Nuclear electricity generation is relatively inefficient but the process can be adapted to provide heat and power in a nuclear combined heat and power (CHP) plant.
He calls such trade "virtual water", referring to the water consumed to produce food.Desalination to provide water for agriculture is almost always economically inefficient because the process consumes so much energy.
Although in vitro reprogramming systems that can restore pluripotency in somatic cell have been designed, they are still very inefficient and the process requires considerably more time than the reprogramming processes that occur in vivo.
In summary, the practical application of the Carnot cycle is limited because of the inefficient compression process, the low work per cycle, the upper limit on temperature for operation in the two-phase flow regime, and the irreversibility in the heat transfer from the heat source.
But when it comes to sustainable starting materials, such as wood chips, corn stalks, or other plant "biomass," refineries are too inefficient to make the process commercially viable.
Oh, if only we could replicate the relative poverty, the limited consumer choices, the inefficient production processes, the massive trade barriers that compelled Americans to buy American, and the uneconomic work rules and wages commanded by once-powerful private sector labor unions.
Rust: Two things: 1) How totally inefficient the clean up process is at some of these Superfund sites; and 2) that despite continuous cleaning and treatment, many of these sites aren't actually going to get clean for hundreds of years.
The costs of development of the host defenses come primarily from the expenditure of energy to fuel the inefficient process of an effective immune response and to provide substrates (e.g., amino acids and lipids) for the production of effector leukocytes that protect the bird from infections [31].
I had to wait about 3-4 hours in front of the polling station because of the inefficient process.
The main barriers identified in phase 2 were the inefficient communication processes between the ED and the blood bank at the time of prescription, at the time of reconstitution and at the time of delivery of the reconstituted product from the blood bank to the ED.
