Not sure if this is anyones cup of tea. but as I comment and read and explore permaculture this song gives me chills and gets me worked up.
its called 2nd law. which is a reference to the second law of Thermodynamics.
one quote from lord Kelvin....
Lord Kelvin expressed the second law as "It is impossible, by means of inanimate material agency, to derive mechanical effect from any portion of matter by cooling it below the temperature of the coldest of the surrounding objects. This may be restated as“No process is possible in which the sole result is the absorption of heat from a reservoir and its complete conversion into work.”This means it is impossible to extract energy by heat from a high-temperature energy source and then convert all of the energy into work. At least some of the energy must be passed on to heat a low-temperature energy sink. Thus, a heat engine exhibiting 100% efficiency is thermodynamically impossible. This also means that it is impossible to build solar panels that generate electricity solely from the infrared band of the electromagnetic spectrum without consideration of the temperature on the other side of the panel (as is the case with conventional solar panels that operate in the visible spectrum).Note that it is possible to convert heat completely into work, such as the isothermal expansion of ideal gas. However, such a process has an additional result. In the case of the isothermal expansion, the volume of the gas increases and never goes back without outside interference.
