Abstract

This project is based on how to transmit electrical power without wires, using solar energy as source. The power is transferred wirelessly through an inductive coupling method. With this new discovery, we no longer need complicated with the cable passing around us, with Power without Wires (Wireless Electricity) we can use our electronic equipment such as TV, MP3 Player, HiFi Headset; everything works without the use of batteries or electrical wiring. In fact, mobile devices such as laptop batteries, mobile phone, or digital camera filled automatically, so once you enter the house, of course without having to plug in the cable. The project is offer to study and fabricate wireless power transfer by using inductive coupling. Experiments have been conducted and the wireless power transfer using inductive coupling can be transfer energy up to 10 cm.

Abstract

 This paper presents an analysis of the wind speed characteristics in Perlis, Northern Malaysia for the year of 2006. The characteristics consist of daily, monthly and annual mean wind speed. The Weibull distribution function is applied to analyze the wind speed characteristics and used to calculate the wind power generation potential. Potential of wind power generation is observed and analyzed during 24 hours (9th March 2011). The analysis result of monthly mean wind power and energy density show that the early (January to march) and the end (December) of year have a high wind power and energy potential, but the middle of year they are very low, it is necessary to develop  a special wind power generation capable of harnessing the little wind resource available in Perlis. Observation during 24 hours (9th March 2011), for a 24 V wind power generation gives 10% of its total output voltage.
