I want to do something specific in this article. I want to take one entry from my 2017 book and walk it forward, year by year, all the way to a product that is live on cri-one.com today. The entry I have chosen is short. It is one hundred and twenty characters long. It reads in its entirety:

using lasers to generate high potential energy in combination with solar receiving cells

That is entry #284 of Invent Depositions. It was written in 2017 and published in November of that year. The reason I am picking this entry is that it sits at the bottom of an architecture that, nine years later, has grown into the Artificial Laser Solar Recycle Building product on cri-one.com, listed at a $500 million acquisition target with a thirty-one-page documentation package, an engineering blueprint, a power-IC cell specification, a built-and-tested optical-chain analysis, and a formal industrial safety bulletin. The journey from those 120 characters to that 553-line safety bulletin is the case study for everything I want to say in this series about how depositions become products.

The 2017 sentence

Read the sentence again and ask what it claims. Using lasers to generate high potential energy in combination with solar receiving cells. That is a remarkably general claim. It does not specify what kind of lasers. It does not specify the wavelength. It does not specify the architecture of the solar receiving cells. It does not specify the geometry of how the lasers and the cells are combined. It says only that, taken together, the combination generates high potential energy.

This generality is intentional. The patent law principle behind generality at the disclosure stage is that priority attaches to the concept, not the embodiment. By stating the concept broadly, I preserved the right to elaborate it into any number of more specific embodiments later, with priority dating back to the disclosure of the broad concept. If I had specified, in 2017, that the lasers were 940-nanometer infrared LEDs and the cells were multi-junction InGaP/GaAs/Ge stacks, then I would have priority on that one specific embodiment but no priority on any other.

The other thing to notice about the 2017 sentence is what it implicitly commits to. It commits to the proposition that combining lasers with solar cells produces, somehow, high potential energy. It does not say more than the lasers put in — that would be a thermodynamic violation. It says high. The careful reader of the entry, looking back from 2026, will see that the language was chosen to be defensible: the system can generate high power because the lasers are pumping an optical resonant cavity that is ALSO fed by ambient solar energy. The lasers are the switch. The ambient solar is the fuel. The combination is what produces the high output. The 2017 sentence carries all of that in its 120 characters, if you know to look for it.

What surrounded the entry in the book

Entry #284 did not stand alone. It sat in a constellation of related entries — entries #188, #190, #191 on laser theory and energy expansion, entries #335 through #337 on the building-scale realization, entries #950 through #960 on the LED variant of the architecture with synthetic photosynthesis cells, entries #979 and #980 on the amplified reflective tunnel, entries #1655 through #1658 on the solar recycle naming, and the 2019 follow-on entries #1609 through #1616 on the chip-scale equivalent of the same architecture. Read together, the cluster is a complete engineering specification for what I now call the Private Energy Building. Read one at a time, each entry sounds modest. The strategy was to disclose the whole architecture as a constellation of small entries, each of which carries priority on a small piece, so that the combination is documented even if no individual entry would be patentable on its own.

The keystone of the constellation is entry #190 and its continuation in #191. These are the entries that establish the mathematical claim of the architecture. They use language that is, I admit, more poetic than precise: “laser theory – energy – expansion of a sum = accelerated motion, amplified by mass squared.” Read literally, those words do not parse as a mathematical equation. Read as an indicator of the mathematical structure I had in mind, they unambiguously describe an amplification topology in which the output energy is the sum of a direct term and a squared term, with the squared term arising from the round-trip coupling of a resonant optical cavity.

In modern engineering notation, the claim has become:

a + m² = E

Amplitude plus mass squared equals energy. The input amplitude a is the LED priming signal plus the ambient solar collection. The coupling coefficient m is the round-trip cavity coupling, bounded between zero and one. The squared term m² is the closed-loop contribution from photons that make at least one round trip inside the cavity before being absorbed by the cell. The total output E is the sum of the direct-through term and the closed-loop term, and it is bounded by the total energy supplied (the LED plus the ambient), satisfying the first law of thermodynamics.

The equation is real engineering. The equation is also a 2017 disclosure with priority back to the publication of the book. That priority is the foundation of every claim in the Private Energy Building product.

The 2018-2019 elaborations

Two years after the book shipped, in 2019, I added a second tranche of entries that filled out the architecture at chip scale. Entries #1609 through #1616 describe what I called the pico-nano voxel chip-processing-printing architecture, which is the same four-ingredient stack (conductive material, non-conductive material, empty-space looped vectors, and a software placement layer) realized at chip scale instead of building scale. The 2019 entries make it explicit that the building and the chip are the same architecture at different scales. This was important. It meant that the entire cri-one.com product line that grew out of the building-scale invention — Projects 18, 26, 30, 31, 39, 40, and 44, all of which are AutoPhi voxel-processor variants — share a common ancestor with the Project 48 Private Energy Building. They are scale variations of the same intellectual property, all anchored to the 2017 priority date.

In the same period, I also wrote a sequence of entries that I called the LED variant of the building — entries #950 through #960. These nine entries describe the same architecture but with LED light sources rather than lasers, with green solar crystal receivers performing what I called synthetic electra-photosynthesis. The LED variant is the lower-cost realization of the architecture. It is what makes a handheld version possible (more on that later) and it is what makes the building affordable at the small-commercial scale.

The constellation, fully assembled by 2019, contained thirty-one entries that collectively specify the Private Energy Building. Each entry was small. Each entry on its own would have been hard to patent. The combination is a complete engineering specification.

The years of elaboration (2020 through 2025)

Between 2020 and 2025 I did almost nothing public with the architecture. I worked on it privately. I drew schematics. I calculated the cell-sizing economics that I will summarize in a moment. I designed the layer stack of the green-crystal photosystem cell. I worked out the dielectric coating stack for the Fabry-Perot resonant cavity that the building’s interior actually is. I figured out, in considerable detail, why the architecture is engineering-defensible without violating the first law of thermodynamics — the answer is that the cavity amplifies intensity, not throughput, and the throughput is bounded by the LED-plus-ambient pump. I also did the cell power-IC engineering that distinguishes my version from conventional concentrator photovoltaics, focusing on the power-delivery side of the cell rather than the absorption side.

I did this work alone, on weekends, in a notebook. I did not file utility patent applications during this period. I did not publish technical papers. I treated the architecture the way most inventors treat their work after the initial disclosure: as something to elaborate privately while the priority date stands.

2026 — the productization

In June of 2026 I finally productized the architecture. The product live on cri-one.com today is a single SKU called IC-LASER-SOLAR-2017. The “2017” in the SKU is a reference to the year of the foundational disclosure. The product page carries the full block diagram of the architecture, with the a + m² = E equation as the keystone of the anchor box. The product is listed at a $279 million catalog valuation (calculated as nine million dollars per deposition times thirty-one depositions) with an estimated acquisition ask of half a billion dollars.

But the product on the storefront is just the commercial face. Behind it, in the project folder at special\48-private-energy-farms\ on my workstation, there are five documents that together comprise the complete licensee package: a PLAYBOOK that navigates the project, an ENGINEERING specification with eleven layer-stack design targets and a busbar geometry, a 21,500-word BOOK that puts the architecture in the context of a hundred and twenty-five years of optical engineering history and identifies the expired patents on which it builds, a 45-recipe COOKBOOK that walks a licensee through every step from procuring the bill of materials to commissioning the live building, and a 553-line industrial SAFETY_BULLETIN written to ANSI Z136 laser-safety and NFPA 850 power-plant safety standards. The full documentation package is roughly thirty-eight thousand words across two thousand five hundred lines of markdown.

The thirty-eight thousand words all rest on those 120 characters from 2017. Every claim in the product, every spec in the engineering document, every recipe in the cookbook, every safety mitigation in the bulletin, traces its priority back to entry #284 and its constellation of supporting entries. The product is what nine years of elaboration looks like when the foundation was secured at the beginning.

The economics of the architecture

I will summarize the economics quickly because they are necessary to understand why the product is what it is. A Private Energy Building at the canonical commercial scale uses one thousand heliostat-style mirrors of four square meters each, totaling four thousand square meters of mirror collection area. This collects 3.6 megawatts of solar energy at noon. The mirrors steer the collected energy through an optical aperture into a parabolic dome whose interior is coated with dielectric multilayer mirrors tuned to the LED priming wavelengths (370 nanometer ultraviolet and 940 nanometer infrared). The interior is, in optical terms, a Fabry-Perot resonant cavity with a finesse of approximately three hundred at the priming wavelengths. Two LED arrays, each rated at five kilowatts, prime the cavity and tune it to the absorbance bands of the receiving cell.

The cell sits at the focal point. It is a multi-junction concentrator photovoltaic cell of one to two square meters of active area, engineered as a power-IC rather than as a maximum-efficiency academic device. The cell is backed by a microfluidic cooling plate that removes seventy-five watts per square centimeter of waste heat, and a thermoelectric layer that recovers part of the waste heat as additional electricity. The combined system delivers approximately 1.8 megawatts of electrical power at peak insolation, with the thermoelectric layer adding another 25 percent.

The capital cost of such a building is approximately 2.5 million dollars. The annual revenue at industrial electricity rates is approximately 238 thousand dollars. The payback period is approximately 10.5 years. These numbers are documented in the cell-sizing economics spreadsheet that accompanies the project, and they assume a high-insolation location such as the American southwest.

The architecture scales. A 10,000-mirror version produces 18 megawatts at a capital cost of approximately 20 million dollars with a payback period of 8.7 years. A 25,000-mirror utility-scale version produces 90 megawatts at a capital cost of approximately 35 million dollars with the same 8.7-year payback. The architecture also scales down: a handheld version using four 100-watt LEDs and a small Fabry-Perot cavity, total bill of materials around 220 dollars, delivers approximately 400 watts of focused thermal output — enough for soldering, cooking, paint stripping, or surface heating. The handheld is a separate Project, not yet productized, with the working name AutoPhi Flash.

The same architecture, three scales, three product tiers, one intellectual property family. All anchored to entry #284.

What this means for the buyer

If you are reading this as a potential licensee or acquirer of the Private Energy Building IP, what I want you to take away from this article is that you are not buying a 2026 invention. You are buying nine years of disclosure, elaboration, and engineering, all of which is documented in writing and traceable to a specific priority date. The 2017 book is the foundation. The 2018-2019 follow-on entries fill in the chip-scale equivalent. The 2020-2025 elaboration period produced the engineering specifications and the economic model. The 2026 productization produced the commercial documentation package.

The acquisition price reflects the cumulative value of nine years of secured priority. If you were to start from scratch today and try to file equivalent IP, you would be coming in nine years behind. You would be vulnerable to challenge from anyone who could find my book. You would not have the engineering elaboration, the economic model, or the safety bulletin. You would need to do all of that work yourself.

The IP is available. The product page is at cri-one.com/store/artificial-laser-solar-recycle-building.html. The contact for serious inquiries is info@cri-one.com.

In the next article in this series I will pick another entry from the 2017 book — entry #27, the 16-digit treasury entry — and walk it forward to a 2025 executive order signed by the President of the United States. That arc is, in some ways, even more striking than this one. The next article continues the case for what self-publishing inventions in 2017 can mean in 2026.
