Tesla Coil really can generate music

A Tesla coil is a type of resonant transformer circuit invented by Nikola Tesla around 1891. It is used to produce high voltage, relatively high current, high frequency alternating current electricity. Tesla experimented with a number of different configurations and they consist of two, or sometimes three, coupled resonant electric circuits. Tesla used these coils to conduct innovative experiments in electrical lighting, phosphorescence, x-ray generation, high frequency alternating current phenomena, electrotherapy, and the transmission of electrical energy without wires.

Tesla coil circuits were used commercially in sparkgap radio transmitters for wireless telegraphy until the 1920s, and in electrotherapy and medical devices such as violet ray (although Tesla circuits were not the first or the only ones used in spark transmitters). Today their main use is entertainment and educational displays. Tesla coils are built by many high-voltage enthusiasts, research institutions, science museums and independent experimenters. Although electronic circuit controllers have been developed, Tesla's original spark gap design is less expensive and has proven extremely reliable.

World Toilet Crisis

According the U.S. State Department, the World Health Organization, and UNICEF, the world's greatest infectious killer is not malaria, AIDS, or TB but poop. An estimated 2.6 billion people, about 40% of the world's population, including 1 billion children, have no access to toilets of any kind and must practice open defecation. The result is a continual pandemic of intestinal afflictions that kill 2 million people a year.

Automatic Faucet - sensor tap

Just as my note, for airport project, it is suggested for the toilet to use sensor tap or automatic faucet. Currently this is the trend for other airport even in Asia as airport a gateway to the country and also spread of diseases such as H1N1.

Below is the description and advantages of sensor tap:-

Definition
An automatic faucet (sometimes called a sensor faucet) is a faucet with a hands-free mechanism for opening and closing its valve. The use of such faucets is mainly confined to public washrooms where they are an important tool for conserving water and mitigating the spread of germs.

How it work
An automatic control for a kitchen or lavatory faucet can significantly reduce water consumption through intermittent operation. Automatic faucets do not need many functions that ordinary faucets need, they need only an operator.

Operating the automatic faucet reduce the result in wasted water between the time that a hand moves from lever to the next object or task at hand to a bar of soap, a pot to fill with water, or a dish for rinsing.


Advantages
Sensor or automatic faucets have the advantage of shutting off automatically after a hand wash therefore cutting down on water waste. This waste is also a concern for people who care for the environment. When installed in home, sensor faucets alleviate the need for parents to ensure that children have turned off taps. Sensor faucets can benefit elderly people or those suffering from arthritis since there are no handles to twist or pull.

Economically, sensor faucets use less water resulting in direct savings on your water bill. In a kitchen setting, they automatically shut off after you have used the correct amount of water for rinsing a pan or washing an apple which also eliminates the worry of a sink overflowing


The main disadvantage of automatic faucet is costly.


Green Building Certification
For green building specification, automatic faucet is best solution to get the most water saving as soome Green Rating tools such as LEED have specify that the faucet water flowrate for baseline design is 0.5 gallon per minute.

For information, the point for water efficiency in green building certification is depend on the saving of water which is the comparison of Proposed Design and Baseline Design.

This method also apply to the Energy Optimization performance (percentage saving between Proposed Design and Baseline Design).

Salam Ramadhan, bulan yang penuh barakah.

Salam Ramadhan, semoga tahun ini lebih baik dari tahun sebelumnya.

Bergembiralah dengan kedatangan bulan Ramadan. Rasulullah saw. selalu memberikan kabar gembira kepada para shahabat setiap kali datang bulan Ramadan, “Telah datang kepada kalian bulan Ramadan, bulan yang penuh berkah. Allah telah mewajibkan kepada kalian untuk berpuasa. Pada bulan itu Allah membuka pintu-pintu surga dan menutup pintu-pintu neraka.” (HR. Ahmad).

Salafush-shalih sangat memperhatikan bulan Ramadan. Mereka sangat gembira dengan kedatangannya. Tidak ada kegembiraan yang paling besar selain kedatangan bulan Ramadan karena bulan itu bulan penuh kebaikan dan turunnya rahmat.
