Flying Wind Generators Flying wind generators are the future of wind energy. This article talks about the replacement of wind turbines for “windmills in the sky”. Instead of using the current wind turbines‚ Bryan Roberts‚ and engineer at University of technology in Sydney‚ Australia‚ decided to fly wind turbines into the jet stream 15‚000 to 45‚000 feet into the sky with winds up to 200 miles per hour. With 600 of these producing 20 megawatts each could power two Chicago sized cities. The

Calculating generator reactancesPower topic #6008 | Technical information from Cummins Power Generation Calculating generator reactances > White paper By Timothy A. Loehlein‚ Technical Specialist-Electrical Generator reactances are used for two distinctly different purposes. One use is to calculate the flow of symmetrical short circuit current in coordination studies. A second use for generator reactances are in specifications that limit the sub-transient reactance to 12% or less in order

HUMAN POWERED GENERATORS A generator can also be driven by human muscle power‚ for example‚ in field radio station equipment. Human powered direct current generators are commercially available‚ and have been the project of some DIY enthusiasts. Typically operated by means of pedal power‚ a converted bicycle trainer‚ or a foot pump‚ such generators can be practically used to charge batteries‚ and in some cases are designed with an integral inverter. The average adult could generate about 125-200

On Constructing a Market Consistent Economic Scenario Generator Ebba K. Baldvinsdóttir & Lina Palmborg March 4‚ 2011 Abstract Recently the insurance industry has started to realise the importance of properly managing options and guarantees embedded in insurance contracts. Interest rates have been low in the last few years‚ which means that minimum interest rate guarantees have moved from being far out-of-the money to expiring inthe-money. As a result‚ many insurance companies have experienced

Title: Measuring the speed of sound. Research question: How to determine the speed of sound by using the relationship between the frequency of the signal generator‚ f and the length of air column in the tube‚ l . Variables: Manipulated | Frequency of the signal generator‚ f | Use different frequency of signal generator which are 1000Hz‚ 1400Hz‚ 1800Hz‚ 2000Hz‚ 2500Hz‚ 3000Hz and 3600Hz. | Responding | Length of air column in the tube‚ l (±0.5cm) | Measure the

1. Motors use the effect of forces on current-carrying conductors in magnetic fields Discuss the effect on the magnitude of the force on a current-carrying conductor of variations in: The strength of the magnetic field in which it is located • The magnitude of the force is proportional to the magnetic field strength. Thus‚ an increase in magnetic field strength will cause an increase in the force on the wire and a decrease in magnetic field strength will cause a decrease in force on the

What is sound? Sound is a wave‚ a pattern—simple or complex‚ depending on the sound—of changing air pressure. Sound is produced by vibrations of objects. The vibrations push and pull on air molecules. The pushes cause a local compression of the air (increase in pressure)‚ and the pulls cause a local rarefaction of the air (decrease in pressure). Since the air molecules are already in constant motion‚ the compressions and rarefactions starting at the original source are rapidly transmitted through

1) The marketing department can use the operational CRM technologies of a list generator‚ campaign management and cross-selling and up-selling. List generators compile customer information from a variety of sources and segment the information for different marketing campaigns. List generators provide the marketing department with a solid understanding of the type of customer it needs to target for marketing campaigns. Campaign management systems guide users through marketing campaigns performing
