Working on one of the boilers at the former Didcot Power Station. This was taken at a time when I was in the habit of just 'starting the camera and leaving it running' so I hope you enjoy my super wonky vision video and the random stills at the end....! I must have lent on the 'zoom' button so in the middle there is an over zoomed in bit before I noticed and zoomed it out again. If anyone recognises anyone in the video, please feel free to comment. I was with Alan London and another chappie. At 6 minutes in, we enter a huge space filled with scaffolding - that is the INSIDE of the boiler - where the huge fires normally burn. This was filmed mainly in and around 'Unit 2' the part of the structure that collapsed about ten years after this video was made, little realizing the fate that would befall it, including loss of life when it failed in 2016 during dismantling, works after 'disastrous errors made during preparations for demolition, in what has become in terms of sheer tonnage of steel, probably the world's worst industrial disaster - RIP to those who perished in 'our building'. xx More of the collapse here... https://www.youtube.com/watch?v=IADrLnDvwuY&list=PLrJD4W-hig-cANPpPm2owlTNlu32R1iNF ... https://www.youtube.com/watch?v=3v9xRkl5kUk

Our Mk4 Meccano stirling engine, this one is a twin cylinder unit using the 'Airpot' 'free sample' piston any cylinder set. Google 'airpot' for more data. The Mk4 Stirling engine - built from Meccano, various tin cans, and two graphite pistons running inside glass cylinders, sleeved in black plastic - the 'Airpot' units. Stirling as in Stirling engine is spelt Stirling not Sterling. For the technically minded, the displacer is 6cm diameter by 2.5cm stroke, and the piston is 1.6 cm diameter by 4cm stroke. The displacer is in an air tight chamber and is moved up and down, by a thin wire passing through a seal made of silicone bathroom sealant. This moves 'displaces' a trapped volume of air from the 'hot end' heated by a tea light candle sized flame and the 'cold end' which is at room temperature and back again, this causes the air to expand and contract, pulling and pushing on the piston, driving the engine. The Flexi balance springs are made using a new type of ultra thin springy strip that Meccano new include in some of their sets. The displacers are allowed to 'land' at each end of their travel, this gives maximum performance, it also results in that lovely sound! The Video was taken in wide screen format - don't know how to get wide screen to play properly on Youtube - maybe it will sort its self out. Check out our MK5 and other engines here on Youtube. The Merry-go-round was built by the youngsters seen in the background. Coppa compliance - this is a general mixed video of interest to all ages and not made specifically for young children, especially as it involves unprotected flames and hot engine parts ... https://www.youtube.com/watch?v=5jMDRtNklMY
