Genuine question why don't we spin up a turbine with the exhaust gas that runs a generator and that runs electrical assist / charges batteries

@S.ASmith Interesting - Ill look it up. It was one of those things that seemed so obvious I thought I was being really stupid asking the question.

@Kelle128 "makes an extra boost for the engine which creates more power." NO IT DOES NOT. The additional fuel you can add as a result of the increased volume of O2 is what increases the power. NOT the turbocharger.

THE STEAM ENGINE WAS INVENTED IN 1712 and its still in use today in nuclear aircraft carriers...!!! - 312 years...!!! OK apples and pears - the steam turbine was invented in 1884 and that is EXACTLY what is used in Nuclear carriers - 140 years Somethings we just got right the first go.

@vylbird8014 which sucks the energy from the engine instead of recovering wasted energy from the exhaust gasses. Making the engine L:ESS efficient not MORE efficeint.

@onupeer5771 I guess until the advent of HVDC / AC car systems it was pretty useless - you are going to get wildly variable voltages just like regenerative breaking, you need advanced electronics to harness that.

@vylbird8014 Efficiency is absolutely everything for fleet cars, delivery vans and trucks

@jimmydesouza4375 Read down 2 comments - you terrible excuse for humanity

@ZeroXSEED YES because you are using a smaller engine if "same horsepower AND peak power rpm" V naturally aspirated so you have less friction.

@Stef.Cata051 Found it - thats cool

@igornoga5362 - Im really pleased I asked this question - Ive had some great replies about things I was totally unaware of. EDIT "The Turbo Compound delivers it's energy directly mechanically to the crankshaft with the help of gears and fluid couplings. The PRT's (Power Recovery Turbines) deliver 20% more power to the engine from the "waste" energy of the exhaust gases." 20% thats a lot. Obviously and aircraft engine is a high RPM almost constantly so ther eis a lot to recover.

@ClockDev OH cool thanks Illgo look for that
