Elon Musk offered to help make medical supplies for US hospitals (like ventilators, masks, etc) and Mayor de Blasio is taking him up on the offer. After a long twitter exchange (prompted by Nate Silver), it appears as if Tesla/SpaceX are reaching out to the New York City government and may supply them with direly needed medical equipment. I think this is an awesome initiative by Elon, and could be a win/win. NYC gets help, and Tesla's factory employees have something to do.
