Korean public transport will enable wireless power supply system

In today's world, where electricity powers most public transportation systems, the slow progress in the energy sector has become a pressing issue that needs urgent attention. Recently, South Korea announced its plan to implement wireless power supply systems in public transport, aiming to replace traditional wired infrastructure. This move marks a significant step forward in modernizing urban mobility. Researchers from the Korea Advanced Institute of Science and Technology (KAIST) have made groundbreaking advancements in wireless charging technology. They've developed a system called On-Line Electric Vehicles (OLEV), which is currently undergoing field tests. The OLEV system uses inductive charging, allowing electric vehicles to draw power from the road surface through embedded coils beneath the pavement. The technology enables vehicles to charge while in motion, eliminating the need for frequent stops at charging stations. According to the research team, the current efficiency of the system reaches up to 85%, which is a remarkable achievement in wireless power transfer. If the test results continue to be positive, South Korea plans to roll out this innovative system on a larger scale, potentially transforming how cities manage public transport. This development could not only improve the efficiency of electric vehicles but also reduce dependency on bulky batteries and charging infrastructure. It represents a promising future where clean, efficient, and continuous power delivery becomes the norm in urban transit systems. With further refinement and expansion, wireless charging could soon become a standard feature in smart cities around the globe.

Microcentrifuge Tube

High-performance microcentrifuge tubes, optimized design, and high-performance quality help protect your samples. Microcentrifuge tubes are made of polypropylene (PP) and are highly mechanically stable, ensuring your samples are stored, run and centrifuged worry-free.

Microcentrifuge tubes have a maximum centrifugation tolerance of 25,000 x g and are autoclavable (20 minutes, 121°C). The centrifuge tube adopts a snap-on tube cover design, which can be operated with one hand and has good sealing performance, which can effectively prevent liquid leakage; the tube wall is smooth, and the tube body is designed with a frosted area for convenient marking.
