2019年6月10日 · Lightning is a huge electrical discharge that results from the rising and sinking air motions that occur in thunderstorms. Lightning can travel from cloud to cloud, within the same cloud, or between the cloud and ground. The lightning in the accompanying photograph …

2025年2月1日 · Circular lighting is more than just a lighting upgrade, it is a change in how we look at lighting systems and the management of resources. The environmental benefits are clear to see, and as more businesses look to improve their eco-responsibility, circular lights will become the go-to solution for positive environmental change.

Apparent Circular Lightning May 1, 1997, near Patterson, New Jer sey. Between 3 and 4 PM, D. Quinlan was driving along Route 80. A dark line squall was approaching from the west. Quinlan observed many horizontal strokes of lightning passing from cloud to cloud.

2023年7月1日 · Height structures such as wind turbines (WTs) are exposed to lightning due to the installation location on heights, plains, or coastal zones. The grounding system of WTs plays an important role in repelling the energy of lightning waves and reducing the resulting over-voltages.

2014年1月30日 · The tests showed significant damage caused by lightning impact due to thermal degradation caused by Joule heating. Damage under Level 1 strike was significantly greater than under Level 2 due to the lower integral action of the latter.

2016年9月12日 · The immediate business case for fast-tracking the move to a circular economy and closing the materials loop became vitally clear after Philips and the Ellen MacArthur Foundation shared their common vision for a resource-eficient and, ultimately, regenerative circular economy.

2024年8月15日 · In this paper, the mechanical impact loads (MILs) of lightning are decomposed into acoustic shock waves from arc channel expansion (AESW), electromagnetic force (EMF), and shockwave overpressure from surface explosion (SESW).
