Using bio-ethanol indirectly

ScienceNOW’s daily news reported yesterday on a study that claims that biofuels are more efficient if they are turned into electricity than used in cars.

It’s an interesting thought: if we turn the crops and wood chippings into electricity instead of bio-ethanol, and then drove electric cars, this could well have a positive change on the emissions.

Turning biofuels into electricity on a large scale could well mean that the CO2 emissions even better controlled, thus meaning less of it getting back into the atmosphere.

I wonder whether other studies will support their claims?

Do your homework, Mr. Bond!

I finally got to see the film Quantum of Solace on DVD the other day, having missed it in the cinemas.

Part of the action supposedly takes place in Bolivia.  I say “supposedly”, because I recall that a number of outside shots were actually done in Chile – much to the anger of the local mayor, who objected to his community portraying Bolivians. (The area concerned had actually been part of Bolivia until 1883).

In fact, very few of the scenes were actually shot in Bolivia itself.  Even La Paz airport, which I was suspicious of when I first saw the scene, turned out to be at Farnborough in the UK!

But there were two things about the Bolivian scenes that I spotted right away.

Firstly, the roads.  Those roads to the hotel in the desert were too new!  I don’t remember the roads between the main towns being that good.  In fact, I remember in particular the road out of Potosí on the way to La Paz being of a high standard until about 5km north of the town.  Then it reverted to the usual dusty and bumy version for the rest of the journey.

However the line that really caught me off guard was at the party in La Paz.  The character Dominic Greene said that Bolivia had a water problem, because they had cut down so many trees that the topsoil had sliden into the sea.

Now, quite apart from the fact that I was not aware of such activities on Bolivia (I thought that was one of the problems in Africa…), which “sea” exactly would that be?

E85 and Diesel

I came across an article in the USA Today archive recently.  It compares the prices of bio-ethanol to normal petrol and in particular to diesel.

I had originally planned to buy a diesel car before I found out about bio-ethanol.  I wanted the cheaper fuel and the ability to drive further on one tank of it.

But in Germany, diesel cars are taxed more.  So unless you manage a certain amount of kilometers each year, the saving on the fuel is cancelled out by the higher tax.

These days, diesel drivers are unhappy that the price of their fuel has almost matched that of normal petrol, making it bizarrely more expensive to drive a diesel car than a petrol one.  The only benefit is the distance that you can get without having to fill up again.

Since I tend not to drive long distances with my bio-ethanol car, it looks like I took the right decision after all.
