Can Forests of Artificial Trees Stop Global Warming?
As climate change accelerates, scientists keep coming up with increasingly fanciful schemes to fight it. Earlier this month we took a look at a plan to deploy ships that spray climate change-battling clouds, and now comes word from a study by the Institute of Mechanical Engineers that forests of artificial trees could potentially soak up carbon dioxide. According to the study, 100,000 synthetic trees spread across the U.K. could remove the CO2 emissions of all cars, trucks and buses in the country. The trees, which are two-thirds as tall as average wind turbines, are coated with materials that absorb CO2. Once the trees capture carbon dioxide, it can be stored underground in empty oil and natural gas reserves. It’s not a cheap or problem-free plan–each tree costs $24,313. And what happens to the stored CO2 in the event of an earthquake? But the fake trees are thousands of times more efficient at capturing CO2 than those pesky real trees. // IME engineers also recommend lining building
