Putting the life back in science fiction


Syria, Part II

Confession time: I can’t stand to watch the videos of Syrian people suffering and dying from the latest Sarin attack.  Since I have asthma, I may very well die gasping for breath, and this particular horror strikes too close to home for me to watch.  Here’s Charity Navigator listing their best charities for the Syrian conflict.  Or you can give to the UNHCR for Syria.

Anyway, I decided to look back at my 2013 post on the Syrian Water War, to see where we are 3 1/2 years later.  Has anything changed?  Is there anything we can learn, especially with the current regime in the White House? Continue reading



Tekelili! The Wilkes Land Gravitational Anomaly

Another little post, this one on a news item a few months old.  Whenever someone spots a gravity anomaly in Antarctica, people get silly, write things about how the tinfoil hat brigade think it’s a UFO, or an alien base, or NAZIs.   They’re so silly.  Of course it’s shoggoth (not sure what the singular or plural is.  Since shoggoth is sort of like concrete or nanotech, is it singular, plural, collective singular, collective plural, or what?).  Anything that close to the Transantarctic Mountains has to be.  it’s canon.

More seriously, there’s some potentially interesting science buried under the ice.   Continue reading



XKCD strikes again

Got to hot link this one (here’s the permanent link).   I suspect some climatologists will grumble about how smooth that line is, and I caught one probable error and a couple of maybes (dates in the middle).  Otherwise, it’s his usual thought provoking work.

Labor Day Silliness: America as Rome, part duh

While I don’t want to kill the previous conversation, I’d like to post a rather silly question, if you’ve got some down time this weekend and want to swat at it.  The idea is based on the USA kind of following in the caligulae of the Roman Empire as it crashed.  The question is, when Washington DC floods due to sea level rise, what city becomes the new capital, the American Constantinople?

Facepalm with a hit of nitrous

I’ve been advocating for a partial switch to an ammonia-based economy, on the theory that, while NOx is an air pollutant, it’s better than CO2.

Facepalm time: N2O, good ol’ nitrous oxide, which is another thing that comes out of of using ammonia for fertilizer or burning it, is a greenhouse gas 100 times more potent per pound than CO2.  Right now, it’s 5.9% of US greenhouse gas emissions.  It supposedly lasts about 114 years in the atmosphere, until it gets broken down by some process or other (I’m being lazy about all the bits and bobs in the nitrogen cycle, because it’s hot here, and with a flex alert on, I’m not running the AC). Unlike CO2, it doesn’t look like it sequentially saturates large sinks and stays around for hundreds of thousands of years in the atmosphere.  Rather, it just breaks down slowly.  About 40% of the N2O emitted in the world is from human activities, and it can be cut, in some circumstances, through catalytic conversion technology.

Here’s some really basic information on it (link to EPA)

The basic sources for atmospheric N2O are:

  • conversion of nitrogen fertilizers to N2O by bacteria.  This is the big one, and more efficient fertilizer use and better land management can cut this to some degree.
  • it’s a combustion byproduct, so it comes out the tailpipes of gas-burning cars.  Catalytic convertors can help with this.
  • various industrial processes produce N2O as a byproduct.

Now, the simplistic solution is hydrogen, except that (IIRC) burning hydrogen using air also may release some N2O, because there’s a lot of nitrogen in the air.  Converting to fuel cell-type devices that do electrochemistry rather than combustion and using catalytic convertors on combustion-powered systems probably is the way to go.

It does get more complicated than that.  While catalysis is the simple-minded solution, it’s also prey to the usual simple-minded problems with polluters who don’t keep that part of their car (or other system) working, and thieves after the platinum in the convertors.  It’s the usual, intractable problem: environmental problems, greed, and stupidity don’t mix.

So, what do you think?  Pitch any desire for an ammonia economy out the window and pray for hydrogen and better batteries?  Double-down on catalysis, which catches NOx better than CO2, and start prospecting for platinum at the side of the local highways?  Stick with fossil fuels and assume we’re all doomed?  Some combination of all three?

Oh well, tonight I get to watch  the latest episode of the newest superhero series: Suit Woman vs. Generalissimo Cantaloupe.   I’m not sure binge watching is the right word for it (more the opposite), but it does seem to be the thing everyone’s talking about this season.



Why more droughts matter more than some droughts

So I’ve finished reading 1177 B.C., The Year Civilization Collapsed, as I mentioned in the last post.  It’s a good book, and it’s also a good lesson in why I might want to wait until I’m done reading a book before blogging.

It turns out there’s multiple lines of evidence that there was a drought in the eastern Mediterranean around 1177 B.C.  However, if you know anything about Mediterranean climates, you’ll know that droughts happen.  Was this one different?  That part’s unknowable, but a book I read earlier this spring does point to how the eastern Mediterranean can get into a big problem when two droughts coincide, and that’s the little lesson for today: it’s not just the local drought that’s the problem.

California’s (possibly) electric future

Wow, the last three weeks were not fun, but that’s not what this entry is about.  I’m back, and regular entries are resuming until the next little crisis kicks up.
