High humidity means high levels of water vapor in the air ― the vapor that condenses and becomes visible as “fog” on windows of air-conditioned cars and buildings on steamy summer days. “This was clear evidence that water in the atmosphere can accumulate electrical charges and transfer them to other materials it comes into contact with,” Galeeck explained.
A new way of removing carbon dioxide from a stream of air could provide a significant tool in the battle against climate change. The new system can work on the gas at virtually any concentration level, even down to the roughly 400 parts per million currently found in the atmosphere.
