Low-flow shower heads are not a new phenomenon. They’ve been around for some time, with varying degrees of annoyance for many years. The idea of saving water while enjoying a long, hot shower has been discussed and executed in many different ways. A new $3,000 shower that recycles (and purifies) our shower water was announced earlier this month with eyes on “revolutionizing” the industry. The Hamwells e-Shower is iOS-connected and re-uses every drop of water seven times. It’s goal is to significantly reduce our water and energy usage. The question is, will consumers buy-in?
