I believe they store in controlled environment as well.


"According to Watkins, we have a technology called Controlled Atmosphere (CA) storage to thank for being to eat an apple whenever we please. In CA storage rooms, the temperature, oxygen, carbon dioxide, and humidity levels are adjusted to form hospitable hibernation environments for apples being stored after harvest."


Yes, I agree. The Carbon Dioxide factor is very important. Ripening fruit gives off CO2 and O2 is bad for situations where slowing ripening is the desired result. Look at old world "root cellars". They reduced the amount of O2 and the dirt absorbed a good portion of what got in. The ripening fruit that were also off gassing CO2 at the same time, and forcing the O2 out.

Fruit storage has become a science by using artificial refrigeration and forced CO2 into the storage facility for supplying fruit to all those that don't have access to a root cellar.

I still have not figured out how Costco has been able to promote CO2 filled tires as being better. It sounds like a bunch of hot air, to me.

OOOpppss.....my bad, they are claiming using Nitrogen, not CO2. Even at that....

Nitrogen gas (N2) makes up 78.1% of the Earth's atmosphere.

It's Nitrogen not C02 they promote becuse the moleculed are smaller and do not seep out of the tires as fast.

Just a bunch of BS and cash grab.

Yup. Except Nitrogen molecules are LARGER not smaller and therefor don't seep out as quickly.

The other advantage to nitrogen is that it expands more/less with temperature change. Apparently useful in airplanes that quickly transition from -35* to + 35* but not really needed in a car.

Plus if you think about it. 78% nitrogen to start. But over time the oxygen seeps out while the nitrogen is retained. After a few top-ups you'll be at 85-90% nitrogen anyway.

Is that what I smelled, I thought it was Hydrogen sulfide.

Hard to say. Forums reek of BS even on a good day :up:
