Keeping it brief, if you're interested hit me up.
The concept is stupidly simple, solar energy. Currently solar power requires expensive installations using smart meters, inverters, trust in the central operator, etc.
Linking renewable energy to a cryptocurrency, while clever, still requires trust in the authenticating party. The resulting legal overhead limits projects to large scale applications totally defeating the advantage of decentralization.
Instead what if solar energy was plug-in-play? USB PD power distribution allows for bidirectional energy sinking and sourcing along with data transfer. Seamless authentication, IOTA credit, power dispatch, no power brick necessary, carbon free, lower cost.
