Prior Attempts
The patent above describes a machine that would not only cool the apparatus of the surrounding atmosphere, but also scrubbing certain gases so that it removes any harmful or odorous gases in the surrounding atmosphere. The product was developed for mining expeditions, and it cleansed and cooled the mines by using a basic water to cancel out the acidity of the emitting gases. While this design worked in the short run, it didn’t eliminate the acidic water left over or have a way to transfer such water. With a product that could eliminate the gases through a filter, it would eliminate the process of storing and replacing the water, only have to replace the filter, and also giving revenue to the selling company.
The patent above is designed for the exhaust from houses, and allows the elimination of “dirty gas,” gases with water and dust collected in them. It has multiple processes of eliminating the dust and water, and getting rid of that excess water by draining it down the house and dust by collecting it through a special filter. While this product does decrease the danger of the gases released from the houses, it still doesn’t solve the overall issue of the potent gas being released.
The patent above describes a emission filter that reduces the amount of carbon emitted from automobiles, using chemicals like soda lime, manganese, oxide of copper, and a “closely woven nylon-based fiber” developed by Eastman Kodak Company. However, as the product was ahead of its time when developed, the filter has several flaws that can limit its use. The filter can’t be placed on all types of vehicles, due to the fact the filter can only slightly adjust and it is made for automobiles, vehicles powered by an engine that can house two or more people. So vehicles like mopeds, motorcycles, and all terrain vehicles couldn’t use this product to reduce emissions. It also couldn’t reduce emissions for lawn equipment that also uses internal combustion engines to power the tool.
Taking from the shortcomings of the products shown above, we intended to develop a smaller, low-profile scrubber that can be affixed to a variety of off-road vehicles, reducing the amount of emissions without any harmful byproduct as a result. In creating this product, the amount of annual emissions can be greatly reduced, benefitting those who have been affected and are susceptible to the harmful effects of air pollution.
