Electricity is becoming a matter of security, and not only for countries. Bring that logic down to one person and the answer changes. Someone who cannot make their own electricity ends up living the way somebody else decides.
That is a large sentence, so here is the small one underneath it.
I am one person in Seoul. No company, no team, no product, no funding. I did not study engineering.
I am starting with the smallest version of the idea that I can actually hold in my hand, learning the physics from zero, and publishing all of it. Including the parts that do not work.
The first product folds a solar panel and a battery into one piece to carry, and separates easily into two to use. Nothing on the market does both.
The bet is that one ordinary person building this in public, and showing the failures, is worth more than another company with a good looking website.
First question: does it work without a power plant. One panel a person can carry, measured and calculated before anything gets bought.
Find out what actually runs on it. A phone, a laptop, a small light. Start there and count.
Selling power directly to a neighbour is currently blocked by regulation in Korea. I treat this as a five year problem and keep notes until it opens.
The four rows below are my judgement, not established fact. But this judgement is why I started, so I state it as judgement and write it down as it is.
It rises from two directions at once. One is climate and conflict. Longer summers and winters mean heating and cooling run longer, and in places with conflict there are still people whose lives are cut short by unstable power. The other is national industry: AI and data centres, semiconductors, robotics, and healthcare. Healthcare in particular cannot stop for a single day.
No country can give up those industries. Falling behind there is a security problem.
You cannot double a country's electricity overnight. The only thing left is to divide it.
That pressure ends up on individuals. Usage gets capped, or prices rise, or both.
AI, data centres, robotics, semiconductors, healthcare. An individual cannot do any of this. That is the part a country has to build big.
Make what you use, use it easily, and buy or sell the difference with a neighbour. That is the part individuals can hold in small pieces.
Then the country secures the power its industry needs, and individuals hold a share nobody else controls. And once generation is scattered across thousands of places, one failure no longer takes everything down with it.
This is the single reason the sentence at the top is a physical possibility rather than a slogan.
Spun by water, by steam, by wind. Coal and nuclear both come down to boiling water to spin a turbine. Plants like that get better the bigger they are, so splitting them is a loss. Electricity has always belonged to large groups.
Light hits a semiconductor and electrons move immediately. No moving parts, no fuel, and no penalty for dividing it. A hundred panels of one square metre work exactly like one panel of a hundred.
So it can be cut into a hundred pieces and held by a hundred people. A water wheel the size of a palm turns nothing. A panel the size of a palm still works.
Individuals making the electricity they use at home. That is where this goes in the end. It is just not where it begins.
In August 2026 I sat down with an expert at the Seoul product development centre. I was told that in a country where the grid is as reliable as Korea's, household solar struggles to find demand, and he pointed me toward something portable instead. It was the opposite of my hypothesis, so I wrote it down exactly as he said it.
And putting solar on a home drags a lot of things along with it. Building rules, installer licensing, grid interconnection, subsidy paperwork. You get blocked by procedure before you get to build anything.
No permit needed, usable the day you buy it, and if it does not work you find out immediately. It is the fastest place to learn.
Right now you buy a panel and a battery separately and join them with a cable. One product did combine them, but its built in panel was so small it took days to fill, and reviews call it decoration. It is currently out of stock.
One piece when you carry it, two pieces when you use it. That is the first product.
Whether it sits in your hand or on your wall, what is inside is the same. A solar panel, a battery, and the circuitry that moves power between them. What works small can work large.
Prove the structure with the small one, then widen it to the home. The destination has not changed. It is the same three sentences at the top of this page.
Unfolded it is a panel and a battery. Folded it is one piece. The last step, trading with a neighbour, is drawn faintly because it is not legal yet.
Folded, the panel and the battery become a single object. One piece to carry, two pieces to use.
In order, and written down whether it works or not.
Read real measurements posted by campers, and go through reviews of what already exists. This part is done.
How many watt hours, filled in how many hours, under what weight. The shape only follows once these are set.
Model the join and release in 3D. The test is whether it works one handed, and whether it works wearing gloves.
What worked, what did not, and what I got wrong. There are already enough records that only include the good parts.
This space could have been filled with plausible case studies. Instead it holds only what is certain right now. The day the zero becomes a one is the first real event in this record.
0 built
Prototypes made so far. Nothing has been built yet
3 hours
Target time to fill 300 watt hours. A goal, not a measurement
1 person
People working on this. Looking for someone who knows circuits
The one combined product that existed took fifteen to twenty hours to fill. Three hours is the target set against that.
“You do not have to be a genius. If an ordinary person can do it with their own hands, then other ordinary people can too.”Why this record exists
Fix the target numbers. Model the join and release in 3D. Find someone who knows circuits.
Buy the parts as soon as there is money and build the first prototype. Publish the whole process including the receipts.
Put it in the hands of someone who will actually use it and listen to what annoys them. Neighbour to neighbour trading waits on the regulation.
Where I am not confident about a date, I have written that I am not confident. It moves with the money.
No. I have never studied electronics. So I write down the parts that people who know this already skip over. A record written by someone who does not know reaches other people who do not know.
No. No legal entity, no team. One person. NODOS is the name I keep the things I build under.
Panels and batteries exist, but you buy them separately and join them with a cable. One product combined them, and its built in panel was too small to matter. Combining them while keeping a panel worth using is the problem I am trying to solve.
I do not know yet. Once the parts are bought I will publish the receipts. Naming a figure before buying anything is a guess, not information.
Selling directly to a neighbour is currently blocked by regulation here. I treat it as roughly a five year problem. Until then only the making and the using.
You draw from the grid, exactly as now. This is a beginning, not independence, and it seems better to say so at the start.
This has nothing to do with what I am building now. It was made before the direction changed, so it sits down here instead of being deleted.
Putting solar on an apartment creates a fork: do you hang the module outside the railing, or stand it inside the window? Outside performs better but you have to get past building rules and the risk of something falling twelve floors. Inside is easy to install but the light passes through one more pane of glass.
Saying that costs you some watts means nothing. So here it is as something you can press.
Switch between outside the railing and inside the window. Change the glass type and the loss appears immediately. Use ＋ for more modules, the slider to move the sun, and drag to rotate.
These are calculated numbers, not measured ones.
I cannot install anything for you. I have no licence and no experience. What I can do is share everything I have found out, including the parts that turned out to be wrong.
