(57) The subject invention combines two
long-established technologies – cement
kilning and solar radiation concentra-
tion – to create a new process to kiln
cements that will significantly reduce
the non-renewable energy consump-
tion and pollution and CO2 generation of
current cement kilning methods. The
process entails using focused solar
radiation to heat closed containers
containing cement raw materials to kiln
the raw materials to produce cement,
including Portland cement.
