Ep 127 Mini Failure 41 Eigiau and Coedty Dam Failures

We’re releasing episodes from our mini failure library while we’re on production hiatus. This week’s Mini Failure is about the Artemis Project. It’s not really about a failure, but as our last mini failure before our hiatus, we wanted to talk about an engineering project we thought was interesting. The artemis project is aiming to put people back on the moon.

We’re releasing episodes from our mini failure library while we’re on production hiatus. This week’s Mini Failure is about the hydrogen embrittlement failure of the Bay Bridge between San Francisco and Oakland. Almost 100 rods were at risk of failure, after a construction delay and lack of protection subjected the rods to standing water and weakened them to the point that a third failed.
