A New Energy-Efficient Hydrogel Pulls Water From Air

Cars That Think

Using a new kind of hydrogel material, researchers at the University of Texas at Austin have pulled water out of thin air at temperatures low enough to be achieved with sunlight. Atmospheric water harvesting draws water from humidity in the air. The material is a hydrogel, a polymer network that naturally retains a lot of water.

Tech: Protecting EV Batteries from Corrosion

Clean Fleet Report

Car battery corrosion occurs when the sulfuric acid inside the battery releases hydrogen gas. Sometimes, CCT involves immersing the materials in water. A corrosion-related aim during these tests is to see whether water can enter various parts of a battery or other EV components. Tech: Users Expect More from Batteries.
