  • Yeah that is true, but another useful application of Hydrogen is that it can store energy, like a battery. Think of it like a hydroelectric facility. You take water which is a low energy state, the bonds are super stable, you add a lot of energy to it, then it becomes Hydrogen, which is a high-energy state, very much less stable that can be used as an energy source whenever we want.

    I think this is the really important application of hydrogen, as an alternative for batteries, as most technologies for conventional batteries require a lot of rare minerals and I doubt our planet will be able to sustain a transition in renewable energy, hence a huge increase in load for our electricity grids and demand for batteries, if we only have conventional ones. And on top of all that, you have to factor the fact that the economy will continue growing exponentially(it doubles every 20 years).








  • Or better yet - this helped me more because I couldn’t get what you were saying until I saw it - is that you can think of either one of two faces that the cube can sit on. Before I explain which faces I am talking of, I have to note that a cube face can be described by its diagonal, which is what I have to do to explain this in words and the second one is that in a drawing of a cube there are six peripheral intersection points(three to the right and three to the left) and two inside points a right one and a left one. So these two faces the cube can sit on are:

    The first is the face whose diagonal starts from the bottom left peripheral point and reaches the right inside point

    Then the second face is the one that spans from the left bottom peripheral point until the right middle peripheral point.

    This helps me change perspective instantly.
