The discussion centers around the viability and implications of electric vehicles (EVs), including their environmental impact, energy efficiency, and the potential need for banning them. Participants explore various aspects such as battery technology, power generation methods, and the future of transportation, with a focus on theoretical and practical considerations.
Participants express multiple competing views regarding the future of electric vehicles, the efficiency of various energy sources, and the implications of nuclear power. The discussion remains unresolved, with no consensus reached on whether electric vehicles should be banned or the best path forward for transportation.
Participants highlight limitations in current battery technology, the efficiency of power generation methods, and the complexities of transitioning to alternative energy sources. There are unresolved questions about the long-term viability of both electric and hydrogen vehicles, as well as the environmental impact of nuclear energy.
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.
