Ampak saj večja teža spet ni tak problem za večji avto. Seveda nebo tolika užitka v vožnji, ampak za recimo avto tipa RR ali S klasa po možnosti s šoferjem to ni taka težava, saj tako že tehtajo čez 2t. Užitka v vožnji sicer nebi bilo ampak to niti ni cilj teh avtomobilov. Za zabavo pa so še vedno najboljši klasićni bencinci.
Pa mogoče so še boljši vzor od lokomotiv podmornice, ki so imele dizelske generatorje, ki so dovajali energijo elektromotorjem ter še akumulatorje za plovbo pod vodo, ko motorji niso mogli delovati. To kombinacijo bi lahko uporabili tud pri avtih plus še možnost zunanjega polnjenja akumulatorjev. Poleg tega poraba generatorja ni toliko pomembna in je lahko bolj navit, ker se večino časa avto tako polni na elektriko preko vtičnice, generator pa samo za dolge vožnje.
Early submarines used a direct mechanical connection between the engine and propeller, switching between diesel engines for surface running, and electric motors for submerged propulsion. This was effectively a "parallel" type of hybrid, since the motor and engine were coupled to the same shaft, with the option to disconnect the engine for submerged operation, and using the motor as a generator to recharge the batteries while on the surface.
True diesel-electric transmissions for submarines were first proposed by the United States Navy's Bureau of Engineering in 1928; instead of driving the propeller directly while running on the surface, the submarine's diesel would instead drive a generator that could either charge the submarine's batteries or drive the electric motor. This meant that motor speed was independent of the diesel engine's speed, and the diesel could run at an optimum and non-critical speed, while one or more of the diesel engines could be shut down for maintenance while the submarine continued to run using battery power. The concept was pioneered in 1929 in the S-class submarines S-3, S-6, and S-7 to test the concept. No other navy adopted the system before 1945 except for the British Royal Navy's U-class submarines, although some submarines of the Imperial Japanese Navy used separate diesel generators for low-speed running.
In a diesel-electric direct drive arrangement, the propellers are driven directly by an electric motor, while two or more diesel-generators provide electric energy for charging the batteries and/or driving the electric motors. This mechanically isolates the noisy engine compartment from the outer pressure hull and reduces the acoustic signature of the submarine. Some nuclear submarines also decouple their reactor room this way, having turbo-electric propulsion driven by reactor steam. Many submarines with diesel and electrical propulsion are mistakenly referred to as "diesel-electric" when they in fact have separately coupled diesel and electric engines.
btw. kako velik pa je 100Kw generator? oziroma a so generatorji enako veliki in težki ali večji kot motorji podobne zmogljivosti?
