The forum discussion centers on the viability of electric vehicles (EVs) and the implications of their widespread adoption. Participants argue that the current battery technology limits EVs' effectiveness for long-distance travel, while others highlight the efficiency of power stations in generating electricity compared to internal combustion engines. The conversation also touches on the potential of hydrogen fuel cells and the need for improved infrastructure to support both EVs and hydrogen vehicles. Ultimately, the consensus leans towards the necessity of transitioning to more efficient energy sources, particularly nuclear power, to support the electrification of transportation.
PREREQUISITESThis discussion is beneficial for automotive engineers, energy policy makers, environmental advocates, and anyone interested in the future of sustainable transportation solutions.
sr241 said:second law states that "It is impossible for any system to operate in such a way that the sole result would be an energy transfer by heat from a cooler to a hotter body." So more than 100% efficiency is impossible, however it does not states near 100% efficiency is impossible.
Theoretical limit of Carnote efficiency for IC engines can be overcame by injecting water for cooling by using this method even 100% efficiency is possible.
Both of these conditions are impossible to achieve. Th cannot be infinity; Tc cannot be 0 K. So 100% efficiency is impossible, as others have been saying.sr241 said:for 100% Carnot efficiency you either need T_hot to be infinity or T-cold to be 0 kelvin. if you have theoretical support against the above said then I will appreciate you.
