Anglais

Bonjour,
J'ai un projet à faire pour vendredi je l'ai fais mais il y a des fautes, si quelqu'un pourrait corriger les fautes s'il vous plaît merci. Et je souhaiterais ajouter quelques phrases sur le projet mais je ne sais pas quoi dire



We are three high-school pupils and we have a problem because we sleep when we are in class, that’s why we wanted to invent a project in order not to sleep.
Our first idea was to put matches on the eyelids (paupières) of eyes but it was not discreet and it was dangerous and stupid. The second idea was to create a watch with electrical discharges (décharges électriques) but not to sleep was difficult and it was dangerous again.
The third idea and the worst idea was to put an objet which smashes on the face of the person who is sleeping on the chair but it was not discreet again.
The best idea we had was to create a necklace Hologram so we worked day after day and we spent a lot of our money. To begin, we needed to create a furtive project to put in our bag and this object had to be beautiful and light so we thought we could create a Hologram.
The necklace’s utilization is very simple. There is a button and when we press it, the Hologram shows our image.
The light of Hologram reduces or extends automatically varies from the light of the room.
This invention works with solar energy. But we have introduced a battery with an autonomy of three hours when there aren’t light.
Now since with this invention we can sleep in class when we are dead tired (quand nous tombons de fatigue).

Un hologramme en forme de collier...

to the eyelids est correcte ?

"to the eyelid" peut passer

"an autonomy of three hours when there aren’t light"
En fait j'ai laisse passer d'autres fautes dans la phrase:
- there = un lieu
Ne pas confondre avec la contraction de "they are" qui est "they're" ou encore le possessif "their"

- Tu veux dire "les colliers ont une automonie de 3h quand ils ne sont pas allumes"
etre allume = to be on
to be lit = etre illumine (par la lumiere, pas etre fou)

Ce que je voulais dire est que les colliers on une autonomie de trois heure grâce à une batterie et celle-ci se fait recharger par l'énergie solaire (s'il n'y a pas de lumière ou en cas d'éclipse ou autre au moins l'hologramme fonctionne).


Mis à jour cela donne :

Merci beaucoup.

Ca en a l'air.
