honestly robotic cranes stacking and unstacking useless concrete weights for all eternity is the surreal dieselpunk energy storage solution earth deserves https://qz.com/1355672/stacking-concrete-blocks-is-a-surprisingly-efficient-way-to-store-energy/
@vogon fantastic! This is the kind of innovation that makes me feel that the future may actually be pretty awesome.
@sixohsix @vogon Totally agreed. Maybe there's a market for this crane, maybe not, but it's definitely worth finding out. I especially suspect the flexibility of the concept - the fact it can use a variety of dense waste materials - may be worthwhile.
Sure hope a fully stacked tower of concrete blocks can hold up to strong winds, though. I'd hate to see the mess *and* loss of useful energy that would ensue if one of these went Jenga...
@tomas that, plus they take waste out of the waste stream instead of manufacturing more of it, plus the capacity doesn’t degrade over time.
@vogon If this will require us to produce more concrete, that could be a problem; because concrete production is energy-intensive and polluting.
@vogon mate it's just dry hydro
@vogon for a second i thought a competing technology was claiming 99% efficiency 🤔 😅
