The absurdity of Donald Trump

[Happy Monkey]

I can't speak at all to how well they implemented it, but the idea itself makes sense. If you don't run out of battery, the gas motor never turns on, and it is an electric car. For regular use, you never use gas.

If you do run out of battery, you can do two things - run the motor to generate power, use the power to charge the battery, and then run off of the battery, or run the motor to generate electric power and run the motor with that power, leaving the battery drained until you can plug it in. The latter seems more efficient.

BTW, gasoline uses less energy than recharging from fossil fuels burned in some distant generation station.

I doubt that, or it would be more efficient to run your house off of a generator than the grid.
