It’s A Plane… It’s A Train… Um… It’s Both?

What kind of electric vehicle travels at 620 miles per hour (998 km/h)? According to Canadian and French company TransPot, their FluxJet will do it and they want to use it to virtually shrink the Great White North. An electric jet? Not exactly. The FluxJet is a magnetic levitation (maglev) train riding in a vacuum tube with contactless power delivery.

The company claims it can carry 54 passengers or 10 tons of cargo. You can see two videos about the concept below. Judging by the second video, the device might be controlled by a serial port — well, probably not, but we were still amused to see the directory of tty devices on the screen.

Pipe dream (no pun intended)? Maybe. But they did get $550 million in funding and a plan to build a line between Calgary and Edmonton that will take 45 minutes to traverse. Reports are that they did demonstrate a 1-ton 18-foot-long prototype, although we couldn’t find any actual video footage of that — just hints of it in the marketing videos.

Of course, this isn’t the first such system proposed as a “hyperloop” but they do seem to be building momentum financially. We aren’t clear what they are talking about with the “veillance flux,” but we also know that since they are a French-speaking organization, it may just be another way to say “sensors” because — we think — veillance is a French word that means watching. We also aren’t sure how a train in a vacuum has much in common with an airplane. Maglev isn’t new, either.

Hyperloop: Fast, But At What Cost?

December 9, 2020 by Lewin Day 162 Comments

When it comes to travelling long distances, Americans tend to rely on planes, while the Chinese and Europeans love their high speed rail. However, a new technology promises greater speed with lower fares, with fancy pods travelling in large tubes held at near-vacuum pressures. It goes by the name of Hyperloop.

Virgin Hyperloop recently ran the first-ever passenger test of a Hyperloop vehicle, reaching 100 mph on a short test track.

Spawned from an “alpha paper” put together by Elon Musk in 2013, the technology is similar to other vactrain systems proposed in the past. Claiming potential top speeds of up to 760 mph, Hyperloop has been touted as a new high-speed solution for inter city travel, beating planes and high speed rail for travel time. Various groups have sprung up around the world to propose potential routes and develop the technology. Virgin Hyperloop are one of the companies at the forefront, being the first to run a pod on their test track with live human passengers, reaching speeds of 100 mph over a short 500 meter run.

It’s an exciting technology with a futuristic bent, but to hit the big time, it needs to beat out all comers on price and practicality. Let’s take a look at how it breaks down.

Hackaday Links: January 21, 2018

You know what next week is? Sparklecon! What is it? Everybody hangs out at the 23b Hackerspace in Fullerton, California. Last year, people were transmuting the elements, playing Hammer Jenga, roasting marshmallows over hot resistors, and generally having a really great time. It’s the party for our sort of people, and there are talks on 3D projection mapping and a hebocon. I can’t recommend this one enough.

The STM32F7 is a very, very powerful ARM Cortex-M7 microcontroller with piles of RAM, oodles of Flash, DSP, and tons of I/O. It’s a relatively new part, so are there any breakout or dev boards for it? Sure thing. [satsha] used a desktop CNC mill to create what is probably the simplest possible breakout board for the STM32F7. There’s not much here — just some parts for power and a few LEDs — but this is all you need to get one of these powerful chips up and running.

It’s cold and dark and you can’t fly RC airplanes in January. It’s not because planes and quadcopters don’t work in the cold (they should work better, but I’d love to see a graph of battery temperature and density altitude), it’s that your hands don’t work in the cold. What’s the solution? Just strap some motorcycle handwarmer thingies onto your transmitter. With a 2200 battery strapped to the back, you’ll get about an hour of runtime for these handwarmers.

The BBC is reporting the latest advancement in Hyperloop technology. Is it a fundamentally different way of digging tunnels that isn’t simply scaling down the size of tunnel boring machines? No. Is it improvements in material science that would allow the seals on a 500-mile-long steel pressure chamber to exist? No. Does this latest advancement mitigate the ‘hillbillies with guns’ problem that would turn every Hyperloop car into a literal bullet screaming towards one of the most spectacular deaths possible? No. The chief executive of the Virgin Hyperloop project has something better in mind. A smartphone app, “that would connect future Hyperloop passengers with other modes of transport on arrival.”

Take A Look At The Hyperloop Competition Entries

If you are a follower of futuristic high-speed transport systems you’ll have had your fill of high-speed trains, you’ll mourn the passing of Concorde and be looking forward to future supersonic passenger aircraft. Unless you have a small fortune to pay for a spaceplane tourist flight at an unspecified time in the future, life is going to feel a little slow.

There is one spark of light in this relative gloom though, in the form of Elon Musk’s Hyperloop. A partially evacuated tube in which vehicles, or “pods” can accelerate to very high speeds. SpaceX may not be pursuing it themselves, but they’ve made it available for others and to promote it they are running a competition in which they have invited teams to submit pod designs. And as a significant number of teams have made it through the first round and are prepared to compete outside SpaceX’s headquarters, Business Insider have a look at all the teams and their prototype pods.

Hyperloops And Robot Cars, A Glimpse Into The Future

April 6, 2016 by Gerrit Coetzee 40 Comments

His mobile blooped at him with one of those noises a company spent money to get. A timer started on the screen as he rushed to put his shoes on. He finished and pushed open his door, running down the stairs two to a bound. By the time he reached the bottom of the stairs he had his backpack slung over both shoulders, which he mentally cursed himself for since he’d just have to take the dang thing off again.

It was morning on January first, and he was due at his parent’s house for a new year’s dinner fifteen hundred miles away. He should have booked a plane weeks ago, but now the Loop was his only option. The Loop didn’t really have peak rates, and while the plane would be a little faster, more direct, and cheaper IF he had remembered to book it in time, the Loop would take him the same distance today. Plus, the seats were comfier. They reclined nicely, and he intended to nap on the way. Hopefully, by the time he got there, the bleariness from last night’s celebration would be undetectable by parental senses.

He locked the door to his apartment complex, a reassuringly square assembly from the seventies, and walked to the sidewalk where a friendly light blue car waited for him. When he got close, his mobile vibrated and made another distressingly cheery noise. The doors of the car swung open opposite of each other to expose the space inside. The car displayed two rows of inward facing bench seats, a panoramic row of windows around the entire perimeter of the vehicle, and… yes, his nose was telling him before his eyes fixed on it, a very unsettling amount of vomit in the center of the floor.

He turned around, a bit squeamish, and took out his mobile. He navigated through the controls. Where is the menu option? What year is it now? Why is this still hard? Three awkward menus deep and he finally found and selected the option to let the dispatch know the car had an issue which made it uninhabitable. The car immediately began to chirp warnings and the doors soon started to close. In a moment, a human somewhere in the city would be looking at a video of the inside of the car, determining him a liar or not. As expected, a few seconds later, the little car began to drive off. The lights on the rear of the car turned from bright red to the yellow amber of headlights as it decided its front would be its back. It drove off to the dispatch center for cleaning and repair. Someone would be eating a 100 dollar cleaning bill today. He didn’t feel sorry for them.

His phone began to vibrate. He picked it up to answer a call from a bored customer service representative who was trying hard to sound earnest. “Sorry for the trouble sir, the ride today will be free. We have another car on its way”

Adafruit is working on a series of videos that’s basically Sesame Street for electronics. G is for Ground is out, where [Adabot] discovers pipes and lightning rods are connected to ground. Oh, the rhyming. Here’s the rest of the videos so far. We can’t wait for ‘Q is for Reactive Power’.

Think you’re good enough to build an airlock 70 cubic meters in volume that can cycle once every thirty seconds? How about building a 500 mile long steel tube with zero expansion joints across active fault lines? Can you stop a 3 ton vehicle traveling at 700 miles per hour in fifteen seconds? These are the near-impossible engineering challenges demanded of the hyperloop. The fact that no company will pay for this R&D should tell you something, but that doesn’t mean you still can’t contribute.

Calling everyone that isn’t from away. [Paul] lives near Augusta, Maine and can’t find a hackerspace. Augusta is the capital of the state, so there should be a hackerspace nearby. If you’re in the area, go leave a message on his profile.

Last week we found memristors you can buy. A few years ago, [Nyle] found them while hiking. They were crudded up shell casings, and experiments with sulfur and copper produced a memristor-like trace on a curve tracer.

Need a way to organize resistors? Use plastic bags that are the same size as trading cards.

The Arduino is too easy. It must be packaged into a format that is impossible to breadboard. It should be shaped like a banana. Open source? Don’t need that. The pins are incorrectly labelled, and will be different between manufacturing runs.
