Shave and a Haircut

 

Two bits! There, that feels better now, doesn’t it? A sense of completion and the comfort of familiarity. The phrase “two bits” indicates twenty-five cents specifically, and can also mean something cheap generally. The digital currency bitcoin apparently derives its name from the old fashioned uses of “bit” to indicate parts of a dollar or other currency. At the current exchange rate of around 15,000 dollars to one bitcoin, however, a bitcoin itself represents anything but parts of a dollar. Quite the opposite.

From the 1988 film Who Framed Roger Rabbit, the irresistibility of finishing off “Shave and a haircut, — —-“.

The record high valuation of bitcoin may not stand for long, and in six months one bitcoin may be worth 30,000 dollars or it may be worth 150 dollars. No one knows for sure, and that’s what is fueling a lot of argument and speculation. High amounts of speculation in the market are what inflates a bubble, and the question with bitcoin is whether it is indeed a bubble and when it might burst. That generates more speculation. More small investors buy into the market. Historically what has happened in such cases is that something happens, a large investor or two gets spooked, dumping shares on the market, a selling panic ensues as everyone tries to get out of the market while the watch the value of their investment plummet, and that’s it, the bubble burst.

Bitcoin or something like it will be around for as long as there is an internet and a demand for a monetary barter system which is decentralized and doesn’t involve significant charges going to middlemen such as banks or credit card companies. As more people use digital currency and more merchants accept it in transactions, the volatility of its valuation will settle down. Tulips are still around, after all, and people still value them, just not to the unrealistically high degree they did when the bulbs were novel. The long term problem with digital currencies generally, and bitcoin in particular, will be in decreasing the horrendous energy demands of mining them and, to a lesser extent, processing transactions. The electricity demands of mining bitcoin are now equivalent to those of Serbia, and will soon be on a par with Denmark’s electricity use.

Discussion of whether the current valuation of bitcoin represents a bubble often refers to Charles Mackay’s 1841 book Extraordinary Popular Delusions and the Madness of Crowds, and particularly to Chapter 3, “The Tulipomania”.

Much of the mining occurs in China, using electricity generated by coal-fired power plants. At a time when combating the effects of global warming is becoming a top priority, the mining of bitcoin could present an ecological catastrophe when it reaches the same level of energy consumption as that of the entire industrialized world, as it is predicted to do in the early 2020s. The digital currency genie is out of the bottle, and there’s no stuffing it back in. That leaves two options, or a combination of both – finding more energy efficient ways of mining digital currency, or using more environmentally friendly energy sources, such as solar.


The solar energy option is immediately attractive because it would help defray installation costs of solar arrays more quickly and because poorer countries, which are generally nearer the equator and hence in sunnier climes, could see income from a source that is neither environmentally nor socially destructive the way production of sugar or other cash crops has been for them. Puerto Rico, the United States territory that recently had its conventional power grid devastated by Hurricane Maria, could benefit by rebuilding with the intention of using solar energy at least partially for the profitable production of digital currency. Surplus energy from the arrays built with money from bitcoin mining would power homes and businesses at subsidized rates for people who could not afford it otherwise in very poor parts of the world. Smaller, locally owned solar arrays would be a better way to produce power because of the inefficiency of transmitting solar power long distances either in the form of direct current, or after inverting it into alternative current. Decentralization of the means of production would also serve to keep power and money in the hands of locals.

Should you invest in bitcoin? That depends on your outlook. In the currently volatile market, investing in bitcoin should be treated like gambling. In other words, don’t invest any more of your government backed (in the United States the currency is actually backed by the Federal Reserve System, a private institution of the banking industry, though it is insured by the federal government) currency than you can afford to lose. For some people that can be quite a lot, but for most people that would amount to very little.

Should you get involved in bitcoin mining and processing of transactions? At the current valuation of bitcoin, that could be quite profitable. Tomorrow its valuation could drop below the cost of the electricity required to mine it. At any rate, the “mining” simile is somewhat inaccurate, since in a comparison of the digital currency market to real world mining, the people with computer equipment engaged in its production and in the processing of transactions are actually more like the merchants in a nineteenth century American mining town who sold goods to the miners who were hoping to strike it rich.

The opening scene of Powaqqatsi depicts working conditions at the socially and environmentally disastrous Serra Pelada gold mine in Brazil. This 1988 film by Godfrey Reggio, with music by Philip Glass, is the second in his Qatsi trilogy of meditative documentaries.

A very few of those miners struck gold, and most went bust, while the merchants usually did consistently well, a few becoming household names still known today, like Levi Strauss. If you do get involved in bitcoin “mining”, it might help to connect the equipment to a solar array rather than the conventional power grid, because then when the bubble bursts and the valuation of bitcoin drops to the floor, you can possibly still operate at a profit when others cannot, or at the very least you will have an inexpensive, environmentally friendly source of power for your other ventures.

Strange Bedfellows

Trinculo:

Legg’d like a man! and his fins like arms! Warm, o’ my troth! I do now let loose my opinion, hold it no longer: this is no fish, but an islander, that hath lately suffered by a thunderbolt. [Thunder.] Alas, the storm is come again! My best way is to creep under his gaberdine; there is no other shelter hereabout. Misery acquaints a man with strange bedfellows. I will here shroud till the dregs of the storm be past.

― William Shakespeare, The Tempest (Act II, Scene ii).

After Hurricane Irma tore through Florida earlier this month, some stories surfaced about Florida homeowners with solar panels being unable to use their power in the power grid outages that followed. Like many stories, there was some truth to them, but not the entire truth. Due to intensive lobbying from utility companies, Florida has enacted more obstacles to solar energy than most states, despite the fact that its weather and latitude make it better suited than most to take advantage of solar power. Homeowners with grid-tied solar panel arrays without batteries or transfer switches were legally barred from using their solar power while the grid in their area was off line.


That in itself is not unusual compared to arrangements in other states, and should not have been the source of stories making it sound as if Big Brother was interfering in individual initiative. The problem was the stories focused on that part while at the same time ignoring the real story of how Florida legislators have systematically made business difficult for the solar power industry. It is usual practice to ensure grid-tied systems have safety measures in place such as transfer switches to prevent power from back-feeding on the grid lines and endangering utility workers as they try to restore electrical service. In Florida, however, it appears legislation has been enacted at the behest of the major utilities to go beyond this to ensure that grid-tied solar power systems could not be legally used at any time during a general power outage.

So there you are sitting in the dark after Hurricane Irma came through, just like all your neighbors, despite the array of solar panels on your roof. If you had disassociated your solar array from the grid entirely, you might have had better luck, though that would depend on local building codes or homeowners’ association rules. But since you tied into the grid with your solar array out of economic necessity and convenience, you may find out belatedly you signed a bargain with the devil. It’s like that natural gas powered fireplace which turns out to be useless when severe winter weather has cut off all services. Lighting candles won’t do enough to keep you warm.

The invidious corruption of the Florida utility laws, pervaded as they are by money from the Koch Brothers and entrenched fossil fuel interests, has had the unusual effect of forging an unlikely coalition of Tea Party conservatives and environmentalists, known as the “Green Tea” movement. The Tea Partiers are motivated by their distaste for government telling them how they can power their own homes, and tilting the playing field against them should they decide to sell surplus power on the open market, all because of the undue influence of utilities on the government. Environmentalists decry the same government corruption, but see it as unfairly limiting options for homeowners to leave a greener footprint, besides getting in the way of individual exercise of freedom.

The 1962 film Lawrence of Arabia, directed by David Lean and edited by Anne V. Coates, had many great moments, and this match cut from flame to sun is one of the most renowned.

Florida is an excellent test case for how we will cope with a warming climate, much as some people don’t want to look at it that way. Florida is hot and humid. Before the invention and widespread use of air conditioning in the twentieth century, Florida was lightly settled precisely because of its challenging climate. Since the middle of the twentieth century, Florida’s population has boomed. Florida’s energy use is 40% higher than the national average, largely because of the extensive use of air conditioning. Look at Puerto Rico now in the aftermath of Hurricane Maria. That could be Florida in a worst case scenario, which the state dodged as Hurricane Irma played out, as opposed to how an earlier forecast showed it might work out. Considering all that, it seems making solar power easier for all homeowners to implement rather than more difficult is the sensible option, no matter the arrangement of strange bedfellows.

Racing Ahead

 

In the 1965 comedy film The Great Race, loosely based on a 1908 race around the world, the lead characters drive racing versions of gasoline powered internal combustion engines. That the earliest cars used gasoline would seem to be without question considering how things developed through the rest of the twentieth century. It comes as something of a surprise then to learn that electric cars were quite popular in the early years of motor vehicle development, and it was an electric car that won the first closed circuit automobile race in the United States, in 1896.

Halfway in their race around the world, the characters portrayed by Jack Lemmon, Peter Falk, Tony Curtis, and Natalie Wood are marooned on a melting ice floe in the Bering Strait. Though certainly unintentional in 1965 when the film was made, there is some irony to their situation given the perspective of today’s warming climate.

As anyone can tell, electric cars all but disappeared until recently, as infrastructure and cost improved for gasoline engines in the early twentieth century, overtaking the electric option by 1920. The price of oil went down, giving a boost to the market for gasoline engines, while the crude state of battery technology limited the appeal of electric cars. Environmental impacts were not even a factor in the equation for most consumers or manufacturers until late in the twentieth century. Even then, the initial assessments of the impact of vehicular pollution was limited to local problems such as smog. It wasn’t until the last decades of the twentieth century that at first scientists, and then the public, looked at the larger impact of tailpipe emissions on the global climate.

Now, in the early twenty-first century, after some halting steps by manufacturers to reintroduce electric cars, it appears they are gaining in popularity, particularly in places like China which face deadly levels of air pollution. Battery technology, the Achilles heel of electric cars, has made great strides lately. A question that doesn’t crop up often enough, however, is whether electric cars are as environmentally friendly as the manufacturers would have the public believe they are. In many cases, electric cars still run on power generated by burning fossil fuels, it’s just that they give an illusion of green running because they’re not emitting noxious fumes. The noxious fumes are instead displaced to a coal or natural gas fired power plant more or less many miles away. Out of sight, out of mind.

The batteries in electric cars don’t present as big a problem from an environmental standpoint as they used to, now that up to 98 percent of the materials are recycled. To make an electric car run truly green, the power source used to charge its batteries needs to come from renewable generators like wind and solar. Since most air pollution comes from gasoline internal combustion engine exhausts, it stands to reason that a major switch over to electrically powered vehicles running on renewable energy will make the single greatest impact on reducing air pollution, and with it the particulates and gases that are contributing to global warming.

Organizations like NASCAR and Formula One racing could do their part in flipping the switch by turning all or part of their circuits over to electric cars. Besides being a spectator sport, car racing has always served as a proving ground for manufacturers. The big racing organizations are still clinging to the old technology, which may be popular with fans who enjoy the noise and familiar smells produced by internal combustion engines, characteristics evocative by long association with high horsepower. To continue glorifying this outmoded technology means that well-known racing organizations have abandoned any meaningful proving ground aspect of their sport for the sake of pleasing the crowd with loud noise, fumes, and ludicrously low miles per gallon of fuel efficiency. Never mind tomorrow, they’re living for today, come what may.

Newer racing organizations are stepping forward with their own electric car circuits. As drivers test and prove the newer technology on the race track, manufacturers should be able to improve efficiency of the batteries and perhaps drop the price of consumer models to be on a par with, or even cheaper than, comparably equipped gasoline powered cars. When that happens, electric cars will start to overtake the old technology, the same way they were overtaken in their earliest form by the internal combustion engine in the early twentieth century.

The crucial piece of the puzzle needed to solve pollution problems comes from the power generating source, not the cars. That may happen on a more individual level than on a corporate or government level, as people will find it convenient to do most of their car charging at home, where they can be assured of a cleaner source by installing their own solar panels or wind turbines. Waiting for government to promote the necessary infrastructure changes to ensure cleaner power generation will not push improvements in transportation, decrease pollution, and ultimately limit the effects of global warming, not with the government currently in power.

Sowing Doubt for Fun and Profit

 

The first frost of fall was late this year across much of the U.S., in some places by one to three weeks, depending on the source of average frost date information. People who spend a lot of time outdoors tend to notice this, and also that a trend has developed of fall frosts arriving later and the last frost of spring coming earlier. Even people who pay attention to climate only sporadically may have noted the muted fall colors of the trees this year in parts of the eastern U.S., a result of extended warm weather and drought.

The growing season has increased over the last forty years or so, but that is not necessarily a good thing considering that short-lived creatures, such as insects, adapt more readily to swift changes than longer-lived plants and vertebrate creatures. Forty years is swift in the long view of climate. The short view is called weather, or weather events. Adding up weather events over forty years plots a trend in the climate. Unfortunately for the sake of rational discussion, too many people fail to make the distinction between weather and climate.

 

Not everyone agrees that the climate is getting warmer, or that if it is then humans are the cause of it. Some of those climate change deniers are motivated by their religious beliefs, others by a suspicion of government regulators, and still others are unmoved by the weight of scientific evidence, citing doubt about the conclusions. Who has sown that doubt? As always, we are well advised to follow the money. It comes as no surprise then that Big Oil, following the example set by Big Tobacco with regard to the link between burning their products and cancer, has worked to sow doubt about how the burning of fossil fuels contributes greenhouse gases to the atmosphere and causes a warming climate. Where there is doubt, they know, effective action against them can be hamstrung, and profits will continue to roll in until we all burn up from second hand smoke on a global scale.

Again following the money, the insurance industry is coming around to the reality of global warming and the increase in expensive weather events it is causing. The insurance industry, conservative gamblers that they are, are most interested in the economic facts they can pin down so as to minimize risk and maximize profit. They are not swayed by emotional appeals to religious or political views, but only by appeals to their bottom line. Another group whose costs are affected by the results of global warming are states and municipalities. As seas rise and severe weather events increase, causing unprecedented flooding, these entities have to pay for infrastructure improvements and higher insurance premiums.

 

States’ attorneys general are beginning to go after the fossil fuel industry to recoup costs, much as they did to the tobacco industry in the 1990s. It will be an even more protracted fight in this case because of the gargantuan amounts of money the fossil fuel giants can bring to bear; not everyone smoked in years past, after all, but today practically everyone uses gas, electricity, natural gas, plastics, and the list of products goes on. Some of these products can be replaced by use of renewable resources like wind and solar, but ultimately, like the reduction in use of tobacco products due to increasing social opprobrium, the steps for overcoming reliance on fossil fuel products and thereby breaking the economic stranglehold of Big Oil need to be taken by consumers, and that will require some wholesale changes in lifestyle, especially in the industrialized nations.
