The gullibility and naïveté of those in the FE field, combined with libelers and other criminals in the ranks, are partly why, soon before he died, Brian said that if anybody brings FE to the world, it . I have either participated in, witnessed, or heard from fellow travelers all of the above approaches numerous times, and there are far more written accounts of such approaches readily available. As I watched them play out many times, it became disheartening to watch the same paths to failure doggedly pursued, often by the aspirant-of-the-hour, usually an inventor, who always thought that he had some magic formula that would work even though many thousands of his professional ancestors failed. All of those methods are ways to give our power away to someone or something else, pour the new wine into old skins, and generally act from a scarcity-based and victim-oriented perspective. None of those approaches have come close to working or are likely to. Newcomers invariably advocate some kind of shortcut, an easy path to the finish line. There are not any. The is not something that can be initiated in an afternoon, a month, or a year of effort, and I have watched many lifetimes expended in the pursuit, including mine. Nothing about this is easy, and I have helped the best of the best spend their lives trying. With a sufficient nucleus of enlightened people, it could be an easy task, but achieving that nucleus is the hard part.

Once the energy is delivered into a gas tank or turbine boiler, the efficiency of turning that chemical energy into mechanical energy is what first dealt with. Mechanical energy is called , whether it comes from human muscles, the muscles of draft animals, or machines. Also, the concept of power is critical, which is the amount of work performed over a time period. How quickly energy can be released and used is the crux of how rockets work, for instance. To get more power, more sophisticated technology was required, from taller masts in sailing ships to stronger components for watermills to high-performance engines (which run hotter with greater pressures). Generating more power was always a technological feat but was dependent on how much energy could be delivered and utilized and how quickly.

Unless we use the power of persuasion intended for whatever purpose such as to sell something or influence your intended target of something.

said that if oil were priced by the benefit that humans received, every barrel should cost $1 million. But because it takes relatively little human effort to obtain oil, it sells for only about $100 per barrel today (and $50 in early 2015, as another is collapsing). Similarly, the Sun’s energy powers the , without which there would not be land-based life. If humans had to desalinate water instead of rely on the Sun for the energy to provide fresh water, and humanity did not have an energy source such as fossil fuels, humans would quickly go extinct. But because nature provides the water that humans use and nobody pays for it (a concept that is eroding, as corporations are busy ), neoclassical economists ignore the critical economic benefits provided by the hydrological cycle. Homogenizing everything with market prices and then creating differential calculus analytics is not helpful for understanding how the world really works. Neoclassical economists have tried to divorce energy consumption from economic production, but such analyses only have seeming validity if the way that the world actually works is ignored. American food production takes nearly 20% of the USA’s energy use, and more than 10 calories of fossil fuels are burned to provide every calorie of food eaten. The concept of diminishing returns and energy consumption applies to national economies. Poorer nations receive a relatively large benefit for incremental energy use, while the industrialized nations do not get as great a proportional increase. But statistics such as worker productivity in the USA had a tight linear relationship with energy use for 80 years, from 1905 to 1984, when the Reagan administration ceased collecting the data.

In 2013, average Americans used about 80 times the energy that was provided by their diets, which has been called having 80 energy slaves, but that understates the reality. A barrel of oil provides about one year of the calories needed to fuel a human body, but if that oil were used to power machines, it would perform more than ten man-years of work, often doing work that humans could not perform in any case, such as propelling an automobile. Each American really has several hundred energy slaves working for him/her, which is why the average American lives a richer lifestyle than Earth’s richest human of two centuries ago. In 2013, the energy in the oil wrested from Earth’s crust contained enough energy to power several hundred energy slaves. Add in the other energy resources, and industrialized humanity rode on the backs of about one energy slaves. In today's industrialized nations, humans perform a tiny fraction of one percent of the actual work done; energy-powered machines perform more than 99.9% of it. In contrast, the reproduction of intelligence is in its infancy. In 2012, humanity's 500 most powerful supercomputers achieved the combined computing power of three human brains. The day that each human has even one "mind slave" is a distant future event.
