in Subs they just use Diesels to charge the batterys, thats it, for the electric motor.
Incorrect.
A diesel submarine is a very good example of a hybrid vehicle. Most diesel subs have two or more diesel engines. The diesels can run propellers or they can run generators that recharge a very large battery bank. They can also work in combination, one engine driving a propeller and the other driving all generator. The sub must surface (or cruise just below the surface using a snorkel) to run the diesel engines. Once the batteries are fully charged, the sub can head underwater. The batteries power electric motors that drive the propellers. Battery operation is the only way a diesel sub can actually submerge.
"free recharging stations" are you kidding? I guess the electricity just self generates and shows up at the charging stationsomeone is paying for them, how much of the purchase price is for the "free" charges?
but how about doing a more detailed calculation including the purchase price of the vehicles, maintenance, refueling, etc over a 5 year period? Oh, and you better include the EPA fee for disposing of the hazardous waste battery when it wears out.
The free charging stations are solar powered. Their free lifetime charging cost are included in the price of the car. So are the cost of the lifetime battery warranty & recycling. Also free on the spot loaner car & towing transport for warranty work.
so if you need a charge at night or on a cloudy day---------you just sit on your ass and wait---------wow, what a great deal!
Todays trains use turbines to generate electric power for motion. They don't build diesel electrics any more, do they?
No, it is not cheaper at present. Lithuim batteries are hard to manufacture at present in the size required for automobiles.
And the cost of the Tesla S is not really any higher than many of the high end luxury sedans. Remember, you are dealing with a sedan that does 0 to 60 in under 5 seconds. And is rated higher than the high end Mercedes, BMW, and Audi by Consumer Reports.
However, the battery cost will come down, whether in steps, or a magnitude jump. How many years ago was it that a 60 in. TV cost 10's of thousands of dollars?

People want 60 in. TV's... They also want cars that can go unlimited miles without recharges taking more than just a few minutes.

Not only just posts opinions, he fails to do even the most basic research. One has to wonder what he did in the military that left him with no ability at all to do minimal research.
No it hasnt. your just getting mad. because your wrong and I know the electic motor is far superior to the diesel, they didnt get rid of the transmisson in ships to save weight and you know it. They dont have the start up horsepower at low speeds to move that ship, that the electric motor has. provide a link to prove me wrong. please......
Yeah the can build big diesels. I don't recall saying big diesels were a problem.
the reason that ships use diesel electric power is to save weight, increase manuverability and eliminate the reduction gears and shaft bearings.
also in military ships its sometimes done to reduce the noise signature of the ship to make it harder to detect by sonar.
This topic has gotten so far off track I think it may be time to close it.

true, did I say otherwise? when was the last diesel electric sub built?
Diesel electrics still rule. Gas turbine-electrics were a thing in the 50's, but too loud and uneconomical. Think Chrysler Turbocar.

Actually, the Chrysler Turbine Car was very quiet...it was just too expensive to build. (Turbines are EXPENSIVE.)
