How a Massachusetts Man Invented the Global Ice Market

An anonymous reader writes with the story of Frederic Tudor, the man responsible for the modern food industry. "A guy from Boston walks into a bar and offers to sell the owner a chunk of ice. To modern ears, that sounds like the opening line of a joke. But 200 years ago, it would have sounded like science fiction—especially if it was summer, when no one in the bar had seen frozen water in months. In fact, it's history. The ice guy was sent by a 20-something by the name of Frederic Tudor, born in 1783 and known by the mid-19th century as the "Ice King of the World." What he had done was figure out a way to harvest ice from local ponds, and keep it frozen long enough to ship halfway around the world.

Today, the New England ice trade, which Tudor started in Boston's backyard in 1806, sounds cartoonishly old-fashioned. The work of ice-harvesting, which involved cutting massive chunks out of frozen bodies of water, packing them in sawdust for storage and transport, and selling them near and far, seems as archaic as the job of town crier. But scholars in recent years have suggested that we're missing something. In fact, they say, the ice trade was a catalyst for a transformation in daily life so powerful that the mark it left can still be seen on our cultural habits even today. Tudor's big idea ended up altering the course of history, making it possible not only to serve barflies cool mint juleps in the dead of summer, but to dramatically extend the shelf life and reach of food. Suddenly people could eat perishable fruits, vegetables, and meat produced far from their homes. Ice built a new kind of infrastructure that would ultimately become the cold, shiny basis for the entire modern food industry."

      Old ways of doing things often hang on an unexpectedly long time because a mature technology has the advantages of ubiquity. People are comfortable with it, all the kinks have all been worked out, and its popularity gives it a huge structural cost advantage.

      You can't think in terms of how expensive it would be to have a 50 lb block of ice delivered to your doorstep today. The *marginal* cost of having ice delivered is nil when everyone on your street is getting it. Everyone had an actual "icebox", and since it had no moving parts it never needed servicing or replacing. So when electric refrigerators became available it was a choice of keeping your perfectly good icebox with its reliable, regularly scheduled ice delivery, or buy a cranky, complicated, expensive piece of machinery that would pay for itself just in time to need replacing. If the ice industry killed itself by shipping polluted ice, it's probably because they couldn't expand their supply to meet demand.

      I'll bet the grandchildren of kids learning to drive today will find the whole concept of a massive, truck-based gasoline distribution network absurdly complicated. But it works because it's massive, and because it's ubiquitous we assume it is simple -- which it is on the consumer end. On the production end it is fantastically complicated and labor intensive.

      Speaking of the Boston ice industry, I live a half mile from a 20 acre (8 ha) pond that supported a major ice operation in the 1800s. Pictures show men harvesting blocks of ice eighteen, even twenty-four inches thick for shipment around the world. In the non-winter months the companies operated water-powered mills. Ice was a classic case of exploiting slack resources. Ice meant no head for the water powered mill, and an idle workforce. So electric refrigeration wasn't the only pressure on the ice industry: electric factories would have raised the price of winter labor.

      Today that same pond never gets more than a couple of inches of ice, even in last year's "polar vortex" event -- you can't make ice that thick in a couple weeks, you need a cold winter that starts early and doesn't let go for months. When I was a kid this pond iced over in December. Now it ices over in Janurary, or Feburary, or some years not at all except for the lee end. In January I can fish from my canoe on ponds where I would once have been ice-fishing.

    Combustion engine driven compressors are similar to electric motor driven ones, but are more complicated and certainly have plenty of moving parts. Adsorption/absorption refrigeration systems have fewer moving parts, as they use heat as the main driving force and so don't have compressors. But they still have moving parts like pumps and fans, and they are completely dissimilar in design to mechanical compressor driven refrigeration.

    My old 1975-era RV fridge had no moving parts at all, no pump, no fan. Just a propane driven pilot light which switched off & on as it heated the ammonia in a sealed system. The ammonia circulated passively. The fridge had to be kept in a more or less vertical orientation for the circulation to work properly. Too much off level, it wouldn't work. When the RV was rolling down the road, the orientation of the fridge was less important, the constant shifting back & forth of the fridge would allow the refrigerant to circulate quite well. Its main point of breakdown was the pilot light / thermocouple mechanism, kept either getting dirty or corroded, otherwise it was extremely reliable. The propane supply could be switched off and the fridge could run on "shore power" - 110VAC when the RV was plugged in. The 110VAC was simply used as a heat source, again, no pumps, no fan, electricity was solely used as a heat source.

    More formally, the rate of heat absorption of ice melting at a rate of one short (i.e., not metric) ton per day. It's about 12,000 Btu's per hour or 3517 watts.

    Note that this does not include any heat required to bring colder ice up to the melting point, or any heat added after the melting takes place. The power required to drive an air conditioner equals the number of tons, times 3517 watts, divided by the coefficient of performance of the unit (which is in the neighborhood of 3 for most AC installations). So a one-ton unit with COP 3 will draw a bit over a kilowatt while it's cooling; what you see on your electric bill will be that, times the fraction of the time that the thermostat commands cooling on.

    My 2011-era RV fridge is similar (no moving parts except for the fluid going around), except that instead of using a pilot light, it uses electronic ignition (which means it not just needs propane, but battery power to keep your stuff cooled.) I would prefer the 1975-era style of a pilot light, but I guess times change.

    It has two disadvantages: It does cool, but relatively slowly, because the refrigerator part doesn't have any air circulating in it. A small fan in there (Valterra sells on that runs 4-6 weeks on two "D" cells) works wonders. The second is as described above. The newer fridge requires being within three degrees of level when stopped as well.

    For a house, with fridge prices going up, it used to be that a gas fridge was just too expensive unless someone just had no access to power, such as a backwoods cabin and a propane tank. Now, one can buy a decent gas fridge which uses no electric (except for the option of having the light inside the fridge come on) for a decent price. It may not have a TV on the front or allow one to Twitter what veggies are stashed in the crisper, but it keeps stuff cold regardless if the power is on or not.
