The density of thermal energy contained in the core of a light-water reactor (pressurized water reactor (PWR) or boiling water reactor (BWR)) of typically 1 GW (1000 MW electrical corresponding to ≈ 3000 MW thermal) is in the range of 10 to 100 MW of thermal energy per cubic meter of cooling water depending on the location considered in the ...

The internal energy of a thermodynamic system is the energy of the system as a state function, measured as the quantity of energy necessary to bring the system from its standard internal state to its present internal state of interest, accounting for the gains and losses of energy due to changes in its internal state, including such quantities as magnetization.

The apps collecting the most data about you are among the most widely used. Kurt the CyberGuy takes a look at 20 of these apps and how you can protect personal information.
HBO's Bill Maher took a victory lap over the NFL's decision to drop its "end racism" message from the end zones at Super Bowl LIX, insisting it would make racists "more of a racist."
If the final energy delivered for consumption is E and the EROI equals R, then the net energy available is E-E/R. The percentage available energy is 100-100/R. For R>10 more than 90% is available but for R=2 only 50% and for R=1 none. This steep decline is known as the net energy cliff. [28]
