2.2. Scenarios for forcing energy balance closure Closing the energy imbalance was done by distributing ɛ to the three energy balance components, A, λE and H, in weighted portions (w), so that the adjusted values (marked with a *) become(11a)λE*=λE+wλEε,(11b)H*=H+wHε,(...
The inventors of the internal combustion engine understood that petroleum held a large amount of energy. Can you think of any other substance that can take you and 2,000 pounds of car 30 or more miles on just a gallon? Few people can, which is why gasoline-fueled cars have been the nor...
