2014-8-11Interesting. I use gas cylinders on a daily basis, and the lack of a wall clamp makes me cringe, especially with a dog around. I’ll be honest, I’m surprised you could buy a CO2 cylinder easily, because I remember needing it for an experiment once (lab grade, not “edible-grade”) and it being a bit of a hubba-baloo to get it.

Autogas - Wikipedia

2018-9-9Autogas is the common name for liquefied petroleum gas (LPG) when it is used as a fuel in internal combustion engines in vehicles as well as in stationary applications such as generators.It is a mixture of propane and butane.. Autogas is widely used as a "green" fuel, as its use reduces CO 2 exhaust emissions by around 15% compared to petrol.One litre of petrol produces 2.3 kg of CO 2

Here’s what real science says about the role

2018-3-12Commenters on my blog also often claim that since the concentration of CO2 in the atmosphere is so low compared to that of water vapor, also a greenhouse gas, it could not possibly play the role
