Researchers Turn Algae Into a Material as Hard as Steel

Algae in a pond may look flimsy. But scientists are using algae to develop industrial-strength material that's as hard as steel but only a fraction of the weight.




Thomas Brück of the Technical University of Munich, Germany, and his team developed a process that uses algae oil to create carbon fibers. They're strong, lightweight materials that can be used in cars, airplanes and buildings.

Making these carbon fibers uses far less energy and produces far less carbon pollution than making concrete or steel. But that's not its only climate benefit.

Algae absorb CO2 as they grow, so when algae oil is used as a raw material for carbon fibers, the CO2 gets locked inside.

Years later, when those carbon fibers need to be disposed of, they can be ground up and permanently stored underground.

"So you have this very new advanced material where you can actually store atmospheric carbon indefinitely," Brück says.

He says scaling up will require big investments in algae cultivation. But once that's in place, this new technology could create strong industrial materials that also benefit the climate.

President Donald Trump doesn't like wind turbines.

In April, he claimed they caused cancer, and he sued to stop an offshore wind farm that was scheduled to go up near land he had purchased for a golf course in Aberdeenshire in Scotland. He lost that fight, and now the Trump Organization has agreed to pay the Scottish government $290,000 to cover its legal fees, The Washington Post reported Tuesday.

This year, three studies showed that humor is useful for engaging the public about climate change. The studies, published in The Journal of Science Communication, Comedy Studies and Science Communication, added to the growing wave of scientists, entertainers and politicians who agree.

If I were to open my refrigerator, the origins of most of the food wouldn't be too much of a mystery — the milk, cheese and produce all come from relatively nearby farms. I can tell from the labels on other packaged goods if they're fair trade, non-GMO or organic.

Some good news, for a change, about climate change: When hundreds of newsrooms focus their attention on the climate crisis, all at the same time, the public conversation about the problem gets better: more prominent, more informative, more urgent.
