@raymierussell @Havoc_online @ChrisMayLA6 We are building ~10GW of extra transmission across the England/Scotland B6 order (and B2) and I doubt that we'd have built all of that equivalent (allowing for capacity factor) wind in England by now, though it was cowardly short-termism to block what would have happened. And at this rate any interconnections to (say) Iceland or the US are likely to have to land in England!

@jtb @stagerabbit @ahltorp @davep @signalapp Banks and others regularly call me up and ask me to identify myself to them, ie give the unknown caller my credentials. And cannot see the problem in training their customers to comply.

@smallsolar I have semi-stealth for my off-grid system with PV on the porch roof and garden walls, as well as the non-stealth grid-connected system!

@gsc @stagerabbit @jtb @ahltorp @davep @signalapp I have left one* of the banks in question and filed complaints every single day it took to leave with all my savings. I didn't have the spoons at the time to take it up with the regulators (financial and data), but I have been director/CTO of a regulated fintech, so I am fairly confident that I could get my complaint heard if I could devote 6 months of my time... *It's complicated.

@coldclimate I was sorely temped when in my pomp and working in the City and needing to wear suits and ironed shirts to outsource at least the washing and ironing shirts part given a local bespoke service ... but decided that it really wasn't worth the price ... and non-iron shirts became a thing! %-P
