In my mum's village in Cornwall there is a church where the congretation became too small to sustain the minister and the building and eventually the central organisation cut it. The difficulty for them being that the building is listed and up a narrow lane and so very difficult to convert to an office or flats etc.

I think more of that sort of thing to come.

I wonder how much of its cost base is fixed.

You need one minister and one church per congregation. In cities you can knock congregations together, sell off the buildings and invest the capital in income bearing investments.

There may be an exciting opportunity for some financially driven entryism to come in about 15 years.

Looking at the Washington State battery I think (unless my mental math has deserted me, which is always possible) that

there is approximately 15,000 MW of wind power installed in the UK. This battery pack with 20 shipping units can take 2 MW (for 4 hours for a total storage of 8 MWH). Or 10 shipping containers per MW of capacity. So about 150,000 shipping containers to take the whole output from the UK's wind fleet for 4 hours.

Sadly, I'm having difficulty visualling 150,000 shipping containers.

I feel like I ought to be able to get 5 in to my flat and my building would be five stories of these high. So we'd need 6,000 of my block of flats worth of volume. Ish. I think.

I think Dinorwig can store about 9,000 MWH. That would require 1,125 systems with 22,500 shipping containers with a volume of 405,000 cubic meters.
Are you sure about the volume of Dinorwig?

I think the most appropriate like for like comparison is between the total excavation and the volume of the containers rather than with the surge tank.

The problem with having 60 Dinorwig is that it's difficult to find somewhere to put them. I think shipping containers are probably easier to keep around the place.
