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. One thing I noticed right away about my property is that most of the time, the wind is blowing. More details on this project and my other alternative energy projects including my home-built solar panels, and my home-built biomass gasifier can be found on my web site.

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. That's huge considering a working quantum computer would be the kind of thing that truly moves the ground beneath our feet. But first they have to build one. The idea of quantum computing was introduced in the early 1980s by physicist Richard Feynman, and the field is still very much in its infancy. The quantum analog for the bit is called a qubit.

Ready to Rock - a "condensed" version shown for the photo, with a 3/4 hp generator, held by the inventor, Doug Selsam. Here are the blades of a 20 inch diameter turbine, that produces about half a kilowatt. They will be mounted on a shaft that projects for a long distance forward, and backward, at an angle from horizontal, so that the wind encounters the rotors like a stairway. Each additional rotor brings more power. The combined output from all these small rotors really adds up. The New Turbine is flown in Tehachapi, mounted to a Tower by Brent Scheibel, of General Electric Wind and owner of WindTesting.com Well, it's up and running, with data being logged. Brent Scheibel, WindTesting.com, His wife, Teri, with their dog Ezra, and Doug Selsam, windmill is seen in background The Sky Serpent, flying alongside Brent Scheibel of Windtesting.com's SWWP 900 watt turbine. Row after row of clean-turning turbine blades adorn the landscape... pretty cool.
How to build My 50 Dollar Greenhouse & The Door Garden
First off – you really can build this thing very cheaply, but to do so you have to recycle, freecycle, and scrounge. If you just go out and buy new everything it will probably cost over $200 – still not bad all in all.This Article is featured in Jan 2010 issue of Birds and Blooms Magazine!Want to find out if this thing works before you read all this? Read 6 months in the Greenhouse first.Want to see what happens when a few inches of wet snow accumulates on this? Collapse!Building the Greenhouse Doors is addressed in a separate article – isn’t this enough for one weekend? My $50 Greenhouse Welcome Stumbleupon Gardeners! Materials list Construction Steps Hind Sight – What I would do differently The planning is over and construction on my hoop house greenhouse has begun. After some research I’ve decided to build the structure of the hoop house out of 20 ft. joints of three quarter inch PVC plumbing pipe. If your Greenhouse is too Flat it will collapse!

Homemade Lotion Recipe - How to Make Your Own Lotion
If you are still using the cancer-in-a-bottle store bought lotion on yourself or your family, there are super easy natural alternatives! In fact, this recipe is incredibly simple to make and all the ingredients are available here. It only has three basic ingredients and literally takes ten minutes to make! You can customize your lotion to your skin type and desired scent, and you can even make it for baby (calendula and chamomile…) There are endless variations, but some of my favorites are: Calendula and Chamomile for babyRosewater and Almond OilPeppermint, Wintergreen, and Ginger for sore musclesCoconut and Calendula for faceMint and green teaLavender and vanilla I’ve included my basic recipe below. NOTE: This is an improved recipe since many people were having trouble getting the temperatures exactly right to get the lotion to emulsify (as per the comments below). Organic Homemade Lotion Basic Ingredients: Note: All ingredients and many essential oils are available here.

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 , In earlier trials, the researchers used different alloys that achieved full spectrum responses but involved very high production costs. The Lawrence Berkeley breakthrough represents just one path to increasing the efficiency and lowering the cost of solar cells. In the meantime, you could just turn any metal surface into solar panels with photovoltaic spray paint . [Photo: Norby /Flickr]
