I am here today to propose a "perpetual" device. it doesn't make energy, its perpetual in the sense that more energy (specificly electricity) is received that the amount used. Have your heard of the Dyson bladeless fan? well ill post a link for you to read, but ill put all the basic information you need to know here with my proposal that works with the laws of physics.
http://electronics.howstuffworks.com/gadgets/other-gadgets/dyson-bladeless-fan1.htm - note: there is a page before that, but its about the advertisement, absolutely no relavent facts are on that page.
The Dyson fan isn't really bladeless, inside the pedestal there is indeed a fan. "A motor rotates nine asymmetrically-aligned blades to pull air into the device. According to Dyson, these blades can pull in up to 5.28 gallons (about 20 liters) of air per second. " The air then proceeds to flow out of a ramp inside the circle. But that's not what you feel when the fluid flow of wind blows. You feel more than the 20 liters because
"It boils down to physics. While it's true that the atmosphere is gaseous, gases obey the physical laws of fluid dynamics. As air flows through the slits in the tube and out through the front of the fan, air behind the fan is drawn through the tube as well. This is called inducement. The flowing air pushed by the motor induces the air behind the fan to follow.
Air surrounding the edges of the fan will also begin to flow in the direction of the breeze. This process is called entrainment. Through inducement and entrainment, Dyson claims the Air Multiplier increases the output of airflow by 15 times the amount it takes in through the pedestal's motor."
Meaning 1/15 of the normal amount of electricity used in normal fans can influence the same breeze. So what if this fan was facing a wind turbine? (miniature of course, unless the fan where to be enlarged for this purpose) Couldn't it make more electricity than used?
