Always search for critical reviews, especially when there is no evidence presented in the video. http://thrivedebunked.wordpress.com/201 ... m-trombly/
raises some valid questions.
From what we know of the rule-set, free energy is an illogical concept. Entropy prevents it, there is always loss in energy transformations. "Loss" means the energy can't be retrieved without spending more energy on the retrieval process itself, it is thus irreversible. The energy is forever lost as the heat dissipates throughout the cosmos.Exergy
is an useful concept: "Energy is never destroyed during a process; it changes from one form to another. In contrast, exergy accounts for the irreversibility of a process due to increase in entropy. Exergy is always destroyed when a process involves a temperature change. This destruction is proportional to the entropy increase of the system together with its surroundings"
I sometimes contemplate on our economics as whole (or in part), to be based on Emergy
or some equivalent concept.
"Emergy is the available energy (exergy) of one kind that is used up in transformations directly and indirectly to make a product or service. Emergy accounts for, and in effect, measures quality differences between forms of energy. Emergy is an expression of all the energy used in the work processes that generate a product or service in units of one type of energy. The unit of emergy is the emjoule, a unit referring to the available energy of one kind consumed in transformations. Emergy accounts for different forms of energy and resources (e.g. sunlight, water, fossil fuels, minerals, etc.) Each form is generated by transformation processes in nature and each has different ability to support work in natural and human dominated systems. The recognition of these differences in quality is a key concept of the emergy methodology."
It would totally optimise the dynamics between the human civilization and our environment and its finite natural resources. Essentially changing perspective from very short term to long term thinking.
