“Benjamin Franklin Drawing Electricity from the Sky” 1816 Benjamin West
Benjamin Franklin conducted his famous experiment with lightning on June 10, 1752.
He used a kite and a key to demonstrate that lightning was a form of electricity.
This experiment marked an important milestone in understanding the nature of electricity
and laid the foundation for the development of lightning rods and other lightning protection systems.
Seasonal extreme weather patterns in the United States, resulting in damages to education facilities and delays in outdoor athletic events — track meets; lacrosse games, swimming pool closures and the like — inspire a revisit of the relevant standards for the systems that contribute to safety from injury and physical damage to buildings: NFPA 780 Standard for the Installation of Lightning Protection Systems
This document shall cover traditional lightning protection system installation requirements for the following: (1) Ordinary structures (2) Miscellaneous structures and special occupancies (3) Heavy-duty stacks (4) Structures containing flammable vapors, flammable gases, or liquids with flammable vapors (5) Structures housing explosive materials (6) Wind turbines (7) Watercraft (8) Airfield lighting circuits (9) Solar arrays
This document shall address lightning protection of the structure but not the equipment or installation requirements for electric generating, transmission, and distribution systems except as given in Chapter 9 and Chapter 12.
(Electric generating facilities whose primary purpose is to generate electric power are excluded from this standard with regard to generation, transmission, and distribution of power. Most electrical utilities have standards covering the protection of their facilities and equipment. Installations not directly related to those areas and structures housing such installations can be protected against lightning by the provisions of this standard.)
This document shall not cover lightning protection system installation requirements for early streamer emission systems or charge dissipation systems.
“Down conductors” must be at least #2 AWG copper (0 AWG aluminum) for Class I materials in structures less than 75-ft in height
“Down conductors: must be at least 00 AWG copper (0000 AWG aluminum) for Class II Materials in structures greater than 75-ft in height.
Related grounding and bonding requirements appears in Chapters 2 and Chapter 3 of NFPA 70 National Electrical Code. This standard does not establish evacuation criteria.

Didn't really plan for all possibilities, did they. 🤓
Churches and chapels are more susceptible to lightning damage due to their height and design. Consider:
Height: Taller structures are more likely to be struck by lightning because they are closer to the cloud base where lightning originates.
Location: If a church or chapel is situated in an area with frequent thunderstorms, it will have a higher likelihood of being struck by lightning.
Construction Materials: The materials used in the construction of the building can affect its vulnerability. Metal structures, for instance, can conduct lightning strikes more readily than non-metallic materials.
Proximity to Other Structures: If the church or chapel is located near other taller structures like trees, utility poles, or buildings, it could increase the chances of lightning seeking a path through these objects before reaching the building.
Lightning Protection Systems: Installing lightning rods and other lightning protection systems can help to divert lightning strikes away from the structure, reducing the risk of damage.
Maintenance: Regular maintenance of lightning protection systems is essential to ensure their effectiveness. Neglecting maintenance could result in increased susceptibility to lightning damage.
Historical Significance: Older buildings might lack modern lightning protection systems, making them more vulnerable to lightning strikes.
The risk can be mitigated by proper design, installation of lightning protection systems, and regular maintenance.
When is it ever NOT storm season somewhere in the United States; with several hundred schools, colleges and universities in the path of them? Hurricanes also spawn tornadoes. This title sets the standard of care for safety, resilience and recovery when education community structures are used for shelter and recovery. The most recently published edition of the joint work results of the International Code Council and the ASCE Structural Engineering Institute SEI-7 is linked below:
Given the historic tornados in the American Midwest this weekend, its relevance is plain. From the project prospectus:
The objective of this Standard is to provide technical design and performance criteria that will facilitate and promote the design, construction, and installation of safe, reliable, and economical storm shelters to protect the public. It is intended that this Standard be used by design professionals; storm shelter designers, manufacturers, and constructors; building officials; and emergency management personnel and government officials to ensure that storm shelters provide a consistently high level of protection to the sheltered public.

United States national electrical trade standards prioritize safety, reliability, and economic efficiency in electrical systems. Governed primarily by the National Electrical Code upon which the University of Michigan has had a vote since 1996.
The NEC outlines requirements for wiring, equipment installation, grounding, and overcurrent protection to prevent hazards like electrical shocks, fires, and equipment failures. Compliance ensures safe operation in residential, commercial, and industrial settings. Standards also promote energy efficiency, encouraging practices like proper insulation, energy-efficient lighting, and renewable energy integration to reduce costs and environmental impact.
Organizations like the Occupational Safety and Health Administration (OSHA) and Underwriters Laboratories (UL) further enforce safety through regulations and product certifications. Adherence to these standards minimizes risks, ensures system longevity, and supports economic benefits through reduced energy waste and maintenance costs, fostering a safe and sustainable electrical infrastructure.
European Union electrical trade standards prioritize safety, interoperability, and economic efficiency across member states. Governed by the Low Voltage Directive (LVD) 2014/35/EU and harmonized standards from the European Committee for Electrotechnical Standardization (CENELEC), these regulations ensure electrical equipment operates safely between 50-1000V AC or 75-1500V DC. Standards like EN 60335 address appliance safety, while EN 50110 outlines safe maintenance and operation practices. Compliance with CE marking requirements certifies adherence to safety, health, and environmental standards, facilitating market access.
For economy, the EU promotes energy efficiency through directives like the Ecodesign Directive 2009/125/EC, mandating efficient lighting, motors, and renewable energy integration to reduce consumption and costs. National regulations align with EU standards, ensuring consistency. These measures minimize electrical hazards, enhance system reliability, and support sustainability by reducing energy waste, fostering cost-effective, safe electrical infrastructure across the EU’s diverse markets.
Non-profit organizations and unions play a critical role in training electricians, ensuring skilled, safe, and competent professionals. Organizations like the National Electrical Contractors Association And unions such as the International Brotherhood of Electrical Workers Offer structured apprenticeship programs combining classroom instruction with hands-on training.
These programs cover electrical theory, National Electrical Code compliance, safety practices, and emerging technologies like renewable energy systems. Non-profits often provide certifications, scholarships, and continuing education to promote workforce development. Unions advocate for fair wages and safe working conditions, while their training centers emphasize practical skills, ensuring electricians meet industry standards and contribute to reliable, efficient electrical systems.

The crossover was inevitable — wine inspired coffee. Respecting today’s release of Beaujolais Nouveau in the Vallée de la Saône we reflect upon “enlightened” coffee varieties and preparations that classically “pair” with wine — either as contrast or complement. Anaerobic or carbonic-maceration coffees (very “winey” ferments). Many modern specialty lots taste like red fruit jam, Concord grape, or even Lambrusco. As with the wine itself: not for coffee snobs.
Beaujolais Nouveau is a young, light, fruity red wine made from Gamay grapes in the Beaujolais region of France (just south of Burgundy). Unlike most red wines that are aged for months or years, Beaujolais Nouveau is rushed from the vineyard to the bottle in just 6–8 weeks using a special fermentation technique called carbonic maceration (which gives it its signature banana/strawberry/candy-like flavors).
By French law, it cannot be released before one minute past midnight on the third Thursday of November. This has turned the release into a global marketing event that started in the 1970s–80s:
At midnight, the phrase “Le Beaujolais Nouveau est arrivé !” (“The Beaujolais Nouveau has arrived!”) is shouted in bars, restaurants, and wine shops.
There used to be literal races (by car, helicopter, hot-air balloon, etc.) to get the first bottles to Paris and later to cities around the world (Tokyo, New York, London…).
It’s marketed as a fun, unpretentious “party wine” meant to be drunk young and slightly chilled.
Reputation today
Serious wine lovers often look down on it (it’s simple and can taste artificial to some).
But millions of people still love it as the unofficial kickoff to the holiday/winter drinking season — a light, festive, easy-drinking red that says “the new vintage is here!”
Beaujolais Nouveau Day celebrates the year’s freshest, fruitiest red wine released with maximum fanfare and zero pretension.
“Wildwood Flower”is a beloved American folk song, best known as a standards of early country music through the recordings of the Carter Family. However, its roots trace back much further to the mid-19th century as a parlor song—a popular genre of sentimental, sheet-music tunes performed in middle-class homes on piano or guitar.
The song’s theme is a classic tale of unrequited love: a young woman, adorned with flowers in her raven-black hair, reflects on being abandoned by her lover. She compares herself to a “frail wildwood flower” that’s been neglected, vowing to move on despite her heartbreak. This Victorian-era sentimentality made it a hit in sheet music sales, but it quickly entered oral tradition, evolving through folk processes as it spread across the American South.
By the late 19th and early 20th centuries, the song had variants circulating in Appalachia and beyond, including titles like “The Pale Amaranthus” (collected in Kentucky and North Carolina around 1911), “Raven Black Hair,” “The Pale Wildwood Flower,” and “The Frail Wildwood Flower.” These changes often shifted lyrics slightly—such as moving verses around or altering metaphors—to fit local storytelling styles, preserving its melancholic core while adapting to rural singers.
