This item wasn't made using a 3D printer, but it will help those in less fortunate countries. Kodjo Afate Grikou, a 33-year-old in the African naiton of Togo, used his imagination, talent, and ambition to create the first 3D printer built entirely out of e-waste and scrap metal. He funded his project on the European social funding website ulule this year. The W.Afate project received more than $5,500. The printer cost him only about $100 to build. He hopes members of his community will print things like basic kitchen wares that aren't relatively available in West Africa. He also hopes that the printer will give young people hope and help answer the question "Why is Africa always lagging behind when it comes to technology?" (Source: Hackaday.com)
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
As industrial applications increasingly use process control systems utilizing sensor feedbacks to monitor various operating parameters, energy sources and consumption are becoming major factors of a system.
