    I wonder if the increasing scarcity of usable rare earth metals would ever lead to videogame makers/publishers/etc to go strictly software, like how sega used to have the genesis, but now make their games for different consoles and pc.

    Could you imagine a world where you could play playstation, xbox, and Nintendo games on pc without emulation?

    Thorium is the low level radioactive element that is always mixed with rare earth elements.  How dangerous is Thorium?  Unlike uranium, it's not water soluble.  It has a 14 billion year half life, which means it's hardly radioactive at all!  And back in the 60's, it was discovered that you could use it as a fertile element for a molten salt reactor. By going to a liquid reactor, we can to burn up 99% of the fuel unlike solid fueled reactors that can only burn up a few percent.  Most of the waste of existing reactors is unspent fuel.  Yes! This is the key to solving our need for rare earths and our need for clean energy.  Look up Molten Salt Reactor or LFTR (Liquid Fluoride Thorium Reactor).

      I worked in the industry (state side) for 5 years, California mine is closed, filed bankruptcy a few months ago. China is still a huge (largest by far) source of REE; they still have horrible horrible environmental problems regarding the purification and mining of rare earths. Its bad, Hank's message was not hyperbole, it really is that bad over there. As for the US looking into cleaner refineries... hahahaha! Hell no! No money in going green when china sells the metals lower than what it costs them to make it. Only way US would open up these refineries is if we went to war with China and there was a shortage of REE. If someone is telling you different, they're lying to you, they don't have the investors to open up these cleaner refineries state side, you can't sell a product when it costs 5 -10x more to produce it here (the green way).

    Woa woa woa there, catalytic converters contain platinum palladium and rhodium which act as catalysts to reduce primarily nitrous oxides to nitrogen and oxygen. Platinum Palladium and Rhodium are rare earth metals but are not part of the lanthanides. So unless someone can give me information regarding the use of lanthanides in catalytic converters this video got some serious information incorrect.

    • ppp1111ppp
      ppp1111ppp 9 months ago

      Pt, Pd and Rh are not rare earths, they're PGM metals, the most common rare earth in catalytic converters is cerium. Pt, Pd, and Rh are still present but Ce, is a cheaper alternative and with its addition the more expensive PGM metals can be spared.

    From the chemistry books I've read, this is why they're called "rare." They are actually fairly abundant in Earth's crust, but are very difficult to produce in pure form. That's because they tend to occur together in the same ores, and they all have similar chemical properties, which makes them difficult to separate.

  • YEdwardP
    YEdwardP 11 months ago

    I'm a biologist, not a chemist, but what this really says to me is that there is probably a huge amount of money to be made on a patent for a cleaner method of refining rare earth elements. Because as you mentioned, almost everyone has access to these rare earth metals, but no one wants to deal with the refining.

    • ppp1111ppp
      ppp1111ppp 9 months ago

      Clean ways of refining RE exist. China doesn't give a shit, cheaper to pollute. Costs way to much to mine, process, and refine cleanly compared to what china is selling the material.

  • koolkitty8989

    I wonder how much research is being done on economically profitable things to use the waste for ... you know, rather than treating it as garbage. (most /garbage/ is valuable stuff if you know what to do with it ... coal tar and large fractions of petroleum started out as industrial waste until we realized how friggen' useful most of that stuff is ... and before THAT, petroleum itself was just treated as waste/undesirable muck you sometimes ran into when trying to dig wells for water)

    Come on humanity ... dig into that scavenger heritage of yours and find something useful to do with all that waste!


    ^same goes for nuclear waste ... except we already /do/ have ways to use most of it (reprocess and breed it into more fuel) ... we just don't because stupid politics. (similar stupid politics that treats /useful refined nuclear fuel/ AS /waste/ and melts it into glass to be burried at the Yucca Mountain depository site ... ) The much smaller fraction of waste products in more ... technical question still is the legit fission products and highly irradiated moderants (including liquid soidum/potassium) and containment/shielding material and such. (some of which we already do have uses for, others not yet, but there's not all that much incentive to put masses of industrial research into the stuff, and even FRANCE -the only country to have ever had a successful, standardized national nuclear power operation- doesn't even use breeder reactors, so produces a far, far higher waste to fuel ratio than is necessary for technology of the last ... 50 years)

    And I say industrial but ... a 100% government monopolized, standardized, non-outsourced nuclear program is probably best and ... is what the US should have done back in the 40s when starting up its nuclear power program. (we'd probably have an even better safety record than France in that case ... using similar or better standardization and technology -France uses licensed American reactor tech- on a larger scale with much more low-population locations to set up very large industrial centers fed off nuclear power -the US has tons and tons of desert regions not good for humans and not particuarly valued as wildlife refuges either ... and we already DID do all that nuclear testing in Nevada, and some in New Mexico, as it is ... so if you want double ... triple ... quadruple ... or ... whatever levels of foolproof locations and failsafes for avoiding human/environmental disasters and limiting the potential of any possible failures, there's your best bet) Using private industry to handle nuclear power generation was just a really, really bad idea. (especially in the way it was done ... it would have been OK with extremely tight government mandated standardization, but straight up government monopoly on nuclear power makes so much more sense, especially as a strategic political/military asset and in ensuring security of that asset)

    Granted ... they'd need proper funding allocated to keep all that sensible, which we HAD up until the 1980s at least before taxes got slashed. (lump it into military spending during the cold war as part of the build up -nuclear power is a MASSIVE boon for peace AND military purposes ... and then when military spending slows down after the end of the Cold War, you have that much more money to apply to civil/social programs ... so long as you don't cripple funding by slashing the upper tax brackets away)

    Disposal of all waste can be done with plasma, which turns all elements into hot gasses, which could then be separated through various processes, and used.
    There are 'plasma gasification' plants in the world as examples.
    The trick is the unstable nuclear material that could explode, but I am sure we can manage that with some development, just by building the facility so it can process small amounts of it and use the energy and material output from the reactions.

    Radioactive? Doesn't thorium tend to show up a lot with rare earth metals? Why not extract it and build some reactors to use it (especially since modern designs (such as the LFTR) are far better than the older ones).

    If radiation is just s form of energy you could have some way to collect it or use it to boil water to move turbines to get energy, so to sum it up 1.nuclear fusion/fission 2. Collect radioactive material 3. Use the heat from the radiation to boil water to turn a turbine to generate electricity. Since radiation doesn't simply disappear and it takes decades it could be very powerfully or abundant on earth/ soon to be Mars. Make this happen kids could come up with this your scientists make this happen.

  • Ikemi Zyn

    So you think catalytic converters actually do something good? I'm sorry to say they are useless and more harmful to the environment. Yes the parts per million is lower, but it's parts per million. I can take out the catalytic converter and add a fan to blowing air into the exhaust to make a lower parts per million.

    If we were to look at the total pollutants produced, you'd be shocked to find there is no difference then if we just used our fancy fuel injectors to get the correct combination of oxygen to gasoline. Yes there would be higher "parts per million" but the pollutants created would be the same if not lower.

    All a catalytic converter is, is a fancy blower that burns excess fuel that car companies make sure reaches it, otherwise it will burn out. Yes, we have lower gas mileage and burn more gas because of these catalytic converters. But hey, the world is ran mostly by oil companies, and it's good for business.

    • Ikemi Zyn
      Ikemi Zyn 9 months ago

      And that's why you have sensors and a program that compensates for the real world conditions. Vehicles have been made that did this already. They have been snuffed out by the super powerful oil companies. Those that can't be bought, mysteriously pass away before their tech is passed on.

      Also, no you can't burn gas with a %100 conversion even with modern technology. But you can come close. There would be a little bit of pollution because of impurities in the fuel. Catalytic converters can't compensate at all for these impurities. Modern tech would be able to even better.


    • ppp1111ppp
      ppp1111ppp 9 months ago

      I don't disagree that fuel can be burned to a 100% conversion with modern technology, but keep in mind that modern fuel injectors in the best engines will become dirty overtime. Even the most well maintained vehicle will loose combustion efficiency overtime. So what then? Remember that cars and trucks operate in real world conditions with changing variables, temperature, altitude, air quality, etc. all of these can affect the combustion of fuel. Your outdated technology is in your car to help compensate.


    • Ikemi Zyn
      Ikemi Zyn 9 months ago

      +ppp1111ppp Lol, buddy, with modern day fuel injectors and a couple of sensors we could just burn it as cleanly as possible in the first place instead of trying to burn it in a catalytic converter which causes more fuel consumption of a non-renewable resource, and an overall of more pollution because we burn more. People just delude themselves into believing in an outdated technology that can easily be replaced.


    • ppp1111ppp
      ppp1111ppp 9 months ago

      Lol, buddy, look up how catalytic converters work, a lot of science goes into it to help reduce toxic emissions like NOx and CO.
