If electric turbos are a thing why cant exhaust gasses be used to generate electricity for the car?

Electric turb os are a type of exhaust gas turb ine that can be used to generate electricity from the exhaust g ases of a car ' s engine . These turb ines work by conver ting the heat energy in the exhaust g ases into mechanical energy , which can then be used to drive a generator and produce electricity . \n \n One of the main advantages of using electric turb os is that they can be highly efficient , conver ting a significant portion of the heat energy in the exhaust g ases into electricity . This can help to reduce the overall fuel consumption of the car , as well as lower emissions . \n \n However , there are also some challenges associated with using electric turb os in cars . For example , they require a significant amount of space and weight , which can impact the overall performance and handling of the car . Additionally , they can be relatively expensive to manufact ure and maintain . \n \n Over all , while electric turb os have the potential to be a useful technology for generating electricity in cars , they are not yet widely used due to these and other challenges . </s>
