“Tibbits is working more than a tad bit with a Boston company called Geosyntec to develop a new paradigm in water infrastructure. Rather than use fixed-capacity water pipes, they’re experimenting with nanoscale adaptive materials built from the environment. 4-D printing with adaptive pipes to correct our water piping reminds me a lot of how human veins expand and contract to accommodate blood flow. The 4-D printing solution is similar. ‘Imagine if water pipes could expand or contract to change capacity or change flow rate,’ Tibbits said in a recent TED talk. ‘Or maybe [they] undulate like peristaltics to move the water themselves,’ he said.”
