I think this is a bit of a sham actually. The pricing for sodastream "Chargers" aka CO2 bottles is nearly downright obscene.
One of those "60L" cylinders BTW sells for $43.75 CAD on Amazon... And the user is just encouraged to recycle them instead of recharge them. When you work it out, it works out to a $1.37 per litre.
Whereas, a 50 lb CO2 tank costs about $200 and costs $80 to fill full of CO2.
You can make 70 litres of pop on a pound of CO2, so a 50 lb bottle would make
3500 litres of pop.. So, for the cost of the tank and the CO2, it would cost you
$0.08 or 8 cents per litre.
When I can shove a 50 lb CO2 bottle behind the fridge and hook it up, sign me up.
I kind of figure that even if I drank 2 litres of pop about once a week, it would take me roughly 34 years to empty that tank.
