====**Echolocation:** This invention is most efficient and useful. This high-tech device uses a sonar-like technology and is designed for the visually impaired. It is a cane that sends sound waves ahead of the person holding it, which senses upcoming objects such as other people, vehicles, or street signs and warns the person holding the cane in a tactile motion through the cane's handle. This is a brilliant design that aims to help the visually impaired to a great extent. It acts as a great safety tool in order to prevent collisions. The basic cane that most visually impaired use today is quite risky as it does not prove to be a very efficient tool. In my view, this is a great invention because I often come across visually impaired people walking with their basic canes trying to cross the road or trying hard to get through a crowded space, and this new device would definitely make it easier and more convenient for them. It is good to see through inventions like these, that people care and are giving more attention to the visually impaired.====

====**Sticking Naturally, Toxin-Free Glue:** This is one of the best examples of biomimicry. Glue is something that used by almost everyone in their everyday lives, school, play, and work. It is very harmful as they are usually filled with toxins that affect not only humans, but also animals and the environment. Researchers at Portland-based Columbia Forest Products developed a super strong glue without the use of any toxins. This design is very good because it is natural and not harmless. It is great to see how this design is mimicking a simple mechanism of mussels, their sticking substance they use to cling to surfaces underwater, to create such a harmless and useful product that is practically used by majority of the people to fix things, or to further create more objects or products. This is a good approach that creates something that is necessary and useful.====

====**Evian Elements, High Speed Train:** This japanese bullet train is one of the fasted trains in the world and is a biomimicry design. This train's design is based on the owl (quietest bird) and the kingfisher (beak). The train is designed with small serrations like that of an owl feathers that reduces the noise that is generated by the train's pantograph. Also, it borrowed an idea of a kingfisher's beak, which allows for the least amount of resistance when the bird dives into water. The train's nose cone is designed in a similar way so that the aerodynamic design reduces the sonic boom that occurs when the train passes from tunnel back into the open air. This train is designed in this specific way to reduce noise pollution. This is a great idea as noise pollution can be a problem to everyone as it can be harmful to their ears.====
