"My guess, they would need to frack to improve the area of available heat-to-water interface.

"Friends" of the Earth will be happy to blow its rocks to pieces, when it suits them. They were happy to see a large lump of Cornwall blown apart to be dumped in the sea to form the Swansea tidal mud pond.

Sorry about multiple comments....just catching up on what is an awakening unthreaded stream (good to see).

@Michael Hart: So glad to find someone else who has read and enjoyed Dune - the only Trilogy I own (for 30 years) that was actually four books! The first was by far the best and, I thought, extremely allegorical. I recall thinking that the 'Gom-jabbar' (sp? memory?), a device for inflicting pain, would be a great development if it could be re-engineered: I have this mad idea that when you go to your doctor with aches and pains you will put your hand into a 'Gom', as will the Doctor. He will then feel the pains and their locations as you do!! :-)

Just a thought: Would the water being returned from deep within the granite rocks of Cornwall be highly radioactive? (serious question).

@TinyCO2: "...remoaners are lying by pretending we can just turn around and go back to how it all was"

Precisely. I have been trying to get it across to as many as possible that there is no 'remain' option now, only 're-apply', with all that that entails. If there is another referendum and one of the options is 'remain' I do hope it's challenged in the courts and changed to 're-apply' - and suitably explained to voters.

@GC: "What will the Geothermal project do, to make the rocks "permeable enough"?" My guess, they would need to frack to improve the area of available heat-to-water interface. Would it need an FOI to discover this? And would they be constrained by the same seismic limits that Cuadrilla are facing?

This would involve Remainers campaigning in support of ALL the EU's known faults, lack of Democracy, financial incompetence, fraud, corruption, plans for expansion, European Defence Force, plans for survival without reliable power etc

Two wells will be drilled 2.8 miles (4.5km) and 1.5 miles (2.5km) into granite near Redruth, Cornwall where the temperature is up to 200C."
"Energy firm Geothermal Engineering says the key issues will be whether the rocks are permeable enough to get the water through and enough heated water can be extracted to drive the turbines.

If at 200°C those rocks are hot enough to do something useful, without using/losing more energy in heat pumps. Fracking and Geothermal should be provided the same opportunities to succeed or fail.

What will the Geothermal project do, to make the rocks "permeable enough"?

Well, he would say that, wouldn't he?

Is "Mandy Rice Davies" an accepted Legal maxim these days? Far more comprehensible than anythng in Latin.

"Michel Barnier: UK could reapply for EU membership once it is ‘a third country’ Nov 6, 2018 at 8:08 AM Mark Hodgson

Does "Third Country" have some meaning in French that has not translated very well?

Mark, that comment is helpful to Brexiteers. It demonstrates that the remoaners are lying by pretending we can just turn around and go back to how it all was. New membership of the EU would not be the same as old membership. We can't have a rerun of the first referendum, no matter how many polls C4, BBC, etc commission.
