This time we are not talking about solar, wind or any other popularly known renewable source of energy for that matter. Scientists in Brazil have actually made the unbelievable thing – mentioned in above header – a reality as they got into the basics of developing a more effective way to utilize the fibers from pineapple, banana and coconut for the nexgen automotives. These cars will be lighter, stronger and more eco-friendlier as compared to the plastics presently in use.
Leader of the study, Alcides Leão, is of the opinion that the fibers utilized to make the plastics stronger may come from soft fruits like pineapples and bananas. These are called nano-cellulose; it is one of the strongest fibers like Kevlar, famous material used in bulletproof vests and armor. But unlike the Kevlar, which is formed from natural gas or petroleum, the nano-cellulose fibers are wholly renewable.
These types of cars are also heat resistant along with water, disgorged gasoline and oxygen resistant. Similar to the fibers derived from carbon, glass, and other materials, nano-cellulose fibers too can be combined with the raw material usedto produce plastics making it stronger and durable in long run. As per Leão, leaves and stems of pineapple are the most benevolent sources for nano-cellulose when compared to wood. He has teamed up with Sao Paulo StateUniversity in Brazil to make his ambition practically possible.
To develop the ultra small fibers, the scientists slip in the stems and leaves of pineapples or bananas into a device like a pressure cooker. Secondly, they heat up a mixture of some chemicals added to the plants for a specific period developing a smooth material similar to talcum powder. Though huge costs may run up for this process, still it makes the outer part of the car stronger and safer.
The projects is said to be funded by the government of Brazil, Toro Industria,Comercio Ltd, and Pematec along with some other private companies.
