What Is It?

Well that looks like an aircraft wing. So I am guessing those create vortices in improve wing efficiency? It certainly doesn't look like your original pic at all.

No its the new LynDoorMat Batterie Charger!

Step into your day with a charged up batterie. Just 150 steps from each familiy member per hour and you are up and running at lunch time!

That's why it doesn't look like a wing, it's a truck. G.A.

it's all about flow separation. I need more data on the plasma avenue before I'd accept it as viable. either way it's interesting

Not sure about that, google images didn't help me out with that pic.

Some great sleuthing there, Sir Robin!

Actually, it was happenstance that I knew the answer because a colleague had sent me that link in an email not ten minutes prior to this posting because he found it very interesting as well.

"They are breaking wind. With ions."

Is that what happens when you eat too many statically charged beans?

Good, we have free ions by then.

heres the answer.........it's plasma

The "charge" of the plasma is supposed to 'hold' the airflow against the surface and thus reduce turbulence, so as to increase fuel economy by reducing drag.

if you watched the clip you'd see your premise isn't what they're going for. they're creating wind VS wind to set up a vortex. this creates separation.........reducing drag

https://youtu.be/8zQokKKWBLg

so the plasma creates it's own wind right at critical points in the very front of the truck so the air will separate and not stick so much to the sides of the truck, reducing drag. it's all explained in the clip

If that plasma has a net charge that isn't completely neutralised by contact with the truck, that truck is going to build up a considerable charge over time. How do they plan to neutralise that charge? Drag a chain?

It still looks like a new type of cheese grater to me.

So, I'm to assume that this disrupts or enhances the "boundary layer" layer effect?
