Please allow a digression. In 1974 I was an armed guard at NW Bell, downtown St. Paul. I was warned that if a terrorist struck, that was where. Seven floors of the building were relay switches giving off sparks when people dialed their phones. In the early eighties I joined the effort to promote an extended fiber optic communications grid that allowed "micro-computers" to communicate. Prof. Otto Schmitt (inventor of digital electronics at the U of M) added that such a communications grid would be immune from EMPs (electro-magnetic pulses) from nuclear weapons. Our modern communications grid is now largely very secure (except for M$ software) and efficient. Over the last decade (at least) I have promoted fuel cells and local fuels (methanol) with the same purpose. Our energy infrastructure is an open target. God help us if these monsters should hit a nuclear facility. Our political leadership is as protective of the status quo as it was of "super-computers" in the early eighties and is more a problem than the technology itself. Several fuel cell companies plan big boosts in manufacturing. Most publicity is focused on fuel cell cars. But the big, near term fuels cell market is stationary fuel cells for large buildings. Manufacturing plans are in the hundreds of thousands of fuel cells per year. Every large fuel cell will need a computer controller, as these are complex chemical and electric devices. Linux is an outstanding starting point for a fuel cell controller's software. I wish I could claim to be an expert at everything, or anything. I've gotten some outstanding leads from this (TCLUG) group. This winter I should have a better playground (laboratory) to try fine tune some controller software. Your ideas are appreciated.
