I transloaded for a space ahead of me, to have the reverse atomic mass meet me.

The Best Way Through the Alps Is the World’s Longest Rail Tunnel

Compared to the 160 million years the Alps have spent climbing out of the violent collision of the Eurasian and African tectonic plates, Switzerland’s 17-year project to blast through them doesn’t seem lengthy at all. But the feat fits the scale of the snow-capped mountains: When it opens today, the Gotthard Base Tunnel will be the longest, deepest rail tunnel in the world, spanning 35 miles and dipping to 1.4 miles below the surface. It’s a majorly challenging and ambitious infrastructure project for a small country perhaps best known for chocolate.

...

The Gotthard Base Tunnel, which can accommodate 260 freight trains a day, is only the first part of a plan to rehaul the way Europe, well, hauls. With the help of the another mammoth tunnel to its south, set to open in 2020, Gotthard is a critical part of the revitalization of the Rotterdam to Genoa rail network. The continuous flat route will connect the bustling northern Dutch port to the Mediterranean, meaning freight can blast through Europe at unprecedented speeds. Meanwhile, Austria, the Italian and German Alps, and the French city of Lyons all have green lights for their own major underground projects. By 2030, getting around Europe will be much faster, especially if you’re a large shipping container of, say, stroopwafels.

The Lamborghini Veneno is a limited production supercar based on the Lamborghini Aventador and was built to celebrate Lamborghini’s 50th anniversary. When introduced in 2013 at a price of US$4,500,000, it was the most expensive production car in the world.[53] The prototype, Car Zero, is finished in grey and includes an Italian flag vinyl on both sides of the car. The engine is a development of the Aventador's 6.5 L V12 and produces 750 PS (552 kW; 740 bhp).[54][55]

Lamborghini built just five examples of the Veneno: Two for itself and three for the customers. Car Zero, which was the vehicle on display,[56] will be retained by the factory for the museum. The three production cars cost €3,120,000 each, and all three were sold.[57]

The vehicle number 0 was unveiled at the March 2013 Geneva Motor Show,[58] followed by 2013 Quail Motorsports Gathering,[58] Vallelunga circuit near Rome during the World Finals of Lamborghini Super Trofeo 2013 series.[59] There's another number 0 Veneno prototype test car.

I had seen something on this a year ago. It's cool it's finally open. Great engineering project. Fingers crossed.

Flying cars just took a big step closer to being legal

It looks like a goofy mosquito, its fat cockpit shoving through the wind while aloft, its wings folded up like a dragonfly while grounded. And it marks the biggest step toward a real, commercial flying car.

The Terrafugia Transition earned an exemption Sunday from the Federal Aviation Administration as a “light sport aircraft,” meaning the federal government is on track to legalize the first flying car.

After a few more rounds of audits and paperwork, the Transition, a two-seated flying thingamajig, can take to the skies under the command of sport pilots, a low-threshold classification. Terrafugia can also commercially produce the aircraft without repeated burdensome federal airworthiness tests.

Flying car industry executives say their products should enter the consumer market -- albeit at a high price -- in the next decade.

Given the average driver, flying cars will be great.

Thanks to gravity there will be no need for flying tow trucks.

Hilarious. Duplicate or triple critical systems are a must.

Aircraft systems may be quadruplexed (four independent channels) to prevent loss of signals in the case of failure of one or even two channels.

If one of the flight-control computers crashes, or is damaged in combat, or suffers from "insanity" caused by electromagnetic pulses, the others overrule the faulty one (or even two of them), they continue flying the aircraft safely, and they can either turn off or re-boot the faulty computers.

Airbus and Boeing commercial airplanes differ in their approaches in using fly-by-wire systems.

In Airbus airliners, the flight-envelope control system always retains ultimate flight control when flying under normal law, and it will not permit the pilots to fly outside these performance limits unless flying under alternate law. However, in the event of multiple failures of redundant computers, the A320 does have a mechanical back-up system for its pitch trim and its rudder. The A340-600 has a purely electrical (not electronic) back-up rudder control system, and beginning with the new A380 airliner, all flight-control systems have back-up systems that are purely electrical through the use of a so-called "three-axis Backup Control Module" (BCM)

With the Boeing 777 model airliners, the two pilots can completely override the computerized flight-control system to permit the aircraft to be flown beyond its usual flight-control envelope during emergencies. Airbus's strategy, which began with the Airbus A320, has been continued on subsequent Airbus airliners.

I am more concerned by the drivers. :)

In many safety-critical systems, such as fly-by-wire and hydraulic systems in aircraft, some parts of the control system may be triplicated, which is formally termed triple modular redundancy (TMR). An error in one component may then be out-voted by the other two. In a triply redundant system, the system has three sub components, all three of which must fail before the system fails. Since each one rarely fails, and the sub components are expected to fail independently, the probability of all three failing is calculated to be extraordinarily small; often outweighed by other risk factors, such as human error. Redundancy may also be known by the terms "majority voting systems" or "voting logic".

A more reliable form of voting logic involves an odd number of three devices or more. All perform identical functions and the outputs are compared by the voting logic. The voting logic establishes a majority when there is a disagreement, and the majority will act to deactivate the output from other device(s) that disagree. A single fault will not interrupt normal operation. This technique is used with avionics systems, such as those responsible for operation of the Space Shuttle.
