I can tell you the few events I have attended with the SolarCoin/ElectriCChain teams, solar industry people are at first confused, then amazed by what we are doing, and not just the fact that we are trying to incentivise their entire industry at a global scale.
People are amazed that we can, with a cheap device like a Raspberry Pi, log solar generation data to an incorruptable, free, open database from ANY size of solar install. Big solar PV installs are easy, but getting data from the thousands of domestic systems, has been (from what a national energy company told me) impossible.
So screw the haters, we have something here that no-one else has, if the $0.12 guy cant see it, plenty of others will; if you build it they will come.
Bravo!
