  • I often hear people saying “But where does the electricity for the EV come from? Driving an EV is not better than driving a diesel.”

    They have to realize that the thiny ICE in your car is optimised for weight, and has an efficiency of 30-35%. So about ⅔ of the fossil fuel is turned into heat and blown out of the exhaust. Compare that to the turbine in a coal or gas plant, which can archive up to 90% efficiency.

    And don’t forget that an EV is an investment, which will likely still be on the road in 20 years time. The electricity mix at the moment is still rather fossil fuel heavy, but this will change completely within the next 10 years.

    Edit: not 90% but 40% efficiency. See comments below

    That’s not really true. Pressure doesn’t really make a difference if there’s no pressure-difference. The controller body is filled with water and is pushing back. The pressure alone wouldn’t harm the controller.

    I do agree with you that the controller would be mulch though. It was in a pressure vessel that imploded at 3800m depth, so everything inside the pressure vessel would be crushed as well.
