This isn’t some theoretical thing I’m making up. It’s really basic math and physics you should have learned in high school. To do a trip of a few miles you would have to charge for a week. Here is a good explainer with demonstration cars that have been physically built, maybe that will help drive the point home.
I have used the most expensive microwaves money can buy from Kenmore and GE and honestly the sensor reheat is just always complete shit. Way over or underdone every time. Soup/beverages are the only thing it’s good for. And the popcorn is also perfect every time.
