Scientific sculptures reveal the hidden beauty of algae

[UK] Sawa is a British architect and materiologist, and she creates elaborate sculptures out of farmed algae, tubes, and glass vessels. Altogether, it looks like the stuff of a mad scientist’s lab. But these are not just aesthetic objects. With further research, they have the potential to harness green energy.

Sawa’s project, called Algaerium, grows algae in her own makeshift lab. She describes the process:

“The design specially focuses on two different types of algae’s photosynthetic metabolism. Green algae convert light energy and CO2 into O2 and biochemical energy (biofuel) and white algae (bioluminescent) produce its bioluminescence from photosynthesis. The photosynthesis of green algae generates a responsive colour system. The water is CO2 sensitive and changes to purple from yellow as the algae photosynthesize.”

Algae already figures prominently in the commercial and industrial sectors. It’s used in food, fertilizer, dye, bioplastics, and pharmaceuticals. The U.S. government recently invested $25 million in algae fuel research. And studies have shown that it can help generate electricity. But Sawa wants to exploit it in a quieter way: at home. “Algaerium expands the industrial scale of algaculture to a new scale: bringing new green presence into our urban living,” she says.

There’s just one problem, as Sawa readily admits: The technology will take a while to implement. But when it is ready, energy generation will never have looked so beautiful.
