“We will make ventilators if there is a shortage,” the 48-year-old tech pioneer tweeted late Wednesday.

His ventilator tweet had more than 10,000 likes within hours, and quickly received a rush of excited praise — as well as ridicule for saying the offer would be “if there is a shortage.”

“IF??? Which planet you on, mate???” @TheAiLeen_L asked, while Andrew Wortman said, “There is a shortage RIGHT THE F–K NOW.”

“Start NOW!” Bruce Bluestein urged him. “We have a shortage and health care workers on the front lines are desperate.

“You have a chance to be a hero and save many lives. You have the power, the money and the organization. Go for it!”

Tesla would join a group of motor companies offering their help, with General Motors and Ford both already in talks with White House officials.

The offer comes amid escalating fears that the nation will soon run out of the vital medical equipment — with Gov. Andrew Cuomo telling the “Today” show Thursday that getting ventilators “is going to be key.”

Musk’s offer came just a week after he tweeted that the “coronavirus panic is dumb” — a tweet that was liked 1.7 million times.

While he appeared to be changing his tune, he still insisted Monday that “danger of panic still far exceeds danger of corona.”

“If we over-allocate medical resources to corona, it will come at expense of treating other illnesses,” he claimed.

On Wednesday, Tesla agreed to reduce the number of active workers at its California vehicle factory, a county spokesman said, amid regional lockdowns to rein in the virus. The company employs more than 10,000 workers at its sole U.S. auto factory in Fremont.

It was not immediately clear how the motor companies would manage production with each seeing factories closing because of the escalating pandemic.
