VW is providing electric powertrains to convert classic Beetles

https://www.autoblog.com/2019/09/05/volkswagen-eclassics-e-beetle-electric-conversion-official/

When Volkswagen revealed the ID. Buggy, it also noted that the company was looking into producing electric powertrains for specialty companies that could build unique EVs similar to the Buggy. Now we get to see one of the fruits of VW’s efforts with the eBeetle, or eKäfer in German. It has been developed in part with a Stuttgart-based EV conversion company called eClassics. Classic VWs converted to electricity aren’t new, but the fact that this uses a complete VW electric powertrain is.

Replacing the air-cooled flat-four-cylinder engine is the electric motor and single-speed transmission from the VW e-Up! That motor produces 81 horsepower and 155 pound-feet of torque. That’s significantly more than any Beetle had new. The eBeetle is heavier than a gas-powered Beetle, though, with a curb weight of 2,822 pounds. A large portion of that is likely due to the 36.8-kWh battery pack, which is slightly less than twice as much capacity as the e-Up! that shares its powertrain. Interestingly, the new powertrain appears to have freed up some cargo space in the back, with the motor assembly hidden behind a metal panel.

Volkswagen says the eBeetle should be able to go from 0 to 50 mph in a bit over 8 seconds, which isn’t fast, but is pretty solid for a classic Bug. It has a top speed of 93 mph and an estimated range of 124 miles. It also features DC fast charging capability, so it can pick up a 75% charge in about an hour from a fast charger.

If you want one of these electric Beetles with VW hardware, you’ll have to get in touch with eClassics in Germany. But we expect availability of aftermarket VW electric powertrains will increase over time, as the company is committed to this sector. It’s apparently working on a package for the VW Bus, and it hasn’t ruled out developing a version for Porsche 356 sports cars. The company also said it would look into using MEB components in the future, which are the bits being used for the soon-to-be-revealed ID.3, Buzz, et al. There’s more potential performance in the MEB parts, too, as the base ID.3 is expected to have 168 horsepower, and variations are supposed to have even more grunt.

If going to Germany or waiting for more VW-supported conversion availability doesn’t work, there are other companies offering ways to convert air-cooled Volkswagens. Zelectric offers complete, turnkey conversions, though they’re a bit pricey. For DIY-ers, EV West has a selection of complete kits and EV components to create your own electric VW, as well as a number of other vehicles.

This Huge Electric Dump Truck Never Needs to Plug In

https://www.wired.com/story/this-huge-electric-dump-truck-never-needs-to-plug-in

There’s an electric dump truck that’s all over the internet right now: It’s called the eDumper. What’s so great about an electric dump truck? Beyond being electric, there are two cool things about it. First, it’s huge—HUGE. It has a weight of 45 tons. Second, it doesn’t need an external power source to charge the batteries. It charges itself by moving a bunch of rocks down an incline. That is indeed awesome. But how does it work?

Regenerative Braking

One feature of this electric dump truck is it uses is regenerative braking. Actually, many electric vehicles do this. It’s a way for the vehicle to recover some energy as it slows down. Here’s how it works.

Let’s start by considering an electric motor. If you have electric current running through a wire, it creates a magnetic field. Since the electric current makes a magnetic field, it will interact with other magnetic fields—like the one a permanent magnet creates. By forming this wire into a loop, you can get a torque on this current so that it spins. Boom. That’s an electric motor. Here, you can build one yourself—it’s not too difficult.

But wait! There’s more. If you reverse this process, you can turn this motor into a generator. (A changing magnetic field will create an electric current.) Take a look at this short demonstration. By moving this magnet into a coil of wire, the changing magnetic field makes a current that is measured by this sensitive current meter.

A rotating coil of wire is perfect in this case because you need a changing magnetic field to generate current. As the coil flips over, the magnetic field through the coil changes—that’s exactly what you need. But there you go, an electric motor and an electric generator are the same thing. It just depends on how you use it. If you run current through it, it will turn and you get a motor. If you turn the coil, you get current.

Divinity: Original Sin 2 Has Cross-Saves Between Switch And PC–That’s A Big Deal

https://www.gamespot.com/articles/divinity-original-sin-2-has-cross-saves-between-sw/1100-6469650/

Nintendo and Larian Studios announced and surprise-released Divinity: Original Sin 2 on Nintendo Switch today, September 4, and it includes what could be the first instance of a particular feature.

The game supports cross-saves between Nintendo Switch and Steam on PC. That is a big deal because it appears to be the first, or among the first Switch games, to allow that.

With cross-saves, people can play at home on PC and then pick up where they left off on Switch when they’re out and about. Divinity: Original Sin 2 is a very long game, so those who started on PC but didn’t finish, and now want to play on Switch, can do so as well keeping their saves.

Divinity: Original Sin 2 is out now on Switch, so players can start taking advantage of the cross-save functionality right away. For now, Divinity: Original Sin 2 only supports cross-saves between Switch and PC; there is no cross-save support with PlayStation 4 or Xbox One.

All Divinity: Original Sin 2 players are getting a special treat, as Larian Studios is handing out a "Gift Bag" of free DLC on every platform. The new gift bag, which follows a previous release earlier this year, comes with new recipes and items to craft, a new icon on the hotbar that lets you toggle sprint on and off, and an "Animal Empathy" feature that lets you talk to animals without spending talent points to do. Also new in the DLC is a Magic Mirror, located in the Arena of Fort Joy, that lets you respect before moving to a new act of the game. On top of this, Larian is giving everyone an increase to their base maximum action points to 8. Finally, there is now a herb garden in the game that players can use to grow plants.

For more on the September Nintendo Direct, check out all the big news in our recap.

Android 10 transforms hearing aids into Bluetooth headsets

https://www.engadget.com/2019/09/03/android-10-transforms-hearing-aids-bluetooth-headsets/

In addition to features like a system-wide dark mode and more granular privacy controls, Android 10 is adding new accessibility features. One of the highlights is designed to help those who wear hearing aids to get the most out of their Android smartphone. Using a new protocol called Audio Streaming for Hearing Aids (ASHA), hard of hearing individuals will be able to use their Pixel smartphone to stream audio, including both music and calls, directly to their hearing aids — essentially making them function like any other Bluetooth headset. What’s more, the streaming is done over Bluetooth Low Energy (BLE), so both hearing aids and phone can have enough battery power to get through an entire day.

At launch, the functionality is compatible with the Pixel 3, Pixel 3 XL, Pixel 3a and Pixel 3a XL in conjunction with ReSound LiNX Quattro and Beltone Amaze hearing aids, as well as the Cochlear Nucleus 7 sound processor. Google is also open-sourcing the platform, which should hopefully mean a greater number of Android devices and hearing solutions will support the feature in the near future.

Over the last year, Google has put significant effort toward making Android more accessible to hard of hearing individuals. In February, the company released an app called Sound Amplifier that essentially transforms an Android smartphone into a hearing aid. This past July, the company expanded the availability of the app to include non-Android 9 Pie devices. The need for these type of apps and feature is clear. According to the World Health Organization, some 466 million people globally suffer from disabling hearing loss, with that number growing by the millions every year.

Cowboy’s first e-bike solves the removable battery problem

https://www.engadget.com/2019/09/03/cowboy-electric-bicycle-battery-review/

Electric bicycles usually come in two flavors: either a gorgeous two-wheeler with a non-removable battery inside the frame, out of sight, or a design-be-damned mode of transportation that has the battery stuck to its frame like a hideous torpedo. Form or function? That’s the decision most prospective e-bike buyers have to make. With the Cowboy, though, there’s no compromise. The Brussels-based startup has managed to crack this age-old problem with a sleek but detachable battery that slides behind the seat post. It’s a novel solution that immediately elevates the bike above most of its rivals.

At any distance, this city-centric bicycle looks fantastic. I love the dark gray finish and the shape of the frame, which consists almost entirely of straight, angular lines. It’s an undeniable head turner that should appeal to fixie-riding hipsters and office folk alike. The battery is always visible and, curiously, has a slightly darker finish than the frame. Its positioning, though, means it’s less noticeable than the removable battery on most e-bikes. If I hadn’t told my friends and family beforehand, I’m not sure they would have noticed that the Cowboy was electrified (not until they stepped on and started riding the thing, anyway).

The oval-shaped lights, which are neatly integrated into the frame and battery, give the bike some futuristic flair. It all comes together in a package that feels both vintage and straight from a science fiction movie like Blade Runner. I can honestly imagine Rick Deckard as a still-in-training police officer, riding one of these around the rain-soaked streets of Los Angeles, wondering when he’ll finally receive his iconic Spinner.

I was floored by the bike’s rapid acceleration.

Style means nothing, though, without performance. Cowboy’s first e-bike has a 250W rear-hub motor and, by default, a top speed of 25KMH (15.5MPH). That’s pretty standard across the industry, because for now that’s the maximum allowed in Europe. Still, companies have different ideas about when, and how much, the motor should step in and help you reach that ceiling. Cowboy’s take is surprisingly aggressive, especially at lower speeds. I was floored by the bike’s rapid acceleration whenever I entered a roundabout or pulled away from a previously red light. And if you’re still not happy, there’s an off-road mode that increases the top speed to 30KMH.

Otherwise, there’s little to think about while riding the bike. The assistance is entirely automated, so you don’t have to worry about gears or power levels. The Cowboy uses two integrated torque and speed sensors that, combined with an "optimized algorithm," know how hard you’re pedaling and what, if anything, you need from the motor. Relinquishing control can be tough if you’re used to a traditional bicycle with plenty of front and back gear combinations. I sometimes wanted a higher gear, for instance, so I could continue pedaling down steep hills.

Cowboy e-bike

It’s a small quibble though. The bike is agile and smooth, with no noticeable judder when the motor kicks in. There’s no front or rear suspension though — this is a commuter bike, after all. If you ride off the sidewalk or over a massive pothole, your buttocks are going to know about it. I had no issues with the saddle, though, or the rubber-and-glass-fiber belt, which is cleaner than an oily chain and likely more durable.

The Cowboy weighs 16KG (35 pounds), which is lighter than other e-bikes I’ve tested, including the VanMoof Electrified S2 and the fast-folding Gocycle GX. The weight is comparable to other commuter-style bikes but noticeably heavier than fixies and carbon-fiber racing types. I wouldn’t want to drag it up a flight of stairs every day.

The battery often detaches with a bit of a thud.

It’s a good thing that the battery is removable, then. The oblong power pack requires a key to unlock and separate from the bike. The lock itself can be a little stiff, and the battery often detaches with a bit of a thud. I’m not surprised that the company has added a rubberized material to the part of the frame where the battery normally lands; without it, I suspect the bicycle would quickly scratch. Regardless, it’s a straightforward process, and the included charger, while large, can be plugged into any socket at home.

The battery takes roughly 3.5 hours to replenish and offers up to 70KM (43 miles) on a single charge. That range will vary, of course, depending on the effort you exert and the number of hills you tackle. If you live in a relatively flat city, though, you can theoretically ride four miles both to and from work, Monday through Friday, without recharging.

Cowboy e-bike

If you want to ride a Cowboy, you’ll need the company’s mobile app. That key I mentioned before? Its only purpose is detaching the battery — you can’t use it to turn on the bike. And unlike VanMoof’s electrified rivals, there’s no way to unlock the Cowboy with an old-fashioned passcode.

To start riding, you have to dig out your phone, open the Cowboy app, make sure Bluetooth is enabled and then long-press the pink padlock icon. Compared to a regular bike — which you can jump on and ride in a jiffy — it feels strangely slow and cumbersome. At the bare minimum, I would like the option to unlock the Cowboy via Bluetooth proximity. And what happens if your phone runs out of charge? Get ready to push your bike home, I guess.

The bike has a built-in SIM card and GPS tracking.

Don’t be fooled by the app’s padlock icon either. If you choose to "lock" the Cowboy, you’re merely switching off the motor. That means unless you’re carrying a traditional bike chain or D-lock (and let’s be honest, you absolutely should), any thief can still swing their leg over the frame and ride off. It’s tough to pedal without the assistive motor — I should know, because I’ve forgotten to unlock the bike a few times — but anyone in half-decent shape could power through.

To combat potential thieves, the bike has a built-in SIM card and GPS tracking. Unfortunately, the latter isn’t active all the time: If you lock your Cowboy and walk off, it will simply show its last-seen position in the app. If you suspect your bicycle has been stolen, though, you can tap Find My Bike and see its current location. The feature is only meant for emergencies though. Tapping the appropriate icon in the app brings up two warning screens with confirmatory text such as "Are you sure your bike has been stolen?"

Cowboy e-bike

It’s an understandable limitation that’s meant, presumably, to conserve battery life. Still, I can’t help but feel disappointed. There’s a brick-and-mortar bike shed, for instance, roughly 10 meters from my apartment block. I would love to store the Cowboy there and then periodically check in to make sure it’s OK. The company does, however, offer live theft notifications through its Easy Rider subscription service. The Standard tier, which costs €8 (roughly $9) per month, comes with theft insurance and "fast lane" customer support too. The Plus version, meanwhile, is €10 (roughly $11) per month and adds damage insurance to the Standard perks.

Cowboy’s must-have companion app is, at least, clean and thoughtfully designed. By default, the home screen has a map that shows your position and the last-known whereabouts of your e-bike. Once you’ve gone through the unlock process, the app will reveal a collapsible tab with some basic ride information. In its smaller form, this includes the remaining charge, an estimated distance for that charge, your current speed, the power output of the motor and three shortcuts for locking the bike and activating the motor and the integrated lights. Swipe up and the tab will reveal a little more information, such as the distance covered and time elapsed during your current ride. The charge and power levels, too, are represented by curved lines similar to a speedometer’s.

The Cowboy is one of the best e-bikes I’ve ever tested.

The app is packed with other useful features, such as an auto-off timer, two different ride modes, live chat with Cowboy’s customer support and a history of your previously completed rides. The app is also designed to be used while riding. The bike doesn’t come with a smartphone holder, however, so you’ll need to buy a third-party accessory such as a Quad Lock if you’re interested in this.

The Cowboy is one of the best e-bikes I’ve ever tested. To ride one of these machines full-time, though, I would need to live in a country where the bike is sold. For now, that’s limited to Belgium, France, Germany, Luxembourg and the Netherlands. I would also have to save up €1,990 (roughly $2,198), which is undeniably expensive. That price tag is in line with other city-centric e-bikes though. VanMoof’s Electrified S2 and X2, for example, both have an early bird price of €2,798 (roughly $3,090) at the moment, while the electric Brompton and fast-folding Gocycle GX will set you back £2,595 (roughly $3,159) and £2,899 (roughly $3,529), respectively.

Cowboy e-bike

The Cowboy can’t fold, but its removable battery and excellent acceleration make it an appealing option. The question, as always, is whether you’ll ride any e-bike enough to justify its high price tag. If you can replace most of your car journeys with a motorized two-wheeler, the answer might be yes. Otherwise, you might want to consider some cheaper but shorter range forms of electric transportation. You can buy a whole host of battery-equipped scooters, for example, including the luxurious Boosted Rev, and skateboards, such as the vlogger-standard Boosted Plus, for less than $2,000. Just how badly do you want to pedal?

SpaceX wouldn’t move its satellite despite collision warning, ESA claims

https://www.engadget.com/2019/09/03/spacex-satellite-collision-esa/

There’s a high-stakes traffic issue in the space around our planet. The European Space Agency’s Aeolus Earth observation satellite had to perform a maneuver to prevent collision with SpaceX’s Starlink satellite 44.

ESA experts calculated there was a 1 in 1,000 chance of a collision between the two satellites occurring, as reported by Forbes. That’s a slim chance, but it was enough for the ESA to decide to intervene.

"We informed SpaceX, who replied and said that they do not plan to take action," Holger Krag, head of the Space Debris Office at ESA, told Forbes. The SpaceX satellites should have automated collision avoidance systems, but this system was not used and it’s not clear why.

Instead, ESA’s Aeolus satellite fired its thrusters to move away from the area, half an orbit before the potential collision would have occurred. In the future, the ESA plans to automate the process of satellite collision avoidance using AI. For now though, the engineers there perform the adjustments manually.

"It is very rare to perform collision avoidance maneuvers with active satellites," the ESA said on Twitter. "The vast majority of ESA avoidance maneuvers are the result of dead satellites or fragments from previous collisions."

The ESA satellite occupied this particular region of space nine months before the Starlink satellite arrived. However, there are no laws about space traffic and what regions satellites can occupy. This incident highlights the need for an organized international approach to space traffic.

"We are not upset by them saying [they wouldn’t move]," Krag also told Forbes. "My concern is how often will we have such events in the future? These are just two satellites. Now they will add several thousand, and they will also be disposed and end up at various altitudes. And there’s no rule or law on how to react, it’s all goodwill."

This is not the time the Starlink project has been in the news. Previously, astronomers complained that the launching of the satellites caused problems for telescopes. The satellites’ solar panels made them extra reflective and bright in the sky, though this was lessened once they were oriented correctly.

SpaceX also lost control of three of its Starlink satellites during the first month after launch. While these few satellites likely burned up in the atmosphere, the failure rate raised concerns about future expansions of the project. If SpaceX does launch its planned 12,000 satellites for the Starlink project, the number of lost satellites could cause problems with space debris.

Part cow, part… bacterium? Biotech company makes heifer of gene-editing blunder

https://arstechnica.com/?p=1560849

A Holstein calf, which has not been gene-edited.

A Holstein calf, which has not been gene-edited.

A Minnesota-based gene-editing company is left red in the face after it took on bull genetics—and got slammed.

The company, Recombinetics, set out years ago to genetically engineer Holstein dairy cattle to come without their troublesome horns, which farmers typically remove to keep themselves and other cows safe. In 2015, the company seemed to have succeeded, unveiling two hornless bulls, Spotigy and Buri. Recombinetics touted them as a bona fide, 100%-bovine success story.

Though Spotigy was sacrificed for research, Buri lived on to sire 17 offspring—one of whom graced the cover of Wired, as MIT Technology Review notes. And, until just a few months ago, Brazil was set to create a herd of hornless Holsteins from shipments of Buri’s sperm, Wired reported.

But the plans were bucked after scientists at the Food and Drug Administration stumbled upon an utterly damning find earlier this year—Buri isn’t all bull: he’s a wee bit bacterium.

Bullish edits

When Recombinetics edited the cow cells that would later give rise to Buri, the company did so using bacterial DNA-editing machinery—which inadvertently got stitched into Buri’s genome.

The machinery involved are called TALENs (transcription activator-like effector nucleases), which are enzymes that can be customized to snip a targeted spot in a genetic code. That break in the code can then be patched up with a desired DNA sequence—say, a stretch of DNA that leads to hornlessness, swiped from other, hornless cattle breeds.

Recombinetics’ scientists used a standard method to get the TALENs into the cow cells—they delivered the TALENs via a loop of bacterial DNA called a plasmid. Usually, after the plasmid-encoded TALENs do their snipping, the plasmid’s work is done and it doesn’t hang around. But in Buri’s case, the whole plasmid ended up inserting itself into the bull’s genome, right next to the inserted stretch of DNA for hornlessness.

That means that Buri’s genome contains the entire DNA sequence of the plasmid. And in addition to all the bacterial-editing machinery from the loop of DNA, Buri’s genome includes the antibiotic resistance genes present on the plasmid, too—though they’re unlikely to have any affect.

Blind spot

The plasmid insertion is a big cow plop. But the fact that the company didn’t find the problem itself is perhaps more embarrassing.

“It was not something expected, and we didn’t look for it,” Tad Sonstegard, CEO of Acceligen, a subsidiary of Recombinetics that owns the animals, told MIT Technology Review. He added that a more thorough check “should have been done.”

The FDA scientists who found the problem agreed. In their report on the case, they noted that their find “highlights a potential blind spot in standard genome-editing screening methods.”

However embarrassing, the genetic insertion is unlikely to affect the cows or anyone who might end up eating them. As Sonstegard put it, they’re “safe to eat with or without the plasmid.”

But the inclusion of bacterial DNA in a cow’s genome makes the regulatory aspects of Buri and his offspring far more complicated—practically untenable. They’re not just edited, all-cow cows—they are genetically modified organisms with DNA from a completely different branch of life.

Some of the animals have already been incinerated, and regulators in Brazil have rejected plans involving the animals.

Recombinetics, meanwhile, isn’t ruminating over the blunder. It has already moved forward with gene-edited, heat-tolerant beef. The company noted that it hasn’t found any bacterial genes in those animals.
