   a "green" "100 year bridge" in norway, built mostly out of wood with some steel, collapsed after 10 years
   
   it replaced a steel bridge that stood for almost 110 years

     @Aether is hydroelectric still considered green? probably not
     
     it annoys me that a lot of "green" shit is useful tech at small scale but they always try to extend it far beyond what it's actually good for, with predictable results

     @deprecated_ii Does anything green ever work?

     @RustyCrab @teknomunk steel bad mmkay
     
     generally these people only look at up front energy costs, they don't consider the whole picture. like with cash 4 clunkers where they destroyed a bunch of functional vehicles, which represented a huge sunk energy cost in their production, to get people to... buy new "efficient" vehicles, which also took a huge amount of energy to produce. was that a net energy savings? maybe, but it was small and came at great economic cost
     
     I'm not sure wind turbines ever become net positive in energy generation, on average

     @teknomunk they actually treated the wood with creosote
     
     my wild ass guess is the engineers treated the wood members as isotropic like steel, but wood is not isotropic whether it's glulam or not

     @deprecated_ii @teknomunk why the fuck is a hunk of steel sitting in a river for 100 years not considered green?

     Funny that.

     @deprecated_ii @teknomunk What caused the bridge to fail? Splitting lamination? Un-calculated flexing?

     @Intramuros_ @teknomunk I gather these wooden structures are failing because wooden connections are failing in tension, essentially the bolts are ripping out the end of the beam
     
     it seems the engineers are using retarded lab-based models for their calculations and they don't match up well with reality
