Power Efficiency Theory (PET) argues that the value of a physical or computational system should be influenced by two things improving at the same time: its performance increases and its energy cost per unit of output declines. In proof-of-work networks, this can be measured through factors such as network hashrate, mining-machine output, and ASIC efficiency.…

Monero’s Power Efficiency Index (PEI) paints a much tighter valuation picture than Zcash. From a 2022 baseline of $96.50, Monero’s PEI climbed to $141.40 in 2023, $207.19 in 2024, $303.60 in 2025, and $444.87 in 2026. That represents a 4.61× compounded power-efficiency progression, or roughly +361%, as Monero’s network performance and energy efficiency improved over…

Litecoin’s recent mining expansion becomes more significant when placed beside Bitcoin and Zcash under the same Power Efficiency Theory framework. Rather than comparing the raw hashrates of three fundamentally different proof-of-work algorithms, the model normalizes each network to its own approximate 2022 baseline and measures two forms of physical improvement: growth in network computational output…

Zcash’s resurgence is interesting because it gives us a useful Proof-of-Work comparison outside of Bitcoin. Over roughly the past four years, the Zcash network increased from about 8.2 GSol/s to 25.4 GSol/s, while leading Bitmain Equihash hardware improved from roughly 3.60 J/KSol to 3.15 J/KSol. Under the Power Efficiency Theory framework, that produces an estimated…

Imagine looking through an ordinary window that is quietly producing electricity throughout the day. That vision is moving closer to reality as researchers in South Korea continue developing transparent solar cell technology capable of generating power while remaining clear enough for everyday use. Instead of absorbing visible light like traditional solar panels, these advanced photovoltaic…

SoftBank Group, in a massive public-private partnership with the U.S. Department of Energy, has officially broken ground on the “Stargate” AI power and data campus in Piketon, Ohio. Located at a decommissioned uranium enrichment site, the project is staggering in scale: it aims for 10 gigawatts of computing capacity supported by a dedicated $33 billion…

BitCluster, a Russian Bitcoin mining solutions provider, is set to launch a significant project in Ethiopia, which will revolutionize the cryptocurrency mining landscape. Scheduled to commence operations in January 2024, this venture involves the construction of a 120-megawatt (MW) data center in Addis Ababa, Ethiopia’s capital. The facility, spanning an impressive 30,000 square meters and…

We know that Force is equal to mass times acceleration. A home has physical mass, structural strength, and load-bearing capacity. These properties give it force capacity in the physical sense. However, a home does not move and does not perform continuous work, so its velocity is effectively zero. As a result, its power output, in…

A string inverter is a centralized power conversion device used in solar energy systems to transform direct current (DC) electricity generated by multiple photovoltaic (PV) panels into alternating current (AC) electricity suitable for use in homes, businesses, or the electrical grid. In this configuration, solar panels are electrically connected in series to form a “string,”…

Solar inverters are essential devices in photovoltaic (PV) systems that convert the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity, which is compatible with household appliances and the utility grid. They serve as the “brain” of a solar energy system, not only enabling energy conversion but also managing system performance,…

PV modules, commonly known as solar panels, are the foundational units of solar energy systems. Each module contains numerous photovoltaic cells—usually made from monocrystalline or polycrystalline silicon—that work together to generate electricity through the photovoltaic effect. These cells are embedded between layers of protective materials: a front layer of tempered glass for durability and light…

This DIY electronic solar tracker is a clever and simple project that helps a small solar panel automatically follow the sun to capture the maximum amount of sunlight throughout the day. The schematic illustrates a simple automatic solar tracker that uses two light-dependent resistors (LDRs) to sense the direction of the brightest sunlight and drive…
