This guy invented a breathing leaf that converts carbon dioxide into oxygen and will probably save the human race if we don't ignore it like we did the water-powered car.

Finally, we can breathe as much as we want.

When I was a kid, my best attempt to save the planet was me going outside to breathe directly onto trees to encourage them to turn my toxic waste into oxygen. Today, artist/scientist Julian Melchiorri has created a man-made leaf that actually does that.

He calls it a "breathing leaf" and it is a bunch of chloroplasts—the parts of a plant that function during photosynthesis—suspended in silk protein. It takes water, light, and your stupid used up air and turns it into breathable 02. This is probably going to be a really big deal.
