Life for the modern convenience
Japan's future green energy-saving and environmentally-friendly buses
Automobile, life for the modern convenience of many, but at the same time, today's automotive society is faced with many difficult issues, such as laptop battery, vehicle congestion, traffic accidents, air pollution, and so on. In particular, the steadily climbing oil prices, has made people feel great pressure. In Japan, a number of new transport system to practical use in the form presented in front of people.
Ultra-quiet bus
No wheels LINIMO, by the strength of electromagnetic stone floating in orbit of only 6 mm above the road, according to train operators --- Aichi Rapid Transit Co., Ltd., the "sitting in the car, just like in the ice field has been people the feeling of pulling away hp battery. "In addition, train traffic noise is very small, only the power of a slight change occurred in the sound device. This car is the world's constant conductivity-type ultra-high-speed maglev train in the first case of practical use. Although LINIMO high cost of their vehicles, but because it is unmanned automatic operation, but also due to vehicle and track non-contact, so almost no maintenance and so on, from these in terms of running costs can be controlled in a low level. LINIMO has the potential to become the future to replace the railroad train long-distance transport of the most powerful candidate.
Smart Bus
Vehicles similar to the bus 20 meters running parade in the interval between the laying of gas have induced magnetic special road markings, and these vehicles are unmanned automatic driving. When come to fork in the road, the queue at a number of vehicles in the opposite direction, and finally by the people driving on roads in general.
This display of the scene inside the car running for a top speed of 30 kilometers, but if the use of natural gas engine will be able to reach the speed of vehicles. Future economic benefit in the subway lower small cities, this car wants to be a large number of transport in the transport distance.
Hybrid bus
This hybrid bus is the fuel cell and nickel-metal hydride 417066-001 battery, hstnn-lb31 battery(secondary battery) both the mixed-energy driving force. Based on hydrogen fuel cells for fuel, so that hydrogen and oxygen in the air a chemical reaction occurs, and then made its generated electricity. Fuel cells emit only water (mostly water vapor), while the secondary battery produced only electricity as a source of energy, therefore, be regarded as such a hybrid bus is a real green (environmentally friendly) means of transport.
Developed by the Toyota Motor Corporation hybrid buses, the installation of the two output power of 90 kW fuel cell and engine braking when electricity is stored in the large-capacity rechargeable battery, such as when buses loaded with passengers in the last ramp, the vehicle will use the second battery to initiate the engine. Hybrid bus from the point of view and the general appearance of the bus is not that great distinction, however, has been approached will find that there is no emission hybrid buses from the unpleasant smell, it is a quiet running characteristics, almost no sound.
Europe will hydrogen fuel cell R & D as a long-term plan, it was reported that the European fuel cell organization is planning to hydrogen fuel cell R & D for future long-term plan.
European hydrogen technologies and fuel cell technology forum is sponsored by the European Commission, there are industry-renowned enterprises, research units, such as was established in 2002.
"Using hydrogen as fuel the prospect of very exciting, we have designed the car model by 2020 can be achieved and the large scale commercial production", the organization that Janez Potocnik.
"By combining hydrogen fuel cell technology and a collection of technologies, as well as the support of the European Commission, hydrogen technology and fuel cell technology platform to ensure full use of these research data to meet the needs of the future development of the industry."
Use of hydrogen as a fuel, HFP that can reduce carbon dioxide, methane and other greenhouse gases, improve local air quality, the driving force to provide security. In addition, the organization has identified hydrogen fuel cells as the most important goal of development of applications.
HFP Department's work is divided into two, first of all strategic planning stage, to provide a 10-year research, development and implementation plan, and the other is the implementation phase, mainly the implementation of specific and important strategic steps to ensure that the objectives in 2020 to achieve.
Research objectives include reducing the cost of fuel cell system to improve fuel cell performance and durability and reduce the cost of hydrogen fuel supply.
Smallest methanol fuel cell
Japan's Toshiba Corporation to develop methanol fuel cell DC was "Guinness World Records" recognized as the smallest of similar products, the 411462-421 battery, hp pavilion dv2000 battery 56 centimeters long, 22 centimeters wide, 4.5 centimeters thick, applied to a variety of portable electronic equipment.
New highly efficient solar cell 4 times
Conversion rate is expected to develop up to 20% of the solar cell, according to Japan's "Daily News" reported that the Japan Institute of Advanced Industrial Science and Technology developed the world's highest rate of solar energy conversion of organic thin-film solar cells, the conversion rate has reached the existing organic thin-film solar 4 times the battery. The report said that the existing organic thin film solar cell is two layers of organic semiconductor thin-film bonding, the solar energy to electrical energy conversion rate is about 1%. New type of organic thin-film solar cells in the middle of the existing two-tier structure by adding a hybrid film, into a 3-layer structure, so that generated electricity increased by the contact area between elements and greatly improve the conversion rate of solar energy. Organic thin-film solar cells use light plastic materials, soft substrate, so people look forward to its high practical use. The researchers said that further study is expected to develop a conversion rate of 20%, can be actually used in the organic thin-film solar cells. Perhaps in the near future, plastic materials, solar cells will be integrated into people's daily life.
Laptop battery said researchers will be able to use for eight hours, many people have laptop computers can not do without.
Said researchers expected the near future, notebook computer batteries will be able to use for 8 hours without recharging. Industry experts said that the use of new compounds to create the battery, the battery will greatly extend the time for power supply.
But experts said that the need for comprehensive improvements in notebook computers, including the chip maker's methods and techniques to reduce display power consumption.
Since the notebook computer market, the user is too short working hours of battery has been great advice. Forrester Research research institutions have done in 2000, a survey is too short battery life of notebook computer users complained that one of the largest.
Chip giant Intel's chief mobile technology officer Treanor said that the notebook computer has just come out, people are more concerned about its performance. At that time, the majority of laptop battery up to 2.5 hours continuous use. However, he believes that the life of laptop batteries has increased a lot.
Treanor said that the industry has developed a number of technology, the hp pavilion dv6000 battery, hp pavilion dv2500 battery in the same space to store more energy, but the specific production requirements from a long way to go there.
