The high temperature bit at least is iffy, if it's high temperature,
you can still make electricity.
Also, overall I just don't get what Calera precisely want to do. They
say they are producing "cement", but it's awfully vague. What exactly
are their inputs, their output and why will that work as a cement
substitute (it isn't really cement or is it???)
