Tesla Ventilator
Yes, this is an impressive amount of work done in a few weeks by a small team at Tesla.  However, medical devices, especially for <i>life support</i> systems, are not a Hackathon project.<p>These devices breathe air into patients lungs.  They need to be manufactured in clean room conditions, with medical grade parts, not plumbing parts from a big box store.  They must be designed and tested to ISO specifications.  If this fails, the patient can die.<p>I can't imagine any hospital or doctor careless enough to connect one of these to a patient, even in this current emergency.<p>The smarter idea is to ramp up existing proven designs, not reinvent the wheel and basically do a publicity stunt about your engineering talent.
