Meanwhile, I have been whimsying on a side issue. It goes like this:

You get a whole bunch of machines - earthmovers, rigs, derricks, and you extract fuels. You build more machines - turbines and generators. You send electricity out over the world.

You buy furhter machines - a tour bus, some lorries. Amps, lights, electric instruments.

Then you start a band and what do you call it? "Rage against the Machine"   !!!
