I heard an interesting report on the BBC this morning. It appearsthat there are rock formations deep below Australia that maintain a constant temperature of 300 degrees farenheit. That is hot. There are plans to use this heat to generate steam to generate electricity for Australia. Although it is a bit more expensive than coal (I think I remember it was eight dollars more a unit or something) it could provide electricity for Australia for the next four hundred years.

I googled it but couldn’t find anything on the web on it.
