There are also showers that reclaim shower water while you shower. Most water goes down the drain clean. It’s apparently easy to separate that from water that’s mixed with soap and dirt, and send it back op the shower again. This can dramatically cut back on your water use much more effectively throttling the water flow.

As stupid as this is, I see mostly positive consequences coming from this: either they’ll oppose TSA, or they’ll refuse to fly. Both sound like a win to me.
