That's the premise behind the algaculture symbiosis suit designed by Michael Burton and Michiko Nitta. The symbiosis suit is designed to make food for you as you go about your daily routine. A number of tubes, placed in front of your mouth, harness the CO2 you breathe and feed it to an ever-growing population of algae which lives in the suit. Stepping outside or sitting near a window provides the algae all the sun it requires.

 

Of course, the growing of algae isn't the end-game here — it's growing enough to eat three square meals a day of the stuff. The suit debuted at a recent event at the Victoria and Albert Museum in London. There, an opera singer donned the algaculture symbiosis suit and serenaded the gathered crowd.
