Thanks for sharing that. I use a lot of polyester garments for sports and feel kinda crumby knowing it really hurts the environment. Hopefully these sound wave

Thanks for sharing that. I use a lot of polyester garments for sports and feel kinda crumby knowing it really hurts the environment. Hopefully these sound wave systems can be adapted to municipal water systems so as to remove the consumer as the point of failure. Really cool to see the technology that creates Chladni figures being applied to something so useful. Reminds me of how things start off as entertainment many times, and eventually make a way into an industrial application.

> Reminds me of how things start off as entertainment many times, and eventually make a way into an industrial application. I was just thinking about this phenomenon, in terms of how it runs counter to the criticism of "solutions in search of problems" and projects derided as "toys". This is a good response to those condemnations: often great ideas work in entertainment first, then industry. The canonical example from antiquity is Heron of Alexandria's automata. Nowadays, roller coasters seem like a technology that future historians will puzzle over non-utilization beyond entertainment. (The cause of course is zoning, which halted housing and transportation innovation a hundred years ago.)
