definitely not the first project to venture on green energy. but the usual problem here is the seriousness of the team to actually proceed with their actual development. most are just using this as a front to attract buyers, but once they filled their pockets, the main mission is forgotten. so i don't know if they can actually realize their platform or not, with or without collecting funds?
indeed a lot of old projects derives a lot of money from investors that trust the vision of the team but a lot of those projects did not end well.
