In 2023, the United States imported about 8.51 million barrels per day (b/d) of petroleum from 86 countries. In 2023, the United States exported about 10.15 million b/d of petroleum to 173 countries and 3 U.S. territories.

The resulting total net petroleum imports (imports minus exports) were about -1.64 million b/d, which means that the United States was a net petroleum exporter of 1.64 million b/d in 2023.

Other prosthetic/mechanical changes to hearts don’t do that, so I would guess this one doesn’t either. It would require interfacing with the brain and decoding stimulus, which would be much more complex.

Usually the recipents just keep activity low or pass out when they need the energy/heat dissipation and can’t get it.
