The creators of the Water-Scraper believe that the effects of climate change mean it’s “only natural that we will populate the seas someday,” so they designed this sustainable structure for humans to occupy. The Water-Scraper uses wave, wind and solar power, and it even generates its own food through farming, aquaculture and hydroponics. A small forest is nestled on the top of the Water-Scraper, along with wind turbines, a garden and livestock. The living areas are located just below sea level.
In Madrid over 50% of public fountains have been decommissioned, dismantled or left for ruins. In January, the group ‘luzinterruptus’ decided to create fountains of light all over the city using over 200 small glass jars equipped with LED lights to raise awareness.

Waste-powered robots: The future of machines?
Robots power themselves on microbes, rotten food and dead insects. EcoBot-III was able to both eat and produce waste inside its lab environment.
Is Graphene the Perfect Water Filter of the Future?
Graphene - a thin sheet of carbon atoms - along with its cousin, the carbon nanotube, is one of the most promising materials discovered in a long time. It has superlative properties when it comes to strength, thinness, conductivity, optics, etc. We know a lot about, but scientists and engineers are still finding new ways to use it. The latest discovery has to do with a property of graphene that makes it superpermeable with respect to water.
