So what I"m getting from that little graph there is that I can store heat in thermal tanks (like I had planned) but the best thermal fluid that's easily usable is probably going to be a salt brine, right?

Unfortunately, that means I'll have to custom fabricate the tanks so that they're resistant to salt corrosion...

I'm going to have to take some time out and read those papers soon, before I even start digging my plot out. I'm planning to start digging on the nicer days of winter, because it's all shale anyway... freezing temps don't make it any harder to dig up.
