Comment on Japanese experimental nuclear fusion reactor inaugurated

  They are, and they are good solution but they are not good all and end all solutions, both wind and solar cannot meet baseload and when you start talking about battery storage as solution, scaling it up requires more metal mining than will ever be sustainable, so pursuit of fusion, pursuit of tidal energy, pursuit of better nuclear, pursuit of better geothermal are viable exploration options as we need baseload generation substitute.

    You do not need batteries to store potential energy. You can pump water up a hill into a reservoir and then harvest the energy when you need it using hydroelectric energy.

      Dams are a whole another story ecologically but even leaving that aside, we are talking 200-300GW capacity currently in the world for PHES, even if you construct damns on every possible lakes, estimates are around 1000GW that world can build. World currently consumes close to 8000GW on baseload. We won’t even cover 15% of baseload with PHES.

      If you’re trolling with your storage as magical solution keep trolling.

        Not sure if you are being willfully obtuse, I’m going to assume good faith.

        A dam is a hydroelectric plant. you need a river a ravine and a lot more conditions to be met.

        This is what I was talking about: en.wikipedia.org/…/Pumped-storage_hydroelectricit…

        and technically speaking potential energy could be stored by lifting bolders and then harvest the released energy when they are allowed to come down. There are many ways to device systems like such. You could even go underground and use drilled wells with two reservoirs at different levels for this.

        You are mistaken to dismiss this outright without at least looking at the wiki i linked.

  Imagine making this kind of comment in a technology community.

    Imagine not explaining your position instead only using derision.

    El Barto if you are who you say you are, you will explain to us WHY the aforementioned is worthy of derision.

      Because a technology community is usually filled with people interested in advancements in technology.

      So, say, you’re interested in space telescopes, come to this community to read about the latest advancements and you’re hit with someone saying “pffftt, stick to ground telescopes, people!”

        I didn’t downvote you, by the way.

        I didn’t take you for the type to downvote me 😉
