I don't see what point has risen your ire. There is a great deal of
research into the thermal characteristics of cement and concrete. Most
of it looking to lower the conductance, but the reverse is becoming
It's a remarkable building material that the ancients knew a great
deal about (the Pyramids are made out of cement). After the fall of Rome
most of this knowledge lapsed and the builders of the Renaissance were
unable to figure out how to make a decent version of this ubiquitous

Or old nuts, bolts and washers which are available cheap. Or in this case,
placed in the centre of the concrete block, Nick Pine's idea of 2 litre
plastic Coca Cola bottles filled with water.

Over time, they lose water through the walls.

Well a bad idea then. The idea is the maximise the heat retention and
conductive properties of the concrete block - as been said it is none
structural. Well maybe iron pipe with caps on the ends? :) Expensive
operation to do this so maybe lots of old nuts and bolts as ballast.
