Elon Musk recently made the cover ofFortune (Dec.9, 2013) as its 2013 Business Person of the Year for his famous creation of both Tesla and Space X.  The article recalls that just a few years back, the best most people could say about electric cars was that they would be great for sustainability, but for the foreseeable future they’d be horribly limited by range and wouldn’t be very appealing to drive. Battery technology was simply too expensive and too heavy for it to be otherwise. The key breakthrough was to switch to lithium-ion battery technology, an expensive technology used not in cars, but in computers and phones.  Musk believed that if you could combine large enough numbers of lithium-ion cells into a single battery, you could provide not only adequate range for a car but also power capable of turning the humble electric car into an object of desire.

Musk wasn’t the first person to have that insight. His genius was to take that core idea to its logical conclusion and integrate it into a broader picture of how a series of such cars could be manufactured and marketed for ever-shrinking costs, in a sequence that would eventually bring Tesla to the mass market. A full seven years ago, he posted an article titled “The Secret Tesla Motors Master Plan,” which outlined the basics: three generations of cars, first the super high-end sports car, then a sporty 4-door family car, then a mass market car. And underpinning it all, the conviction that the cars wouldn’t just work, but be lusted after.

He had no certainty that the company would succeed. But he was convinced that (a) the laws of physics meant that electric power could deliver a profoundly better automobile, (b) there was a path to possible success via three generations of cars, and (c) the goal was essential if humanity was to have a shot at a sustainable-energy future. This  5 minute video of the Tesla S production is one your students will enjoy as it shows the power of robotics in manufacturing

IT BEGAN with a boom. In 1947, Chuck Yeager became the first man to break the sound barrier. He flew from Edwards Air Force Base in the Mojave Desert, America’s main center for experimental military flights. This base was out-of-the-way of prying eyes and surrounded by landscape into which a crash (and there were many) would not inconvenience anyone. Now, reports The Economist (Dec.21,2013-Jan. 4, 2014), the Mojave Desert is emerging as the site of a cluster of what has come to be known as New Space.

The center of activity is 20 miles from Edwards, around the Mohave civilian airfield, now dubbed the Mojave Air and Space Port (see photo). Today, 17 rocket and space-related companies operate in the Air and Space Port. Most hope to make their money from launching satellites. Two, though, plan to enter the trade of taking tourists into space.Scaled Composites has designed and built SpaceShipTwo, a rocket plane intended to carry paying passengers to 100km above Earth using a hybrid rocket engine. Competitor XCOR’svehicle, Lynx, plans to fly this year.  It, too, is a rocket plane, but is designed to take off from a runway under its own power.

Stratolaunch Systems proposes to take the air-launched-rocket principle and push it to the limit.  Orbital Sciences makes an air-launched rocket, Pegasus, which is used to put satellites into orbit, and the firm also has a contract to resupply the International Space Station. Firestar Technologies is developing a liquid fuel that requires only one tank and no complicated mixing mechanism in the motor, which simplifies engineering. Interorbital Systems is designing small, cheap rockets that can be strapped together in bundles, using as many as are necessary to lift a given payload into orbit.
