The first thing that readers should know is that Chem-E-Car is a college competition that happens on an annual basis among those students who are interested in chemical engineering. According to the official rules set for this competition, all participants are required to design their small-scale automobiles operated by different chemical meals, along with a detailed poster that described their individual research.
In this competition, students also need to drive their car designs in some fixed distance down a special wedge-shaped course to demonstrate and prove their capabilities. Another important part of this competition is that students need to hold a specific payload of water, and these basic requirements are always revealed to all participants only 1 hour before the competition starts. Besides, the size of their car designs is not allowed to exceed pre-set specifications and they should operate by using only green methods that don’t release any waste or pollution in the form of different gases or liquids, including the exhaust.
All car designs also need to have specific dimensions, and those students who succeed to with this competition always receive different awards according to their place. For instance, the evolution of their Chem-E-Car designs can be tracked from the first attempt based on the exothermic reaction of HCL and simple baking soda. The latter one is replaced in the car that has its special valve at the bottom, and when this valve is open, a particular reaction is initiated to liberate CO2. The liberated CO2 creates the necessary pressure gradient, and this pressure pushes a gear on back-wheels to move this car design.
Another interesting design that allows people to track the evolution of such designs is all about a reactor vessel, but it comes with a special turbine on the top of its outlet stream. Its creators plan to use a precise acid-metal reaction to liberate enough hydrogen gas. This is when a highly-pressurized gas escapes via a pre-designed turbine mechanism that is mounted to this car design. Its axle is connected to its gear wheel outside of this vessel to a turbine wheel.
Its gear wheel works with the other gear wheel on its main axle, and as a gas turns its turbine wheel, a gear start turning this car design forward. The main reason why this Chem-E-Car design was improved is that it had a it had slow reaction to produce the necessary gas.
