The idea of protect nature and environment are good but the profitability of this project remain the same .there aren't enough chance to have large profit because the system you want to use it will need quite large investment.to recover this huge amount it will take time also.
Every business needs a time to recover it's money so they will need time also .But i don't think they can collect their amount by like this.they need to investor who will belive this idea and invest in it.as we see for many reason the ico aren't get that much attraction now.so it's not sure to collect the money.hope for the best.
