In all of history, what product has created its own value and paid the cost back, the longer you kept it?

Home solar? A ceiling fan? A countertop plant grower?

We dare say we turned a space of consumption into a base of production.

Engineering proof

Cross-verified by nine global AI models.

Zero incremental power draw (ΔP = 0) and the effectiveness of the cleaning-free circulation were independently reviewed and simulated as engineering problems. For the sake of trust, the full transcripts of every AI conversation and review are published openly.

Core Technology · Zero Power

We don't create energy. We reallocate it.

An ornamental fish tank already runs a 20W circulation motor. As a waterwheel grinds grain with falling water, LJR takes the potential energy those 20 watts have already created — and cleans, humidifies and deodorizes the room with no power of its own.

Core Technology · Zero Cleaning

No one scrubs it. The current and the roots do the work.

Still water grows moss; running water does not. Waste does settle, but a person never has to remove it. The dual-tank flow carries it out of the inner tank and the surplus leaves by overflow, descending the outer wall as a film. The roots of the vegetables and flowers above take up and purify the nitrogen, and seven filtration stages return clean water to the ornamental fish. All a person does is replace the filter box and top up the water that has evaporated.

Seven stages of filtration — purifying the water.

Licensed Technology

Technology added into the table.

LJR's own core technology is substantially power-free operation. On top of it we license and mount two technologies developed as separate businesses. All three operate independently.

Wellness features are for reference only and are not a medical device.
Independent Proof

Nine AI systems, one conclusion.

Nine different AI systems independently reviewed zero incremental power (ΔP = 0) and the cleaning-free circulation by pure engineering simulation. Every transcript is published as it is — questions included.

National certification is in preparation. No category yet exists for a table that grows food while replacing household appliances, so published AI engineering verification is the smallest evidence LJR can offer. A single AI simulation can hallucinate, so the same questionnaire was put to nine of them, and what follows is the predictive verification they produced. Until a category exists for a table that grows food and cleans air at once, open engineering review is the most honest evidence we can offer.

{{ a.i }} {{ a.n }}
Power-free analysis

Substantially power-free, by potential energy.

Each of the nine systems was given the same questionnaire — film dimensions, room conditions, the seven filtration stages — and asked what share of a humidifier, an air purifier and a deodoriser the water film replaces. Ranges were converted to midpoints. Nothing was discarded.

This is a plain aggregation of what nine AI systems derived from their own physical and thermodynamic models. It is not a certified test report. Real performance varies with environment, maintenance and how the table is run. We publish it because it is the most honest evidence we currently have.
Cleaning-free analysis

Substantially cleaning-free, by circulation.

Still water grows moss; running water does not. The reason an aquarium needs scrubbing is that its water sits still. LJR never lets it settle. The same nine systems were given one questionnaire — 15 LPM flow, the rising vortex, seven filtration stages, 270 heads of lettuce in cultivation — and asked to assess four things: physical discharge, whether water changes become unnecessary, filter performance recovery, and the annual reduction in cleaning.

All figures in percent. Discharge = waste carried out of the inner tank; No change = degree to which water changes become unnecessary; Filter = performance recovered by partial replacement; Overall = each system's own confidence in permanent cleaning-free operation. The final row reproduces the averages stated in the source report, which may differ from the arithmetic mean of the nine values shown. The source gives no average for physical discharge, so that cell is left empty. Gemini's water-change figure was given as a description, “very high”, not a number.

Carbon analysis

A stand of pines, in one table.

One pine absorbs about 6.6kg of CO₂ a year. Given the same power saving — 5,387.4 kWh — each of the nine systems applied its own grid emission factor and its own assumption about running hours. We publish the whole spread rather than the number that flatters us most.

Pines = CO₂ reduction ÷ 6.6kg per tree per year. Factor = the grid emission factor each system applied, in kg CO₂ per kWh. The differences between the nine come almost entirely from that factor and from assumed running hours, not from disagreement about the structure.

How it is calculated
{{ f.k }} {{ f.v }}

We propose the average of roughly 347 to 367 pines as our stated figure, and publish the full spectrum from the most conservative 114 to the most optimistic 453. Real effect varies with how a household lives — ventilation, heating, climate and maintenance. This is an engineering estimate, not a certified test report.

To state it plainly once more: the three analyses above are engineering values derived by AI, not certified national test reports.

Products

Six tables and one large tank. One principle.

Function came first.

All six are real, built to prove the principle. We put the completion of the mechanism ahead of the finish, so the build is crude — but the function is finished.

With AI-assisted design, we now build refined, simple forms — and any structure a space asks for.

And what those functions return each year.

Two returns, counted separately and conservatively: the electricity the table no longer spends, and the produce it grows. LJR's own consumption — motor 24 hours, grow lights 16 hours — is subtracted in full.

Electricity at ₩150/kWh; produce at ₩1,500 a head, deliberately below the ₩2,500–3,500 market price. Substitution rates are the effective average of nine AI systems. An engineering and market estimate, not a certified test report. Full workings are in each model's card on the Products page.

One table changes a room. A million change a grid.

Regulation

Twenty-three countries already require it.

Public bodies and large corporations in these markets are legally obliged to reduce and disclose emissions. LJR is not asking them to choose an environmental product — it gives them a quantified figure for an obligation they already carry. Each card sets out the statute, the duty it imposes, and how our published data answers it.

{{ g.t }}

Statutes and article numbers are quoted as published by each government. Our figures are the engineering estimates set out on this site, cross-checked by nine AI systems, not certified test reports. Partners are asked to confirm the current text of the law in their own territory before submitting to a tender.
