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

  I never really understood why battery technology was so difficult until a friend put it in perspective for me. The only difference between a battery and a bomb is the rate they release their energy. Now I understand.

  I read this a bit ago. Hopefully all this tech eventually finds it way into aircraft.

  My money “hope” is actually on smaller solid state batteries than can be recharged through the air. Similar to watt up tech and ossia.

  With power over air you need less battery storage and work on keeping the battery from dropping.

  Also I think best case scenario would be a massive reduction in the amount of planes flying.

  High speed rail would be a better solution. Planes across seas and then rail travel on land.

  If trains can get within speeds of air travel then we might be getting there.

  Alas will be long dead before anything happens

    power over air? 🤨

  Thanks for sharing. I struggle with feeling such dread about the climate crisis. It’s very helpful to see posts with positive stories like this. Such exciting possibilities for reducing fossil fuel usage and still having regular air travel.

  Powering a plane with a battery sounds like a bad idea. Almost worst than EVs.

    Oh yeah, way worse than filling planes with thousands of gallons of extremely flammable jet fuel

    Why do you think EVs are a bad idea?

      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.

      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.

    Did you read the article? Solid state batteries are much safer than lithium ion batteries when damaged, so the risk of fire is quite different.

    The only other reason it’s a “bad idea” is energy density, and the article is reporting advancements there. Really, just read the article next time.

      Of course they didn’t. They can’t even be bothered to provide links to research that backs up the claims they’re making in this thread.
