Jim seems to be saying quite the opposite of what you are saying. I certainly disagree with Jim: there are no conditions under which diesel is not safer than any compressed gas or liquified gas (natural gas, propane, hydrogen). Has the world forgotten the lesson of the Hindenberg already? However, environmentally speaking, diesel may not be as good as some kind of gas (propane or natural gas). I know a local company is working on converting large industrial diesel motors (16 cylinder) to hybrid fuel that use a mixture of diesel and natural gas. Lots of cost and enviromental savings. This company is designing these things to be used on generators into the 1 megawatt range. Enough to power about a 1000 houses, or a LOT of FreeBSD servers.
