Seriously, what a cool concept!

Paint-on solar technology has been coming for quite some time, but the amount of power these paints could generate has always been very low. Now, by combining cutting-edge thin-film solar technology with wind power, Mercedes can bypass direct battery charging and create hydrogen fuel to assist that battery. But wind power has traditionally been all about blocking the wind and generating power with out of the pressure this creates, but we obviously don’t want our modern, streamlined supercar to be covered with wind vanes that reduce mileage — how does this work?

Mercedes-Benz’s multi-voltaic silver paint manages to incorporate electrostatic wind generation into the paint-on solar cell. This means that just the movement of wind over the car’s body (only when stationary) will create a charge the car can use for hydrogen production. This means that as you roll up to a red light your brakes and front shock absorbers are helping to charge your rear-wheel batteries, and once you stop the wind is helping to create hydrogen to assist them — and more fuel is coming from solar energy during the whole process.

My Volvo XC90 a long time ago had a ground level ozone "smog eater".   It basically used the force of the wind to separate the carbon from the oxygen.  This is the first I've heard of using that force to try to capture electrical current by taking advantage of the wind resistance and the electricity resulting in splitting ionic charges. 

Standard fuel cells are just one metal on one side and another metal on another side having forced air or gas flow over it.  The one side captures the negative ions, the other the positive.  If you are lucky, as the ions split off, you get oxygen, or h2O or other clean side effects. Having an hydrogen side effect is interesting--if you can recapture it.

That's fascinating.

Finally these cars feel like they're benefiting from all the science we know!

Now, why can't real cars have these features?
