Science: Of Green Energy

Very interesting find in Newcastle...

No, it's not beer. We knew about that already. What has been found deep (miles deep!) underneath the venerable city is hot water. Hopefully a lot of it. Because, if there's enough, it can be used to heat most nearby buildings in a very cheap, and very clean way. A side effect of the drilling exercise is also quite a lot of other scientific finds from various fields: geology and archaeology to name just a couple. But there's a wider thing to be noted here. Surely with the advances in deep drilling technology it will become increasingly possible to tap into energy of the Earth's core by literally tapping into reservoirs of hot water deep within the crust. Not to mention that one does not necessarily even need water to be present deep down. We can always pump down some of what we have in abundance above the surface to be nicely heated and the heat used where it can do useful work. As far as I understand there are plenty of sites where this could be done given adequate technology at an adequate price. But, for whatever reason (cost?) this particular way of producing clean energy gets nowhere near the coverage of solar, wind, and even tidal power. For what it's worth, my personal feeling is that geothermal will eventually trump them all.

Here's raising The Dog to seeing geothermal shine in my lifetime...
