#4695: It's because people don't understand the Laws of Thermodynamics

Karl Denninger has a post up about this so-called "green diesel" which is the latest and greatest, supposedly, from Audi.

"German car manufacturer Audi," he quotes, "says it has created the 'fuel of the future' made solely from water, carbon dioxide and renewable sources."

The problem is, this isn't an energy source. It's a storage medium: you have to put energy in to make the water and carbon dioxide into fuel. And when you're talking about a storage medium--or any energy system, really--you must include all the energy inputs, not just the ones you like, in order to come up with an efficiency rating that resembles reality.

Getting your energy from "renewable sources" means solar and wind, two sources which do not reliably generate power at industrial quantities. You can get megawatts from big wind farms or solar installations, but you cannot get them on demand at all times, and if you cannot schedule production, your production will be erratic and therefore undependable.

Denninger correctly points out that it's much more desirable to use nuclear power as the energy source for a process like this. He also points out that this process is neither new nor revolutionary.

You can't get something for nothing, guys.

Iran captures US-flagged ship, releases it several hours later when Tehran realizes what kind of problem this would make for their nuclear aspirations.

Of course, the GOP leadership is saying that it doesn't have the votes to stop Obama's Iran deal, so they're not going to try. That's the GOP in the 21st century for you.

Useless. All of them, completely useless.

Mrs. Fungus and I have been re-watching Game of Thrones from the beginning, and it's entertaining to see how characters were when first introduced and compare them to where they are now (in the latest season).

I've eschewed getting further into the Baltimore junk because it's all depressing crap, more of the same-old-same-old progressive politics. (Both "cause" and "effect".) What else can be said about it?

Nothing else to discuss at the moment, either. I suppose I should cut the grass today, and I have an errand to run, but I'm not doing that right now. This is my day off, and I am allowed at least a little extra sleep, am I not?

  • #7558: Yeah, I thought that sounded kind of strange.

    What if they held an insurrection and nobody came? Wednesday night Mrs. Fungus was telling me all about how the news said there was going to be a…

    Kid is ranked 62 out of 120 with a GPA of 0.13. What's his mother have to say? He didn't fail, the school failed him. The school failed at their…

    I don't get to make it very often, but I saw a really nice piece of round steak at the store the other day, so I bought it. 1-1.5 lbs beef (round…
