Biomimicry- Boxfish Car
Transcript of Biomimicry- Boxfish Car
combining nature and technology Inspiration?
Underwater World! The boxfish conserves its strength by moving while consuming the least possible amount of energy. Car-making process Biomimicry The Boxfish car includes many traits of the boxfish including:
the overall appearance (face-body proportion)
the rigid yet light material of the car frame
a complex engine and overall design that allows it to be extremely fuel efficient The yellow boxfish, Ostracion cubicus Found primarily in tropical areas within the aquatic ecosystem.
They like areas where coral reefs are located.
In rocky waters as well as patches of sand and sea grass.
Specific locations are the Hawaiian and Tuamoto islands
Waters off the coast of the Red Sea and East Africa. Eat Autotrophs, such as algae.
Heterotrophs like other small fish, crustaceans, invertebrates, and mollusks ("Polka-dot boxfish").
Through their bodily processes, they fertilize the plants in the water around them through their waste.
But hunted and serve as food for larger fish. The skin of the boxfish consists of numerous hexagonal bony plates which provide maximum strength for the fish while reducing the amount of weight the fish carries.
Due to the shape of the plates, this lack of weight does not sacrifice protection. Sold in souvenir shops
Toxins ... suicide?
Rigid structure to protect itself, as collisions often happen between coral reefs.
Helps to move in confined spaces when searching for food and that requires great maneuverability
The fish takes advantage of its light weight to move quickly and efficiently through the water.
The angular structure of the fish conserves energy for the fish because it is both aerodynamic and streamlined The Boxfish Car’s aerodynamic shape creates less air turbulence when it is driven, therefore resulting in better gas mileage. Thus, one major accomplishment of this car is that it has the least air friction in the current automobile industry. This four seat vehicle has a drag coefficient of 0.19, which is far better than that of Honda’s two seat vehicle that currently has the lowest drag coefficient on the market (Phenix, 2007). The Boxfish Car has a strong and lightweight frame that further ensures higher mileage and a safer drive (Wilssense, 2005). As a result of its innovative shape and improved car frame, the Boxfish Car has better mileage than existing high mileage per gallon vehicles. There are several well known hybrid cars in the U.S. car market. The Toyota Prius is the most fuel efficient and most well known hybrid car getting approximately 50mpg ("Prius '10," 2010). The boxfish car; however, gets up to 84mpg on the highway, which is substantially higher than that of the current existing hybrid models (Wilssens, 2005). The biggest competition for the Boxfish car is the increasing number of electric cars being developed and released. The 2011 Chevy Volt is being highly publicized and recently won the "2011 Motor Trend Car of the Year®" award which is one of the most prominent honors in the automotive industry ("2011 volt"). According to the EPA, the Volt, which will be released in 2011, will get 60mpg using both its electric and gas based system (Murphy, 2010). In four hours, the Chevy Volt can be fully charged for about $1.50 and able to travel around 45 miles (Murphy, 2010). During the 45 miles, the car can reach a maximum of 168mpg, but once the gas motor kicks in, it drops to 37mpg (Murphy, 2010). When running on its battery, the car produces zero emissions which is extremely environmentally friendly. Similar to the Volt, the Nissan LEAF is being released soon but it is a 100% electric car without a tailpipe. It will be able to travel 100 miles with a full charge, which takes about seven hours ("Nissan leaf electric"). The Nissan LEAF does not have a backup motor and is therefore completely emission free. Although electric cars need improvement, they provide a clean way to drive and will soon be a major competitor for other hybrid cars as well as the Boxfish Car. The Boxfish car uses “AdBlue” to further reduce emissions. Depending on the engine’s operating status, a clear, non-toxic, and safe to handle aqueous urea solution called “AdBlue”, is sprayed into the exhaust system ("Mercedes-benz bionic car," 2008). The reaction converts the nitrogen oxides into nitrogen and water. AdBlue, even at a low dosage, is also proven to be able to ensure long refill periods, decreasing the number of times one will have to refill his or her tank in a year ("What is adblue," 2009). The car also comes with a special filter which helps to clean the diesel gas as well as the emissions before they are released. A diesel engine is also beneficial to a car because it will last much longer than a gas engine, This is due to the fact that diesel fuel is much friendlier to an engine than regular gas. (Richard, 2005). Unlike the expensive Hydrogen Fuel cells that some other cars of the future come with, diesel can be bought anywhere (Richard, 2005). Another benefit of Diesel engines is that they produce very little carbon monoxide, which is a leading contributor to pollution. ("Daimlerchrysler showcases 70," 2005).
