Liam, frankly I'm very limited on fuel-cell technology and their benefits. If this is the way you are thinking of going it does sound really interesting. Perhaps you could narrow your search down to one item that fuel cells help run and compare that to traditional ways of running the item with oil. As far as Costa Rica goes, that is way to broad. Perhaps narrow it down to tourists and one national park and why the tourists are hurting it. I hope my ideas help you, as limited as they are. I do think that if you narrow your search down you'll get better results.
