Driverless Flying Taxi Service set to Launch in Dubai

As reported by CNN: Dubai has announced yet another pioneering initiative, but this time it's not the world's first rotating skyscraper or 3D printed office. It's a fleet of flying taxis.
Small enough to fit into a car parking space when folded up, the one-seater passenger drones made by Chinese company Ehang are set to start picking up passengers in July this year, according to Dubai's Road and Transport Authority (RTA).
    The electrically powered driverless drones -- named Ehang 184 -- have already been seen hovering above the sand dunes near the city's airfield during test flights.
    "The 184 provides a viable solution to the many challenges the transportation industry faces in a safe and energy-efficient way," said Ehang founder and CEO Huazhi Hu when the vehicle was unveiled during the 2016 CES gadget show in Las Vegas.
    "The 184 is evocative of a future we've always dreamed of and is primed to alter the very fundamentals of the way we get around."

    Self-driving transport strategy

    While the exact details of the project's logistics are yet to be revealed, Dubai's RTA says the futuristic venture is part of a strategy to have self-driving vehicles (of all kinds) account for a quarter of journeys made in Dubai, by 2030.
    "This project supports Dubai's government's direction to become the smartest city in the world," HE Mattar Al Tayer, director general of RTA, said in an email to CNN.
    He adds that the drones, which he refers to as Autonomous Aerial Vehicles (AAV), are an easy-to-use innovation that can transport up to 100 kilograms -- enough for one person and a suitcase -- on a pre-programmed route through the city.
    "The passenger just needs to pick the destination through a smart screen [once inside the vehicle] and the AAV takes care of the rest."

    Monitored by ground control

    Powered by eight propellers, Ehang says the 184 (which stands for one person, eight propellers, four arms) will cruise at around 100 kilometers per hour.
    The routes will be programmed by a ground control center through an encrypted 4G network which will monitor the flight.
    Awesome as it might sound to sit back and take in the view as the rest of Dubai is stuck in traffic jams, there are some limitations to the technology.
    With a 30-minute maximum battery time, it won't take you very far.
    And then there are the usual concerns about drones in busy airspaces and the safety of driverless vehicles.
    But like it or not, automated passenger drones will become a reality, says Captain Ross Aimer, CEO of US-based Aero Consulting Experts..
    "It's the future," he told CNN. "We have the technology and it can be done. It's time."
    "The passenger drone is really just one step up from the delivery drones we've seen perforating the skies in recent years,"

    'What if?'

    A pilot himself, Aimer is watching the venture with great interest and has identified both pros and cons with the driverless technology.
    Among the caveats is the question of what happens if ground control loses the connection to the drone, he says.
    "That's most people's concern with any pilotless aircraft," says Aimer. "We have the technology to send a signal to that aircraft and control it and communicate with it, but what happens if that technology is interrupted for some reason?
    According to Ehang, in the event of any problems the drone will immediately land at the nearest safe spot. But that may not be enough to reassure everyone.
    As Aimer puts it -- "My question is: who's gonna be the man or woman crazy enough to be the first passenger?"

    SpaceX is Pushing Hard to Bring the Internet to Space

    As reported by The Verge: For months, SpaceX has been quietly meeting with the FCC to advocate for one of its least-known projects. According to recent disclosures, the company met with FCC officials twice in recent weeks: first with a wireless advisor on February 28th and again on March 10th with Chairman Pai himself. The same two topics came up at each meeting: the first was a stalled proposal to ease the regulatory demands on commercial space launches. The second was far more ambitious: SpaceX is seeking a license for a lucrative, globe-spanning satellite network that would bring terrestrial internet into space. Musk didn’t attend either meeting, but SpaceX president and COO Gwynne Shotwell was there in his place. (SpaceX declined to comment beyond its public filing.)
    Musk has been batting around the idea of a "space internet" for years, initially proposing it as a way to connect SpaceX’s Martian colonists. In the near-term, the system can be adapted to deliver easy, continuous access to base stations around Earth, providing simple connectivity to the planet’s most remote communities. A proposal filed in November shows how the system would actually work: 4,425 satellites in non-geostationary orbit traveling in a tightly choreographed ballet 700 miles above the surface of the Earth, keeping at least one satellite 40 degrees above the horizon at nearly every spot on Earth.
    A CONSTELLATION OF 4,425 SATELLITES
    Companies have long toyed with the idea of a satellite network that delivers data directly to individual devices or small base stations. In the ‘90s, Motorola backed a similar project called Iridium. But, torn between spiraling investment costs and waning consumer interest, the project went bankrupt just nine months after launch. After an estimated $6 billion in development costs, the firm was bought by investors for $35 million in 2000. Iridium’s main competitor, the Qualcomm-backed Globalstar, met a similar fate.
    But now the dream of a globe-spanning satellite network looks like an increasingly feasible reality — particularly with 5G technologies just a few years away, promising new devices and new demand for data. That’s attracting investment from a batch of satellite providers that includes SpaceX, its longtime rival Boeing, and a more recent challenger called OneWeb, all of whom have proposed similar constellations. And all three would employ similar portions of the wireless spectrum to complete their network.
    The business risk of building such a network is substantial. The constellations will cost at least 6 billion dollars, with costs growing as each project scales up. With the constellations at least five years away from operation, many observers think it’s unlikely all three companies will go the distance, with funding and regulatory support consolidating around the likely winner. If the resulting winner becomes an integral part of the cellular network, it’s easy to envision making that money back — but it’s just as easy to imagine the whole thing spiraling into bankruptcy before reaching the finish line.
    A VERY RISKY BET
    Then, there’s the question of the FCC, which controls the airwaves those satellites will need to reach US customers. OneWeb was the first to submit an application for that spectrum, filing in June of last year. The commission responded with a call for proposals from anyone who wants to use the relevant wavelengths for a satellite-connectivity project. That inspired similar filings from SpaceX and other competitors — and in the coming months, the commission is expected to rule on all of them. Given the FCC’s traditional enthusiasm for market competition, observers expect a permissive ruling, inviting all the companies to use the relevant spectrum, but asking them to work together and stay out of each other’s way. Even after the ruling, the FCC will continue to play a key regulatory role, setting deadlines and stepping in if talks between the companies break down. There’s no indication Chairman Pai wants to pick winners in this new space race, but if one of the contenders starts missing deadlines and causing interference, he may have no choice.
    Against that backdrop, SpaceX’s meeting with Pai takes on greater significance. Musk has drawn criticism for his ties to the Trump administration, and just two days before the Pai meeting, he was at Trump Tower, joining real estate developers and cabinet members for a discussion of the president’s infrastructure plans. Musk has defended the meetings as a way to push good policy — but as SpaceX prepares for one of the biggest projects in its history, having a few friends in the White House certainly couldn’t hurt.

    These Toaster-Oven-Size Radios Will Help Bring 5G to Life

    Within a few years, 5G networks could turbocharge your smartphone.  But can they pass the tests cooked up by
    engineers at an office park in New Jersey?
    As reported by MIT Technology Review: Live-streaming a virtual-reality broadcast. Downloading a 90-minute high-definition TV show to your smartphone in less than three seconds. Sending instant updates on road conditions to self-driving vehicles. These scenarios are impossible or prohibitively expensive on current cellular networks, but they should be feasible with the next generation of wireless connectivity, 5G. It promises to be 10 to 20 times faster than today’s cell-phone networks.

    That’s because 5G will operate in a high-frequency portion of the radio spectrum, known as millimeter wave. It has a lot of available bandwidth and should make it possible for wireless devices to process data with minimal delays. But since its wavelengths are much shorter, it is more easily obstructed. And because it has never been used for consumer mobile services, carriers are still learning how 5G signals will behave in different types of terrain and weather. “We need to look at how the signals are affected by things like snow, rain, sleet, hail, maple trees, oak trees, and spruce trees, because each of those will be different,” says AT&T research engineer Bob Bennett.

    The problem: most 5G measurement equipment is so expensive, fragile, and bulky that it can be deployed outdoors for only a few hours at a time. ­Bennett and colleagues say that far more real-world data is needed to properly develop the technology, so they have created weatherproof radios the size of toaster ovens and installed them across AT&T’s 260-acre campus in Middletown, New Jersey, which was once part of Bell Labs.

    Since deploying the radios last September, the engineers have seen how tree leaves, heavy rain, and truck traffic all obstruct millimeter-­wave signals to some extent. AT&T plans to share the information with the rest of the telecom industry to aid in the design of 5G technical specifications, base stations, modems, smartphone chips, and more. The new technology won’t be commercially widespread until after 2020, but these small, homemade radios are a crucial step toward making it real.

    The components are housed in weatherproof boxes that are small enough to fit on telephone poles.

    Th roof of the main building on the Middletown campus is home to five 5G measurement systems, as well as other radios, weather stations, and solar panels.

    Research engineers hacked together these testing devices as part of their effort to see how 5G networks will perform in wooded areas and inclement weather.

    Later this year, AT&T plans to install additional 5G measurement systems outdoors, and may use one of  it's testing vans to conduct tests outside the Middletown campus.  The van's mast can extend up to 50 feet.
    Cell towers like these let AT&T engineers simulate how 5G will behave in the real world.  Commercial deployment is expected to being in 2020, after companies around the world hammer out technical standards.

    Virginia is the First State to Pass a Law Allowing Ground Robots to Deliver Straight to your Door

    As reported by Recode: Virginia has made robotics history. The commonwealth is the first state to pass legislation allowing delivery robots to operate on sidewalks and crosswalks across the state.
    The new law goes into effect on July 1 and was signed into law by the governor last Friday.
    The two Virginia lawmakers who sponsored the bill, Ron Villanueva and Bill DeSteph, teamed up with Starship Technologies, an Estonian-based ground delivery robotics company, to draft the legislation.
    Robots operating under the new law won’t be able to exceed 10 miles per hour or weigh over 50 pounds, but they will be allowed to rove autonomously.
    The law doesn’t require robots to stay within line of sight of a person in control, but a person is required to at least remotely monitor the robot and take over if it goes awry. Robots are only allowed on streets in a crosswalk.
    Municipalities in the state are allowed to regulate how robots will operate locally, like if a city council wants to impose a stricter speed limit or keep them out entirely.
    “There wasn’t push back [from legislators],” Rep. Villanueva said in an interview with Recode. “It was more like intrigue and curiosity about the technology, what the application would be, how it would benefit the citizens.”
    Companies like Amazon and Grubhub sent Virginia lawmakers letters of support to pass the new robotic delivery law, said Rep. Villanueva.
    Though Starship Technologies helped to pass the new law, it also opens the doors to other ground delivery robotics companies to operate in Virginia, too. Companies like Marble and Dispatch are also working to bring robots for autonomous delivery to city sidewalks.
    Starship is already testing its robots with Postmates in Washington, D.C., and DoorDash in Redwood City, Calif.
    Legislation similar to what passed in Virginia has been proposed in both Idaho and Florida.

    SpaceX Plans to Send Two People Around the Moon

    As reported by The Verge: SpaceX has plans to send two private citizens around the Moon, CEO Elon Musk announced today.
    It will be a private mission with two paying customers, not NASA astronauts, who approached the company. The passengers are “very serious” about the trip and have already paid a “significant deposit,” according to Musk. The trip around the Moon would take approximately one week: it would skim the surface of the Moon, go further out into deep space, and loop back to Earth — approximately 300,000 to 400,000 miles.
    The plan is to do the trip in the second quarter of 2018 on the Crew Dragon spacecraft with the Falcon Heavy rocket, which is due to do its maiden launch this summer. Of course, Musk is well-known for his unrealistic deadlines — in 2011, he promised to put people in space in just three years.
    The two people going on the trip, who weren’t named, already know each other. They will begin initial training for the trip later this year. Musk declined to comment on the exact cost of the trip, but said it was “comparable” or a little more than the cost of a crewed mission to the International Space Station. For context, one ticket on the Russian Soyuz rocket costs NASA around $80 million.
    Musk believes these private missions could be a “significant driver of revenue” for the company and expects to have at least one or two a year, possibly making up 10 to 20 percent of SpaceX revenue.
    A permit from the United Nations will not be necessary, according to Musk, though the trip will need to be licensed by the Federal Aviation Administration.
    This announcement comes as NASA is thinking about a similar mission. The agency has considered putting astronauts on the first flight of its next big rocket, the Space Launch System (SLS). The plan was for NASA to fly the SLS for the first time, uncrewed, in the fall of next year. But a memo sent to NASA employees earlier this month showed that the agency was considering making the first flight of the SLS a crewed mission instead. That flight would take a crew around the Moon, echoing SpaceX's Moon mission plans.
    “It’s a particularly opportune moment to announce this as a new administration comes in and grapples with their plans for NASA,” Phil Larson, a former space advisor to President Obama and a former SpaceX representative, tells The Verge. “We’ve all seen the reports of the NASA team looking at opportunities with the Moon, and the announcement by NASA that they’re studying moving [Exploration Mission 2] up with Orion and SLS goes to show the new team is looking at new ways to do things in space. I don’t know if they’re looking for this kind of partnership or not but presents a new opportunity for them that a private company will do something like this.”
    Musk has made it clear that NASA would have priority in any lunar orbit mission. “If NASA decides to have a mission of this nature be a NASA mission, then of course NASA would take priority,” he says.
    The Crew Dragon, which hasn’t yet flown, is an automated vehicle; the system will operate autonomously for most of the flight. If there is an emergency, the passengers will need to probably step in, but “the success rate is quite high,” says Musk. There will be changes to the Dragon’s communication system, mostly to allow deep space communication.
    The company expects to fly an uncrewed Crew Dragon with Falcon 9 to ISS by the end of this year. There will be another mission six months later with a NASA crew. Six months after that, if all goes as planned, is when the two people would fly around the Moon. These paying customers “are entering this with their eyes open, knowing that there is some risk here,” says Musk. “We’re doing everything we can to minimize that risk but it’s not zero.”
    Spaceflight is inherently dangerous, and there are no government regulations in place specifically to keep people safe during commercial space travel. In 2004, Congress passed the Commercial Space Launch Amendments Act, which created a “learning period” without regulations for the private sector. Though it was set to expire in 2012, it has been extended through 2023. Up until now, though, the vast majority of commercial spacecraft have been uncrewed. The FAA is concerned about the spacecraft that will carry people, like this one, and the agency has expressed interest in regulating commercial spaceflight in the future.
    SpaceX has already been developing the Crew Dragon to carry people for NASA, as part of the agency's Commercial Crew Program. It's an initiative that tasks two private companies — SpaceX and Boeing — with developing vehicles that can carry people to and from the International Space Station.
    SpaceX's target date for the first official crewed mission is supposed to take place in 2018. But a recent report from the Government Accountability Office suggested that the company’s vehicles may not be certified until 2019. Musk has tweeted that, despite the report, SpaceX will be ready.
    It might pay to be skeptical, though. SpaceX initially promised to begin ferrying astronauts to the ISS by 2017 as part of NASA’s commercial crew program. That date is clearly no longer on the table. Also, in 2011, Musk told The Wall Street Journal that his best-case scenario was to put people on Mars by 2021 (his worst-case scenario was between 2026 and 2031). Last year, he said he was planning to put people on Mars as early as 2024. So the target of 2018 should perhaps be taken with a grain of salt.
    SpaceX expects to do more than one Moon mission. Other flight teams have already expressed interest in going on future trips.
    “Next year is going to be the big year for carrying people,” says Musk. “This should be a really exciting mission that hopefully gets the world really exciting about sending people into deep space again.”

    Elon Musk Is Really Boring...Tunnels

    As reported by Bloomberg News: The pit is at least 15 feet deep and more than 50 feet wide. It’s in a nondescript lot at Crenshaw Boulevard and West 120th Street, not far from Los Angeles International Airport. If not for the huge pile of dirt next to it, you’d never know it was there. Seen from the top of the parking garage at SpaceX, the aerospace startup founded by Elon Musk, the hole is an eyesore among eyesores—a crater in asphalt, fenced in by rusty-looking steel plates.

    But Musk, the chief executive of both SpaceX and the electric car company Tesla, is quite proud of this pit. He started digging as a spur-of-the-moment thing one weekend at the end of January. The idea came to him while sitting in a traffic jam early on a Saturday morning in December. “Traffic is driving me nuts,” he tweeted. “Am going to build a tunnel boring machine and just start digging.” Within an hour, the project had a name and a marketing platform. “It shall be called ‘The Boring Company,’ ” he wrote. “Boring, it’s what we do.” Two hours passed, and Musk tweeted again: “I am actually going to do this.”
    It sounded like a put-on. Musk is a serious person, but he can also be something of a loose cannon, making outlandish statements designed to troll the press or simply amuse himself. In a 2015 interview with Stephen Colbert he semi-seriously endorsed dropping nuclear weapons on Mars; last year he implied on Twitter that he’s developing an Iron Man-style flying suit for the Pentagon. Most reporters assumed that the tunnel thing was another one of his jokes.

    Musk wasn’t joking. At least that’s what he tells me as we sit in the SpaceX offices in Washington. For years he’s been thinking about tunnels—both out of a personal fascination and because they’d be an important component of the Hyperloop, the fanciful high-speed rail system he proposed in 2013. All the while he’s been quietly encouraging anyone who asks him about new business opportunities to consider digging for a living. “I think they were hoping I’d say some sort of iPhone app that they could make,” he says with a smile. “I would just say, ‘Do tunnels.’ It would obviously solve urban congestion—and we wouldn’t be stuck in soul-destroying traffic all the time.”

    As Musk tells it, the L.A. traffic jam was a breaking point. Screw it, he thought, I’ll do tunnels myself. Within days of his tweetstorm, he acquired a domain name—BoringCompany.com—and appointed a leader for the project, Steve Davis, a senior SpaceX engineer who designed the guidance systems for the company’s first rocket. The barely sketched plan was to dig lots of tunnels for cars and high-speed trains. Mostly, Musk was going to approach it in his usual way: He’d figure it out as he went along.

    One of the advantages of running two large industrial companies is that you can secure earth-moving equipment on short notice. And so, around noon on a Friday in January, an excavation crew started digging. “I was like, ‘Hey, what’s the biggest hole we can make by Sunday evening?’ ” Musk says.

    Shortly after the 2016 election, Steve Bannon, Donald Trump’s chief strategist, implied that the incoming administration would pursue infrastructure with a fervor not seen since the New Deal. “The conservatives are going to go crazy,” he toldthe Hollywood Reporter. “I’m the guy pushing a trillion-dollar infrastructure plan. With negative interest rates throughout the world, it’s the greatest opportunity to rebuild everything. Shipyards, ironworks, get them all jacked up. We’re just going to throw it up against the wall and see if it sticks.” On Inauguration Day, Trump promised “new roads and highways, and bridges, and airports, and tunnels, and railways all across our wonderful nation.”

    Like the Boring Company itself, Trump’s big-league construction agenda seems a little half-baked, but the possibility has already prompted private equity firms such as Blackstone and Carlyle to plan big infrastructure investments. “Infrastructure is at an inflection moment in the United States, where both parties agree on that one thing,” said Joe Baratta, Blackstone’s global head of private equity, during a Bloomberg TV interview in late January. He said his firm would raise as much as $40 billion for the efforts.

    Musk wouldn’t seem to be in a particularly good ideological position to benefit from Trump’s infrastructure largesse. He’s a climate change hawk who was so closely identified with the Obama administration that Mitt Romney attacked Tesla during the 2012 debates. (Tesla had received a government-guaranteed loan in 2010.) In the next presidential election, Musk supported Hillary Clinton for president, describing Trump, in an interview with CNBC, as a man who “doesn’t seem to have the sort of character that reflects well on the United States.”

    But after the election, Musk made several trips to Trump Tower, impressing the president and, especially, Bannon. A former Goldman Sachs banker, Bannon is the main proponent of Trump’s “America First” economic nationalism. After meeting privately with Musk on Jan. 6, Bannon told an associate that he views Musk and his companies as embodying the kind of U.S.-based job growth that Trump intends to foster. For Trump, who’s been publicly shunned by many Silicon Valley executives, the connection to Musk gives his administration a whiff of innovation and dynamism. In December, Musk was named to Trump’s Strategy and Policy Forum, an advisory group that includes IBM’s Ginni Rometty, Pepsi’s Indra Nooyi, and JPMorgan Chase’s Jamie Dimon.

    Musk has warmed to Trump, too. In January he offered his support for Trump’s chosen secretary of state, former ExxonMobil CEO Rex Tillerson, despite having frequently criticized oil companies in the past. “This may sound surprising coming from me,” Musk wrote on Twitter, but “Rex Tillerson has the potential to be an excellent Sec of State.” He noted that Tillerson has expressed openness to a carbon tax, a policy Musk has long supported. After Trump issued a temporary ban on immigration from seven Muslim-majority countries, Musk criticized the order but also urged his many left-leaning followers to read its full text before freaking out.

    Whereas Uber CEO Travis Kalanick left the Strategy and Policy Forum in response to protests, Musk is sticking with it. “Attending does not mean I agree with actions by the administration,” he wrote in a statement. “I believe at this time that engaging on critical issues will on balance serve the greater good.”

    Our conversation at SpaceX takes place a few hours after his Feb. 3 meeting with Trump. Musk is attired in his strategy-forum best—black suit, white shirt, blue tie—and seems sleep-deprived and loopy as he deflects my question about Trump and changes the subject to the Boring Company, launching into what I can best describe as a tunnel-themed comedy routine.

    “My other idea was to call it Tunnels R Us and to essentially troll Toys “R” Us into filing a lawsuit,” he says, letting out a loud and well-articulated ha-ha-ha-ha. “Now we’ve decided to troll AT&T instead! We’re going to call it American Tubes and Tunnels.”

    When I ask him if the tunnel venture will be a subsidiary of SpaceX or an independent company, he responds cryptically. “Don’t you read my Twitter? The Boring Company. Or TBC. To Be Continued.” An aide chimes in: Yes, the Boring Company, aka To Be Continued, aka Tunnels R Us, aka American Tubes and Tunnels, aka whatever, will indeed be an independent company.

    The Boring Company has no full-time employees yet, nor does it have a clear business model, though government contracts will almost certainly play a role. Musk says the tunneling business is a bit like the aerospace industry, which he shook up by starting SpaceX in 2002. Rockets hadn’t changed much since the Apollo program, and research projects were slow and expensive. SpaceX differentiated itself by offering low, fixed-price launches, eventually winning a $1.6 billion contract from NASA to run supply missions to the International Space Station.
    Musk points out that as crazy as tunneling sounds, it’s less crazy than Silicon Valley’s go-to traffic solution: flying cars
    Tunnel technology is older than rockets, and boring speeds are pretty much what they were 50 years ago. As with space launches, tunnels are often funded through cost-plus government contracts, in which the contractor assumes no risk for cost overruns, which tend to be enormous as a result. Famously, Boston’s Big Dig, which moved a section of Interstate 93 underground, was delayed by roughly eight years and cost $12 billion more than originally planned, but all tunnels tend to be wildly expensive. In L.A., plans to extend the subway’s Purple Line by 2.6 miles will cost more than $2.4 billion and take almost 10 years. “It’s basically a billion dollars a mile,” Musk says. “That’s crazy.”

    Musk wouldn’t comment on Trump, but a person close to him says that while the Boring Company would be open to building tunnels as part of Trump’s infrastructure plan, it intends to move forward regardless of what happens in Washington. Musk says he hopes to build a much faster tunneling machine and use it to dig thousands of miles, eventually creating a vast underground network that includes as many as 30 levels of tunnels for cars and high-speed trains such as the Hyperloop.

    Objections spring to mind. Such as: Wouldn’t having hundreds of feet of hollow tunnels destabilize the ground? Nope, Musk says, the mining industry does it all the time. “The earth is big, and we are small,” he says. “We are so f---ing small you cannot believe it.” Not only are these megatunnels possible, he argues, they’re the only way we can rid ourselves of the scourge of traffic.

    “We have skyscrapers with all these levels, and we have a flat, two-dimensional road system,” he says. “When everyone decides to go into these structures and then exits them at the same time, you’re going to get jammed.” Tunnels, on the other hand, would represent a 3D transportation network.


    Musk chose the SpaceX parking lot as the site of his first dig, mostly because it was convenient and he could legally do so without city permits. The plan is to expand the current hole into a ramp designed for a large tunnel boring machine and then start digging horizontally once the machine is 50 feet or so below ground, which would make it low enough to clear gas and sewer lines and to be undetectable at the surface. The company, such as it is, is working on securing permits and hopes to have them by the time the tunnel hits the property line. At the moment, Musk won’t say exactly where this “demo tunnel,” as he calls it, will lead—only that it will accommodate cars and be the very beginning of a vast underground transportation network.

    As crazy as tunneling sounds, Musk points out that it’s arguably less crazy than Silicon Valley’s go-to traffic solution: flying cars. Google’s Larry Page has funded two personal-aircraft startups, Zee.Aero and Kitty Hawk, and companies such as Uber and Airbus have skunk works. But Musk thinks flying cars are a dumb idea, at least for city travel. “Obviously, I like flying things,” he says. “But it’s difficult to imagine the flying car becoming a scalable solution.” As long as the laws of physics hold, he explains, any flying car will need to generate a lot of downward force to stop it from falling out of the sky, which means wind and noise for those on the ground, not to mention debris from midair fender-benders. “If somebody doesn’t maintain their flying car, it could drop a hubcap and guillotine you,” he says. “Your anxiety level will not decrease as a result of things that weigh a lot buzzing around your head.”

    Eventually the aide says it’s time for me to ask my last question. But Musk isn’t done. He pulls off his tie, lays it on the table, and looks at me seriously. “You want to come see it?” he asks.

    “Holy shit. Holy shit! Ha-ha-ha-ha!”

    By now the sun is low, and Musk, SpaceX’s Davis, and I are dangling 20 stories in the air, on a large steel platform surrounded by a railing. The “man basket,” as it’s known in the construction business, is being lowered by an enormous crane into a 100-foot-deep shaft not far from the baseball stadium where the Washington Nationals play. I’m freezing and terrified. Musk, with a wide, open-mouthed smile, stares down into the darkness. He wears a safety harness, a hard hat, and knee-high muck boots over the suit he wore when he met the president.

    “Holy shit,” he says again as we step into several inches of sloppy mud. “This is cool.” It’s his first time seeing a tunnel-boring machine up close.

    Musk has brought me to the site of a municipal project to kick the cutting wheels, so to speak, on a used boring machine he’s considering. The machine is 26 feet in diameter, about 400 feet long, weighs 1,200 tons, and is nicknamed Nannie. It’s been used by Washington’s water utility to dig a tunnel to prevent sewage from overflowing into the Anacostia River. New machines normally cost at least $15 million, but a decade of frantic subway construction in China has created a glut, and lightly used models can be had for 90 percent off sticker.

    Nannie, made by the German company Herrenknecht, has been digging only since 2015, but it looks ancient, its surfaces scaled by rust or caked in mud. Although the head looks as you’d expect—like a giant power drill—most of the work happens in the back, where conveyor belts transport mud to the surface, hydraulic pistons brace the wall, and small, narrow-gauge trains haul sections of precast concrete rings to line the tunnel. There are also systems to bring in grout and various foams as well as enormous ducts to pump out exhaust and bring in enough clean air for Nannie’s crew of 15 or so. “This is like an ecosystem,” says Musk.

    He plans to use a machine like this to test improvements in tunneling technology. He thinks that with more power, better materials, and a design that allows it to continue digging while installing the tunnel walls—a feat that’s impossible today—the Boring Company will be able to drastically reduce the price of digging. “To make it a little better should be easy,” he says. “To make it five times better is not crazy hard. To make it 10 times better is hard, but nobody will need to win a Nobel Prize. We don’t have to change the standard model of physics.”

    As we walk through the machine, Musk and Davis pepper the tunnel’s project manager, Shane Yanagisawa, with questions. They ask about grouting materials and staffing, but mostly about speed. Yanagisawa says the limiting factor is muck. Nannie’s conveyor belts can carry only so much dirt at a time. The fastest he thinks the machine can possibly run is 75 millimeters per minute. In a typical week, it moves through 300 feet of clay.

    Musk nods. “We’re trying to dramatically increase the tunneling speed,” he says. “We want to know what it would take to get to a mile a week? Could it be possible?”

    “Wow,” says Yanagisawa, taken aback.

    As Musk puts on his harness and steps back into the man basket for the return trip, he seems only slightly discouraged. “It may make sense to start with something smaller,” he says. “But I think we can simplify this a lot.”

    As any longtime resident of Boston can tell you, tunneling tends to resist optimism. The average bridge or tunnel project costs 32 percent more and takes 22 percent more time than expected, according to Bent Flyvbjerg, a professor at Oxford’s Saïd Business School who studies large-scale infrastructure. The process is slow in part because the machines inevitably bump into unforeseen obstacles, such as boulders. “No matter how many tests you do, how many samples you take, you can’t know exactly what you’re drilling into,” Flyvbjerg says.

    Even so, Flyvbjerg is enthusiastic about Musk’s plan. “I wouldn’t just laugh it off,” he says. He thinks that Musk can speed up tunneling just by doing some simple things, such as having enough spare parts on-site to avoid long waits for repairs. “The construction industry really needs disruption,” he says. “It’s the only sector of the economy that hasn’t improved its productivity in the last 50 years.” Musk, he notes, “has a long track record of disruption.”

    This confidence doesn’t so much stem from anything Musk has said about tunnels, nor from any special tunnel expertise he possesses (i.e., none). Rather, it’s a handicapping of Musk himself: a guy with an uncanny ability to recruit smart people to wildly risky causes, while finding ways to make these causes—the colonization of Mars, an electric car that’s faster than a Ferrari—seem achievable rather than ridiculous. SpaceX’s cheap rockets were perfectly tailored to an effort undertaken by NASA starting in 2004 to privatize missions to the International Space Station; Tesla’s growth was spurred by a tax credit for buyers of electric cars. Both of these policies were created by the George W. Bush administration, then embraced by Barack Obama.

    Musk rarely talked about the job-creating potential of his endeavors during those years, focusing instead on the advantages of electric cars over gas-powered ones and on the sheer awesomeness of space travel. “People are mentioning jobs more these days,” he tells me. “But I sort of take it for granted that if you solve problems, then it takes people to solve them.”

    Lately, he’s been more explicit about the economic impact of his work. “My goals,” he recently tweeted in defense of his relationship with Trump, “are to accelerate the world’s transition to sustainable energy and to help make humanity a multi-planet civilization, a consequence of which will be the creating of hundreds of thousands of jobs and a more inspiring future for all.”

    Musk might be an environmentalist, and Trump might believe climate change is a Chinese hoax, but Musk’s companies employ 35,000 people, many of them working the very sorts of manufacturing jobs that Trump says are key to America’s future. Last year, Tesla began operations at its Reno, Nev.-based Gigafactory, which will eventually be the largest battery plant in the world. SolarCity, the solar panel company that Musk helped start and which recently merged with Tesla, opened a 1.2 million-square-foot factory in upstate New York.

    The Boring Company, Musk suggests, is a natural extension of this: “It would certainly create a lot of jobs.” Then he smirks. “A trillion jobs,” he says. “With a T.”
