The Russian situation

Saturday, August 16th, 2008

The short war between Russia and Georgia is technically over, but things are far from settled. Both presidents have signed a truce that essentially puts things back to the way they were before the war. However, the Russians say they are staying where they are, deep inside Georgia, until an international force arrives to monitor the ceasefire. Until Russia leaves Georgian territory, anything could happen. There have also been rumors that Russian troops are not allowing some aid into Georgia. The group Human Rights Watch has alleged that Russia was using cluster bombs against Georgian civilians. According to them, cluster bombs have been banned by 107 countries.

While Russia is seen as the villian here in the West, Georgia is not at all blameless. South Ossetia won de facto independence from Georgia after a civil war in the early nineties. However, it is still considered to be part of Georgia by virtually everyone. This whole thing started when Georgia tried to regain South Ossetia about a week and a half ago. If you ask South Ossetians, Georgia is the villian and Russia is the protector. Of course, the whole thing had been brewing for years.

Ties between Russia and the US had already been strained by this whole situation. However, on Thursday, Poland signed a deal with the US to host part of the US missile defense system. This did not sit well with the Russians. They say it “cannot go unpunished” and have threatened military action against Poland. Poland is part of NATO, so if Russia followed through with their threats, things could get interesting quickly.

Ethanol in gasoline

Wednesday, August 13th, 2008

Sunday on the way home from Belmont we stopped in Pontotoc for some cheap gas ($3.40 to be exact). There was a sticker on the pump that said “Enriched with Ethanol.” Someone had taken the liberty to cross out “Enriched” and had replaced it with “Diluted.” While I deplore vandalism, I was a little amused that someone felt so strongly about the situation.

I had previously heard claims (on the local talk radio station) that gasoline with ethanol added gave you worse gas mileage than straight gasoline. I had never given it much thought, but the vandalism made me curious.

The most definitive numbers I could find were in a report from the American Petroleum Institute (page 9). The API is a trade association for the US oil industry, so, if anything, you would expect their numbers to err on the negative side. The report cites a small study using 2001-2003 model year cars and light trucks that shows a 1.4% fuel economy penalty when using fuel with 10% ethanol, the most common mixture. They cite another study using older cars (1989 models) that shows a 2.6% fuel economy penalty.

Let’s use the number for more recent cars: 1.4%. That means if your car gets 25 mpg with regular gasoline, it’ll get 24.65 mpg with 10% ethanol. That doesn’t sound like a big difference, but if regular gasoline is being sold for $3.59 a gallon then gasoline with 10% ethanol would have to be $3.54 or cheaper to make up for the decrease in fuel efficiency. So, keep this in mind and buy your gas accordingly.

Of course, if the US taxpayer wasn’t subsidizing the production of ethanol then this wouldn’t be an issue, but I digress. That is, perhaps, a blog post for another day.
