Fuel from the Sun

April 2, 2013 By Geoffrey Ozin Leave a Comment

Imagine life in a ‘clean house gas’ rather than a ‘green house gas’ world; this will require a change of human behavior from that practiced in the Anthropocene era where the Earth’s ecosystems have been negatively impacted by humans to the Sustanocene age where humans strive to heal the Earth through renewable technologies to make things better.
