Who were you quoting on the Trump comment.Whatever dude. No matter how sophisticated the electronics, the way it goes from applying power to regenerative braking is by SIMPLY CHANGING THE FLOW CURRENT THROUGH THE MOTOR.
And Musk isn't a mad genius. He is intelligent with a massively over inflated ego. And no, he isn't saving the world. Electric cars will not save us. This is why having a high IQ doesn't mean someone is smart. A smart person would actually be able to see all available evidence and recognize that emissions are a small part of our problem and that destroying are carbon sinks are the biggest part of our problem. We have destroyed nearly 1/3 of the worlds forests for crop production and grazing land for people to eat meat. If all the forests that we have destroyed still existed, it would be absorbing near 100% of our global CO2 emissions. So, in terms of people who are smart and recognize the real problem we face, then the people behind companies like Beyond Meat and Impossible Foods are far smarter than Elon Musk.
And again, making money in capitalism is more about one's willingness to exploit the unethical system in which we live, and not about overall intelligence. If you think it has anything to do with intelligence, then explain Donald Trump. Luckiest idiot alive.
