VergeLabs, an architecture and design practice based in the United Arab Emirates founded as a partnership between Ginger Krieg Dosier and Michael Dosier, brought some of that magic to concrete with their development of Glowcrete.

The researchers used phosphorescent pigment in two ways to produce glowing concrete: they added the pigment to expansion cement, the pigment, when distributed unevenly, left a glowing trail that served as a record of the mixing process; and they also added the phosphorescent pigment to the concrete as aggregate. The even distribution of pigment in the second case creates a uniform distribution of light emission.

In each case, as the surface of the concrete weathers and erodes, new phosphorescent aggregate is exposed, which extends the lifespan of the luminescence (Source: Vergelabs).  I’d like to learn more about the phosphorescent pigment the researchers used – I’m not sure how long it lasts or whether it’s toxic (although I’d imagine the answers to those questions are: not very and yes).  That being acknowledged, I can so clearly imagine this material at the bottom of a swimming pool or fountain, or even on the underside of an unfinished concrete slab – pure magic.

WU XING:

I have filed glowcrete under Earth (concrete) and Fire (glowiness!)

NASA certainly thinks so, and to that end they have awarded four research groups a cool $16.5 million* to make airplanes run more efficiently, quietly, and less dangerously than ever before. One of the groups is a Cessna and GE team, and they are developing a “Smoothing, Thermal, Absorbing, Reflective, Conductive, Cosmetic” skin for planes.  The self-healing skin, which has been dubbed STAR-C2 for short, protects metal tubes with wings against a host of horrible threats like impact damage, lightning strikes, electromagnetic interference (EMI), temperature extremes, and it insulates the cabin from noise (Dillow). If you’re like me, you wouldn’t be surprised to learn that STAR-C2 also makes a delightful coq au vin and regularly vacuums the drapes without anybody asking. (Okay, I made up that last part, but that would be nice, wouldn’t it?)

The research team is working on technology that would make its way into airplanes three generations from now (equivalent to about 25-30 years).  It will be worth the weight: “in the final report on its original N+3 study, the GE/Cessna team calculated that the new outer skin made from conductive film and energy-absorbing foam would more than halve the weight of the various measures that now must be taken to protect composite materials from environmental hazards” (Warwick). The material would be self-healing if punctured or torn, but it would also be designed to show damage so that any problems would become apparent to trained inspectors on the ground.

I don’t think the researchers should stop at airplanes. I want to clad entire buildings in this stuff! I don’t see a single benefit that wouldn’t make a building function better, and we have nearly three decades to figure out how to bring the cost of manufacturing it down to something reasonable. I’m excited!

I am filing STAR-C2 under metal and wood, because it enjoys properties of both elements.

*This is a reference to the following passage in Great Expectations by Charles Dickens, which for some reason stuck in my head when I read it in 9th grade:

“I never discovered from whom Joe derived the conventional temperature of the four thousand pounds; but it appeared to make the sum of money more to him, and he had a manifest relish in insisting on its being cool.”
