  The project you referenced intends to use recycled concrete processed into the 35-ton blocks they use for energy storage because it's cheaper. They plan to stack as many as twenty of them on top of each other i.e. the bottom block will have a load of 675 tonnes pressing down on it. The foundation will have to support several thousand tonnes static load as well as the dynamic load of the crane. Like I said it looks good on paper/PowerPoint and table-top models but in real life scaled up to useful dimensions it has its problems. As for Greg's fascination...

  in real life scaled up to useful dimensions it has its problems I agree. But I was trying to point out the positives. I quite like the idea of a taller than 100m crane lifting and lowering big blocks of concrete, but the same problem as the accumulator tower applies. 35 tons seems like a lot, but we have that same mgh problem... 35000 * 10 * 100 = 3600 * 1000 * 10 = 10kWh. That makes the presentation pretty, but you're going to have an awful lot of blocks per megawatt-hour if your crane can only lift them...

  They could move Ben Nevis to somewhere in Cambridgeshire, more accessible for tourism that way too. Funny this topic sort of came back to life - driving around today it occurred to me to remember gasometers ... there were still a lot of them around Brisbane when I was a kid. So what if they were 100m tall, and each vertical frame member had a track for a worm gear... then you don’t need to be keeping gas in, just mount a lot of mass on a platform. But maybe it’s jaunt me, thinking gasometers are sort of retro-steampunk-romantic-gothic-cool or...

  Just me, that is. I think that was autocorrect, but it could be me subliminally thinking of Tomorrow’s Children and how the Laundryverse reminds me of it slightly, in terms of culture and feel and stuff. Maybe that’s just me, though :)...

  Oh, sudden thought: with the crane idea, make each block an apartment. That way every single one can be sold as a penthouse apartment! Trump would wet himself at the idea. You could do the same thing by lifting suburbs independently... they would all have "great views over surrounding area" and a whole lot more would have "sea views" :)...
