In 3, Chicago held the first World's Fair. The organizers decided to use the latest technological achievements of electric lighting, Tesla's Westinghouse company bid successfully. As a result, Edison cursed on the spot: "I don't sell you electric lights, see what lighting!" But Tesla will not give in, he called on all employees to work overtime to rush the light bulb, and finally completed at the last minute. On May 1, 1893, 100,000 spectators filled the hall.
4He even killed an elephant with alternating current in public to discredit the status of alternating current in people's minds. In 1893, at the Chicago World's Fair, this "current war" was finally played out. At that time, Edison's newly formed General Electric Company and Westinghouse Company for the Expo lighting rights contract in a fierce competition. 5. And at the opening of a World's Fair in Chicago in January 1893, Tesla stunned the crowd by showing how "alternating current" lit 90,000 light bulbs simultaneously. Because this is "direct current" fundamentalTechnology Expo wireless charging , here are just a few. Build energy saving, new energy vehicles, 4G mobile communications, electronic tags... These advanced scientific and technological means will be fully applied to the upcoming Shanghai World Expo. At the scene of the National Two Sessions, relevant representatives and members carefully took stock of "Expo science and technology" to reporters.
2, Energy conservation and environmental protection Japan Pavilion in the design of the use of environmental control technology, so that light, water, air and other natural resources are maximized. The double-layer outer film with high light transmittance and the solar cell inside the pavilion can make full use of solar energy resources.To achieve efficient light conduction and power generation; The exhibition hall will use the latest technology such as circular breathing holes. 3. Artificial intelligence research has always been one of the hotspots of scientific research in various countries, and artificial intelligence technology represented by robots will become a major attraction of the Shanghai World Expo. Unlike in the past, robot technology is mostly used for display, at this World Expo, more countries will use robots to welcome guests or show guidance, and using robots to "support the front" has become a trend.
The overall goal of the project is to establish a set of advanced and perfect building wiring system to provide access and wiring for various applications, including voice, data, multimedia, etc., to achieve flexible system configurationEasy to manage, easy to maintain, easy to expand the purpose. This project is a landmark building of Shanghai World Expo. The design scheme and products of this project are introduced below.
