This sounds amazing, but I am not seeing too much yet about curriculum or what and how they are actually going to teach. It's probably too early but would be interesting to see. I think the main deciding factor about big projects like these being effective for our community's growth is the people and leadership behind the project. If the leaders and teachers are deep in sikhi, then naturally the students will be more drawn towards sikhi itself and the values will carry on. Hopefully it is not the case where the admins are in it for the money and status and could care less about the values and so the kids end up only somewhat better or worse as they would've if they went to public school. We need more projects like these working well for the community as it gives hope to change our current systems.
Which western country you based at? I think it's a very bad idea. If you have no money there you will be ill treated and oppressed by almost everyone. I don't recommend sleeping outdoors under any tree as it is highly unsafe for women and many unsavory characters that are drunk or high on drugs prowl the countryside looking for easy targets. At your age there's the serious risk of developing diseases etc.
As an alternative you could immerse yourself in Gurbani,Keertan,Katha,Simran in the comfort and safety of your home or the nearest Gurdwara.
