Zombie Traps

Movies always depict groups of humans manually sweeping areas for zombies, but devices specifically designed for the task would be much more effective and far safer. To catch them alive for experimentation, the simplest would probably be a shipping container with a one way security turnstile welded into one end and a noise maker for a lure. Airlift it in, and then once full, pick it back up again. Destroying the zombies is more difficult, and depends on exactly what type is being encountered. Those that are simply infected but mortal offer many simple solutions, such as exposure to radiation or other toxins, but I will focus on the much more problematic undead variety. The need to significantly damage the brain and the fact that they could be crawling or of widely varying sizes complicates things considerably, so a crusher would probably be the most effective. Similar to some compacting trash containers, solar panels (mounted on an appropriately tall mast) would allow for extended operation without fuel and likely be the most practical option, although there are, of course, also highly impractical ones. Again, a noise maker would draw zombies inside, through a one way gate and then once filled to capacity they would be crushed by a motor highly geared down to be very slow but powerful. The wall opposite the crushing panel should be releasable, sliding sideways via another powerful, slow motor and built heavily enough to oppose the compacting force, so that the remains could be scraped out and pushed aside to create more room for prey. While simpler, forcing the zombies through a grate would be susceptible to jamming were a foreign object to somehow make its way into the trap. Obviously, a fairly open site would need to be chosen for the growing pile of gore, although decay should limit its maximum size and allow the powerful actuators to continue to deal with it. A parking lot, lawn, or even a street intersection would probably be adequate.
