Moss cabin

Inflight bryophytes

Plants like mosses could have wonderful impact in extreme environments. Aside from their potential to produce cheap and environmentally friendly electricity, they offer other benefits. 

Illustrated on the quite extreme setting of aircraft cabins, mosses would improve air quality due to lowered carbon dioxide levels, increase humidity due to “plant sweating”, and - crucially - provide a visually and tangibly calming experience.

You might wonder about the aircraft cabin. Fact is, it’s a small enclosed space most densely packed with people over a prolonged period of time. And airlines don’t exactly give us the best quality air, because it’s expensive to split ozone into oxygen and provide passengers with clean, fresh air at high altitudes.

It is important to bear in mind, however, that the so-called Environmental Control Systems of aircraft, which manage air flow, are primarily designed to keep us alive. Nonetheless, the suboptimal air quality on board can give many of us quite literally a headache. 

The main issues are increased carbon dioxide levels and extreme dryness (these have been thoroughly researched and documented). Furthermore, many passengers suffer from flight anxiety. So you can see how a bit of moss could make a big difference.
