Navigation didn't work for some stuff on mogile but I dowloaded the PDF whitepaper and I must say this is more shallow than most "tokens".
If I understand correctly, people invest money into a pool that is distributed for companies/industries to spend, in order to increase their energy efficiency. Once they are done ("once" should be "if"), part of their savings goes to the investors. I think it is reasonable to assume that such process doesn't need any crypto proof and ultimately depends on lawyers, salesmen and bankers. Making a company or an industry more efficient requires talent and strategy, not just pouring money and it is a very risky and long process. If these guys feel competent to make a profitable energy efficiency fund, they should start one. And with clear legal protection for the investors, not a token.
