Only an anger with God himself, with oneself or the continued existence of mankind in the longest term would prevent any switch in fuel systems that include the switch from trees and coal to oil or the change in engines from steam engines to an internal combustion engine. The same anger would delay for decades and possibly centuries, the switch to zero-emissions fuel for mass transport. What is the source of this delay? Is there some emotional impediment that prevents men from doing what is the most prosperous and logical economically. Who stops individual nations from forging ahead in energy independence? Brazil is energy independent in many respects with a transport fuel system based on ethanol produced domestically on fields of sugarcane created from clearing forest in the amazon jungle. They may be energy independent but environmentally independent. They(Brazil) need the trees and forest for oxygen while hydrogen fuel produced chemically from various sources allows a degree of environmental independence and energy independence. Is there some issue in conceiving of the oil industry first and foremost as just an energy industry? The purpose isn't selling oil, coal or trees to fire up engines. The purpose is to power and fuel engines and this can be done using abundant hydrogen(emissions free) energy. This is an energy industry and not an oil industry. Hydrogen energy allows for an environment in which to enjoy transport. Transport in a depleted and oil-destroyed environment does not encourage other industries such as travel and tourism. There is need for long term vision. There is need for balance. All of creation is crying out for the sons of God to be revealed(Romans 8). This is important before someone tells an actor in some glossy movie sometime very soon, once again, to talk about "..The desert of the real" and to say that "...nobody knows what really happened." Look at the Cadillac CTS 2.0 T hydrogen fuelled prototype and the Audi E-Tron Spyder Prototype. The various designers work for GM now designing hybrid trucks apparently that obtain an exciting 53.1953 mpg. It's really sexy and big. Unfortunately, the tendency to have psychologically impoverished hillbillies in positions of environmental consequence is that they will not only tell you that "..this is just how it is", they will tell their children as well; especially their daughters. But, in spite of the number of generations that have to endure the environmental rape with led and carbon pollution and the emotional rape at the gas pump, it doesn't make it right.
