Comment on NASA’s incredible new solid-state battery pushes the boundaries of energy storage: ‘This could revolutionize air travel’

  I’m going to guess “all the precious metals in manufacturing of the EV are so much worse than my gas cars!” Nonsense that the oil industry has been shilling online with bots for years to slow adoption of EVs among specific demographics.

  Even though this myth has been debunked a hundred times, by folks like MIT, and in Reuters they showed if you live in an area that’s exclusively renewable power like I do, then I actually broke even 4ish years ago; within 3 months of owning my EV.

    I read one of the studies and they pitted a Prius vs a Leaf. Like the best possible and most efficient ICE car that is also a hybrid Vs one of the worst BEV and used it in a highway

      I wonder what they thought that Prius’s battery was made out of. Must have been gas cells or something. Couldn’t be one of those pesky rare earth batteries.

        Depending on when this “study” was done the Prius probably had a NiMH battery though.

  They are worse on the environment then gasoline cars due to the rare earth materials needed to make a EV and it is harsher on the environment when it comes to dispose a EV once they reach end of life.

  And all a EV car does is demand energy from a power plant which are either using coal or natural gas for the most part. The only “green” efficient power plant option out there is nuclear but no one wants to go nuclear.

  If your concered about the climate and want to take that into account when getting a new vehicle. I always tell people to buy a used vehicle since it already exists and by driving a used car, your keeping it from being in a land fill and you save money buying used. Or the other best option is to get a bike or use public transportation.

  And I do not see any difference with battery powered planes. I see more planes crashing due to using a new technology. Planes have come a long way and only gotten safer with years of engineering but by changing the power source to a battery over gasoline, unexpexted problems will like arise. Essentially do not fix what is not broken.

    All of that is wrong except the bike or public transportation:

    Lithium is not rare and is largely mined in areas with no life at all. The US gets most of its lithium from the Atacama Desert in spots where there has never been recorded rain. Cobalt is more rare but that is being phased out in newer batteries.

    As for emissions, an EV is better over its lifespan even if it is charging up from 100% coal energy. The breakeven point for that is about 85k miles. With your typical energy mix, it is closer to 20-30k. Even buying a used car does not win when it comes to emissions over its use unless you are planning on driving it less than 85km.

    For electric planes, they are already starting to do smaller ones with a short range. Solid state batteries will allow for much larger ones.

    Nuclear is not the most green energy source. It is significantly better than fossil fuels but it is still pretty far behind both solar and wind with energy storage.
