/2 #photography #construction #steels A long time ago, I was 'trade'. Contractor & ltd. company. Loved every minute. I know exactly what's occurring here. The #HenryVII visitors, study centre (bloody #Tudors!) & 'community' centre. Another tourist honeypot in the centre of #Pembroke. Squillions of £'s, now overrunning, over budget and for the benefit of whom pray tell?

Promising material for a #SpaceElevator 
: #Graphene in the form of a nearly transparent (to visible light) one #atom 
thick sheet. It is hundreds of times stronger 
than most #steels by weight https://en.wikipedia.org/wiki/Single-layer_materials#C:_graphene_and_graphyne
The invisibility 
of the two-dimensional material structure was a problem for #quality assurance, now tackled by the #Universities of #Amsterdam, #NewYork and the #Spanish National Research Council (#CSIC)
