COMING: A BATTERY SUPPLY CRUNCH?
Several governments have signaled their intent to ban or greatly restrict the internal combustion engine from automotive use, requiring instead pure electrics or in some cases hybrids. These include China, France, and the United Kingdom, as well as the US state of California. Volvo says that from 2019 all its new models will be electric or hybrid, and General Motors is planning to introduce 20 electric models over the next six years.
The core of an electric vehicle is the battery, and these are large, heavy objects: the battery pack for a Tesla Model S comes in at 1300 pounds. Where are all the batteries for the envisaged exponential growth of electrics going to come from?…this question encompasses the mining and processing of the raw materials and the fabrication of these processed materials into battery cells, as well as the assembly of the cells into finished battery packs.
Will severe supply constraints for some of these materials put a practical limit on the growth of electric vehicles, even in the face of government subsidies and draconian edicts? Here’s a recent article in the Financial Times:
Volkswagen’s failed attempt to secure at least five years’ supply of cobalt highlights the challenge facing the world’s biggest automakers as they attempt to secure the materials needed for their push into electric vehicles. Last month’s tender came as other carmakers, such as BMW and Tesla Motors, are also trying to lock-in stocks of the metal. That could test to the breaking point a niche market that is heavily dependent on a handful of mines in the Democratic Republic of Congo, one of the most impoverished and politically volatile countries in Africa.
Demand for cobalt in EV batteries is expected to grow fourfold by 2020, and eleven-fold by 2025, according to Wood Mackenzie.
The graph accompanying the article indicates that the price of high-grade cobalt has risen from $15/pound in January of this year to $30/pound in October.

THE CUBAN MISSILE CRISIS, AS VIEWED FROM A SOVIET LAUNCH FACILITY (rerun)
This month marks the 55th anniversary of the Cuban Missile Crisis, which brought the world dangerously close to thermonuclear war.
Several years ago, I read Rockets and People, the totally fascinating memoir of Soviet rocket developer Boris Chertok, which I reviewed here.
Chertok’s career encompassed both military and space-exploration projects, and in late October 1962 he was focused on preparations for launching a Mars probe. On the morning of Oct 27, he was awakened by “a strange uneasiness.” After a quick breakfast, he headed for the missile assembly building, known as the MIK.
At the gatehouse, there was usually a lone soldier on duty who would give my pass a cursory glance. Now suddenly I saw a group of soldiers wielding sub-machine guns, and they thoroughly scrutinized my pass. Finally they admitted me to the facility grounds and there, to my surprise, I again saw sub-machine-gun-wielding soldiers who had climbed up the fire escape to the roof of the MIK. Other groups of soldiers in full combat gear, even wearing gas masks, were running about the periphery of the secure area. When I stopped in at the MIK, I immediately saw that the “duty” R-7A combat missile, which had always been covered and standing up against the wall, which we had always ignored, was uncovered.
Chertok was greeted by his friend Colonel Kirillov, who was in charge of this launch facility. Kirollov did not greet Chertok with his usual genial smile, but with a “somber, melancholy expression.”
Without releasing my hand that I’d extended for our handshake, he quietly said: “Boris Yevseyevich, I have something of urgent importance I must tell you”…We went into his office on the second floor. Here, visibly upset, Kirillov told me: “Last night I was summoned to headquarters to see the chief of the [Tyura-Tam] firing range. The chiefs of the directorates and commanders of the troop units were gathered there. We were told that the firing range must be brought into a state of battle readiness immediately. Due to the events in Cuba, air attacks, bombardment, and even U.S. airborne assaults are possible. All Air Defense Troops assets have already been put into combat readiness. Flights of our transport airplanes are forbidden. All facilities and launch sites have been put under heightened security. Highway transport is drastically restricted. But most important—I received the order to open an envelope that has been stored in a special safe and to act in accordance with its contents. According to the order, I must immediately prepare the duty combat missile at the engineering facility and mate the warhead located in a special depot, roll the missile out to the launch site, position it, test it, fuel it, aim it, and wait for a special launch command. All of this has already been executed at Site No. 31. I have also given all the necessary commands here at Site No. 2. Therefore, the crews have been removed from the Mars shot and shifted over to preparation of the combat missile. The nosecone and warhead will be delivered here in 2 hours.

CULTURE, INNOVATION, VICTORY, AND DEFEAT
(Today being Trafalgar Day, it seems like a good time to rerun this post)
In 1797, a Spanish naval official named Don Domingo Perez de Grandallana, wrote a thoughtful document on the general subject “why do we keep losing to the British, and what can we do about it?” His thoughts were inspired by his observations while with the Spanish fleet off Cape St Vincent, in a battle which was a significant defeat for Spain, and are relevant to a question which is very relevant to us today:
What attributes of an organization make it possible for that organization to accomplish its mission in an environment of uncertainty, rapid change, and high stress?
Here are de Grandallana’s key points:
An Englishman enters a naval action with the firm conviction that his duty is to hurt his enemies and help his friends and allies without looking out for directions in the midst of the fight; and while he thus clears his mind of all subsidiary distractions, he rests in confidence on the certainty that his comrades, actuated by the same principles as himself, will be bound by the sacred and priceless principle of mutual support.
Accordingly, both he and his fellows fix their minds on acting with zeal and judgement upon the spur of the moment, and with the certainty that they will not be deserted. Experience shows, on the contrary, that a Frenchman or a Spaniard, working under a system which leans to formality and strict order being maintained in battle, has no feeling for mutual support, and goes into battle with hesitation, preoccupied with the anxiety of seeing or hearing the commander-in-chief’s signals for such and such manoeures…
Thus they can never make up their minds to seize any favourable opportunity that may present itself. They are fettered by the strict rule to keep station which is enforced upon then in both navies, and the usual result is that in one place ten of their ships may be firing on four, while in another four of their comrades may be receiving the fire of ten of the enemy. Worst of all they are denied the confidence inspired by mutual support, which is as surely maintained by the English as it is neglected by us, who will not learn from them.
The quote is from Seize the Fire, by Adam Nicholson.

SPUTNIK ANNIVERSARY RERUN: BOOK REVIEW - ROCKETS AND PEOPLE
Today being the 60th anniversary of the Sputnik launch, here’s a rerun of a post about a very interesting book.
Rockets and People, by Boris E Chertok
Boris Chertok’s career in the Russian aerospace industry spanned many decades, encompassing both space exploration and military missile programs. His four-volume memoir is an unusual document–partly, it reads like a high school annual or inside company history edited by someone who wants to be sure no one feels left out and that all the events and tragedies and inside jokes are appropriately recorded. Partly, it is a technological history of rocket development, and partly, it is a study in the practicalities of managing large programs in environments of technical uncertainty and extreme time pressure. Readers should include those interested in: management theory and practice, Russian/Soviet history, life under totalitarianism, the Cold War period, and missile/space technology. Because of the great length of these memoirs, those who read the whole thing will probably be those who are interested in all (or at least most) of the above subject areas. I found the series quite readable; overly-detailed in many places, but always interesting. In his review American astronaut Thomas Stafford said “The Russians are great storytellers, and many of the tales about their space program are riveting. But Boris Chertok is one of the greatest storytellers of them all.” In this series, Chertok really does suck you into his world.
Chertok was born in Lodz, Poland, in 1912: his mother had been forced to flee Russia because of her revolutionary (Menshevik) sympathies. The family returned to Russia on the outbreak of the First World War, and some of Chertok’s earliest memories were of the streets filled with red-flag-waving demonstrators in 1917. He grew up on the Moscow River, in what was then a quasi-rural area, and had a pretty good childhood–“we, of course, played “Reds and Whites,” rather than “Cowboys and Indians””–swimming and rowing in the river and developing an early interest in radio and aviation–both an airfield and a wireless station were located nearby. He also enjoyed reading–“The Adventures of Tom Sawyer and Huckleberry Finn met with the greatest success, while Harriet Beecher Stowe’s Uncle Tom’s Cabin gave rise to aggressive moods–‘Hey–after the revolution in Europe, we’ll deal with the American slaveholders!” His cousin introduced him to science fiction, and he was especially fond of Aelita (book and silent film), featuring the eponymous Martian beauty.
Chertok remembers his school years fondly–there were field trips to study art history and architectural styles, plus a military program with firing of both rifles and machine guns–but notes “We studied neither Russian nor world history….Instead we had two years of social science, during which we studied the history of Communist ideas…Our clever social sciences teacher conducted lessons so that, along with the history of the French Revolution and the Paris Commune, we became familiar with the history of the European peoples from Ancient Rome to World War I, and while studying the Decembrist movement and 1905 Revolution in detail we were forced to investigate the history of Russia.” Chertok purused his growing interest in electronics, developing a new radio-receiver circuit which earned him a journal publication and an inventor’s certificate. There was also time for skating and dating–“In those strict, puritanical times it was considered inappropriate for a young man of fourteen or fifteen to walk arm in arm with a young woman. But while skating, you could put your arm around a girl’s waist, whirl around with her on the ice to the point of utter exhaustion, and then accompany her home without the least fear of reproach.”
Chertok wanted to attend university, but “entrance exams were not the only barrier to admission.” There was a quota system, based on social class, and “according to the ‘social lineage’ chart, I was the son of a white collar worker and had virtually no hope of being accepted the first time around.” He applied anyhow, hoping that his journal publication and inventor’s certificate in electronics would get him in.” It didn’t–he was told, “Work about three years and come back. We’ll accept you as a worker, but not as the son of a white-collar worker.”
So Chertok took a job as electrician in a brick factory…not much fun, but he was soon able to transfer to an aircraft factory across the river. He made such a good impression that he was asked to take a Komsomol leadership position, which gave him an opportunity to learn a great deal about manufacturing. The plant environment was a combination of genuinely enlightened management–worker involvement in process improvement, financial decentralization–colliding with rigid policies and political interference. There were problems with absenteeism caused by new workers straight off the farm; these led to a government edict: anyone late to work by 20 minutes or more was to be fired, and very likely prosecuted. There was a young worker named Igor who had real inventive talent; he proposed an improved linkage for engine and propeller control systems, which worked out well. But when Igor overslept (the morning after he got married), no exception could be made. He was fired, and “we lost a man who really had a divine spark.” Zero tolerance!
Chertok himself wound up in trouble when he was denounced to the Party for having concealed the truth about his parents–that his father was a bookkeeper in a private enterprise and his mother was a Menshevik. He was expelled from the Komsomol and demoted to a lower-level position. Later in his career, he would also wind up in difficulties because of his Jewish heritage.
The memoir includes dozens of memorable characters, including:
*Lidiya Petrovna Kozlovskaya, a bandit queen turned factory supervisor who became Chertok’s superior after his first demotion.
*Yakov Alksnis, commander of the Red Air Force–a strong leader who foresaw the danger of a surprise attack wiping out the planes on the ground. He was not to survive the Stalin era.
*Olga Mitkevich, sent by the regime to become “Central Committee Party organizer” at the factory where Chertok was working…did not make a good first impression (“had the aura of a strict school matron–the terror of girls’ preparatory schools”)..but actually proved to be very helpful to getting work done and later became director of what was then the largest aircraft factory in Europe, which job she performed well. She apparently had too much integrity for the times, and her letters to Stalin on behalf of people unjustly accused resulted in her own arrest and execution.
*Frau Groettrup, wife of a German rocket scientist, one of the many the Russians took in custody after occupying their sector of Germany. Her demands on the victors were rather unbelievable, what’s more unbelievable is that the Russians actually yielded to most of them.
*Dmitry Ustinov, a rising star in the Soviet hierarchy–according to Chertok an excellent and visionary executive who had much to do with Soviet successes in missiles and space. (Much later, he would become Defense Minister, in which role he was a strong proponent of the Soviet invasion of Afghanistan.)
*Valeriya Golubtsova, wife of the powerful Politburo member Georgiy Malenkov, who was Stalin’s immediate successor. Chertok knew her from school–she was an engineer who became an important government executive–and the connection turned out to be very useful. Chertok respected her professional skills, liked her very much, and devotes several pages to her.
*Yuri Gagarin, first man to fly in space, and Valentina Tereshkova, the first woman.
*Overshadowing all the other characters is Sergei Korolev, now considered to be the father of the Soviet space program although anonymous during his lifetime. Korolev spent 6 years in labor camps, having been arrested when his early rocket experiments didn’t pan out; he was released in 1944. A good leader, in Chertok’s view, though with a bad temper and given to making threats that he never actually carried out. His imprisonment must have left deep scars–writing about a field trip to a submarine to observe the firing of a ballistic missile, Chertok says that the celebration dinner with the sub’s officers was the only time he ever saw Korolev really happy.
Chertok’s memoir encompasses the pre-WWII development of the Soviet aircraft industry…early experiments with a rocket-powered interceptor…the evacuation of factories from the Moscow area in the face of the German invasion…a post-war mission to Germany to acquire as much German rocket technology as possible…the development of a Soviet ballistic missile capability…Sputnik…reconnaissance and communications satellites…the Cuban missile crisis…and the race to the moon.
Some vignettes, themes, and excerpts I thought were particularly interesting:
