Paper on SOLAR COIN, 2018

“Ethical Markets is proud to be a Media partner with SOLAR COIN, www.solarcoin.org because it is the only crypto which is a reward currency that can only be earned by proving to a third party verifier the kilowatts or megawatts of electricity generated from the free photons from the sun!  Thus Solar Coins are tethered to a real world commodity: solar electricity, more valuable than gold!
