Charge a phone battery (the hard way)

Our group is composed of Maxime Oçafrain, Florian Fabre and Tom Avril. We decided to talk about the renewable energies at first, but then we found a new key question : How to charge  a phone battery using the lab equipment ?
To answer to this key question, we realized 5 experiment to try if we could or not use these  equipments to charge the phone battery : - Generator and computer
                                                                  - Strirling Engine
                                                                  - Solar Panel
                                                                  - Windmill

Here is how a stirling engine work.

The stirling engine take a big place in our porject cause we, at first, choosed to work only on this.

The principle of how the Stirling engine work is really interresting, cause it mix-up thermodynamic and fluid mechanics.

An exemple of montages that we made. Here trying to charge a phone battery using a solar panel.

 We conclude saying that it was just impossible to charge a phone battery using the Stirling Engine cause of a problem of resistot difference from the battery. Every other experiments were succesfull.

  Friday 30 november  we meet greek students who are 16 years old .
  We asked them a few questions of there habits and the greek cultur .
  Like "Have you ever surf ? " they never surfed before we explain that to them .
  And if they can visit our city and they said no , but they asked us if we can visit Greece
  and we said no . That's makes me sad because they look kind

Greece 2015

 We talked with our Greek students and they asked questions and to us too.
Some questions were about the school and others about sport or country.
We sang  " Petit Papa Noel " and they sang a greek song but I don't remenber what song.
In Greece, they talked to us they have one hour more than France. They said too about the crisis and its devlopement in the country.
The conversation lasted one hour and it was very quick.
And we finished to speak about our next holidays
