Algae tiles trapping carbon? That's hard to believe. How does that even work in a real house? You walk on it, spill stuff, and it's supposed to just suck up CO2? Most floors just sit there doing nothing. This sounds like a gimmick from a sci-fi movie. I mean, do you have to water it or something to keep it alive?
Yeah the sci-fi movie feeling is real! I felt the same until my friend installed some. You don't water it, it's sealed in, and honestly seeing the green underfoot just makes it click.
