> Lamborghini also intends to make the supercapacitors out of carbon fiber panels that can be used to form the body of the car—so the Terzo Millennio draws energy from its own body. In other words: the car itself is the battery.

So does that mean that if you happen to have an accident, there is a chance that a good chunk of your battery gets short circuited? That sounds somewhat dangerous...

> the company will develop in-wheel electric motors, which would eliminate the need for a single large engine. A 'single large engine' is only needed in ICE cars, electric vehicles have a 'small' motor, and can easily have multiple motors. It's already being done by Tesla and Rimac. To my knowledge, an 'in wheel' motor would not be desirable due to unsprung mass, so a motor on the chassis connected to the wheel with…

Looking at those wheels, and all the fancy material science speculation, they probably expect to use the wheel structure as the motor. If the wheels themselves are acting as coils, then there isn't as much extra unsprung mass.

That design doesn't look like it has any springs anyway, so the whole thing is a giant unsprung mass, :p

Every time the idea comes up, "unsprung mass" is thrown like a pavlovian reflex. I'm curious about what they have in mind for solving the constraints. They aren't the less experienced people around.

Large outrunner motors like Emrax aren't much heavier than typical cast alloy wheels. Assuming wheel-motor eliminates disc brake components (sounds scary, right?) assembly will probably be even lighter.

Just FYI for Mac users, latest Safari has this feature built-in.

The way apple has stood up for consumers through built-in Safari features is straight up inspiring, with autoplay disabling and tracking disabling.

Considering they lag horrendously in pretty much everything else, it's a bit of a desperate ploy for attention...

> Supercapacitors store energy physically and don’t generate the heat of lithium-ions, but as of yet they don’t offer as much power. This probably should read "don't offer as much energy". Almost every mainstream media article about electric cars mixes up these two concepts, sigh.

They don't store energy physically. They trap electrons. They hold a static but still electrical energy differential. "Physically" sounds like they store mechanical energy. Either way, I'd hate to get into an accident in a car with capacitors build into its structure. Smash into a wall and there would be a bit of a lighting storm. Current carbon fiber cars burn like torches. With electrical energy stored in amongst that carbon, this car might go off like a bomb.

The wheels themselves can not act as coils because of eddy currents.

Yeah, and I bet that carbon fiber burns real nice.
