It's a collaboration between Venturi—a Monegasque electric car company—and the Ohio State University that aims to break 400mph (644km/h) on the Bonneville salt flats while simultaneously acting as a testbed for future electric vehicles and the young engineers who work on it. Fortunately Columbus, Ohio, is less than a day's drive from Washington, DC, so I took advantage and paid the land speed car a visit.<br /> <br /> VBB-3—its nickname—is the third land speed car to come from the Center for Automotive Research (CAR) in Columbus. Its long, thin shape has been dictated by aerodynamics, unencumbered by the draggy intakes required to feed air-breathing engines. It has a pair of electric motors, each good for 1,500 horsepower (1,119kW) and powered by eight large lithium-ion battery packs. Earlier VBBs set records in 2009 and 2010, but last summer terrible salt conditions prevented VBB-3 from running a proper test program to 400mph and beyond.<br /> <br /> Each axle is powered by its own electric motor. The starting point is the same EV motor Venturi builds for its sports cars, running here at a much higher voltage. In fact, there are actually two EV motors in each unit. "It's two motors sharing a cooling system and a common shaft," team leader (and former graduate student) David Cooke told us. "It makes more manufacturing sense to build smaller motors and couple them together than trying to build one big motor. Today that motor is putting out about 1,000 horsepower in the dyno, but it's capable of 1,500." The team is continuing to develop the powertrain—particularly the inverter control—to give VBB-3 the 3,000hp it needs.<br /> <br /> "Motor technology is already there," Cooke said. "The real limit is where you get the energy from." For VBB-3, that means lithium-ion battery packs from A123 (VBB-2 used hydrogen fuel cells). The team—engineering students at OSU, remember—did the rest, integrating them in the powertrain, cooling them, and so on. There's a total of eight battery packs on the car, four on either side of the carbon fiber cockpit tub (enjoying a new life after retiring from its previous career as a Dallara IR03 IndyCar).<br /> <br /> Two battery packs are bussed together and fed into each inverter, the hardware for which is supplied by American Traction Systems. The inverters just look like large metal boxes ahead or behind the wheels, but they convert DC from the batteries into the AC needed by the motors.<br /> <br /> Keeping the motors cool enough during the car's minute-long runs is crucial. "The real limit to how hard you can push the motors is ensuring you don't exceed the temperature limits of the magnets and electrical windings and insulation," Cooke said. "These motors have oil cooling jackets over the stator, and we also pump oil over the magnets for the best possible cooling."<br /> <br /> Radiators would mean vents or intakes, which would in turn mean drag. Therefore VBB-3 has closed-loop cooling systems instead. "We have a water tank we pack full of ice and prechill as much as humanly possible before the race," Cooke explained. (That's all in one big aluminum housing up front.) "This year we also developed an off-board cooling loop for the motors so we have an ATF [automatic transmission fluid] oil chilling circuit that circulates around the motors. We get the motors and inverters down to about 0 degrees Celsius before the start of a run, and they're at operating temperature in around 60 seconds."<br /> <br /> The gearbox—a two-speed—is custom made by Hewland in the UK. "The amount of torque the motors put out—and how quickly they can do it—requires some special things from the transmission. By that point, with a really custom solution we were able to do all the other things we wanted," Cooke said. One of those was hanging the suspensions from the gearbox casing, something you usually see on prototype or open-wheel race cars. "Another neat system we've developed is a fullfull<br /> <br /> <br /> <br /> With carbon fiber relegated to the bodywork, the focus was back on a metal tube frame. Cooke said the design team didn't want to just settle for conventional off-the-shelf 4130 steel, however. None of the more exotic alternatives proved superior. "The maximum weight saving was about 50 lbs, but cost goes through the roof, weldability goes down, and in most of those metals vibration fatigue is terrible," he said. Using aluminum would mean inspecting the frame after every second run to check for fatigue. Magnesium would have been very light but with an incredibly complex welding process. "We're in the middle of the desert, and if there are things we need to fix, it's hard to beat steel tubing."<br /> <br /> VBB-3's design has to take into account a much harsher environment than all the other race cars and bikes built by the students at CAR. Corrosion isn't a problem at the salt flats themselves, but it surely is after spending a couple of weeks there. "One year we hadn't had time to paint the chassis before Bonneville, so we knew we'd have to strip it when we got back. It was covered in salt and water so we power washed it in Utah, and it was beautiful new metal; we got as far as Iowa on I-80 and everything just turned orange—it was like an explosion," Cooke told us.<br /> <br /> Titanium and aluminum are used where appropriate, and Cooke and his team have been exploring advanced coatings for other parts. They work closely with a coatings group in Dayton that does aerospace work, for example, and when visiting we saw a brake system being machined that was destined to be sent away for an advanced nickel coating. "In most cases there are things out there [for a given application], you just get down to practicalities of can we/should we do that," Cooke says.<br /> <br /> Over the winter every nut and bolt comes off the car. "Everything is a prototype system, so we really have to watch everything we can. We'll inspect the entire chassis, do some non-destructive testing on the welds looking for cracks, we'll pull all the battery pack parts apart," Cooke told us. "This year at the race track we saw the most vibration that I think any land speed car has ever seen." Indeed, VBB-3 was the only car to be timed on the Bonneville salt flats in 2015, a consequence of storms that wrecked the surface for speed runs. "By the time we were racing it was dry, but there were soft pockets just underneath the salt. The surface was blowing up like little land mines."<br /> <br /> In 2015, VBB-3's pilot, Roger Schroer, was at least officially timed at 288mph (463km/h). On his final run, he continued accelerating to almost 300mph (482km/h). VBB-3 ended the day bleeding its crimson coolant onto the salt, the extremely bumpy track resulting in a punctured coolant tank. "In general, vibration isn't an issue; if you're going to do 400mph you expect a smoothed, polished course," Cooke said. "We felt 300 was the limit this year." Schroer told the team the ride felt like what it must have been like to take off in a rocket; the vibration was so severe he couldn't focus on the marker flags that lined the course.<br /> <br /> Even if it didn't reach 400mph, Cooke told us that the team still learned a lot last year. "Every 25mph is a new boundary. We increase speed in 25 to 50mph increments so you can look at the data; is the car lifting, are the tires right, is the aerodynamics right?"<br /> <br /> In that light, knocking on the door of 300mph was a big milestone even if the result is not quite as fast as VBB-2.5. "Yes we've been there with previous cars, but this is an all-new car, all-new systems," Cooke said. "I wish we had a bit more time this year with a better track."<br /> <br /> We all hope that 2016 grants Cooke and the rest of the VBB-3 that wish. If so, don't be surprised if there's another 25 to 50mph increment or two to study.<br /> <br /> <br /> <br /> <br /> .<br /> <br /> <br /> <br /> ....<br /> <br /> <br /> <br /> <br /> <br /> <br />

World’s fastest snow sledge is being built in Germany

It's currently held by bike racer Guy Martin at 83.5mph (134.36km/h). But perhaps not for long: over in Germany, Norwegian-based Snowspeed and Toyota Motorsport are working on a carbon fiber sledge that hopes to smash Martin's record by hitting at least 155mph (250km/h).<br /> <br /> Based in Cologne, Germany, Toyota Motorsport GmbH is best known for its World Endurance Championship-winning race team, which took the 2014 crown in a dominant fashion with the 1000-horsepower hybrid TS040. Unfortunately, 2015 wasn't such a great year for the team. Although its revised car was a couple of seconds per lap quicker than the year before, both Audi and Porsche found even more speed, and the team had to settle for third place.<br /> <br /> TMG is developing the new TS050 for this year's WEC, but the company does a lot more than build race cars. One of the ways it spends its considerable engineering and aerodynamics experience is on the Snowspeed, a gravity-powered sledge that looks like a Formula 1 car minus the wheels and wings.<br /> <br /> "Speed skiers already exceed 250km/h and the current speed skiing record is held by Simone Origone, who reached 252.45km/h in 2014. Our sledge will be heavier and more aerodynamic than a skier, so we believe we can go even faster," said Snowspeed team member Jorn Madslien.<br /> <br /> Early tests in TMG's wind tunnel revealed that the current Snowspeed design needs a bit more rear-end stability, and those adjustments will be the team's focus over the next year. "We will improve the design further over the next few weeks and aim to complete the final sledge in the next few months, ready for an attempt at the world speed record in 2017," said Nima Shahinian, Snowspeed's designer.<br /> <br /> We'll continue to follow the project here at be9ja.and will update you when the gravity racer takes to the mountains. No word on whether or not they'll let us take a ride in it, though hope springs eternal.<br />

Granted, the focus has shifted a bit — there are fewer video games than before, making room for pachinko, purikura, crane games, and so on. And some notable locations have been forced to close their doors in recent years. But there's still a vibrant community around the arcade, known as "game center" in Japanese, and enough paying customers for there to justify a giant trade show in the cavernous Makuhari Messe center devoted to new machines.<br /> <br /> That's what JAEPO — the Japan Amusement Expo — is, and that's how I spent my Friday. As you might expect, it was a whole lot of fun, and a much-needed reminder of why I love arcades so much.<br /> <br /> By a cruel twist of fate, JAEPO 2016 is being held the same week as an event that could be seen as a harbinger of a dark future for the industry. Street Fighter V came out worldwide this week, and I've liked my time with it, but I can't help feeling a little sad that it's the first major game in the series not to see release in the arcades first. I moved to Japan right around the time Street Fighter IV hit arcades for the first time, and I have fond memories of getting repeatedly beaten by total strangers while being excited to play a game that you couldn't play anywhere else.<br /> <br /> But who needs Street Fighter? JAEPO has amazing rhythm games, bizarre fishing simulators, cutting-edge photo booths, and tons of Neko Atsume toys. That's pretty much what you'll find in actual Japanese arcades these days as well, save for the smoky floor where hardcore fighting and shooting game enthusiasts hang out. And as long as that stays the case, Japanese game centers will continue to be an awesome place to be.<br />

When you take the long view, preserving humanity's collective culture isn't a marathon, it's a relay — with successive generations passing on information from one slowly-failing storage medium to the next. However, this could change. Scientists from the University of Southampton in the UK have created a new data format that encodes information in tiny nanostructures in glass. A standard-sized disc can store around 360 terabytes of data, with an estimated lifespan of up to 13.8 billion years even at temperatures of 190°C.

A new paper on the format will be given tomorrow by the team's lead researcher, Professor Peter Kazansky, at the Society for Optical Engineering Conference in San Francisco.</div> <div class="separator" style="clear: both; text-align: center;"> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiCriHeRFsN9AQfsvqnisaq7rEDlD0t3fFIlWrHPRdb-f_nVgbqVVzN1Q_nawnHx7s6swLbXIYLgJUfU0TaWSgnqpI_yYHq8SB8IUZPmpgi_YTn1ObBqwks9-YeQyuBUyo32fdozgJhUT4/s1600/Eternal_5D_data_storage_by_ultrafast_laser_writing_in_silica_glass_copies_of_Magna_Carta_Kings_James_Bible_The_Universal_Declaration_of_Human_Rights_and_Newton_Opticks.0.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiCriHeRFsN9AQfsvqnisaq7rEDlD0t3fFIlWrHPRdb-f_nVgbqVVzN1Q_nawnHx7s6swLbXIYLgJUfU0TaWSgnqpI_yYHq8SB8IUZPmpgi_YTn1ObBqwks9-YeQyuBUyo32fdozgJhUT4/s1600/Eternal_5D_data_storage_by_ultrafast_laser_writing_in_silica_glass_copies_of_Magna_Carta_Kings_James_Bible_The_Universal_Declaration_of_Human_Rights_and_Newton_Opticks.0.png" /></a></div> <br /> <div class="separator" style="clear: both; text-align: center;"> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgfE1ShVChFK80b5uQtlLcctat5f9nHzC5dRst2vwazx310mDdCoPnGUFGzRPezya_7UIWGVvd6cHub5Y6ZqSYywlBodfJdmubT8HLFN85H7uC14w1uPjCpBef7hLrC_jaDSt_Aji1FIkA/s1600/Eternal_5D_data_storage_by_ultrafast_laser_writing_in_silica_glass_copies_of_Magna_Carta_Kings_James_Bible_The_Universal_Declaration_of_Human_Rights_and_Newton_Opticks.0.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgfE1ShVChFK80b5uQtlLcctat5f9nHzC5dRst2vwazx310mDdCoPnGUFGzRPezya_7UIWGVvd6cHub5Y6ZqSYywlBodfJdmubT8HLFN85H7uC14w1uPjCpBef7hLrC_jaDSt_Aji1FIkA/s1600/Eternal_5D_data_storage_by_ultrafast_laser_writing_in_silica_glass_copies_of_Magna_Carta_Kings_James_Bible_The_Universal_Declaration_of_Human_Rights_and_Newton_Opticks.0.png" /></a></div> <div class="separator" style="clear: both;"> <br /></div> <div class="separator" style="clear: both;"> <br /></div> <div class="separator" style="clear: both;"> The one-inch discs used to encode new texts in 5D and a diagram illustrating the micron-sized dots (not to scale) which the nanogratings are stored in. (Image credit: University of Southampton)</div> <div class="separator" style="clear: both;"> To understand why these discs can store so much information for such a long time, it's best to compare them to a regular CD. Data is read from a normal CD by shining a laser at a tiny line with bumps in it. Whenever the laser hits a bump. it's reflected back and recorded as a 1; whenever there's no bump, it's recorded as a 0. These are just two "dimensions" of information — on or off — but from them, CDs can store anything: music, books, images, videos, or software. But because this bumpy line is stored on the surface of the CD, it's vulnerable. It can be eroded either by physical scratches and scuffs, or by exposure to oxygen, heat, and humidity.</div> <div class="separator" style="clear: both;"> <br /></div> <div class="separator" style="clear: both;"> 5D discs, by comparison, store information within their interior using tiny physical structures known as "nanogratings." Much like those bumpy lines in the CDs, these change how light is reflected, but instead of doing so in just two "dimensions," the reflected light encodes five — hence the name. The changes to the light can be read to obtain pieces of information about the nanograting's orientation, the strength of the light it refracts, and its location in space on the x, y, and z axes. These extra dimensions are why 5D discs can store data so densely compared to regular optical discs. A Blu-ray disc can hold up to 128GBs of data (the same as the biggest iPhone), while a 5D disc of the same size could store nearly 3,000 times that: 360 terabytes of information.</div> <div class="separator" style="clear: both;"> <br /></div> <div class="separator" style="clear: both;"> These discs can potentially last for so long because glass is a tough material which needs a lot of heat to melt or warp it, and it's chemically stable too. (Think about all those science experiments that use glass beakers to contain reactive materials without anything bad happening to them.) This makes the 5D discs safe up to temperatures of 1,000°C, say the researchers.</div> <div class="separator" style="clear: both;"> <br /></div> <div class="separator" style="clear: both;"> <br /></div> <div class="separator" style="clear: both;"> <br /></div> <div class="separator" style="clear: both;"> 5D data storage obviously has potential as an archival format for museums and galleries, but the scientists involved believe it could be also be commercialized in the not-too distant future.
