's the pumps that's the limiting factor? Given humanity already has the working tested, established designs.
Can't governments requisition the design, turn the original factories in to test only, or construct and test, centres. Instruct the mega-corps, publicly, which parts they are to make and by when ...
In the West we throw away tens-of-thousands of highly engineered products every day; surely we can step up now?
