Humans are quite rightly fascinated by black holes, but could we ever harness them as an energy source? New research poses this question in order to explore some of the most wonderous
More mysterious are the giant black holes found at the centers of galaxies — the "supermassive" black holes, which can weigh millions or billions of times the mass of the Sun.
Theoretically, a black hole could act as a power source, but it would not be nearly strong or reliable enough. A black hole with the mass of our sun would take half a trillion times the age of
A black hole with the mass of our sun emits less power than a household lightbulb and takes 10^67 years to evaporate. Only primordial black holes, tiny relics from the Big Bang with masses around
Problem 2 - How much mass would have to be accreted in order for the supermassive black hole to have the same power as an average quasar with a luminosity of about 2 trillion times the luminosity
Accretion around a black hole can release up to 40% of the infalling mass as energy, depending on the spin of the black hole. That is nearly sixty times more efficient than the Sun''s
Black holes spin and extract energy through powerful magnetic fields, fueling the formation of energetic jets. Advanced simulations show that up to 70% of this energy can be
Since spacetime in the ergosphere rotates along with the horizon, and 0-30% of the hole''s total energy is there, one can (in principle) anchor a “crank handle” there and have the black hole turn a distant motor.
The enormity of a black hole could theoretically hold trillions of solar cells without reaching full capacity, yet this comparison brings attention to the disparity in physicality and function.
Thus a star as massive as the Sun can be prevented from becoming a black hole when it collapses to the size of the Earth, and the internal "electron avoidance" pressure (called the "degenerate electron
Empa Solar Energy Europe is a leading energy storage equipment manufacturer and integrator based in Poland, serving the European market. We specialize in C&I energy storage systems for factories and warehouses, industrial battery storage systems for heavy-duty applications, factory energy storage systems (ESS) to optimize production, commercial battery energy storage systems (BESS) for retail and offices, enterprise storage solutions for corporate campuses, industrial park energy storage for multi-tenant sites, commercial battery storage for peak shaving, industrial battery storage systems for backup power, and remote base station power solutions for telecom towers. Our portfolio also includes lithium-ion batteries, system-level battery management systems (BMS), energy conversion systems (PCS), energy storage battery system cabinets, communication cabinets for telecom and data centres, integrated PV-storage systems, distributed energy resources, deep discharge battery technology, and containerised BESS. As a full-service provider, we also offer modular battery racks, backup emergency power, and zero‑carbon microgrids. Our advanced lithium‑ion and sodium‑ion solutions ensure safety, scalability, and high performance for commercial, industrial, and utility projects across Europe.
Our modular energy storage portfolio ranges from compact lithium-ion batteries to 20ft/40ft mobile containers and outdoor all-in-one storage cabinets with IP54 protection. We are a leading energy storage equipment manufacturer, offering communication cabinets for 5G/telecom, server racks for data centers, and IP54 rated enclosures for harsh environments. Our stackable design allows flexible capacity expansion, while our grid-forming technology ensures stable off‑grid operation. Whether for remote base stations, off‑grid power systems, backup emergency power, integrated PV-storage or large zero‑carbon parks, our products feature advanced thermal management, deep discharge cycling, and compliance with European and international standards. We also provide professional energy storage system installation and after‑sales support across Europe.
