    It’s true. Give me a hot and dense enough furnace and I’ll recycle everything into iron. EVERYTHING.

      Wouldn’t the hot part actually make it harder…? All you want is density and as little to counter gravity as possible.

            I guess to overcome electron degeneracy pressure. Nucleus would collide more easily when electrons are stripped away. Not sure if i am conpletely true though

              Heat means more vibrations, which means less density and more force needed to compress the matter to the same density. Just compare any solid material to plasma. Or the 100 million kelvin plasma at ITER, which has an absurdly low density (like a high vacuum) but still 1 bar of pressure due to the thermal pressure.

              Electron degeneracy pressure is always present when there are electrons, regardless if they are part of an atom or free moving in a plasma.

                Higher heat also means more violent collisions. It would be much harder to collide nucleus by just pressing it. But yeah maybe with even more pressure it might happen but nuclear reactions usually happen with high speed collisions.

                When electrons are bound to nucleus, it may prevent collision by having an additional layer causing degeneracy pressure between two colliding nucleus. That won’t happen if electrons are unbounded to nucleus. Atleast that’s what i imagine

                  The electron pressure is always there.

                  But you are right regarding the thermal energy making fusions easier, which can happen at any pressure or density with enough velocity. At this point I am not even sure which of the 2 approaches (cold and far denser or hot and far less dense) would be “easier”, where we would have to first define what easier would actually be…

    They’re not recyclable yet. In a few years when we have Mr. Fusions and replicators, things will be different.

      PET bottles yes, other plastic bottles not so much, or at least until someone figures out a way to turn plastic trash into a cheap alternative to petroleum.

      Not really. Plastic gets damaged when heating it up to melting temps. You won’t get a product that has the same properties, unlike with aluminium for instance. You can maybe get away with adding a small percentage of recycled pellets back in, but that’s it.

        Metals are also not 100% recyclable due to contamination. We just have plenty of use for low grade metal alloys.

          Which literally means “anything other than aerospace engineering”. Aluminium and other metals are infinitely more recyclable than plastics, which as I’ve said before, degrade immediately to being barely usable.
