Also heat cycles are supposed to soften Mg. Air cooled Beetle engine blocks are Mg. While rebuildable, a rebuilt block can't get as much usage before the main bearing journals lose roundness and alignment. To your point, VW was supposed to have applied some sort of protective coating to the blocks. I think it was yellow. I never saw it in person meaning it may have worn off after decades. Those blocks tend to cover themselves in oil for self preservation from corrosion.

[@nicolashuffman4312]

About 15 years ago, I read a report on vehicle light weighting by Lotus. They said that the economic value of removing 1lb from a car was about $3. At the time, removing 1lb from a commercial aircraft was $1,000 and removing 1lb from a satellite was $10,000. So there is not a huge economic driver for the automakers to use light weight design. Some of them realized that light weight is key to vehicle performance though, and that made light weight design more valuable. The Mazda RX-7 (FD) had all aluminum bodywork. Some Miatas and WRXs have aluminum hoods to help move the center of gravity rearward. An important design concept that I think is too often ignored is that low density materials can often result in lighter, yet stiffer structures. Stiffness of a section of material is a function of its thickness raised to the third power. So for a given mass of structural material, the lower density one can be thicker and will make the stiffest structure-- assuming you can actually fabricate the material into that structure. Magnesium rivals carbon fiber in density, so I see some applications where a low density metallic construction may be an advantage over the composite construction. One nice example of this is XTR mountain bike brake calipers. A cast magnesium caliper must be far easier to produce than a composite one would be.

Solar is NOT the cheapest energy ever produced! Typically, the cost of mining, manufacturing, transportation of solar panels is never completely accounted for. Additionally, subsidies are not considered when calculating the cost, nor is depreciation or degradation that begins on day 1. Efficiency of the panels is based on perfect atmosphere devoid of weather and pollution, and latitude is never considered. Putting industrial solar arrays in the best locations typically costs too much due to power transmission losses. Industrial solar both grossly under produces power when needed and over produces power when not needed. There is no general economical way to store sufficient power in the foreseeable future. Solar panels do work on site in off-grid applications, but so far are dismal failures in large scale applications. Modern nuclear plant designs are the foreseeable future of grid energy, especially modular molten salt designs that are demonstrably failsafe.

[@casandraa.9837]

But solar is safer and cleaner than nuclear. The storage solutions hopefully will improve. In large scale solar plants, the investment pays for itself in a matter of three years, though.

[@peterm.eggers520]

@@casandraa.9837 That is what they want you to think. Though few want to live next door to the traditional light water reactor that was originally developed for nuclear powered submarines, they are still statistically the safest of all current grid power solutions. Molten salt reactors are even safer because they can't blow-up or meltdown. Search on thorium reactors. As far as clean energy goes, research the mining and manufacturing of solar panels. You have to dig as that part is heavily censored. Also, solar panels have a relatively short life and cannot be recycled. Checkout early California solar farms that are gathering dust as the landfill costs are too high. The modern molten salt reactors being worked on now will be even cheaper than solar as once a design is perfected, they will be mass produced in currently idle shipyards.

[@SizeMichael]

How could they not be accounted for? The panel manufacturer isn't selling them at a loss, nor is the distributor taking a loss, nor is the installer deploying them at a loss. Just check rooftop solar prices at your local installers, and calculate your LCOE over 30 years. You can even put a 30% discount on their claims of energy production. You'll find that the LCOE is not only lower than grid electricity, but also lower than the grid fees The USA may be an outlier in this sense, as their extreme overregulation makes rooftop solar about 3-4 times more expensive than in other developed countries, but commercial and utility solar in the US does not suffer from this California already covers 25-30% of its evening peak power demand with batteries, charged from solar, about 6-7GW, and companies are already molding their processes to be able to use the solar power in instantaneous consumption, making batteries unnecessary This isn't something new, either. Arc furnaces have been designed to run on off-peak power for a century, just that the off-peak has moved from night to day The 2nd European solar boom is happening without subsidies

[@peterm.eggers520]

@@SizeMichael Apparently, you are not aware of the abundant solar subsidies across the US, nor accounting for power degradation from day 1, weather failures, large transmission losses from grid solar farms, habitat losses, nor end-of-life disposal costs. You also don't seem to comprehend that solar power is not constant or reliable, requiring traditional power plants to be available to provide up to 100% of the power when solar power is not available. Powering-up a backup powerplant is neither quick or without substantial cost just to start providing power to the grid. And, don't forget the investment cost of just having a full-size backup powerplant sitting idle. We are closer to fusion power after over 50 years of intense research, than being able to economically solve the grid storage for solar power. Solar power works well for most off-grid applications, and nearly all mobile applications, though storage will be the most expensive part and capacity is limited by money to invest in solar. Except for off-grid and mobile applications, solar is a waste supported by huge amounts of taxpayer dollars funneled through a multitude of programs and schemes. Modular molten salt reactors, particularly thorium based, are the only viable future for grid energy.

Magnesium in automotive isn't new, infact it's quite old. Even old alloys were implemented as engine blocks. Now saying corrosion is "solved" is a misnomer. In comparison to aluminum, the best alloy of magnesium is still quite reactive. The challenge is more on the design side. Metallurgy can still be improved, but the impact is where and how you use each metal in a vehicle. That's not to say the increasing demand for lightweithting isn't a new shift in industry. Indeed, new developments in casting techniques and Metallurgy will allow the implementation in good designs. I can easilly agree with your assessment of production. However, I think alot of people forget the importance of market circularity in emerging demand. Good design and Metallurgy should consider the requirements of recycling for recovering already extracted materials.

Making fun of US ✓ Magnesium ✓ Dow's process ✓ Few things that might need to be mentioned here: Magnesium alloys can be thixomolded - injection molding using semi-liquid magnesium, gives you better part quality and uses less energy. Magnesium alloys have very good noise and vibration dampening properties, which would make cars not only lighter (Mg vs Al ~30% lighter) but quieter. Mg is also 2% of earth's crust (Al 8%), so it will likely drop to similar cost per kg as aluminium or even lower since it's extraction can be easier and cheaper, which means it will be a lot cheaper in cars, since you'll only need around 70% of material for the same strength and rigidity. It's nice to see new alloys being actually resistant - first bikes, wheels and frames made of magnesium were extremely prone to cracking. As for weight/regulators bit - it's not true that manufacturers just didn't care about making cars lighter, but because ICE's are very limited in their efficiency and design, weight wasn't really a serious issue. If you calculate how much rolling resistance (from weight) a normal ICE has, you'll be astonished it's almost nothing in average driving conditions. You also can't go nuclear on aerodynamics like in EV, since your engine bay and tons of components will still need extremely good cooling. Mg/Alu components just aren't necessary for normal ICE cars, since there is very little to gain there. For EV's it's different story - you lose 200 kg, you can add 200 kg of batteries with no net gain. Things like thixomolding are just a really good side effect of this evolution. Also EVs are getting cheaper to produce than ICEVs, and cars are mostly competing on price.

[@willernst2721]

I worked in magnesium diecasting years back now. Yes, you can get magnesium less flammable, less being the key word. There are a lot of problems with doing that through. Mostly, the more aluminum you add the harder it gets to work with the alloy in a manufacturing sense. The alloys tend to be thicker and sticky which clogs the pumps needed in the diecast process. There is also the problem of the metals properties in general. It is stronger then aluminum but more brittle. That is how we ended up with some newer alloy as the part we were making couldn't survive crash tests without shattering, (no, i am not going to get sued for telling you any information on the actual part and really you don't want to know anyway). So we were made to use a different alloy that was so much harder to work with. Although less flammable once it was on fire it was still burning magnesium and all of the fun that goes along with that. The amount of dross in the molten metal was ridiculous and no one wants to be the guy standing on top of a 500 gallon pot of molten magnesium dipping out dross while their boots melt. The alloy was sticky and clogged every pump it went through. It also would stick to the die and cause buildup on the die that continually stopped production. Basically what i am saying is it is a really great metal that will probably never actually be used the way this video is suggesting. The finished products would be great but making them in mass is the problem, you can make a few a day real easy, it's mass production that i don't see being worked out. As for high pressure diecasting with magnesium, well almost no one does magnesium diecasting in the U.S. because the normal process so very dangerous, now make sure that explosive metal you are working with is put under intense pressure and things can go bad real quick. Had a press malfunction on my day off, die closed way over pressure and that caused water to get through into the die during a shot. This was a small part 1 and a half pound pour. The ram shot and a fireball hit the ceiling and blew under all of the gaurds, operator ended up with only very light burns. The explosion blew a hole through the die face the was the size of a silver dollar and it did it instantly, (when i say blew i really mean melted). Not sure if anyone out there knows about diecasting and tooling steel but we are talking about almost the hardest steel on the planet, makes iron feel light when you pick it up. Now imagine a malfunction when casting a 500 pound frame... Maybe i'm wrong and they can make it all safe which would be a very good thing, as for myself, i don't work in diecasting anymore because that is dangerous work.

[@themogget8808]

As far as I know, the process will be thixomolding in the case of IDRA. The dangers you describe are why traditional high pressure die casting this stuff would be a mistake. Thixomolding helps a little because less of the process exposes the metal to air, because the partially molten metal is not as hot and less of it is hot at once, and the piston pump injection supposedly solved the pump-clogging thing. Its also more automated, putting fewer workers in harm's way. And even then there are challenges that might not be solvable.

[@willernst2721]

@@themogget8808 being exposed to air is far from the worst problem, it is being exposed to the water that you need in the process to cool the doe down that is the big problem. You have to have water pumping through your die to cool certain parts while leaving other parts hotter so the metal flows properly across the die face. Under normal operation this is fine since the water is flowing inside the die and never comes in contact with the surface of the die, but stuff goes wrong and you can find videos of water and meg meeting here on KZbin. If there was a issue under high pressure while casting a large part then there is a good chance automation is going to be helpful as your whole factory is gonna be gone.

So if your process involves water, like liquid penetrant, you have to dry it really fast after washing or risk it corroding. Durring humid seasons, we have to take extra care to make sure the material doesn't corrode from sitting before or after processing. I wonder why the corrosion resistant magnesium isn't utilized? Maybe NDT has to be performed before treatment that makes the magnesium corrosion resistant? Or maybe corrosion resistant magnesium is more expensive to produce? I don't know very much from the manufacturing side since I only work in NDT.

"Back in the 90s nobody cared" Oh we did, but we were children. So all we could do was just hate the fact that our parents were doing nothing and leaving it all for us. Mostly we just hoped we would be dead before this became a problem because we knew how hopelessly impossible this would all become.

Everything should weigh alot less, heavy is junk, here buy junk. Except the engine, it should be 7% LiFe 500 8090. My car's engine magnetizes and then it warps, but will the customer pay that butt lode? How can they enjoy payments?

[@ericlotze7724]

I agree with the feeling, but from a data perspective, granted *citation needed* obviously, (Animal) Agriculture is more to blame than Housing itself. Especially growing water intensive crops for CAFOs and such.

[@SizeMichael]

It's true that the concerns of scarcity are only a thing because of agriculture, I just find it funny how many people will move from a water rich part of the country to a water poor one, and then act like water availability is suddenly an issue for the country as a whole

[@LloydLynx]

We don't have aluminum cars because of the stiff brittleness. Hit a bump too hard or get in a fender bender and you could have a giant crack spread from one end of the frame to the other. Also aluminum is way harder to weld. I have similar concerns for magnesium.

[@mikecrabtree8200]

One needs to be EXTREMELY CAREFUL with magnesium. It will burn and when it does it goes off like a small sun. Red hot Liquid Metal flows almost like water setting anything flammable on fire as it goes. If you’ve never seen magnesium light up and burn. I’d recommend looking in to some videos to see what it’s like. True enough, magnesium is strong and lite. But will roast you and not think twice about doing it if it has the opportunity.

[@unknown-ql1fk]

Magnesium cars in the north east are a TERRIBLE IDEA. It literally falls apart when mixed metals are used and in salted roads. Dont make these cars from magnesium, and the 'not burning' is a misnomer, the alloyes do burn, just at SLIGHTLY higher temperatures that would be exposed in a fire

[@ericlotze7724]

Minerals from Desalination Brine is a concept i LOVE so it is really neat to see it covered on KZbin! Sodium-Ion Batteries, Chlorine Chemicals, and even all sorts of minerals albeit a bit further further down the concentration list are all things that can be made from this route!

[@JedPotts-jv2ux]

its possible to extract dozens of useful elements from seawater, but it requires a complicated step by step batch process involving progressively smaller RO membranes, and nobody wants to risk all that investment to develop it when artificial protein based selective ion channels are less than a century away, and they'll enable those elements to be extracted at 1/1000th the cost. selective ion channel proteins already exist in your own body, your cells can distinguish between calcium, sodium, chloride, iodine, and a bunch of other ions that are used in biological processes. the hard part is figuring out how to take them from the lab to the refinery. as for magnesium itself, chlorophyll relies upon magnesium ions, so if someone can figure out how plants put that magnesium there, they can create a repeatable process that uses plant chlorophyll proteins like a sponge to soak up magnesium from seawater, release it with a chemical wash, and repeat the cycle. alternatively there may be a protein in tree roots that selectively absorbs magnesium. and all that is assuming we don't crack nuclear fusion in the next century, which would make "inductively coupled plasma ion seperation" viable and create a zero-waste source for every element present in almost any kind of water. in the far future we'll be using plants to extract metals, Pycnandra acuminata can already extract useful quantities of nickel from soil, bioaccumulating nickel citrate into its sap, up to concentrations around 25% by dry mass. plants that can do this are called "hyperaccumulators" and its a very interesting emerging field of study.

[@PRH123]

Where i grew up in michigan, Dow has been doing it for over a century. They started out with making things like chlorine, aspirin, magnesium, and later hundreds of other things. Still driving around michigan in the country you can see what look like oil wells bobbing up and down, but they are actually pumping brine from underground water that was trapped there in Mississippian age. They even pump it up and use it to salt the roads in the winter.

[@ducatista1098s]

I think stamped aluminum has unfavorable fatigue characteristics.

[@lephtovermeet]

They never adopted stamped aluminum structural components due to tan-delta aka springiness. Many steel varieties are amazingly spring (like spring steel, piano wire, and... you know, springs). This is incredibly valuable for things like spring leafs and vibration durability. Ever notice how there are no aluminum springs? I wonder if there are modern magnesium alloys that have a high tan delta. Also I bet someone is going to chime in about some specific NASA aerospace aluminum with a crazy tan-delta - I'd love to learn more but afaik none of the common readily available, easy to work with, aluminum variants have great tan-delta values - better at crumpling than springing back.

High end electric unicycles have been starting to build the frame out of magnesium alloys to reduce weight

Just imagine lithium fires and magnesium. Lol😂

[@docwatson1134]

Those unicycles are awesome. The lighter weight is needed because people daily pick them up to carry inside.

[@garrenosborne9623]

A great comprehensive insight into this metal, thanks. Just discovered your channel, am curious about your opinion on the "minerals crisis" of the green transition { & business as usual for that matter} & what do you think of Simon P Michaux's work on this?

Magnesium structurally weaker material. It is price for the light weight... Soon all shit will be maken from magnesium and be not bio, but degradable as fuck...😢

[@tiomoidofangle102]

Why magnesium rather than titanium? Asking or a friend.

Titanium is very expensive to work on.

[@Bloated_Tony_Danza]

Look into an alloy called MagThor. It was magnesium-thorium alloy and it had very impressive mechanical properties. They dont make it anymore because any addition of thorium makes any alloy radioactive, but still it's pretty cool

[@JasonDoege]

I will go to my grave with the assertion that the Volkswagen beetle was one of the most well engineered vehicles almost 80 years ago. Yup, it had a magnesium engine block as just one of the many advanced techniques employed in its design and construction.

[@Blackout00745]

Wow, really didn't thought of magnesium as a structural material... very interesting

[@dennisyoung4631]

*Lovely Magnesium!*

[@michietn5391]

While following troubles of B Bonner's ranch high in Andes, alternate land use idea: hi-altitude desert, near equatorial Pacific coast, high solar radiation, sea water not very distant, but much lower elevation. Speculate turbine pumping ocean up to solar farm, processing there, purified water goes back to low elevation recovering potential energy with turbines, then use fresh water in agriculture etc. Or, transmit high-amperage power down to coast for water processing.

[@r.t4729]

Magnesium is not new and has been used and is being phased out in Aerospace. Cost is higher because there isn't alot of finish houses thst handle it. Problems are milling aren't as easy as aluminum, cost is higher, wear a d fatigue characteristics are worse than aluminum (look at allispn 2000-2010 transfer case wear issues), and coatings have a hard time adhering and baked on csnt be used in a lot of cases becuase of lower tempering temps of magnesium. Personally I don't think it's coming back this is once again an industry not learning from the past thinking they've reinvented the wheel (which were also magnesium on VWs) when they're sifting through the garbage heap of others ideas and I don't think this time it's another man's treasure.

[@DerSolinski]

Great video... but why the Cyber truck when it's most notable feature if the "stainless"* steel. *Warranty void if you use a standard car wash

Car manufacturing is incredibly ˋcheap´. They will not pay 5 or ten times more for a lighter alloy to save a few kg. It will stay in the luxury class another decade I would guess

[@brycelunceford6549]

You skipped over the fact that a waste product from the reaction is chlorine gas. I’m assuming that’s intentional. My question is this: why is chlorine gas at scale not a huge environmental issue?

[@silaskuemmerle2505]

Well, I'd assume it could be sold to chemical companies or reacted on site to create other useful chemicals instead of simply being vented.

[@volentimeh]

Chlorine gas at scale isn't a huge issue for the same reason that every municipal swimming pool isn't a superfund site, it's only toxic in concentration, "the solution to pollution is dilution" applies readily to chlorine.

[@setoman1]

I have yet to come across any magnesium in the wild. I have ZK50A stock at home, but that doesn’t count.

[@Splomf]

I was convinced that magnesium had become a more available material recently. Especially in the manufacturing of small and sometimes complex parts. There are a few gaming mice that are made of magnesium now. At least 5 that have been released so far and a 6th that should come out soon. I knew something had to have changed for so many to have come out so quickly.

[@hypercomms2001]

If they can extract magnesium from seawater, then that means it is possible to extract uranium also from seawater, although with a different process...

[@Lore-mc7zw]

is this why I can't find magnesium sulphate anymore?

[@dubsar]

Oh, no! Scientists seem to have found a link between oxygen production on Earth and the metallic nodules found on the bottom of the oceans.

[@bazwell6735]

Your whole premise is based on the theory that autonomy will remain an issue with electric cars. There are other simpler and cheaper options. Batteries could be made to be hot swappable so instead of recharging over the course of an hour, a robot could swap the depleted battery for a charged one in a matter of minutes. Alternatively, fuel cell technology is already available and, while there's still work to be done on that technology and the hydrogen distribution network isn't developped.

[@adrianwilson7536]

So the bit about alloys that don't burn has a few flaws that I see. One is the best is removed as soon as the left sample starts to burn but you see a reaction going on the right. That's not what will happen in a battery fire so what happens if you keep the torch on it. Also that's a nice dry box but but what happens in a damp environment? Plus there isn't anything showing that alloy can be injection molded, rarely can you alter a alloy for one characteristic without altering others. Thermal mass argument is a joke as a battery pack can burn like a hundred torches for hours and not minutes, with little fire dept can do once they show up but pump huge amounts of water on it and try to stay out of the toxic smoke. Adding burning molten metal that explodes and splatters will not make them fans.

Auto makers have always cared about weight. But until now its always been a cost issue. Aluminum and Mag are just more expensive, and mag is/was harder to work with. Using those mats made the cars to expensive. But now use Americans, well other americans not me, voted in morons that force new regs and standards on auto makers. So in turn the makers are forced to use these exotic mata no matter the cost of the end car because they have to. We Americans then complain about the price of the car, so gov gives out credits, paid for with taxes that raise that we then complain about ect ect

[@Zane-It]

The reason for the American cities in deserts goes all the way back to precolombian america. Phoenix AZ was given it's name when they discovered a ruin of an ancient city under the construction of the first buildings in the area.

[@adrianwilson7536]

How does the material behave in a crash? Steel has the benefit of deforming and came be designed to corporate where the energy of that deformation goes. Aluminum cracks and shatters so you likely won't get rid of steel around the passengers. Will replacing more of the structure end up causing more vehicles to be totaled in accidents because of potential hidden damage or inability to repair?

[@Saleemsan]

I live about one freedom unit (1.6km) from the R.O. plant in SoCal. It's fine, I surfed there a lot and they raise mussels to eat. It used to be an energy plant which burned kerosene, but they put solar & wind in the east county, reversed the polarity, and now I get mussels, waves and magnesium. And water.

Al is far more brittle than steel and the work-hardening is more prone to failure. I presume this is why the methods used for steel don't work. You can use extrusions with a regular form that aren't repetitiously stressed, but nothing like how a steel frame is used
