George , havent got time to read your links ( 2am here , just got home from a 50 litres of diesel road trip , arggh) , i will read , as i was googling re the possiblty of using vegie oil instead of 2 stroke oil , which is dam expensive . Guess what , 2 stroke petrol engines orignally ran on vegetable oil . however they carbon up using it quite quickly apparently .
i will get round to trying it anyway , on a chinese $ 100 generator .
Vegetable oil is a separate topic. I know very little about it. However, I do know about biogas, having made it in Kenya and Nigeria.
I think it interesting that in Sweden they are running a single rail car on biogas. The item appeared on the late night BBC News in depth programme Newsnight. They did not explain what kind of motor was being used. I think probably it was a modified diesel, but petrol engines can also be used. I think fuel cells may be the final choice, but I don't think large ones are easily available yet. Hydrogen will certainly be used in fuel cells.
I did know a farmer in Kenya who used biogas for static engines. He used a generator for his farm electricity and a static pump to lift water from the dam for the farm and the household. However he hadn't adapted any vehicles to use it.
There has been some discussion in Britain of hydrogen fuel cells for locomotives. They would be used on lines that are not busy enough to be worth installing overhead electric power. They would probably have and advantage over road lorries.
There are people in Britan who use vegetable oil from chip shops and other kitchens to run diesel engines. One is a canal boat; others are vans. However, they are supposed to pay tax on the oil. People who bought new vegetable oil were caught last year and fined for not paying tax.
In Wales the Ffestiniog Railway has always run its steam engines on oil (nasty smell - I don't like it). They have a tanker that goes round to garages and workshops and collects old sump oil. I think the Forestrty Commission doesn't want coal burning locomotives in their forests. I find theiur trains always give me a slight headache and the smell isn't right.
