Wind Power Generators -- Windmills Annual Output (KWH/year) = 0.01328 (D^2) (V^3) source... Where D^2 is the blade diameter in feet squared, and V^3 is the wind velocity cubed in mph -- this is the year round average wind speed -- see wind maps below. So, a 10 ft diameter wind turbine in 12 mph average winds might produce about (0.01328)(10^2)(12^3) = 2300 KWH/year Note that the energy produced is proportional to the cube of wind speed -- having enough average wind speed is everything in wind turbines. The graph is of the wind energy equation shown above for various wind speeds and turbine blade diameters See also: Solar and WIND water pumping ...
100% American Made. Made in America. Greg Medford is a native Arizonan and an ardent American patriot. He is dedicated to hand-crafting and small-scale manufacturing as a part of the new Small Factory Industrial Rebirth of America. Greg’s early development was deeply shaped by his Mom being 2nd generation Greek immigrant and Dad being from an old Irish/ American family that hails from Massachusetts, West Texas and Arizona. The values of pragmatism, hard work, honesty, love of one’s country, and treating people right were instilled early. His grandpa Ferris Medford was a scrappy West Texas American forged out of the dust and cattle that surrounded him. Greg was part of the augmentation force integrated into the 5th Marines and was a part of ground combat operations in Task Force Ripper in Western Kuwait.
DIY Solar Lamp: Make Your Own Eco-Friendly Sun Jars The principle is simple and seductively clever: solar lights that store energy during the day and release light at night. These can be purchased ready-made in a variety of colors (yellow, blue and red) but they can also be built at home. A simple, less-technical approach involves buying a conventional solar-powered yard lamp and then essentially harvesting it for key pieces to put in a jar. This is simply a way of taking an existing solar lamp design and appropriating its parts to make something more attractive for display around a house or home. A more electronically-savvy individual can take the more complex route and built a solar lamp from the ground up using small solar panels – though the aesthetic result may not be as impressive. Whatever route you choose to go, these are fun and sustainable gadgets that make it easy to go green, automate the process of turning on lights at night and can add some color to your porch, patio, garden or windowsill.

Aliens M41A Pulse Rifle - Fully Functional You look at the replica M41A Pulse Rifle from Aliens, its fully adjustable metal stock and removable magazine, and wonder, Is it real? It looks real. It's the right shape. Well, let us save you the trouble of sending a friend to do the recon that culminates badly in an awkward and humiliating sauna encounter at the gym. It's real, and it's magnificent. This M41A Pulse comes from neither a kit nor Japan. UPDATE: Yes, for those who have inquired, the rifle is a fully-functional prop, whose parts are identical to, and function exactly as the versions the actors used in Aliens.
