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.

Near 100% is NOT 100%.

The inventor didn't say he could get NEAR 100%. He stated flat out that it could achieve 100% efficiency. He acutally insinuates that his heat engine can exceed the carnot efficiency.

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.

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.
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.

Moderator's note: I am locking this thread as it has gone off topic, it was originally a discussion of electric vehicles. The current discussion is going nowhere.
