Hal Partenheimer is a freelance writer based in Dallas, TX. His passion for the environment, energy, the folly of "catastrophic" climate change, and new technologies that address them all take him to wildly exciting places. Writing about them keeps him in a state of happy harangue. Hal has a B.S. in biology and geology and has spent more than enough time in the oil patch of the Permian Basin.
