A Global Safety Case GSC for the planet to address climate change and other issues? #GlobalSafetyCase
which leaves the upland area east of the A6, that I think also has a high pressure gas pipeline running through it. Lots happening underground in that area.
I think Crookdale already has a large high pressure natural gas pipeline, a large aqueduct pipe, and a pumped treated water pipeline running through it, so I imagine it may well be impractical to cut cable trenches through it,
It the technical aspects of cables in tunnels matched those of overhead lines, I would prefer cables in tunnels under the national park, and to make the tunnels longer than the minimum needed to pass under the national park.
In the past I preferred the option of tunnels for cables under the national park, but having taken all these things, and the technical and security of electricity supply aspects into account, I have ended up preferring overhead lines, others will prefer other options.
I understand a project to remove 3km of similar overhead lines at Hale Purlieu in the New Forest, and put them underground in cables in trenches, was shelved because of concerns about the potential damage to the forest floor.
I guess different people put different priorities on protecting the national park. Protecting the visual appearance of the park, protecting the soils, the land, the rock, the ecosystems, the vegetation, protection from noise and construction activity, emissions, costs etc.
There would also need to be a special termination tower and equipment in a fenced substation structure where the overhead lines cables went underground and emerged.
From Google Maps, the cables in Somerset have around 16 cable joint chambers along the route, the green fenced items in photo at maps.app.goo.gl/87tTkqdBKVWR...

It has been done over a similar 5.3 mile distance in Somerset, but that was through a valley, not over an upland area. The cables would need to cross over Borrow Beck on a bridge or under it in a structure.
It could be done by trenching. Google makes it about 5.4 miles minimum across the National Park on the existing route 👇. A possible alternative route across the National Park via Tebay and west of the Lune Gorge is about 4.7 miles.
which is another reason I don’t favour trenches or tunnels at the current time, they could become redundant, but not possible to know if this will happen.
much easier to fix overhead lines. But like the long-gone telegraph/telephone wires and poles that would I imagine have been in your photo a hundred years and more ago, maybe HVDC transmission technology will remove the need for any lines over or cables under the Shap Fells within a hundred years,
. . . or four of these www.youtube.com/watch?v=KIET... , two north and two south of the national park for 10 years and 1000’s of CO2 generating steel reinforced concrete tunnel segments. On reflection, I prefer the in my view, less environmentally damaging, technically superior, much cheaper,

The alternative, at least two trenches of this 👇 width dug across the upland soils and blasted through the rock of the national park for up to 9km, for cables needing to be dug up and replaced maybe every 40-60 years, (photo Charlotte Webb 👏/National Grid)
Great photo of the I think highest located 90+ year old 132kV tower in England on the right, and highest located 66-year-old 400kV tower in England, their survival and reliable high voltage electricity transmission through many storms overarched by a rainbow.
@engineerlondon.bsky.social Well-designed transformer with convenient mug shelf.
The Lune Valley between Caton and Claughton were flooded right across the flood plain this morning, have not seen it like that for a while.
I agree, but have been surprised to read online, that it was originally the Victorian version of the DWP office, the Whitehaven Poor Law Union, photo at www.whitehavennews.co.uk/resources/im...

I presume, overflows via pipe in tunnel/culvert to NGR. NZ9557005290 in sea, but YW intend to improve bathing water quality at RHB as part of a £8.7bn spend by 2030, so look forward to another visit in 2030’s to take a look and check out the
From what I read, since 2000 waste water from RHB and Fylingthorpe etc. has been pumped ~4.7 miles along old railway track route to Whitby WWTW, with discharges to the sea at times of heavy rain when combined sewer overflows to King’s Beck, and/or pumping station at www.geograph.org.uk/photo/3951432

This probably pumps sewage. The gantry is no doubt for lifting out the pumps for maintenance.
