I'm back!

I first joined this platform 6 years ago, as I was interested in the concept of rewarding content, curating etc. but I was too busy to become active in a new social platform. Now I am retired (from NASA) with more time, and interest in blockchain based tools. I intend to explore what communities and content are available here, and I hope to be able to contribute. I am particularly interested in content related to clean energy, carbon capture and, in general, climate stabilization technologies. I am interested in ideas for creating carbon utilization markets.
