Tesla posted a video to its YouTube channel that shows Tesla engineers working on designing ventilators out of mainly Tesla Model 3 parts. It's pretty amazing to see how many existing Tesla parts can be repurposed into assembling a ventilator.
It wasn't too long ago when Elon Musk was skeptical about whether there was even going to be a need for more ventilators. However, that's changed, and Musk evidently realizes the medical community wasn't overreacting in February when they were warning us that this was going to get very bad.

Tesla now has a team of engineers working on designing respirators out of mostly existing Tesla parts. In doing so, they aren't taking the scarce parts needed to assemble respirators from the other companies that are trying to build as many as possible, and as quickly as possible. It's a brilliant plan, but only if it works.
