Another fine job without physics

Reference




This was a totally political job.  "Let's place a turbine on the most vicious current-raked silt bottom we can find."  "Who needs that expensive physics?"

Suddenly it stops turning.  What sea monster is in it's jaws?  Or is it just buried in silt.  The only barge big enough is bankrupt, as well.  Even if they got the barge, I'll bet they can't pull it out of the mud.  Where are the underwater pictures?  Is the current too strong for a robot?  :)

ps.  that was my problem in the old company.  This sort of thing was my job.  I would have said "Forget it."  and then would have been blamed for being too grouchy.  :)

pps.  This is like the offshore of Pickering.  The silt moves in giant dunes, like on the Sahara.  If you just checked one thing, then you could anchor it on clean rock.  However, it's coming for you, like giant sand worms.  They'll be lucky if they even find it.

more:  Just on general geotechnical engineering.  The installation of drains and waterstops must be continually inspected.  The place will rust out in 10 years.


Another indication on why I will never work again (as if I wanted to).  I would have insisted on extra testing and a more fail-proof waterstop system, thus adding to the cost.  The Niagara Tunnel to Nowhere has no water problem, since it is flooded and sealed up.  :) It might be having a collapse problem, but we'll never know.

Thanks for the chuckles.

Ah laddie the great sucking sound will be awesome to behold. Lost a pair of rubber boots there whilst fishing in 1996. Perhaps a wee pull if they come across them as well.....

Did you see this article?

https://phys.org/news/2019-04-carbon-dioxide-highest-million-years.html

CO2 greenhouse gas levels in the atmosphere are likely higher today than ever before in the past 3 million years

How would they know that?

"a team of scientists succeeded in using a computer simulation that fits ocean floor sediment data of climate evolution over this period of time"

Oh, a computer simulation!

Changes in CO2 levels were a main driver of the ice ages

"It is a breakthrough that we can now show in computer simulations that changes in CO2 levels were a main driver of the ice ages, together with variations of how the Earth's orbits around the sun, the so-called Milankovitch cycles. These are actually not just simulations: we compared our results with the hard data from the deep sea, and they prove to be in good agreement. Our results imply a strong sensitivity of the Earth system to relatively small variations in atmospheric CO2. As fascinating as this is, it is also worrying."

Now, I'm of the opinion that the earth has had vastly higher CO2 levels previously--and it went along just fine- Just thought I'd share :)

They should just admit they don't have the resolution to tell the difference between lead and lag. It is expected that if things get really cold, then the co2 goes down due to greater storage in the oceans.
