As soon as sustainable design innovator Yves Béhar caught wind of SodaStream’s environmentally conscious home soda maker, he had to put his creative spin on it. Featuring an earthy beech wood finish, the pared-down Source Soda Maker reflects Béhar’s love of high-tech solutions with a human element. Simply fill the carbonating vessel with tap water, lock it into place, and press the lid to release a jet of bubbles within. Powered by a CO2 canister, this device saves about 550 plastic bottles a year.
