How I built an electricity producing wind turbine
Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the terrible light pollution found near cities of any real size. I found a great piece of property.

How It Would Work: Creating a Quantum Computer
Silicon semiconductors have taken us a dazzling distance along the computing road. But even if they continue unabated to get faster and more powerful (and it's growing more difficult to make that happen) there's a limit to what classical computing can do. The next real game-change in computing is quantum--tapping the quantum mechanical properties of materials to process information in ways that will make today's biggest and baddest super computers look like pocket calculators. And for the first time scientists, at places like IBM, are moving beyond just theorizing about them to actually envisioning how a finished quantum computer would work.

How to eat wild stuff and not get poisoned
Let's play pretend for a moment. Are you with me? Let's pretend you can't go down to the supermarket for food to eat. In fact, let's pretend that there is not a supermarket for one hundred miles in any direction, and you don't have any food with you. In this pretend land, you are stranded in the wilderness.
Scientists Develop Affordable Solar Panels That Work In The Dark
It's about damn time, don't you think? Scientists at Lawrence Berkeley National Laboratory announced Wednesday that they have been able to confirm a new high-efficiency solar cell design that utilizes nearly the entire solar spectrum. Translation: They figured out a way to make solar panels generate electricity in the dark. CleanTechnica says ,

International Ground to Air Signal Codes
International Ground-to-Air Signal Codes You can lay out these symbols using strips of fabric, pieces of wood, stone, or any other available material. Try to make as big a color contrast as possible between your symbol(s) and the surrounding terrain. Symbols should be at least 8 feet in height or longer. Take care when constructing these symbols so that they can't be confused.
Rules of Thumb: Ingenious Hand-Held Digital Tape Measure & Dornob
The history of measurement has come full circle, from body-based units to abstracted quantifiers … and now back again to the basics. From lengths and widths to volumes, this set of finger-mounted devices is designed to let the user measure anything, store that data, calculate results and more. Wooden sticks gave way to wood-and-metal rulers and measuring tapes, which in turn were replaced over time by higher-technology digital tools for fine-tuned measurements. Still, how often do you find yourself needing precision down to the very last millimeter or hundredth of an inch in daily life, as a designer or otherwise?
