"The dual use of the word gas in the USA has confused me at times"

Dual?? Try three uses.... I was very concerned when an American friend told me she had gas and was sorry about it. Having come across its use as 'petrol' I was shocked to think of my friend having to 'pass' her gas....


Although, maybe there's something the biofuel inventors should be looking at.... how much of that 'gas' is there in the world and how can we harness it?
