Nitrogen preservation box

That could be potentially dangerous. Something that happens in racing circles every few years or so is a guy who doesn't check the regulator on his nitrogen tank. He goes to fill his tires, and then a day later they find him dead on the floor in the garage. What happens is that the nitrogen displaces all the oxygen in an enclosed space really quickly, and you don't realize you're short of breath because your body reacts only to an excess of carbon dioxide. That's why the OSHA regulations say that your garage bay doors have to be wide open when you're working with compressed gasses.

You'd have to do what they do with food preservation. Instead of a dedicated device that does both the storage and the gas exchange, you'd have to have a device out in the open that exchanges the gas in a specialized removable container. That would also have the benefit of letting you have smaller, more portable crates that are just as airtight as the thing you're thinking of. A transparent, locking lid would also let you put a passive O2 sensor on top of the stored items so you can see when the container inevitably leaks and needs to have the gas swapped out again.

 

It'd be ok if stored outside I think. Don't bother with it inside a enclosed space those.

 

Who stores his games outside?

 

Mh, I'm not sure what kind of games this would exactly apply to. Maybe there'd be a tiny market for a niche device such as this, but the amount of people who actually have something valuable enough to put in a vacuum safe for eternity might be quite small.

I probably wouldn't buy it even if money and space wasn't an issue and if I had MD Tetris next to Go Net and Famicom Gold Carts, I'd still just put them in plastic bags on bubble wrap in a dark chamber so I can look at them at any time.

 

you could build a nitrogen case pretty easily with a fish tank
a sheet of plexy that fits the top of the fish tank
some industrial glue and a couple of one way vales inserted into the plexy
vacuum out the air with a standard shop vac close the vacuum valve
connect the nitrogen source to the inlet valve
and let the vacuum created inside the fish tank do all the filling
you could even get low-E tintiing for the glass of the fish tank and plexy
probably do the whole project yourself for less then 200

 

Yeah, that just sounds crazy and dangerous.

No thanks
