Essentially, I want the liberty to travel anywhere globally in my own private craft... That is what excites me about this more than anything else, and why I wrote this story. There are some other interesting real-world electric aircraft developments already in progress, but none as yet that reach for the scope Musk speaks of here.

While I am certainly in general agreement that we need to be better stewards of the planet, I need to study the numbers and the whole "global warming" thing before I get to the alarmist stage about climate change. I am no fan of big oil, but my general viewpoint is that carbon in the air is more of a health problem (CO and other chemical compound byproducts) than a global climate change problem.
