Using NASA-Patented technology, designer Francesco Codicè has designed a new concept for purifying air on trains.
Trains provide a greener alternative to transportation than driving or flying, but US trains could definitely use a design update. Codicè's AirTrain is a modern and elegant solution to the often stuffy and stale air of the indoors. AirTrain purifies air with live plants and recycled rain water.
The design includes an exterior rain collection system for watering the plants. Not only purifying the air, the plants provide a more aesthetically-pleasing environment for travelers.
