I want to believe - but I've heard too many pixie-dust science predictions to just roll over. Prove it to me - show me the math.

🤯 World’s largest 3D printer can build a small house in 80 hours

"A single-story bungalow could take a few months to build, but this printer can complete the project in less than four days.

"The university, with a longstanding relationship with the US government, wanted to demonstrate that a 3D printer could print a home with a lower carbon footprint – as the construction industry produces about 37% of greenhouse gas emissions"

🌞 400,000 ‘solar balconies’ boost German home energy harvesting capacity

"The solar balcony generates only a tenth of the power output of a rooftop solution, but it is portable if the homeowner wishes to relocate.

👉 Unlike a rooftop system that requires professionals for installation, a balcony solar system consists of panels and a mounting structure, and the assembly can be completed by anyone using the instructions provided."

Some say there are two types of concrete – cracked and on the brink of cracking. But what if when concrete cracked, it could heal itself?

The science behind it is called a ‘biofiber’, and it could revolutionize construction.

Thin, bacteria-coated fibers could lead to self-healing concrete that fills in its own cracks

Your skin heals from cuts and scrapes on its own − what if concrete could do that too?
