The annual scientific symposium “Energy of thought” has opened the “Global Energy” laureate’s week
Today, on June 16th, the scientific symposium “Energy of thought” has opened the “Global Energy” laureate’s week. It took place at the Saint Petersburg Electrotechnical University LETI.
As a recall the “Energy of thought” is a unique symposium of “Global Energy”, Non-profit partnership. It builds the dialog between the representatives of different scientific genders. This time it has united the 2015 Global Energy Prize laureates Jayant Baliga and Shuji Nakamura with the winners of “Energy of Youth” -2013.
The GEP laureates’ presentations were devoted to their research and have clarified their achievements. Thus professor Baliga – the author of Insulated Gate Bipolar Transistor – has told about the role of his technology in the field of energy control and distribution. “-IGBT is an embedded technology hidden from the eyes of society but it is widespread globally. It is used in different sectors of economy: consumer, industrial production, transportation, medicine and even for the wind and solar energy generation” – declared Mr. Baliga. Its socio-economic impact is tremendous. For the first time the scientist has announced absolutely new statistics. In the last 25 years, IGBTs saved over 73,000 TW·h of energy, over 1,48 trillion gas gallons, and decreased CO2 emissions by 109 trillion lbs. The customer's savings exceeded $23,7 trillion! Thus IGBT not only improves the quality of life for billions of people around the world but also mitigates our impact on the environment.
Professor Nakamura has also shared his innovation with the participants of “Energy of Thought” symposium. He has created a blue-light emitting diode and commercialized it. It brought white energy-efficient lightning to the world and resulted in revolution in the world of gadgets and technologies. To the surprise of attendees Shuji Nakamura has announced that he invented blue LED by chance. He created experiments while working on raw materials. He used GaN which was abandoned by the majority of scientists. “– It was the most difficult challenge but the most interesting as well! Other scientists used zinc due to its crystals being more effective and expectations that their performance characteristics in the production of efficient source of energy will be amazing. Those expectations failed. And I came to the invention by using crystals with gallium!” - mr. Nakamura recalls. As for now, his inventions are used by all companies involved with manufacture of semiconductors, mobile phones, digital camera recorders, TV and DVD appliances, airplane and car systems, street lighting systems and much more. According to experts, efficiency of a white LED is 20 times the one of a traditional incandescent bulb. As DOE reports, transition to LED-based lighting will allow 300 TWh savings and reduce annual CO2 emissions by 210 million metric tons only in the USA.
Young scientists, the winners of All-Russian "Energy of Youth" contest, have received grants for the continuation of their research and have delivered their results at the symposium. They have astonished the attendees with their projects. For example, Pavel Strizhak has told about the development of main elements for the theory of energy-efficient and safe fine particles coal fuels ignition in power plants. Vyacheslav Kulagin shared his work on energy trends forecasting and Vasily Pavlichenko has announced a waste-free way of biofuel production through creation of genetically-modified types of woody plants in the Far East and Siberia. All projects have huge practical application and open new possibilities in the energy field.
