A recent ch4 prog visited Polperro and mentioned their sea-gate that I
was not aware of.
Looking for more technical detail, such as

I was surprised to see only an expected lifespan of 30 years ,
presumably because of extra storm damage , similar to what knocked out
the earlier one in 2014. Rather than the somewhat minimal sea level rise
in 30 years (assuming there is not sudden greening of Greenland and
Antartica that is)
