Life without physics - hot dry rock geothermal


Have fun watching this as something that cannot work.  I've been looking at this for years, and I have to assume they are in the granitic basement.  The fundamental physics problem is that although the rocks are hot (temperature), there is no heat energy because of the low specific heat.  Then add the problem of low heat conduction.

They still have to drill larger holes for injection and withdrawal.  They will attempt to frack the rock and join the holes, which is a big risk.  The final nail is the high mineral content of the rock, which will quickly clog the cracks.  They might even get earthquakes when they frack the rock.

Most people have given up on this.  I'm glad Trudeau is happy....

ps.  they will find they cannot introduce horizontal fractures in that rock, but that's for another day...
