Floating Power

From: Magenn Power Inc
Here’s another thing that follows the same general idea as the Flying power from last week. This time they are using lighter then air helium to raise the blimp to over 330 meters above the ground. Like the other ones, it transfers its power to the ground via cables (come on science, invent wireless electricity already). However this one looks to be more stable in the air, considering it’s a blimp, and not a helicopter Detail... (Technology not D.I.Y)

Making and using a solar cooker

By Joe Radabaugh From http://www.backwoodshome.com/articles/radabaugh30.html
It was during those days that I saw my first solar cooker and began the hobby that led to the cooker described in this article. I started out building the most efficient styles I could come up with. Later, while keeping this efficiency, I strove to simplify the building process, the materials needed, and the actual use of the cooker. The cooker is now basically cardboard, aluminum foil, and glass. Yet, because of the design, it is remarkably efficient and durable.
It looks so simple now, but you should realize that this simplicity took years of effort and many accidental breakthroughs. The testing for this cooker is now complete.
What I have included here is a very good starter model that can lead you and your family to a lifetime of enjoyment without threatening your pocketbook. A solar cooker can easily be built for under $10. Detail...
