Then they released a home battery with a sub 10 ms ATS which is necessary for seamless in-house grid/off grid transition. Finally the push for a reusable rocket booster was entirely a management decision on his part. If the next words out of your mouth are "he didn't do that, his engineers did" please come up with something more original. This isn't reddit.
