If you are a fan of cars and engineering, then this video is likely going to fascinate you. While modern cars pretty much exclusively stick to internal combustion engines or electric motors, cars of the past were a little more experimental in how they were powered. One car featured in the video below ran both on coal gas and gasoline. The car features an onboard coal oven and gas-fan collector.
The designs of these old-era cars also stand in sharp contrast to the modern area of design. Rather than making everything functional and similar in design shape, these old cars are closer to works of art and engineering than they are pleasantries to drive. You can check out the video below to see a survey of a private and pristine automotive collection and a few of the prized engineering jewels housed within.
