Great idea. Simultaneous to these types of home-brew projects...we also need someone (President? eCelebs? etc) to promote and organize fund raising efforts to simply buy and distribute cheap but effective ventilators.

Imagine a WWII style "war bonds" effort, but instead to build and distribute say 5M ventilators over the next 6 weeks.

In addition to this, we must re-purpose closed schools (gyms, cafeterias, etc) into make-shift CoVid19 triage centers where affected patients can be put on cots with saline drip, drugs, and ventilation. This is doable, but we need to do it.
