Biomanufactured brick needs no firing, may be big deal

Biomanufactured brick needs no firing, may be big deal

Then again, if Calla lilies replaced each new brick on the planet, it would reduce carbon-dioxide emissions by at least 800 million tons a year. But we’d also be living in a world without useful new bricks to build stuff with. It is probably reasonable to expect that Dosier’s “Bacteria Bricks” will fare better as a construction material than Calla lilies, but whether they are truly comparable to conventional masonry in mechanical properties, durability, and weather resistance still remains to be proved. Also, her bricks take weeks to harden, compared to traditionally-fired bricks which can be manufactured in two days.

I have been reading the Picture of the Day feed from Wikimedia Commons for about a month, now, and it is fast becoming one of the best parts of my daily newsreader experience. Every day there’s a gorgeous new publicly-licensed photograph pre-selected for quality by a vote amongst Wikimedia community members.

That’s how I happened upon the work of German inorganic chemist and photographer alchemist-hp (English-language page). She or he takes amazing photographs of element, mineral, and chemical samples and has a stated goal (badly translated by yours truly) “to create special pictures of all naturally occurring elements.”
