Interesting comment. There are trials occurring. What I like about PowerLedger is the potential. The POWR token is like a license to trade power, using some sort of microgrid system. Sparkz tokens will be used to make payments, with its value linked to the local currency. I think it's an awesome project. It's got me thinking about whether it would be a profitable enterprise, to set up a solar power system to provide solar power to a small town.....using the PowerLedger technology. If so, it's an enabler....and I think blockchain technology and electricity supply are a natural business fit:) Undervalued? HODL....
