On the official website of Japan's Ministry of Science and Technology, it was reported that the Japanese Institute of Industrial Technology, in collaboration with ATSUMITEC—a leading auto parts manufacturer—has developed a groundbreaking technology that uses motorcycle and car exhaust gases to generate electricity. This innovative system captures unburned components from the exhaust and the residual heat, converting them into usable electrical energy through fuel cells and thermoelectric generators. The company expressed its intention to work towards widespread adoption of this technology by 2015.
The research team integrated a solid oxide fuel cell (SOFC) and a thermoelectric conversion element directly into the engine’s exhaust system. These components work together to recover energy from the exhaust gas, which typically reaches temperatures around 500°C. According to experimental results, this system can recover approximately 2.5% of the total energy from the exhaust of a 400cc engine—an amount equivalent to the output of a 400-watt power plant.
Looking ahead, the researchers plan to focus on improving the cost-effectiveness and long-term durability of the technology. Industry reports suggest that this innovation has broad potential applications beyond motorcycles and cars. It could also be used in industrial settings, such as factories, where waste heat from exhaust systems is commonly released. By making better use of this otherwise wasted energy, the technology holds great promise for improving energy efficiency and reducing environmental impact.
The headlamp is a kind of lighting tool worn on the head, mainly used to free the hands of lighting. The design of the headlights allows users to carry out various activities, such as night walking, camping, exploring, etc., without the need for hand-held lighting, thereby freeing up both hands for other operations. Headlamp is usually composed of headlamp body, charger, rechargeable battery, power socket and cable, etc., to provide stable lighting effect. The use of headlights is widely used, not only for outdoor activities, but also for some indoor activities, such as night reading, repair and so on.
When choosing a headlamp, there are several key factors to consider: brightness, irradiation distance, battery life, waterproof and dustproof ability. The ideal headlamp should have enough brightness to cope with different lighting needs, good irradiation distance to ensure safety, long battery life to meet the needs of long-term use, and a certain waterproof and dustproof ability to adapt to various environments. In addition, the type of headlamp battery is also an important consideration, you can choose a rechargeable or replaceable battery headlamp, according to the use of habits and needs to choose.
The brightness of the headlamp is usually measured in lumen, and the higher the lumen value, the higher the brightness of the lamp. Waterproof and dustproof rating is also an important indicator of headlamp performance, in general, IPX6 or above waterproof rating can meet the needs of most outdoor activities. When choosing a headlamp, you should also consider its light source type, such as LED, halogen or xenon, etc. Each light source type has its own unique advantages and disadvantages, and is suitable for different scenes and needs.
