[QUOTE="John Roberts, post: 48497, member: 126"] Re: Crazy idea for a powered sub Already done, AFAIK Jon Risch (at Peavey) got a patent for that years ago... You need to give two ports slightly asymmetrical resistance to airflow in opposite directions, so the natural AC air movement in the ports gets rectified (so to speak) and turns into DC overall flow in one and out the other. You can do this a little more simply by mounting one port low and the other high to take advantage of natural convection. FWIW lots of smart folks have been thinking about such things for a while now, but keep thinking, it's good exercise for the gray muscle, and surely there are more ideas out there yet to be discovered, and the best ones are painfully simple, after you figure them out.
