Customer need, committed though. But, the hiccups and process gaps, must be catastrophical to my team if at all I start. Too many loop holes to fall through, and hence risks are more. Being a hardcore Mechanical Engineer, the non compliance must not be established as part of the system....
DIY Solar Garage: Welcome! In this Instructable, I'd like to show you how I installed my own grid-interactive solar array, so that you can too! To start with, this is a "Grid-Tie" or "Utility-Interactive" solar system. That means that I'm WORKING WITH m
Not Your Average Save Energy Advice: ***Shameless Self-Promotion*** Most of what I write isn't relevant to Instructables. My main blog is here: biodieselhauling.blogspot.com **End Digression... On to the Good Stuff** Everyone has a reason t
Commercial applications for Oil-Free turbomachinery are slowly becoming a reality. Micro-turbine generators, highspeed electric motors, and electrically driven centrifugal blowers are a few examples of commercial products available in the marketplace today. Gas foil bearing technology makes most of these...
