Tesla Will Manufacture Model 3 Parts at the Gigafactory

As reported by Engadget: Nevada governor Brian Sandoval has announced that Tesla will bring some of its manufacturing for the Model 3 across from California. At a speech outlining policy initiatives for the last two years of his term, Sandoval revealed that the car company will build electric motors and gearboxes in the state.

The new lines will be installed at the Gigafactory, Tesla's 4.9 million square foot battery plant that it's building along with Panasonic. According to Fortune, the deal will create 550 new jobs at the facility, based in the city of North Las Vegas.


The news goes some way to answering the question as to how Tesla will build more than 400,000 of its new Model 3 cars in a reasonable time frame. Demand for the affordable EV vastly exceeded Elon Musk's wildest dreams, sending the company into something of a spin.

By moving the bulk of the drivetrain construction to the Gigafactory, Tesla's main Fremont facility in California will have more space to construct the rest of the vehicle. But even then, there are still issues for a business that has yet to ship a quarter of the Model 3's expected demand in a single year.

In 2016, Tesla managed to deliver 83,992 of its cars to customers, its most successful year as a car company. By 2018, it'll need to produce at least twice that figure on an annual basis or risk angering pre-order customers.

In order to cope, Tesla is raising a war chest apparently worth upwards of $2 billion and has recently purchased an automation company. No to mention that you'd be quite foolish to bet against Elon Musk when he's got all those rockets on standby.

Tesla's Autopilot Update Rolls Out

Tesla's Enhanced Autopilot update has rolled out to all its HW2 vehicles, company chief Elon Musk has announced on Twitter. HW2 is what the automaker calls its second-generation self-driving hardware found in its newer models, including the Model S and X. 

The Enhanced Autopilot update was designed to bring several autonomous features to the new hardware, such as autosteer, smart summon, autopark and auto lane change. Some of those features were available on the first-gen hardware, but Tesla had to deactivate them for HW2 until they've undergone more testing. Unfortunately, it might still take some time before you can try the reactivated features unless you're one of the 1,000 testers who had early access to them.

Musk said Enhanced Autopilot is in "non-actuating mode," which means it'll lurk in your system in an inactive state while Tesla continues to assess its reliability. If all goes well, the automaker could activate all the features that came with the update as soon as the end of this week. You'll know for sure once they've appeared on the system's patch notes.

SpaceX Falcon 9: Company Has Busy Launch Schedule

As reported by International Business Times: SpaceX is back in business. After being grounded from flight operations, following the spectacular Sept. 1 explosion of a Falcon 9 rocket while it was being refueled at its launch pad in Cape Canaveral, Florida, the Elon Musk company made its much-anticipated comeback Jan. 14.

Falcon 9’s resumption to flight was a keenly watched affair, since SpaceX reuses the first stage of the rocket, which brings down its launch costs, making it more affordable for companies who want to use its services. During Saturday’s launch, its first since the accident over four months ago, the rocket put a constellation of 10 Iridium NEXT communication satellites in orbit, and its first stage also landed successfully on a drone ship, called “Just Read the Instructions,” in the Pacific Ocean, off the coast of California.

The company had initially planned to return to flight in December 2016, but was forced to delay its plans, pending completion of its investigation into the Sept. 1 accident, and the acceptance of its report by both NASA and the Federal Aviation Administration. The delay also cost SpaceX some business when Inmarsat shifted the launch contract for its EAN satellite launch to Arianespace.
But now, with an estimated $10 billion worth of launch orders, it looks like Falcon 9 is going to be a busy rocket. Apart from the over 60 more satellites (in six batches) SpaceX is supposed to launch for Iridium in the coming months, the company has to make up for the over four months of delay.
According to the launch schedule posted on Spaceflight Now, a Falcon 9 rocket will make its next flight Jan. 26 from Florida, carrying an EchoStar 23 communications satellite into orbit, which will be used to broadcast digital television over Brazil. The next launch will be of SpaceX’s own Dragon spacecraft, which will leave Feb. 8 on a resupply mission for NASA to the International Space Station.
Later in February, the Falcon 9 rocket will likely make four more flights, including one to launch the next batch of 10 Iridium NEXT satellites. Another launch from California will carry Formosat 5, which belongs to Taiwan’s National Space Organization, as well as the Sherpa deployer — which will carry about 90 CubeSats and small payloads for a variety of commercial and scientific purposes — owned by Spaceflight Industries.
An SES 10 communications satellite, owned by Luxembourg-based SES, and a Koreasat 5A communications satellite, operated by South Korea’s KTsat, round out February for SpaceX launches. Both these satellites will launch from Florida; the former will provide television broadcast and telecommunication services over Central and South America, the Caribbean and Mexico, while the latter will provide similar services over South Korea, Japan and parts of South Asia.

Europe’s New Satellite System Will Improve Your Phone's GPS

As reported by MIT Technology ReviewGalileo, a global navigation satellite system that will reach more places and work more precisely than today’s GPS services, is now available for free public use. When it is complete, expected by 2020, Galileo will have taken two decades and an estimated $10 billion to build. But the system, created by the European Union, will make your phone run better and offer new possibilities for both corporate and government users.
With Galileo’s opening, announced this month, providers of a variety of services and devices, from specialized navigation systems to mobile-phone and car makers, will be able to add its signal to that of the 70-odd satellites in the American GPS and Russian GLONASS systems. At least 17 companies are already poised to do so, among them phone makers Huawei and BQ.
The more satellite signals available, the choosier your receiver can be. If buildings or other devices interfere with signals in one direction, your receiver may be able to find a less noisy signal from a satellite elsewhere. This means the Galileo satellites will make it easier to get a signal in places covered by fewer satellites, such as the far north of Europe, and provide more accurate and faster position fixes elsewhere, says Richard Langley, a geospatial expert at the University of New Brunswick in Canada and a member of a working group focused on research uses for Galileo’s data. Just one additional satellite “can make a huge difference” in position accuracy, he says.
When your phone finds less noisy signals, it frees the device’s processor for other tasks, explains Lukasz Bonenberg of the University of Nottingham in the United Kingdom, which is helping to build Galileo. That will allow developers, such as those who attended a Galileo hackathon last month, to design software that focuses on using location data rather than helping to interpret it, he says.
Galileo should also speed up search-and-rescue operations. Today it can take hours for a distress signal to reach enough low-orbiting satellites to confirm a position. Navigation satellites, which orbit higher, are more suitable for the task, but only the newest GPS and GLONASS satellites have the right hardware. All the Galileo satellites have it, and they should be able to locate rescue beacons in 10 minutes. An encrypted channel will be available to government agencies for emergency services.
Today the Galileo constellation consists of 18 satellites. Six more, enough for full global coverage of Earth, will be launched over the next three years by the system’s operator, the European Space Agency. (There will be six backup satellites as well, Galileo having learned a lesson from GPS and GLONASS’s struggles with dud satellites.)
Galileo is one of a growing number of satellite navigation systems. China is building its own, BeiDou, also scheduled for completion in 2020. Other countries, including India and Japan, have growing regional navigation systems as well.
These systems are interoperable, and researchers around the world are  developing efficient algorithms for combining signals from multiple constellations. As more of these satellites come online, location information will get even better.

A French Town Just Installed the World's First 'Solar Road'


The tiny town of Tourouvre-au-Perche in Normandy, France no longer has to worry about how it will power its street lights. The Sun will handle that.

French Ecology Minister Ségolène Royal (below) officially opened the kilometer-long road on Wednesday. It took five years to develop and cost $5.2 million to produce and install the 30,000 square feet of solar panels. They're coated with a clear silicon resin that enables them to withstand the impact of passing traffic.

Being the first of its kind, the panels are still prohibitively expensive to produce en masse (they're also less efficient than conventional panels because they're laid flat rather than angled). But should Colas, the road's manufacturer, figure out how to get costs down and efficiency up, France may install them along another 1,000 kilometers of its roads.

US DOT Unveils 'V2V' Rule Requiring Cars to ‘Talk’ to Each Other

As reported by The HillOn Tuesday, the US Department of Transportation (DOT) proposed a rule to "advance the deployment of connected vehicle technologies in 'light-duty" vehicles." The rule would mandate that all new cars implement vehicle-to-vehicle (V2V) technology—and, according to US DOT secretary of transportation, Anthony R. Foxx, this could happen in 100% of new cars in roughly five years.

"Today's announcement is the next step in our march toward capturing safety opportunities in new technologies," Foxx said at a press conference. "We recognize the potential technology to improve safety and improve the relationship between everyday Americans and transportation."
"There's a single number that motivates everything we do: 35,092. That number is how many American died on roadways last year," said NHTSA Administrator Mark Rosekind. According to Rosekind, V2V infrastructure has the potential to prevent up to 80% of "non-impaired crashes."
"That potential is something we have to do everything we can to realized," he said.
To prevent crashes, V2V tech will employ features like advanced warning systems, automated crash avoidance, and adaptive cruise control. The proposed implementation of V2V technology, Foxx said, will also "provide 360-degree situational awareness on the road and will help us enhance vehicle safety." While "folks can turn off the warning," Foxx said, "the broadcast cannot be turned off."
The announcement follows on the heels of the US DOT's policy for autonomous vehicles—the first-of-its kind guidelines for the development of autonomous vehicle technology in September 2016. According to Rosekind, V2V and automation technology are "highly complementary." Also, Rosekind said that vehicle-to-infrastructure (V2I) technology is important piece of the proposal, and the agency "plans to soon issue guidance for V2I communications, which will help transportation planners integrate the technologies to allow vehicles to 'talk' to roadway infrastructure such as traffic lights, stop signs and work zones to improve mobility, reduce congestion and improve safety."
The proposal "has the potential to save lives, but it is certain to add costs to vehicles," said Michael Ramsey, autonomous vehicle analyst at Gartner. "In addition, with the increasing number of sensors on vehicles, from cameras and radar to eventually Lidar, V2V may become a redundant technology. Companies like Delphi stand to win big from this announcement. Already it is supplying this technology to GM to be launched in a Cadillac in 2017."
Also, there are unanswered questions: How will a new administration affect the development of these regulations? How can cybersecurity issues be safely addressed? The DOT said its V2V system will not collect or share personal information and that it is "a safety tool, not a data-gathering tool." Still, cybersecurity concerns should remain a priority in safely implementing the technology.
"I'm glad this proposed rule has finally been released," said Bryant Walker Smith, leading legal expert in autonomous vehicles. "I'm concerned how it—and also spectrum allocation—will fare in the next administration."
Still, the move is a big step forward for recognizing the power of vehicle technology to increase safety on the roads. Smith said that, when integrated, the guidelines "provide a whole new infrastructure upon which innovations we have yet to conceive could occur."
The proposed rulemaking will be open for public comment for 90 days, according to the DOT.

GPS Location Data for Four Million Commutes Reveal New U.S. 'Megaregions'

As economic centers grow in size and importance, determining their boundaries has become more crucial.


An ever increasing share of the world’s population is living in what are known as megaregions—clusters of interconnected cities. The concept of the megaregion is decades old and fairly easy to grasp, but geographically defining them has turned out to be rather tricky.


Now, researchers have attempted to map the megaregions of the contiguous United States by studying the commutes of American workers.


As megaregions grow in size and importance, economists, lawmakers, and urban planners need to work on coordinating policy at this new scale. But when it comes to defining the extent of a megaregion, they find themselves running into the same problems geographers and cartographers have always had when trying to delineate conceptual areas. Because megaregions are defined by connections—things like interlocking economies, transportation links, shared topography, or a common culture—it’s tough to know where their boundaries lie.


To try to solve this geographical problem, Garrett Nelson of Dartmouth College and Alasdair Rae of the University of Sheffield used census data on more than four million commuter paths and applied two different analyses, one based on a visual interpretation and the other rooted in an algorithm developed at MIT. Their results and maps appear today in the open-access journal PLOS ONE.


The map (left side) shows all the commutes of 50 miles or less (represented by straight lines between the start and end points) surrounding the San Francisco Bay Area, one of the more iconic megaregions in the country. Shorter, higher volume commutes are in yellow, with longer, lower volume paths in red. In this image it’s easy to see that the main centers of work are in cities, including San Francisco, Oakland, San Jose, and Sacramento, and that they are highly connected. (See "A Commuter Revolution: How Cities Are Collaborating to Solve the Challenges of Sustainable Urban Transport")


But where should planners draw the edges of a megaregion encompassing this activity? Which connections are statistically significant? Which are important for regional transit planning? Should they focus on the cities surrounding the bay, or is Sacramento just as important to the Bay Area economy?


For answers to these questions, Nelson and Rae turned to an algorithm-based tool designed by MIT’s Senseable City Lab to mathematically recognize communities. The algorithm only considers the strength of connections between nodes (more than 70,000 census tracts in this case), ignoring physical locations. This made for a nice test of Waldo Tobler’s “first law of geography”: that things that are near each other are more related than those that are farther apart.


The results of the algorithmic analysis took some cleanup and iterations—such as eliminating superlong commutes between places like New York City and Los Angeles and excluding nodes with only very weak connections—to produce a coherent map of plausible megaregions. The difference between the visual and mathematical approaches can be seen in the map above of the Minneapolis-St. Paul area.


 In the visual analysis on the left, activity clearly centers on the twin cities and extends outward concentrically, with weaker connections to surrounding cities. But where does the twin-cities megaregion end? Should St. Cloud be included? What about Rochester? In the smaller-scale map on the right, the algorithm assigned a broad swath of smaller surrounding cities, including Fargo, North Dakota, to the megaregion based on commuting paths. Here, the twin cities area shows up as the largest of multiple centers of activity. (See "The City Solution: Why Cities Are the Best Cure for Our Planet’s Growing Pains")


One of the decisions the researchers made was to limit the algorithm to 50 megaregions, which can be seen in the map below, where every node is colored according to the region it belongs to. This made the map more plausible visually. While 50 may sound like an arbitrary number, it makes sense mathematically because a very high percentage of commutes lie entirely within a megaregion relative to paths that cross boundaries between regions.

These algorithmic megaregions are easier to interpret on the map at the top of the post, which shows the connections. There are a few seemingly odd results, such as the sharp boundary that follows the New York-Connecticut state line or the small, splotchy green megaregion that floats between Birmingham and Dallas. Clearly, by ignoring geographical information and having no understanding of the country’s cultural character, the statistical method didn’t get everything right.


So Nelson and Rae combined the two methods to draw final boundaries around the country’s megaregions. They started by drawing lines around the dots on the map above. They then overlaid those shapes on the flow map at the top of the post and reinterpreted the boundaries to eliminate outliers and emphasize geographic continuity. The result is the map below, which eliminates some visual oddities. For example, the splotchy green area has been absorbed by the New Orleans-Delta megaregion, and a big swath of the west with relatively low population isn’t included in any megaregion.


The researchers hope their approach is a first step to a better grasp of the economic geography of the country. The map is clearly a work in progress, and some areas still don’t look right—the division of the New York City tri-state area into two megaregions, for example. And I’m not convinced the Bay Area-Sacramento megaregion where I live should extend all the way to Nevada. Does the map assign your home and workplace to a megaregion that makes sense to you?
