Pollution is a problem that many people have tried to solve.
There have been numerous designs that are supposed to reduce the amount of factory pollution, but so far we have not found a design that works. In my research on this subject I have found a design that I think, with a few modifications, will be a huge hit. The design is a car that has both an internal combustion engine and an electric motor. This car has been named a hybrid car. The car uses the internal combustion engine to start the car an once a certain speed is reached the car switches into the elctric car mode.
