Wireless electric trams at Seoul Amusement Park begin full operations.
Photo by Hyung-Joon Jun IMMEDIATE RELEASE Wireless electric trams at Seoul Amusement Park begin full operations. KAIST’s On-Line Electric Vehicle (OLEV) becomes an icon of green technology, particularly for young students who aspire to transform their nation into the “vanguard of sustainability.” Seoul, South Korea, July 19, 2011—As young students wrap up their school work before summer vacation in late July, Seoul Grand Park, an amusement park located south of Seoul, is busily preparing to accommodate throngs of summer visitors. Among the park’s routine preparations, however, there is something new to introduce to guests this summer: three wireless electric trams have replaced the old diesel-powered carts used by passengers for transportation within the park. The Korea Advanced Institute of Science and Technology (KAIST) and the city of Seoul held a ceremony this morning, July 19, 2011, to celebrate their joint efforts to adopt a green public transportation system and presented park visitors with the three On-Line Electric Vehicles (OLEVs), which will be operated immediately thereafter. Approximately one hundred people, including science high school students across the nation, attended the ceremony and had a chance to ride the trams. KAIST unveiled the prototype of an electric tram to the public in March 2010, and since then it has developed three commercial trams. The Korean government and the institute have worked on legal issues to embark on the full-scale commercialization of OLEV, and the long awaited approval from the government on such issues as standardization of the OLEV technology and road infrastructure, regulation of electromagnetic fields and electricity safety, and license and permits for vehicle eligibility, finally came through. The On-Line Electric Vehicle (OLEV) is no ordinary electric car in that it is remotely charged via electromagnetic fields created by electric cables buried beneath the road. Unlike other currently available electric cars, OLEV can travel unlimited distances without having to stop to recharge. OLEV also has a small battery onboard, which enables the vehicle to travel on roads that are not equipped with underground power cables. This battery, however, is only one-fifth of the size of a conventional electric vehicle battery, resulting in considerable savings in the cost, size, and weight of the vehicle. The OLEV project was initiated in 2009 as a method of resolving the battery problems of electric cars in a creative and disruptive way. KAIST came up with the idea of supplying electricity directly to the cars instead of depending solely on the onboard battery for power. Since then, the university has developed core technologies related to OLEV such as the “Shaped Magnetic Field in Resonance (SMFIR),” which enables an electric car to collect the magnetic fields and convert them into electricity, and the “Segment Technology,” which controls the flow of electromagnetic waves through an automatic power-on/shut-down system, thereby eliminating accidental exposure of the electromagnetic waves to pedestrians or non-OLEV cars. According to KAIST, three types of OLEV have been developed thus far: electric buses, trams, and sport utility vehicles (SUVs). The technical specifications of the most recently developed OLEV (an electric bus), the OLEV research team at the university said, are as follows: · Power cables are buried 15cm beneath the road surface. · On average, over 80% power transmission efficiency is achieved. · The distance gap between the road surface and the underbody of the vehicle is 20cm. · The OLEV bus has a maximum electricity pickup capacity of 100kW. · The OLEV bus complies with international standards for electromagnetic fields (below 24.1 mG). The eco-friendly electric trams at Seoul Grand Park consume no fossil fuels and do not require any overhead wires or cables. Out of the total circular driving route (2.2km), only 16% of the road, 372.5m, has the embedded power lines, indicating that OLEV does not require extensive reconstruction of the road infrastructure. The city government of Seoul signed a memorandum of understanding with KAIST in 2009 as part of its initiatives to curtail emissions from public transportation and provide cleaner air to its citizens. Both parties plan to expand such collaboration to other transportation systems including buses in the future. KAIST expects the OLEV technology to be applied in industries ranging from transportation to electronics, aviation, maritime transportation, robotics, and leisure. There are several ongoing international collaborative projects to utilize the OLEV technology for a variety of transportation needs, such as inner city commute systems (bus and trolley) and airport shuttle buses, in nations including Malaysia, US, Germany, and Denmark. # # # More information about KAIST’s On-Line Electric Vehicle can be found at http://olev.co.kr/en/index.php.

OLEV Safety Confirmed by International Standards
On September 19, KAIST announced that the electromagnetic (EM) field levels of its online electric vehicle (OLEV) measured in June and September of this year demonstrated verification of its safety. Last June, the EM field level of OLEV installed at the Seoul Grand Park was measured by the Korea Research Institute of Standards and Science (KRISS) to test its harmfulness to human. The results were 0.5 ~ 61mG which is within the national and international standards of 62.5mG. KRISS measured EM field levels on 22 spots on the side of and at the center of OLEV at a fixed distance (30cm) but variable heights (5cm~150cm) according to the national standard of measurement methods for electromagnetic fields of household appliances and similar apparatuses with regard to human exposure (IEC 62233). In addition, another testing took place on September 13 following a request by National Assemblywoman Young-Ah Park, a member of the National Assembly’s Education, Science and Technology Committee, who has raised an issue on the safety of OLEV. This testing session was held by EMF Safety, Inc., an institution designated by Park, and it tested the EM field level of the same OLEV train that was tested in June. As a result, the September measurements were well within the national and international standards with 0~24.1mG. The test was conducted under the presence of third party to produce a fair and objective result. As reference, the EM field level results are well within the American IEEE electromagnetic field standards of 1,100 mG. The September measurements were produced by Park’s recommendation of following the criteria specified in the measurement procedures of IEC 62110, “Electric and magnetic field levels generated by AC power systems to public exposure,” which were 15 measurements at a fixed 20cm distance at the side of and from the center of OLEV with variable heights of 50cm~150cm.

"Our addiction to oil is the major cause of global warming."
Joongang Daily, one of the major newspapers in Korea, interviewed Professor John Spengler from Harvard University, an internationally renowned scholar in environmental science, who visited Korea for a conference. He mentioned KAIST’s online electric vehicle (OLEV) during the course of interview. The paper interviewed him on a wide range of environmental issues, and below is a translation of the original Korean article. For the Korean article, please download the attached picture file. “Our addiction to oil is the major cause of global warming.” Interview with Professor John Spengler from Harvard University—he is an internationally renowned scholar in environmental science. By Chan-Soo Kang, Joongang Daily September 3, 2010 “The oil spill in the Gulf of Mexico by British Petroleum (BP), a multinational oil company, took place against the backdrop of our addition to oil,” said Professor John Spengler (66 years old) from Harvard University on September 2. “The fact that we are addicted to oil means we are obsessed with mobility as well. Throughout the history of mankind, there has never been the time when we move from one place to another as frequently as today and are dependent on fossil fuels as much as today.” Visiting Korea to attend a conference co-sponsored by International Society of Exposure Science (ISES) and International Society of Environmental Epidemiology (ISEE) that was held at Coex in Seoul from August 28 to September 2, he gave his speech at plenary talks of the conference on the a topic titled, “Our health is our planet.” Professor Spengler is an internationally well-known expert in the research of indoor air pollution and environmental exposures of chemical compounds. At the conference, he mostly talked about an ecological catastrophe resulted from the explosion of an oil rig operated by BP in the Gulf of Mexico. He pointed out, “It’s been a problem that oil companies are more willing to take risks of exploring dangerous places to obtain oil as the demand for oil has increased. Excessive oil consumption cannot help but lead to global warming.” “Particularly,” he said, “the unusual climate events, frequently happening in recent years, including severe heat wave and drought in Russia this summer, are somewhat expected to occur by weather forecast models. However, it seems that the extreme weather patterns are taking place more frequently, and accordingly, we are facing more severe effects of weather conditions.” Professor Spengler emphasized that “We should change our diet and lifestyle to reduce the stress put on our ecosystem, such as getting protein from vegetables rather than from fish or meat and having a habit of curtailing energy consumption.” “While I’m here, I have a chance to see an online electric vehicle (OLEV) developed by KAIST. If this technology is applied, we can reduce environmental problems as such,” he assessed the development of OLEV. He also said that “the State of Utah in the US has expressed its intention to adopt the OLEV technology.” With regard to his research focus on indoor air pollution, Professor Spengler said, “We are having problems like “New House Syndrome” because we try to build a house with cheap materials. Governments should set a standard and control pollutants released from building materials in order to reduce risks resulted from indoor air pollution.” He argued, “In the early 1990s, when the Irish government introduced an enhanced regulation of air pollution in Dublin, the mortality rate of the city in that winter dropped dramatically.” “It’s been proven that as fine particle pollution gets worse, more patients with cardiovascular diseases die. Therefore, we need to make efforts to reduce the air pollution.” “Compared with other nations,” Professor Spengler estimated Korea as a nation that “definitely improved its air quality by introducing buses with a Compressed Natural Gas (CNG) engine to its public transportation system.” (End)

The thermal fluctuation and elasticity of cell membranes, lipid vesicles, interacting with pore-forming peptides were reported by a research team at KAIST.
A research team from KAIST, consisted of Sung-Min Choi, Professor of Nuclear and Quantum Engineering Department, and Ji-Hwan Lee, a doctoral student in the Department, published a paper on the “thermal fluctuation and elasticity of lipid vesicles interacting with pore-forming peptides.” The paper was carried by Physical Review Letters, an internationally renowned peer-review journal on physics on July 16, 2010. Cell membranes, which consist of lipid bilayers, play important roles in cells as barriers to maintain concentrations and matrices to host membrane proteins. During cellular processes such as cell fission and fusion, the cell membranes undergo various morphological changes governed by the interplay between protein and lipid membranes. There have been many theoretical and experimental approaches to understand cellular processes driven by protein-lipid membrane interactions. However, it is not fully established how the membrane elastic properties, which play an important role in membrane deformation, are affected by the protein-membrane interactions. Antimicrobial peptides are one of the most common examples of proteins that modify membrane morphology. While the pore-forming mechanisms of antimicrobial peptides in lipid bilayers have been widely investigated, there have been only a few attempts to understand the mechanisms in terms of membrane elastic properties. In particular, the effects of pore formation on the membrane fluctuation and elastic properties, which provide key information to understand the mechanism of antimicrobial peptide activity, have not been reported yet. The research team reports the thermal fluctuation and elasticity of lipid vesicles interacting with pore-forming peptides, which were measured by neutron spin-echo spectroscopy. The results of this study are expected to pay an important role in understanding the elastic behavior and morphological changes of cell membranes induced by protein-membrane interactions, and may provide new insights for developing new theoretical models for membrane fluctuations which include the membrane mediated interaction between protein patches.

The 2010 International Forum on Electric Vehicle will be held at the Korea Advanced Institute of Science and Technology (KAIST) in Daejeon, South Korea.
Universities, industries, and governments from the world gathered to make an important endeavor for the commercialization of electric vehicles that has emerged as a strong option to replace conventional cars with an internal combustion engine. With the potential benefit of electric cars, in view of environmental protection and less dependence of oil import, they still have limitations for the daily use in customers’ perspective. Electric cars are still very expensive to own with relatively short distance of driving with one charging and with the expensive and bulky nature of the batteries, in addition to the safety concerns with the Lithium batteries. The Korea Advanced Institute of Science and Technology (KAIST) will hold an international forum, at which it hopes to address a wide range of issues related to the development and commercialization of electric vehicles. The 2010 International Forum on Electric Vehicle will be held for three days at KAIST’s campus in Daejeon, South Korea, from June 17th to 19th, 2010. Internationally renowned speakers from Korea and overseas will present their views and conduct a discussion forum on the technology, market, and policy on electric vehicles. The event is open to the public. Major discussions, however, will take place on the second day, Friday, June 18, 2010, which will proceed with two sessions. In the first session, conference participants will discuss the topic of “policies and markets for electric vehicles,” and at the second session, they will take up the issue of “electric vehicle technologies.” Dr. Andrew Brown, president of SAE International and the executive director and chief technologist of Delphi, is scheduled to give a key note speech. The SAE International is a global association of more than 128,000 engineers and related technical experts in the aerospace, automotive, and commercial vehicle industries. Topics to be covered by Dr. Brown during his key note speech are, among other things, elements of market forces for hybrid electric vehicles, electric vehicles, or battery-powered vehicles; clean technologies necessary for sustainable development; pending issues facing the automotive industry to create a substantial share by electric cars and government aids to increase consumers’ buying power for expensive electric cars; technology innovation required for the improvement of batteries and power electronics; development of smart grids; and other key issues that would mature an ever-growing market for electric vehicles. President Nam Pyo Suh of KAIST will also deliver a key note remark on the overall accomplishments of online electric vehicle (OLEV) developed by KAIST. While stressing the OLEV’s technological breakthrough to succeed in the wireless in-motion power transfer through electromagnetic induction, President Suh will review the necessity of developing electric cars as a corresponding measure against climate changes and address the issues of battery weight and lifespan, charging time, and the limited amount of reserved Lithium. Dr. Steven Shladover from the California Partners for Advanced Transit and Highways (California PATH), established in 1986 in collaboration with the University of California in Berkeley and the California Transit, will attend the conference. California PATH is a multi-disciplinary program with universities statewide and cooperative projects with private industry, state and local agencies, and non-profit institutions to find solutions to the problems of California’s surface transportation systems through cutting edge research. California PATH once implemented a bold, innovative research project in the early 1990s in order to overcome the most difficult technical hurdle to reduce the heavy dependence of batteries for electric cars by adopting a non-contact transfer of electric power during vehicles’ movement. Despite the research declared as “unsuccessful” by California PATH, the implications of their innovative approach to solve an important issue inspired many researches subsequently followed—one of them is KAIST’s OLEV project. In addition, the Infineon Technologies AG, a leading semiconductor and system manufacturer based in Germany, which offers solutions for automotive, industrial and multimarket sectors for applications in communication and memory products, will come to the forum and present a paper on its expertise to develop the necessary components for electric vehicles. On the last day of the forum, all participants will have a chance to ride the Online Electric Vehicle (OLEV) at KAIST’s campus. For details of the event, please visit the website of “www.olev.co.kr/en/ifev or refer to the invitation attached herewith. About KAIST’s Online Electric Vehicle: The Online Electric Vehicle (OLEV) developed by KAIST is a dynamic plug-in electric car that receives electricity while running or stopping and thus acquired a complete mobility unlike other type of electric cars, whether hybrid or not. The OLEV reduces the size of a battery to one-fifth of the current battery installed in an electric car. Pure electric cars depend on a large bulky battery that has been a major obstacle to make the cars commercially accessible to the mass market. The OLEV gets charged wirelessly, a distinct difference to other dynamic plug-in electric cars including a tram or trolley, which directly picks up electricity from the road. To explain it further, the OLEV is electrified through power lines buried underground; when flowing low frequency of currents, an electric magnetic field is created around the underground power lines, and the pick-up gadget installed underbody of an electric vehicle converts the field into electricity; and the vehicle then uses electricity either for operation or stores it at a battery to be used for running the road that is not equipped with the power lines. The electric power generated from the underground travels to the surface of the road above 20cm-25cm. KAIST has succeeded to develop a commercial model of OLEV with a safe Electromagnetic Field (EMF), well below the international safeguard of 65mG. The actual model has been up and running at an amusement park in Seoul for the transportation of passengers. The non-contact charging method applied to the OLEV will accelerate the commercialization of electric cars by making a battery affordable and safer for a consumer.

President of Israel visited KAIST on June 9, 2010.
President of Israel, Shimon Peres, visited KAIST today on June 9, 2010 to witness the development of science and technology in Korea and explore ways of establishing collaboration and cooperation with industries and universities between Korea and Israel. President Peres led a delegation consisted of the Israeli Mister of Industry, Trade, and Labor, the Minister of Communication, and 60 business leaders from the top companies in the security, infrastructure, communication, high-tech, and water industries. Upon their arrival to the campus, the Israeli delegation was greeted by KAIST’s humanoid robot, “HUBO,” and then moved to its branch campus, IT Convergence Campus, for a ride of Online Electric Vehicle (OLEV) that has been developed by KAIST. The OLEV receives the necessary power through the cable lines buried underground, so it can be provided with a constant and continuous supply of electricity while running or stopping. Between roads and OLEVs is nothing but space. There is no electrical wires intricately crossed underbody of the electric car or above the road. The pick-up equipment installed beneath the body of the electric car collects magnetic fields created around the underground cables, which then converts the filed into electricity. The OLEV’s wireless, non-contact charging system made it possible for a battery currently used for hybrid or pure electric cars on the market to be smaller and cheaper. President Peres expressed a great interest in the technology applied to the OLVE, quoting, “the OLEV system is indeed very impressive.” He talked about efforts being made in Israel with respect to the development of electric cars. The country plans to replace the conventional transportation system with electric cars by constructing a network of battery exchange stations and roadside charge points which allow the cars to be charged whenever they are parked. “Despite the different approach taken by the two nations for the development of electric cars, I believe that transforming the automobile industry from combustion engine to electric system is the right direction we should all follow. Without addressing the current transportation system that heavily dependent on natural resources, we will not be able to promote “green growth on a global scale,” added President Peres. In addition to electric cars, President Peres took up a considerable portion of his time to exchange ideas on how to expand cooperative relations between universities in Korea and Israel, specifically in the area of space, biotechnology, nanotechnology, high-tech, renewable and alternative energy, and the EEWS initiatives that have been implemented by KAIST to find answers to global issues such as climate change and depletion of natural resources. The EEWS stands for energy, environment, water, and sustainability. In response, the president of KAIST pledged to set up a stronger and greater tie with research universities in Israel, particularly called for more collaboration between KAIST and Technion-Israel Institute of Technology. Also, the Israeli delegation had a tour for several Korean research and development centers in Daedeok Innopolis, located in the City of Daejeon, which is the 2nd largest science and research complex in Korea. Shimon Peres, the 9th president of Israel, held many of important government positions in Israel, among other things, Prime Minster and Minister of Defense. He won Nobel Peace Prize in 1994, together with Yitzhak Rabin and Yasser Arafat for the conclusion of a peace agreement, Oslo Accords, between Israel and Palestine Liberation Organization.
