[The Gaijin]

This is my own pet conspiracy theory and have expounded on it here (and bored all of you) more than once.

Cheap home heating oil, not cheap gas is the bread of our modern "give them bread and circuses" mentality.

Mcmansion owners, middle income folks and oldsters on fixed incomes need this stuff by the truckload to keep warm...

If diesel cars and trucks become as popular as they are in Western Europe and Japan - they are going to put upward pressure on the cost of HHO.

Hence all of the EPA rules and the reluctance of the major automakers to sell more than a few diesel cars and light trucks...
