hey biophil, one question : if you had a generally accepted way for accounting energy transfers, it would be possible for you to calculate an accurate energy balance?
...thats the basic idea behind emergy, putting different kind of energies into comparable units.
The problem with emergy is that is not 100% exact theres always uncertainty.
I ve read also that its possible to measure the amount of uncertainty of emergy calculations, but i dont know what can be this useful for.
If there is a margin of error in emergy calculation , what do you think about using all the nodes ( owners of emergy coins) in the net to fix in a collaborative way this error and get a consensus of what is gonna be the fixed value?
Tipon, emergy is a fun theoretical concept, but I'm guessing that in this system you're envisioning you'd need to tabulate emergy values for all different types of energy conversions. Do you have any idea how difficult that would be to do accurately? I worked in the renewable energy industry several years ago and we never were able to calculate an accurate energy balance for our product alone, much less for biofuels in general. The problem wasnt that we didn't try; it was that there is no generally accepted way to account for energy transfers. If we accounted for it one way we'd get vastly different values that if we accounted for it another way. I think emergy is a useful concept because it threatens our intuitions about how energy works, but I'm not sure it has great practical quantitative value.
Furthermore, how could you ever create a cryptocurrency that "knows" how much emergy this or that thing has, when humans can't even calculate precisely how much emergy it has?
I'm not trying to shoot down OP's idea, but I'd love for him to elaborate a little on how it might work.

I think computing energy balance is still hard and maybe even chaotic. Think about energy balance for a liter of biodiesel:
One energy input is the electricity to run the plant and keep the lights on. This electricity comes from some combination of coal, nuclear, and renewables. Let's look at the nuclear: uranium has to be mined, transported, refined, and when its gone through fission, the waste has to be disposed of. All of those steps require energy. Take refining: the centrifuges have to be built somewhere, and it costs energy to do that. You could keep playing this game forever.
The point I'm trying to make is that it's computationally infeasible to compute an accurate energy balance because the energy web is so tightly interwoven. The only way you can figure out a product's energy cost is to make some educated guesses along the way. There's nothing wrong with that, but you could never guarantee that a mistake somewhere wouldn't throw the whole calculation off. Throw eMergy into the mix and you dramatically increase the complexity of an already-challenging problem.
