Covid-19 ‘Arsenal of Health’: Automakers Are Building Ventilators, Masks

Eighty years ago, automakers called themselves the “Arsenal of Democracy” as they built bombers, tanks, and heavy trucks for World War II. Now as Ford, GM and other carmakers in the US ramp up to manufacture ventilators and even masks, they’ve been labeled the “Arsenal of Health.”

It’s possible because automakers are more than mile-long assembly lines. They also have expertise in procuring parts, they have specialized short-run assembly lines for development work, and they have 3D printers. They also have a workforce that is otherwise unoccupied since automobile manufacturing has been shut down beginning March 18. Even Tesla shut down after a short-term holdout on the part of its CEO.

In the US, 17 million motor vehicles were produced in North America last year. Ramping up production of tools for dealing with coronavirus isn’t instantaneous, so the country has been hurt by the lag between the first knowledge of coronavirus in early January and early March when life as we know it started shutting down. Early January is when US intelligence services first learned of the magnitude of problems in China and the odds of the epidemic becoming a pandemic.

General Motors says it will work with Ventec Life Systems of Washington State “as soon as April” to build 10,000 ventilators a month at an electrical components factory in Kokomo, Indiana. The plan is to produce up to 200,000 ventilators, which would mean production through the end of 2021. Separately, GM at a Warren, Michigan facility will start producing masks in early April, ramping up to 50,000 a day; GM says it could later double the number.

Ford will work with GE Healthcare to do additional production of GE ventilators, meanwhile developing a simplified ventilator design that Ford would build. Similarly, Ford will partner with 3M to build additional 3M respirators and, again, designing a simpler respirator it would build. And it is designing and tooling for face shields that could be turned out 100,000-per-week at a Michigan plant.

Tesla said it will reopen its idled Gigafactory 2 in Buffalo, NY, to produce Medtronic ventilators. The factory has been an alternate source of pride and anger upstate. The so-called Buffalo Billion, a state grant of that amount, went to create high-tech factories. Much of it went to a factory that was, in alliance with Panasonic, to build solar panels through Tesla subsidiary SolarCity. Then it was repurposed to build lithium-ion battery cells for Teslas, and Tesla had a deadline of April to show the factory was up and running, building batteries in quantity. Now, it’s being repurposed, at least for the time being, to build ventilators.

The major makers of ventilators, pre-coronavirus, have capacity to build ventilators in the hundreds of units per month. Now they’re ramping to double or quadruple production but the needs are in the tens of thousands per month. A hundred thousand units in April would still not meet the spike in demand.

Praise, Criticism, Praise From the White House

General Motors has been alternately praised and criticized by President Trump. Friday he said he was invoking the Defense Production Act to produce ventilators.  A White House statement Friday said:

Our negotiations with GM regarding its ability to supply ventilators have been productive, but our fight against the virus is too urgent to allow the give-and-take of the contracting process to continue to run its normal course. GM was wasting time. Today’s action will help ensure the quick production of ventilators that will save American lives.

Other reports have said GM already had the project in motion and that it was unclear if the president had invoked DPA before Friday. At several news conferences, reporters tried to get the president to say if he earlier had invoked DPA. At Friday’s event, the president talked in the same sentence about getting “General Motors” to make ventilators and then referring to “General Electric.” That was the point where he spoke of $2 billion in relief funds then said $2 trillion. (The Coronavirus Aid Package, or stimulus, is for $2 trillion.)

History of Repurposed Auto Factories

The automakers and Michigan media love “Arsenal of Health” because it harks back to World War II and the “Arsenal of Democracy.” In early 1942, the US ended auto production and turned to build weapons of war. One of the greatest advantages the US and the Allies held over the Axis powers was its ability to vastly outproduce armaments as well as food and clothing.

The automakers also reveled in their ability to produce complex weapons (tanks) and even more complex weapons (bombers) when the aviation industry doubted Ford, GM, and other carmakers had the skill. James Dutch Kindelberger, then-president of North American Aviation (P-51 Mustang and other planes), ridiculed the idea that mere auto factory workers at Ford’s Willow Run, Michigan, plant could build an 18-ton aircraft such as the B-24 Liberator. (A 3,000-pound car of the 1930s had about 15,000 parts. The B-24 had 450,000.)

“You can’t expect a blacksmith to make a watch overnight,” Kindelberger famously said. He was wrong. By war’s end, four genuine aircraft company factories run by Consolidated Aircraft, Douglas Aircraft, and North American Aviation turned out 9,808 Liberators, while Ford’s mile-long factory (included a turntable and 90-degree turn halfway through) built 8,465, each with four Buick-built, 1,200-hp Pratt & Whitney R-1830 Twin Wasp engines.

Now, it’s the automakers’ turn again, including the ones who got a billion-dollar bailout a decade ago.

Star Trek: Voyager Gets 4K Upscale Remaster via AI

End users are waking up to the idea that AI-based products can demonstrate practical use cases for ordinary people. About a month ago, I covered my early work upscaling Deep Space 9 for the modern era — and I’m not the only one working on this sort of project. I was inspired by the work of CaptRobau back in 2019, and now a new individual has launched a project of his own, this time to remaster Star Trek: Voyager.

Reddit user theboomsterz remastered the TV show using Topaz Gigapixel AI initially before switching to Topaz Video Enhance AI. He’s published a couple of clips to show the net effect, and it’s interesting to see them now that I’ve been working on DS9 for the past few months. One bit that theboomsterz states in his Reddit thread is that he’s run some of these episodes through the application more than once. I admit, I haven’t tried that, but there is a theoretical method for doing so — Topaz VEAI has recently added the ability to run a video file through without upscaling it, in order to remove noise and other visual artifacts. I haven’t tested the impact of running it 3-4x in a row, though.

Here’s a second clip. This clip implies that Voyager suffers from the same problem Deep Space 9 does — namely, it’s quite dark. I’ve been collaborating with a few interested readers who wanted to contribute to the Deep Space 9 project by looking for solutions to this issue.

It’s great to see more fans taking up this kind of work. ExtremeTech, again, does not condone piracy or working from downloaded torrents — if you want to perform this kind of upscaling work, you should work from the original DVD source — if only because, believe me, you’re going to want every single bit of detail you can scrape out of these DVDs. It doesn’t amount to nearly as much as you might hope.

The big question, of course, is whether these various fan efforts have a chance in hell of persuading Paramount to actually do the job itself. The answer to that is probably no. I really hate to type that, because Paramount is capable of doing some absolutely stunning work. Here’s a clip from the DS9 episode Sacrifice of Angels that Paramount remastered for the What We Left Behind DS9 documentary.

Nothing anyone is going to be able to do with source footage is going to approach this kind of fidelity, and each series of ST brings it own challenges. Voyager was apparently filmed in variable frame rate, which theboomsterz discusses as a challenging issue to deal with. I’ve been grappling with some issues myself, but I’ll drop an update on my own progress into a separate story.

Hands On With AMD’s New Radeon Pro W5500 Workstation GPU

Value-priced is not a term typically used to describe workstation GPUs that can support visualization and VR applications. Usually, 3D-focused GPUs come to market based on impressive performance claims and a price point to match. That was certainly the case with AMD’s Radeon Pro W5700 that we reviewed recently. But now the company has provided an impressive cost-reduced version, the AMD Radeon Pro W5500, at half the price ($399). We’ve been working with an early unit, and so far are quite pleased with what it can do at a price point more typical for a mid-range gaming or entry-level CAD GPU.

AMD’s Radeon Pro W5500 By The Numbers

Like the $799 Radeon Pro W5700, the W5500 is built using AMD’s 7nm “Navi” RDNA technology and features 8GB of GDDR6 memory. It can process at up to 5.35 TFLOPS (FP32) using its 22 compute units while consuming a relatively miserly 125 watts. It also offers support for PCIe Gen 4, if you have a compatible CPU like a recent Threadripper, but of course, it will work fine in a Gen 3 system.

AMD says it is 32 percent more power-efficient than the equivalent Nvidia offering, a Quadro P2200, when running SOLIDWORKS. AMD is particularly pleased with the resulting price-performance ratio it has achieved using its RDNA architecture — which results in 25 percent higher performance per clock cycle compared with GCN — and moves to a more power-efficient 7nm technology. Its relatively-low power needs mean the W5500 served with just an additional 6-pin power connector.

The AMD Radeon Pro W5500 has remarkable specs for an inexpensive card

One place where the W5500 is completely different from the W5700 is connectivity. Instead of the six mini-DisplayPort connections of the W5700, it has four DisplayPort 1.4 connections. Both configurations seem reasonable, but it does make it a little more challenging for anyone who wants to upgrade later on from a W5500 to a W5700. The W5500 can drive up to four 4K or 5K displays, or one 8K display at 60Hz.

The W5500 also supports AMD Remote Workstation Graphics support, which may be of particular interest in these days of increased working from home. It’s also VR-ready, including support for wireless VR using an HTC Vive Focus Plus. As VR-capable CAD applications increase in popularity, that is definitely a nice future-proofing feature.

Don't let the boxing gloves fool you. AMD is definitely taking the gloves off positioning the W5500 versus Nvidia's Quadro Pro 2200

Don’t let the boxing gloves fool you. AMD is definitely taking the gloves off when positioning the W5500 versus Nvidia’s Quadro Pro 2200.

As with the W5700, AMD claims its performance is ever more impressive when multi-tasking or using both the CPU and GPU. It claims as much as a 10x speedup over Nvidia’s Quadro Pro P2200 ODE when running multitasking benchmarks. The W5500’s 8GB also outshines the P2200’s 5GB. However, the P2200 is a year old, so we’d expect a Turing-based update sometime this year. As far as AMD’s own products, the W5500 a likely alternative for those who would have considered an older, 14nm, WX 5100 or entry-level WX 7100.

Impressive Application Support

AMD has done an impressive job of getting official support for the W5500, which makes sense since it is basically a lower-end version of the W5700 launched last year. The full list is too long to recite here, but they have official support from most of the favorites, including 3DS Max, Creo, blender, Maya, and so on. AMD also announced that its ProRender software now supports SOLIDWORKS Visualize 2020.

The W5500M Is on the Way for Mobile Workstations

AMD also announced the Radeon Pro W5500M mobile discrete GPU for high-end laptops and mobile workstations. It has slightly lower specs, with 4GB of graphics memory and a 10 percent lower-rated performance of 4.79 TFLOPS at FP32. Along with that comes a smaller power envelope of 85 watts. It features the same 22 compute units, and 224 Gbps memory bandwidth over a 128-bit interface. Like the desktop version, it can also drive up to four displays.

Who Should Buy a W5500?

Like the W5700, AMD doesn’t support AI development on the W5500, so you’ll need to make sure that you’re comfortable with its impressive price-performance on engineering and creative applications. If you can live with that, it’s shaping up to be an excellent product at a great price, with a generous 8GB of graphics memory. Keep in mind, though, that many design tasks are bottlenecked by the CPU, so make sure that upgrading your GPU will get you the performance you’re expecting. Note that the W5500 is taking a little longer to become widely available than AMD’s original projection of February 20th.

NASA Selects SpaceX for Lunar Gateway Cargo Missions

The Dragon 2 capsule autonomously docking at the ISS in March 2019.

NASA’s eventual goal to send crewed missions to Mars will be easier to accomplish if we can return to the moon, but it won’t just be to visit this time. NASA intends to construct a space station in orbit of the moon called the Lunar Gateway, and SpaceX has the contract to supply that station

The Gateway station is still in the very early planning stages, but its position in orbit of the moon rules out many of the launch platforms currently in use. So, it’s not terribly surprising that SpaceX would get the nod as it’s the only spaceflight operator with a flight-tested rocket capable of sending large payloads to the moon. 

SpaceX says it will use the Falcon Heavy for Lunar gateway supply runs. This rocket is essentially three Falcon 9 rockets strapped together with some extra structural reinforcement on the center module. Most companies don’t need the super-heavy lift capabilities of the Falcon Heavy, so SpaceX has only launched a few commercial missions after the initial test flight that sent the first-ever car into outer space. 

Missions to resupply the eventual Lunar Gateway station will make use of a modified Dragon capsule. This spacecraft will have more than five metric tons of cargo capacity, an upgrade over the current Dragon capsules. The unmodified Dragon can launch with six metric tons of cargo, but only to low-Earth orbit. Unlike the current Dragon capsules that remain docked at the ISS for about a week, the modified vessels sent to the Gateway will stay there for a full year. 

While SpaceX probably could use the Dragon to move astronauts to and from the Gateway, NASA is handling that part of the Artemis program on its own. The agency has spent years working on the Space Launch System (SLS) and Orion crew capsule for deep space missions. NASA expects it will need one service mission for each crewed trip to the Gateway Station. From the station, astronauts will be able to head down to the lunar surface and return to the Gateway with relative ease. 

SpaceX has its own plans for the moon. The company’s Starship rocket and Super Heavy launch platform will have enough power to send missions to Mars and beyond. SpaceX has already committed to sending Japanese billionaire Yusaku Maezawa on a lunar orbital flight in the next few years.
