The power grid is a vast and intricate system composed of generation units (like hydroelectric, thermal, and renewable energy plants), transmission lines, substations, transformers, and distribution networks that deliver electricity to homes and businesses. Orchestrating a black start across this interconnected web is a highly complex task—each component must be reactivated in a precise sequence to avoid overloads, instability, or cascading failures. Communication between grid operators, synchronization of frequency and voltage levels, and the gradual reintroduction of demand are all crucial elements. It’s a delicate dance that requires meticulous planning, real-time coordination, and robust contingency protocols. ...

The oldest human-made structures we know — the pyramids — have endured for a few thousand years. Now, Sweden is constructing something meant to endure for a staggering 100,000 years. Their nuclear waste storage facility is designed to surpass the lifespan of every bridge or building ever created by humanity—by a factor of 100. This facility will store approximately 12,000 tonnes of nuclear waste at a depth of 500 meters in rock that is 1.9 billion years old. The spent fuel will be sealed in corrosion-resistant copper canisters, each five meters long, and surrounded by clay before being buried. ...
