-Discussed at [[connections-20080112]] 
  
-  * [[Helmut Burkhardt]] respects [[Howard Odum]]'​s work, but has some issues because Odum isn't a physicist. 
-  * [[Helmut Burkhardt]] attended a workshop by [[Howard Odum]] at a workshop on //The Prosperous Way Down//. 
-  * Burkhardt says that solar energy is plentiful, but Odum said that it was too diffuse. 
-  * Odum also said that the energy was highly distributed,​ it doesn'​t have quality, e.g. oil is concentrated. 
-  * Correct: second law of thermodynamics. ​ The quality of the energy depends on the source, e.g. oil is about 3000-4000, whereas solar energy is 6000. 
-  * Technical efficiency is 95%, oil is 65%, bioenergy is 1%; thus, would need to collect a lot more. 
-  * [[Helmut Burkhardt]] admires [[Howard Odum]]'​s creativity in ecosystems, but Odum is working on some wrong assumptions. 
-  * Problem is theoretical. 
-  * Engineer'​s concept: ​ entropy law is backward, you get more of something negative, not something for nothing: ​ exergy 
-  * Energy as the ability to do work, that is nonsense. 
-  * There'​s lots of heat energy in the ocean, but can't get to it. 
-  * Ocean energy as waves, kinetic is pure exergy. 
-  * Exergy is the part we pay for. 
-  * Odum created a concept of emergy; Burkhardt is not sure that this is helpful. 
-  * James Kay uses exergy, less controversial.
