The efficiency is100%only whenT2is zero orT1is infinite. This is not possible since some amount of heat gets rejected to the sink. Since no other process can be more efficient than the processes involved in the Carnot cycle, this cycle is the most efficient. The addition of heat in the ...
Stirling engines had the same theoretical efficiency as the Carnot cycle and the Carnot cycle has the maximum possible theoretical efficiency. I thought to myself, “if these are so great, why are they not being used?” It’s probably the same question that brought you to this page. Other ...
did you know that stars do not twinkle; they only appear to twinkle when seen from the earth’s surface. the stars seem to twinkle in the night sky due to the effects of the earth’s atmosphere. when starlight enters the atmosphere, it is affected by winds in the atmosphere and areas...
namelyCarnot’s Theorem, which puts bounds on the efficiency of a heat engine, based on the absolute temperatures involved. Let’s say you have an steam engine with internal temperature ofTH=200∘C=473KTH=200∘C=473K, and a coolant reservoir that is atTC=40∘C=313KTC=40∘C...
Since unicorn schist is unlikely to appear on the energy scene any time soon and most energy consumers prefer to not freeze in the dark, it should come as little surprise that according to the US EIA’s Annual Energy Outlook, in 2050 we’ll be getting 48% of 31% of our electricity fro...
