Hey ya'll! I've come to the Physics Forum when I needed help with homework, but only to observe. This is my first time posting, and I'm glad to be here! I've got a question about, electrohydrodynamics. Recently, Elon Musk put forth his idea for the Hyperloop. For those who don't know, Hyperloop is like a pneumatic tube transport system for people, vehicles, and cargo: http://www.teslamotors.com/sites/default/files/blog_images/hyperloop-alpha.pdf Elon said he doesn't want to start work on it now with SpaceX and Tesla to worry about, but that he would be interested in anyone's opinions or suggestions on how to improve it. An 'open source' project for the internet. I got an idea while reading an article about lifters, maybe it would be possible to keep air flowing around an object if you cover it in these EH panels, that alternate like the legs of a millipede, rapidly, to match the wind speed? Here's a diagram of what I mean: I was wondering, can lifters arrayed in this fashion and still work? I'm not saying it needs to be powerful enough to shoot the capsule down the tube at record speeds, but enough so that air may flow around the capsule, mitigating drag. I guess this would apply to rockets, boats, cars, propellers, anything really.
