3d not being required makes a hell a lot of sense and of course it wasn’t people have been drafting on paper for ages. They might’ve ended up on Mac or maybe Amiga, but an SGI workstation is quite an investment when you don’t even need to spin polygons. IRIS GL dates back to the early 80s, doesn’t seem so much to be a timeline but price and need thing. And it’s not like you can’t have a 3d view without acceleration, just would take a while to render and a frame every five seconds might still be usable.
There apparently was an IRIX version at one time but with no user base preference, more likely they were thinking “where’s my C: drive” so once 3d acceleration hit the mainstream everyone happily switched back to Microsoft. Meanwhile you have 3d artists complaining that they can’t move windows with meta+lmb on windows.
The watthours is what gas is for. Germany’s pipeline network alone, that’s not including actual gas storage sites, can store three months of total energy usage.
…or at least that’s the original plan, devised some 20 years ago, Fraunhofer worked it all out back then. It might be the case that banks of sodium batteries or whatnot are cheaper, but yeah lithium is probably not going to be it. Lithium’s strength is energy density, both per volume and by weight, and neither is of concern for grid storage.
That’s physically impossible for a place the size of Germany, much less Europe.
