TDR


Today I’ve finally bound my research work! I think I have never talked about it here. I started it last year (well, like everybody does in Batxillerat) and after the summer, Christmas Holydays and January, it is already finished.

The topic of my work is basically hydrogen (against petroleum) and that’s why I put the “Oil clock” in this blog, because after doing this project I am aware of the huge problem which is petroleum.

We have to give it on Thursday, the 5th of February, and we have until 18:00. I still remember when I started Batxillerat and teachers said “You have to do it in summer” and they repeated it almost every day. Now, as usual, it hasn’t been finished until the last week.

I think it’s one of the two worst nightmares we will have this year in 2nd of Batxillerat. The other one, of course, is the Selectivitat, also called PAU or university entrance examinations. Now, the first one is, more or less, over, and it’s time to face the second one.

I say “more or less” because it hasn’t finished yet. The 18th of February is the day of the oral presentations, in other words, we have to explain our work in 15 minutes in front of a jury made up of three people that will evaluate the works. This year there have been many works and there’ll be more turns than last year, but now I don’t remember how many turns there are because I am in the first one, between 3:15 and 4:00. Some people say it’s good, because when you finish it you are calm while other people are still nervous. Maybe it’s true... but I won’t believe it until I watch it.

The first picture of this post is one of the images I haven’t been able to put in my work. It’s liquid hydrogen in a bubble chamber. And here I put another one that I think is very interesting but the resolution is a bit low. It shows what happens when a car filled with hydrogen or gasoline burns. If you didn’t know, the first one is the hydrogen car, and the other car contains gasoline.

Do you still think hydrogen isn’t safe?
