Denmark embarks on ambitious plan to create new islands off Copenhagen coast

The Danish government and greater Copenhagen mayors, working with Urban Power architecture and planning, have embarked on an ambitious scheme to create nine new islands off the coast of Copenhagen. The massive land reclamation project will provide new space for leisure and industry use, as well as a lot of energy production.

Boring Company Offers to Dig 30 Mile Tunnel Through Mountains in Australia
Brian Wang | January 17, 2019

 

Elon Musk offered New South Wales parliament member Jeremy Buckingham a tunnel underneath the Blue Mountains to link Sydney to the West.

Previously Elon Musk used twitter to offer Australia battery storage and that utility-scale storage was built. The biggest lithium-ion battery farm in the world was built in South Australia in 2017. This helped prevent blackout problems and Australian lawmakers and local cities from energy problems.

The Boring tunnel would be a competitive price of about $15 million per kilometer. The entire cost of a 50 kilometer (30 mile) long tunnel would be around $750 million. That’s a lot less than the up to $1 billion per mile figure the Boring Company estimates on its website that a tunnel would cost at conventional rates. The idea would be to help Sydney’s notorious traffic.

The Australian State premier will get presented with the offer.

HYPERLOOP PROMISES ULTRAFAST TRANSPORTATION. BUT WHAT DOES IT MEAN FOR THE ENVIRONMENT?

 

https://ensia.com/fe...onment-impacts/

 

Introduction:

 (Ensia) Deep in the heart of steel country on a balmy September morning, Cleveland City Council members, professors and non-profit leaders hopped out of their cars and Ubers and filed into a conference hall to find out why an Ohio transportation agency had taken the unusual step of using public money to pursue an experimental form of electric transportation: hyperloop.

 

Attendees to this transportation workshop were no stranger to new technologies, especially innovations they hoped would make transportation faster and simpler. The Northeast Ohio Areawide Coordinating Agency (NOACA) is part of a “smart city” group already working on adding “internet of things” devices to traffic signals, message signs and traffic cameras in Cleveland and the surrounding region, and Ohio Gov. John Kasich broke ground on a self-driving car test facility in Logan County in July.

 

But hyperloop was another level of innovation for this corner of the Great Lakes region. The ultra-fast, electric-powered transportation technology, still in the research and development stage, is expected by proponents to propel levitating pods full of people and cargo at speeds of up to 750 miles (1,207 kilometers) per hour in a vacuum tube between metropolises.

 

Bel Air billionaire and Tesla co-founder Elon Musk popularized the concept with a 2013 white paper that invigorated transportation-minded entrepreneurs. But Musk didn’t lead the charge on hyperloop. Instead, it has been developed and tested by high-tech engineers who joined new companies that were spun up by Silicon Valley and Los Angeles entrepreneurs.

Welcome To The Abnormalization of Transportation

 

https://techcrunch.c...transportation/

 

Introduction:

(TechCrunch) Something odd is in motion in Los Angeles. On a recent day at the office, colleagues debated the merits of the Boring Company’s proposal to alleviate Dodger traffic via levitating tunnel pods. I stepped out for coffee in the afternoon and was almost run over by an elderly man on a dozen scooters, balanced precariously as he rebalanced dockless inventory. And that night, I sat in traffic on the 10 Freeway listening to commentators discuss Uber’s ostensibly imminent eVTOL aircraft, while a venture capitalist friend rested his head in the sleeping compartment of a Cabin bus, carrying him back to Silicon Valley from Santa Monica.

 

Welcome to the abnormalization of transportation.

 

Even without hover-sleds and flying cars, the Los Angeles megalopolis is in the midst of a transformation in mobility. Neighborhoods from downtown to Silicon Beach have been carpeted in scooters and bikes. The Uber and Lyft revolution faces competition from the various dockless two wheelers and Via’s ridesharing as a service, launching in Los Angeles soon. Flixbus, looking to expand out of European dominance, targeted LA as its hub for inter-city private bus service. And Cabin’s luxury sleeper bus has been offering a premium alternative to Megabus to and from the Bay Area for months.

 

Los Angeles is far from the exception. Autonomous cars are driving people to and from school in Arizona, senior citizens around retirement homes in Florida, and a small army of journalists in an endless loop around Northern California. Starship’s delivery bots have rolled through more than 100 communities, and Kroger shoppers can let Nuro bring them the milk in Scottsdale today. And drone companies from around the world are vying for permission to replace vans and bikes with quadcopters for just-in-time deliveries, while nearly three dozen cities have signed onto the Urban Air Mobility Initiative to make flying cars a reality.

 

If even a fraction of the promise of this technology comes to pass, the movement of things and people in cities will be both bizarre and beautiful process in the near future.

A new method to detect false data injection (FDI) attacks

by Ingrid Fadelli , Tech Xplore

Researchers at Beijing Institute of Technology (BIT) have recently developed a new method to detect false data injection (FDI) attacks on critical infrastructure such as power grids. Their solution, outlined in a paper presented at the 44th Annual Conference of the IEEE Industrial Electronics Society, uses a recurrent neural network (RNN) with several hidden layers, which is harder for FDI attacks to fool.

Cyber attacks on cyber physical systems (CPSs), particularly on infrastructure such as power grids, can cause significant chaos and disturbance for the people living in affected areas. For instance, in December 2015, the hack of a power grid in Ukraine affected over 230,000 people, leaving them without electricity for several hours.

A new vehicle search system for video surveillance networks

by Ingrid Fadelli , Tech Xplore

A team of researchers at JD AI Research and Beijing University have recently developed a progressive vehicle search system for video surveillance networks, called PVSS. Their system, presented in a paper pre-published on arXiv, can effectively search for a specific vehicle that appeared in surveillance footage.

 

Vehicle search systems could have many useful applications, including enabling smarter transportation and automated surveillance. Such systems could, for instance, allow users to input a query vehicle, search area and time interval to find out where the vehicle was located at different times during the day.

In our Wi-Fi world, the internet still depends on undersea cables

 

https://theconversat...ea-cables-49936

 

Introduction:

(The Conversation) Recently a digital blackout in Tonga — caused by the severing of the country’s only undersea cable — generated widespread recognition of the submerged systems our connected world depends upon.

 

Not many people realize that undersea cables transport nearly 100 percent of transoceanic data traffic. These lines are laid on the very bottom of the ocean floor. They’re about as thick as a garden hose and carry the world’s internet, phone calls and even TV transmissions between continents at the speed of light. A single cable can carry tens of terabits of information per second.

 

While researching my book “The Undersea Network,” I realized that the cables we all rely on to send everything from email to banking information across the seas remain largely unregulated and undefended. Although they are laid by only a few companies – including the American company SubCom and the French company Alcatel-Lucent – and often funneled along narrow paths, the ocean’s vastness has often provided them protection. When one is broken, as the Tonga cable was this week, data traffic comes to a halt.

 

Far from wireless

 

The fact that we route internet traffic through the ocean – amidst deep-sea creatures and hydrothermal vents – runs counter to most people’s imaginings of the internet. Didn’t we develop satellites and Wi-Fi to transmit signals through the air? Haven’t we moved to the cloud? Undersea cable systems sound like a thing of the past.

 

The reality is that the cloud is actually under the ocean. Even though they might seem behind the times, fiber optic cables are actually state-of-the-art global communications technologies. Since they use light to encode information and remain unfettered by weather, cables carry data faster and cheaper than satellites. They crisscross the continents too – a message from New York to California also travels by fiber optic cable. These systems are not going to be replaced by aerial communications anytime soon.

oeing Could Build New 797 Jets and Lower Ticket Prices by 40% by mid-2020s
Brian Wang | January 29, 2019
797design-730x430.jpg

 

Boeing will soon decide whether to spend $15 billion to develop a new 797 mid-range passenger jet.

The proposed 797 would have an oval-shaped body that saves weight and fuel. 797 trip costs would be about 40 percent lower than today’s wide-body aircraft. It would have more space to passengers and less to freight in the plane’s belly. A smaller version would seat 220 travelers, while a larger model would seat up to 270 people. The 797 plane family overlap Boeing’s largest single-aisle, the 737 Max 10, and smallest wide-body, the 787-8, is just one question mark.

Singapore, Australia, China, Indonesia ground Boeing's 737 MAX 8 as concerns mount

Source: Reuters


SINGAPORE (Reuters) - Singapore and Australia suspended operations of all Boeing 737 MAX aircraft in and out of their airports on Tuesday, and Indonesia and China grounded their fleets of the U.S. planemaker’ s latest model after it suffered a second fatal crash in less than five months.

The scare has wiped billions of dollars off the market value of the world’s biggest planemaker, as the Boeing Co share closed 5 percent down on Monday having fallen by as much as 13.5 percent at one point.

Nearly 40 percent of the in-service fleet of 371 Boeing 737 MAX jets globally is grounded, according to industry publication Flightglobal, including 97 jets in the biggest market, China.

Sarah Sanders says it's too "early in the process" for US to ground Boeing 737 MAX 8s

Source: CNN


White House press secretary Sarah Sanders on Fox News Tuesday said that it’s too “early in the process” for the United States to ground the fleet of Boeing 737 MAX 8s.

Sanders said the decision will ultimately be a process and that the administration will be in constant contact with the Federal Aviation Administration and the Department of Transportation.

“We know a lot of people in the industry have started to voice concerns about the amount of technology and taking the power out of the hands of the pilots,” Sanders said. “You saw the President talk about that in his tweets earlier today,” she added.

After A $14 Billion Upgrade, New Orleans’ Levees Are Sinking


Sea level rise and ground subsidence will render the flood barriers inadequate in just four years

...now, 11 months after the Army Corps of Engineers completed one of the largest public works projects in world history, the agency says the system will stop providing adequate protection in as little as four years because of rising sea levels and shrinking levees.

Plane with world's longest wingspan takes off and successfully lands – video

 

Sun 14 Apr 2019 12.32 BST

 

A manned giant six-engine aircraft with the world’s longest wingspan – surpassing Howard Hughes’s infamous Spruce Goose – took off from California on its first flight on Saturday. The twin-fuselage Stratolaunch jet lifted off from Mojave air and space port and climbed into the desert sky 70 miles north of Los Angeles. It successfully landed two hours later. The aircraft is designed to carry as many as three satellite-laden rockets under the centre of its enormous wing, which stretches 385ft, or 117 metres.

Electric air taxi startup Lilium completes first test of its new five-seater aircraft
 
May 16, 2019
 
German air taxi startup Lilium announced the first test of its full-scale, all-electric five-seater aircraft. It was the latest in a series of successful tests for the nascent electric flight industry, which aims to have “flying cars” whizzing above cities within the next decade.
 
In a video provided by the Munich-based company, Lilium’s unpiloted aircraft can be seen taking off vertically like a helicopter, hovering briefly, and then landing. It may not seem like much, but it’s a big step for the company, which hopes to launch a fully operational flying taxi service in multiple cities by 2025.
 
Compared to the other preproduction electric aircraft we’ve seen so far, the Lilium Jet certainly stands out: it has an egg-shaped cabin perched on landing gear with a pair of parallel, asymmetrical tilt-rotor wings. The wings are fitted with a total of 36 electric jet engines that tilt up for vertical takeoff and then shift forward for horizontal flight. There is no tail, rudder, propellers, or gearbox. When it’s complete, the Lilium Jet will have a range of 300 kilometers (186 miles) and a top speed of 300 km / hour (186 mph), the company says.

Trump Cancels $929 Million Grant for California Bullet Train

 

By Romy Varghese
May 16, 2019, 9:18 PM GMT+1

 

The Trump administration officially canceled $929 million in federal grants earmarked for California’s ambitious high-speed rail project, escalating tensions between the federal government and the most-populous U.S. state.

Federal Railroad Administrator Ronald Batory said in a letter Thursday to Brian Kelly, the chief executive officer of the state agency running the project, that California has failed to show progress and meet requirements under the agreements for the funds. Governor Gavin Newsom, through a spokesman, vowed a court fight.

"It is now clear that California has no foreseeable plans, nor the capability, to pursue that statewide HSR System as originally proposed," Batory wrote.

Initially conceived as connecting San Francisco and Los Angeles with a high-speed train that would slash travel times and transform the state’s economy, the project has been beset by cost overruns and delays, causing its estimated price to balloon to $79 billion.

California's high-speed rail project was poorly conceived from the start and blew way past the initial cost and timeframe estimates it claimed when voters agreed to it. Its failure should be studied if you want to understand all the factors that hobble America from building large infrastructure projects today, which, as you pointed out, sharply contrasts with China. 

 

I think the U.S. should hire a big Chinese company to build a big bridge or something, just to lets Americans  see firsthand how far behind we've fallen thanks to our obsession with red tape, NIMBYism, labor unions, and environmentalism. Watch China bring in its own workers and get it done under time and at 1/4 the cost of an American crew.
