An RC…Person?!

Now this is just plain Buck Effing Wild.

You put a contraption on your head and suddenly your whole body essentially becomes radio controlled. I'll quote the article at length, but you really should read the original.

I wonder if they could fit one of these things around, oh, I don't know...say... a vagina?

A special headset was placed on my cranium by my hosts during a recent demonstration at an NTT research center. It sent a very low voltage electric current from the back of my ears through my head _ either from left to right or right to left, depending on which way the joystick on a remote-control was moved.

I found the experience unnerving and exhausting: I sought to step straight ahead but kept careening from side to side. Those alternating currents literally threw me off.

The technology is called galvanic vestibular stimulation _ essentially, electricity messes with the delicate nerves inside the ear that help maintain balance.

I felt a mysterious, irresistible urge to start walking to the right whenever the researcher turned the switch to the right. I was convinced _ mistakenly _ that this was the only way to maintain my balance.

The phenomenon is painless but dramatic. Your feet start to move before you know it. I could even remote-control myself by taking the switch into my own hands.

There's no proven-beyond-a-doubt explanation yet as to why people start veering when electricity hits their ear. But NTT researchers say they were able to make a person walk along a route in the shape of a giant pretzel using this technique.

It's a mesmerizing sensation similar to being drunk or melting into sleep under the influence of anesthesia. But it's more definitive, as though an invisible hand were reaching inside your brain.

F1's New Centreline Downwash Generating (CDG) Wing

So some designs are out for F1’s new Centreline Downwash Generating (CDG) Wing ...



All told, they’re wicked. What do they do, you ask? Here’s an explanation from the FIA:

The two-part wing, a result of aero research done by the sport's governing body in conjunction with technical partner AMD, is designed to promote overtaking by lessening airflow disruption immediately behind the car. Following cars would be able to get much closer before losing front downforce, hence making passing easier. The FIA hopes to introduce the wing in either 2007 or 2008, in conjunction with a return to wider, slick tyres.

More info here and here.



The whole thing is to lessen the cars’ aero traction and get more mechanical traction (i.e. tires/tyres, suspension, etc.). The pic below shows the difference in turbulence coming off the car. The top is with the current wing, and the bottom is with the CDG....Tuff...
