It鈥檚 gone a bit quiet again, if you don鈥檛 count the rain. Work is happening at the pier, but the boys went away yesterday to do their Christmas shopping. They caught the first boat, just in case. We are getting a new sea wall. It may not be the best weather to build a sea wall, but there is so much stuff it could only be done when the ferry is quiet. The car park is full of steel cages. These are the reinforcings for the walls, great long lengths all welded and wired together. Around the seaward side of the car park is a big hole. I gather this wasn鈥檛 that straight forward; something to do with granite not being ordinary rock. Then there are the deliveries of aggregate, and these heaps have to go somewhere where there isn鈥檛 already something else. Safely up the hill at the burger van it is all very entertaining!

We had another rock driller in. He went through the granite very easily. The new green energy is geo-thermal. He drills pairs of holes straight down (in this case, two pairs, but one doubled up as a water bore-hole), and then a fancy liquid is pumped down one, up the other, through a heat pump (back to front fridge), through the pipes forming the under floor heating circuit, and then back into the ground to warm up again. Apparently one and a half metres down there is a constant temperature of 15 degrees C. Seems too good to be true. In Scotland there is a 30% grant, but it is still a lot of money, about 脗拢7000. In 50 years time, when every house has one there will probably be scare stories about the Earth鈥檚 core cooling down too fast.

PS Maverick beer on tonight.
