He is working on the air flow thing. The newer models have dual fans, one sucks air in while the other blows it out. He's experimenting with new stuff all the time. He has a basic blueprint with options and is in the process of streamlining and improving them and building a website. They are modular and come in pieces which allow you to use just the front, front and sides, or the whole thing i think and can have castors for mobility. Transportation is something he's currently working on. I'll try to keep everyone updated if i can but feel free to email him from his site. He's really cool guy and has been a musician for a long time. He'll have better answers than i do.
