  •  "Everything but the squeal." (7+ / 0-)

    In the old days, folks said that when a hog was butchered, you would use "everything but the squeal."  The real definition of efficiency.

    We should use such things as waste heat to heat water and turn a steam turbine--even if it is just enough to power the manager's office at the factory. We should install timers to turn off the lights in public restrooms when no one is using the facility.  We should heat a greenhouse with waste energy from some other process.

    Very good to throw thought at a problem, instead of money!

    To say my fate is not tied to your fate is like saying, "Your end of the boat is sinking."--Hugh Downs

    •  The War Against Imagination (6+ / 0-)

      Diane di Prima wrote an anti-war poem in the 60s™ called "Rant" in which she said,

      The only war that matters is the war against the imagination
      The only war that matters is the war against the imagination
      The only war that matters is the war against the imagination

      We've been engaged in that war all my life and, at least since the Reagan Revolution, the forces of unimagination have been winning.  It's way past time to take back our dreams.

    •  Waste heat has been and is frequently used (5+ / 0-)

      as described in this diary. I have numerous books on industrial technology, written from the late Victorian ear to the 1990s.  You can read one of them without falling over several mentions of the use of byproducts and waste heat.

      The steel industry in the U.S. has lagged in this regard. Back in the later 1960s and 1970s, the U.S. industry had fallen behind the rest of the world in steel making technology, sales of U.S. produced ferrous alloys was dropping.

      The industry and the steel worker unions lobbied for protective tariffs, "to give them a chance to modernize." Tariffs were imposed in 1974 However, they did little modernization, but increased profits instead.

      This caught up with them in the later 1980s ind 1990s.  Failure to modernize combined with high labor cost, in part due to that failure of updating and to unions resisting improvements that would reduce manpower needs, priced the big U.S. steel producers out of the market. Note that in this period Europe, with its high wages and tax systems, was the major external supplier of steel to the U.S. Tariffs were reinstated in 2002, again due to union and industry pressure, but dropped the next year when found illegal under international agreements.

      Note that two of the examples gmoke gives are steel industry - coke plants and metallurgical grade silicon for silicon steel.

      Part of the newer technologies included continuous casting and the use of electric arc furnaces for recycling scrap, as well as better use of waste heat.  This lead to the growth of "mini-mills", at first exclusively scrap recyclers, that were much more efficient the the older plants in the U.S. The established U.S. manufactures choose not to improve their plants, make them more efficient, because it cost money up front and because the unions fought such improvements.

      •  Silicon (0+ / 0-)

        The silicon plant is for refined silicon, the raw material for computer and solar chips not steel but you put your finger on the nub of the issue:  these are technologies and techniques that we know how to use.  The problem is that we don't use them.  The question is how to do we change that pattern and begin to improve the efficiency of our systems all the way down the line.

        Casten had other examples of CHP that had to do with district heating (and cooling) in Trenton, for instance.
