Growing food in space is a lot harder than you might think. Because of ethylene. gas that all growing plants generate.
Just as in a cold storage, in a spacecraft, ethylene build-up kills destroy the plants and vegetables it would normally ripen. As well as plant to plant cross contamination, NASA needed to develop technology to destroy the gas so food could be grown and enable deep-space travel to move forward.
The Mission: clear the air of ethylene gas and VOCs.
It had to be virtually maintenance free, take up very little space, produce no Ozone or any other harmful byproducts, use very little power, and eliminate unwanted ethylene.
A unique air purification technology was invented.
A hybrid nano-technology, based on the evolution of photocatalytic oxidation (PCO). It uses no filters. It deconstructs organic gasses at a molecular level on contact, converting them to CO2 and water vapor.
What it was done for the space program, now can be done on your cold storage and perishable retail business too.
