Engineers at the University of Maryland have found that porous types of wood from trees like poplar and pine can greatly increase the efficiency of water-to-steam conversion under sunlight. The findings, published November 15 in the journal Joule, could be used in a simple and inexpensive biodegradable device for water purification.
“I think there are many, many materials that can be used in solar steam generation, but wood really stands out in terms of performance as well as cost,” says senior author Liangbing Hu, Associate Professor of Materials Science and Engineering in the A. James Clark School of Engineering and the University of Maryland Energy Innovation Institute. Read more
