Graphene is a unique, single-atom-thick sheet of pure carbon, akin to graphite but more flexible, strong, and conductive. Start watching the video from 2:30, after lots of teaser intro.
Thought you'd appreciate this update on actual construction projects that incorporate graphene into materials like concrete that no longer needs rebar steel inside (4:35,) and street paving less prone to cracking and potholes (4:50.)
2:54 concrete that's stronger, and more importantly, gains that strength earlier. (The rate of a construction project is often stymied by the slow curing process taking weeks - https://en.wikipedia.org/wiki/Concrete --> production --> curing )
3:20 world's first graphene-concrete hybrid construction - a gymnasium floor. They chose the unimpressive name "Concretene" for the product. The new material is 30% stronger and resistant to cracking (3:35).
5:30 graphene can be incorporated into liquids like paint to increase resilience and corrosion-resistance (the latter reduces the need for environmentally-toxic zinc) on the surface of bridges and wind turbines for instance.
6:02 Achieving graphene production at scale has been a much-needed breakthrough for the material, e g. https://www.graphene-info.com/researchers-demonstrate-new-technique-mass-producing-high-quality-graphene
Adopting this new material may be slow (3:59) because of arcane, stodgy, misoneistic regulatory bodies that must approve it, so it may take 5 years to gain wide acceptance (6:43)
Investing in graphene - many companies claim to be working on graphene. But a few companies working on large-scale production of graphene are under the ticker symbols APGMF, HDGHF, GPHBF, ARRXF, DTPKF, FGPHF.
Caveat emptor - these are penny stocks in the early phases of these companies and are highly volatile.
