So at North Carolina State University, we challenged our students to come up with a simple solution, and this is what they came up with: a simple, modified screw auger that can move the waste up from the pit and into a collecting drum, and now the pit worker doesn't have to go down into the pit.
在北卡罗莱纳州立大学， 我们让学生们想出一个简单的解决方案， 而这就是他们想出来的方案： 一个简单、改良过的麻花钻 可以将这些排泄物 从坑里运上来倒进一个收集桶， 现在这些清理粪坑的工人 不再需要下到坑里面。
