Engineers, electricians, physicists.... Tell me what's wrong with this picture.

Keep in mind that this is an all electric car and does not have an auxiliary gas engine.

I assume the writer is claiming that the car is using the spinning hub and belt to drive a generator to recharge the batteries. That would not work, because perpetual motion machines don't work. Running the generator would put resistance on the wheel. Overcoming that resistance would require drawing more power from the battery, so it would be self-defeating.

However, from the picture, it's not clear exactly what that gizmo is for.

Precisely... Now if it had a small gas engine it would be different but then most hybrids and electric cars already have regenerative braking.

Perpetual energy!

Perpetual energy!1

Yep

did it cross your mind that it would take more power that would run the battery down to run that alternator??

they do of course have regen braking that does charge the battery when braking,,

Now if that was on a gas vehicle, it would block the tailpipe where toxic fumes exit. Also you would die from carbon monoxide poisoning. Also to tear down the wall about infinite energy by that useless accessory. Let's say you have a battery at 50%, in order for that accessory to work, you would would need to be going at hypersonic speed at mach 6 or 4567 mph. And that is faster than the fastest car the ThrustSCC which which had a speed of 763 mph. Not to mention that the heat would exceed the batteries capacity, causing the batteries to explode. Also if a EV went that fast, the metalwork on the car would disintegrate and your chair would be flung even faster and upon impact, you would instantly die if the G force didn't kill you.

That powers the flashing light on the hood.

Yet it should be illegal. I mean what if a tire with that smashed into a car? It would easily break a windshield and that thing alone could cut an artery in your throat, bleeding out within minutes.
