New technology uses seawater to remove carbon from the atmosphere
The ocean absorbs about a third of the CO2 that humans create when burning fossil fuels. While that’s good news for the air, capturing so much extra carbon dioxide makes ocean waters more acidic, harming marine life. Enter Ebb Carbon, a startup that wants to reinforce the ocean’s ability to Read More...
This startup makes diamonds out of CO2 captured from the atmosphere
From worker exploitation to environmental degradation, mined diamonds are fraught with problems. And while synthetically made gems are marketed to be more ethical, they are often made from fossil fuels. Looking to cover all ethical bases, a startup found a way to produce diamonds that are not only Read More...
System to capture astronaut exhalations inspires Earth-based CO2 removal
When astronauts aboard the International Space Station (ISS) exhale carbon dioxide (CO2), it's removed from the air and pumped into space. Could an Earth-based version help remove greenhouse gas emissions from our atmosphere? In order to limit global warming to Read More...
