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.

We Are Controlling Transmission

 


“It seems odd that every day we hear about a new smartphone app that lets you do something innovative, yet these modern-day mobile miracles don’t enable a key function offered by a 1982 Sony Walkman.”
― Ajit Pai, the new chairman of the Federal Communications Commission, in a speech he gave at a North American Broadcaster’s Association symposium on February 16, 2017.

 


If you have a smartphone, you might not be aware it has a chip in it that allows it to receive FM radio broadcasts. The phone manufacturers include the chip as a matter of course for all phones worldwide, and then coordinate with the carriers about activating it or not. In the United States, only about 44% of smartphones have activated FM radio chips, according to Mr. Pai. There are smartphone applications available that take advantage of the FM radio chip in the phone, and downloading and trying to use one of those applications is a way of determining if your carrier has activated the chip. Most likely, though, if you don’t see an application for “FM radio” already installed on the phone, then the chip is not activated.

Since the chip is already in the phone, why would the carriers not want it activated for their customers? Activation costs them nothing, after all. The carriers are suspiciously silent on this issue, which allows the rest of us, their paying customers, to speculate on their motivations and judge them harshly. Cellular phone companies are in the business of selling internet access along with phone service. Even though their phone contains a chip capable of receiving FM radio, most smartphone users can only access FM radio stations through an application such as TuneIn, which uses the internet to tap into a station’s streaming service, if it offers one. That sells data for the carriers. If your phone could access FM radio directly, your carrier would get nothing.


“We are controlling transmission.”


Besides saving data when accessing FM radio without using the internet, smartphone owners can expect longer battery life because their phone is not constantly using its transmitter to talk to the nearest cell tower the way it does when streaming media. The screen and the transmitter of a smartphone are the two biggest battery drains. Ownership of the phone brings up another issue – if it’s your phone, and it has the capability of receiving FM radio, your carrier should not be able to prevent you from using that feature. It appears the motivations of the carriers come down to greed and arrogance. Shocking!

To be fair, not all carriers disallow FM radio service and some of them disallow it only on some of their phones. No one understands why, because the carriers, who are in the communications business, are not talking. Some carriers don’t even bother to acknowledge there are public safety benefits to their customers of having access to FM radio outside of internet or cellular service during and immediately after a natural disaster, when those two services might be out of commission. The best course of action for smartphone users is to bring pressure to bear on their carriers, who up until now have been relying on the ignorance of their customers to get away with their policy. When you bought your phone, did your carrier advise you that it contained an FM radio chip? Most likely not, because then they would have had to explain why they wouldn’t let you use it. Take back control and make them explain themselves to you here and now.

Motorola Transistor Radio 1960
An early transistor pocket radio by Motorola. The first Motorola brand automobile radio was produced in 1930. Motorola began the commercial production of transistors at a new $1.5 million facility in Phoenix in 1955. This advertisement is from the May 23, 1960 issue of Life magazine (page 13). The 1960 price of $24.95 translates to a little over $200 in 2017.
