MIT's Breakthrough Hydrogel Makes Water From Air w/ ZERO Power

簡介：

Air water generation systems almost seem like magic, pulling clean drinking water right out of the air. But it's typically incredibly energy intensive, and suffers from dryer air. But a team of researchers at MIT have developed a new hydrogel that absorbs water out of the air like a sponge during the day, and releases it at night. The most amazing part, is that it requires no energy of any kind, and it can be reset each and every morning, without any intervention. Obviously this would be a game-changer in the fight for clean drinking water, but does this tech really live up to the hype? 00:00 - Intro 00:40 - What MIT Made 00:53 - Why Does This Matter 01:39 - Desalination 02:02 - AWG 02:50 - How it works 05:34 - Why this Could Be A Game Changer 09:22 - The Challenges that Stand in the Way 10:58 - Cost of Replacing a single Desalination Plant 11:53 - The Problem With Hydrogel
