Would any of these work as a Co2 tank?

Could any of these tanks work as a pressurized Co2 system for a planted tank?

10 GALLON AIR TANK

A normal 40lb grill/BarBQ propane tank

A fire extinguisher

Also, could they be mounted horizontally?

Go to your local welding supply shop. Tell them you want a 10lb (or 20lb) tank. You'll pay about $40-50 for the tank. When it's empty you take it back, they fill it up, and if you've got $5-10 the guy will just smile and fill it.

BTW, the answer is no, those tanks will not do. Bite the bullet.

That's a cheap price! In Houston, I've got to go from the south side of the city up to the north side (about 40 miles one way) to get a $90 five pound tank. It's about 8 dollars to refill and they just do an even swap so there's no waiting. I wish I could get a 10lb for $40-50. And closer to my house!
