JAKARTA, KOMPAS.com - While many scientists are busy thinking about solutions to energy-efficient unit but Indonesia also find the fact that many regions in this country are not yet affordable electric service. Dr Taufik, Indonesian professor who works in the U.S. is the one that interested to solve the problem. Not by finding new sources of energy, but by creating a new system with energy sources and technologies that already exist.

"If I was more interested in technology that could be developed so quickly. If I had to wait for tens of years, that's too long. Even better is easy, simple and quick to apply," he said on the sidelines of the International Summit International Scientists Association of Indonesia (I-4) in Jakarta, Thursday (12/16/2010).

Be the DC House he planned program that will be implemented starting in January with his students. Principally, the house uses DC electric current, not AC as it is commonly used.

"The current DC has the advantage of higher efficiency. If the AC current, much energy is wasted during the transfer," he said. With these currents, the efficiency can ditingkatnya from 5 to 10 percent resulting in more power thrifty.

The use of DC current is thought can be more flexible. Energy sources can come from anywhere, such as hidropower, solar panels or wind, according to the potential of each region although it is said that solar panels are the most optimal.

"Even the most powerful, we can transfer energy from humans to plants. For example, people who ride can transfer energy in batteries, which are stored and can be used," said the man who has been teaching in the U.S. for 11 years.

Electrical energy produced from each source will be transferred to the home via cable. Before you get to the house, the electricity generated will pass through a converter that acts to stabilize the voltage that initially up and down according to the ability of the power source to produce energy.

"Well, that's where my expertise," said Taufik who are engaged in electronics, especially the DC converter. He has designed a DC converter that is used for US-owned Abram tanks and F-37 aircraft and recently won a patent for the converter makes.

When electrical energy to the house, there are still things that need to be addressed. In AC systems, each tool will require the same voltage. However, the DC system, the voltage required varies and should be no adjustment.

"We will develop socket also equipped with sensors. With that, the electrical system will suit the needs of each tool," said Taufik describes the solution of problems of this DC system development.

In the early stages, Taufik will develop it on a small scale. "We ujicobakan first at one house, using a suitable energy source. Later, when it's running will be developed with a larger scale," said Taufik.

For example, Taufik explained that later can be developed in such a bus center, a kind of a place to gather energy in a particular community, allowing everyone to share energy sources when one feel deprived.

Estuary is the electrical energy revolution. Energy source that had been conditioned into using DC. Then, the community which is mainly located in areas unaffected by electricity could seek to share power and to meet their needs.

To make it happen, according to Taufik is not difficult. "We do not develop new technologies but use an existing one. Lamp DC, DC refrigerators now also available. So it can be quickly applied," he explained.

Taufik is a professor in the Department of Electrical Engineering California Polytechnic State University in the United States or who is more often called Calpoly. He is engaged in electronics, particularly about DC converter.

He was a man from the Cape region Priuk, Jakarta. Since childhood, he faced power limitations. "Back then still use kerosene lamps. Electricity use from the battery. If the battery runs out we are again watching TV, the screen become smaller, should look more closely," he said with a laugh remembering the experience.

Graduated from Cleveland, Ohio, today, he also helped several universities to obtain accreditation Abet, a prestigious accreditation from the American in the field of engineering education.

DC House project was due to start January will take Indonesia as its pilot project. Tomorrow, he will present his idea in a meeting of the International Summit 2010 International Association of Indonesian Scientists in the electronics cluster.
