Hi Cobbers and natural builders.
Below is a quote from a yahoo story in today's popular science stories
section. It has been determined that much of the pyrimids was cast and
not chiseled from limestone. Below that is a seriously long link to the
stroy. It was cut and pasted so it should work
"Why do the results of Barsoum’s research matter most today? Two words:
earth cements.
How energy intensive and/or complicated can a 4,500 year old technology
really be? The answer to both questions is not very,” Barsoum explains.
“The basic raw materials used for this early form of
concrete—limestone, lime, and diatomaceous earth—can be found virtually
anywhere in the world,” he adds. “Replicating this method of
construction would be cost effective, long lasting, and much more
environmentally friendly than the current building material of choice:
Portland cement that alone pumps roughly 6 billion tons of CO2 annually
into the atmosphere when it’s manufactured.”
“Ironically,” says Barsoum, “this study of 4,500 year old rocks is not
about the past, but about the future

Those who question global warming have a financial or emotional
interest in the status quo.
