## Idea

A day inside an iron lung
Helps readers understand how an iron lung supports breathing and how daily life unfolds around the machine through Martha Lillard’s day.

## Product concept

When readers first encounter an iron lung through Martha Lillard’s story, they can open a life-size interactive page on their phone. Users first drag the person into the cylinder, then try changing the air pressure with a slider. The page shows with each action why the chest expands, why the head must remain outside, and what happens during a power outage. The interface then shifts to “Spend a day inside,” where users handle eating, looking in a mirror, talking with visitors, and maintaining the equipment in sequence, with each step drawing on specific experiences from Lillard’s life. They receive not a score but a shareable “What I misunderstood” explanation card. Unlike a 3D display that treats the iron lung as a curiosity or antique, this experience uses renewed attention to Lillard and polio to make the mechanical principles and a person’s daily life visible at the same time.

## Why now (backed by facts)

Martha Lillard, the last person in the United States with polio still using an iron lung, died on June 26, 2026, at age 78. After related coverage was published, searches for “iron lung” in the United States reached about 20,000+ over roughly one week, an increase of about 200%. This means many readers encountering an iron lung for the first time are simultaneously looking for its mechanical principles and Lillard’s own experience. The moment is suited to an immediate interactive explainer that treats the person’s daily life with respect.

## Direction (model inference, not independently verified)

Target user: General readers who first click on “iron lung” through news, obituaries, or social platforms, plus teachers and students who need a quick explanation of polio and ventilator principles. They open it when they wonder how a person breathes and lives inside one.

Minimal entry point: Build a roughly three-minute mobile web page for the first version. Users drag an air-pressure slider to see the chest change with negative pressure, then complete a manual breathing-maintenance scenario after a power outage. Embed a short quote or fact from Lillard’s experience at each step.

The strongest case against: The strongest case against this is that event-driven search interest may be brief, while accurately reconstructing Lillard’s daily life would require interviews, archival permissions, and medical review. Production costs could exceed the sustained demand that a short-term interactive page can capture.

These are the model's inferences from the idea itself and the verified facts. Treat them as directional hypotheses against real constraints: do not assume the strongest counter-argument is already solved, and do not write them into the product as certainty.

## Punching above weight (model inference)

Build an interactive explainer around rising “iron lung” and “Martha Lillard” search intent so news reports, obituary pages, and teacher resource pages can cite it directly. Design the closing “What I misunderstood” card as a factual summary suited for sharing on social platforms.

## Competitors & gaps (model inference)

- Polio's Last Mile: Offers a browser-based interactive 3D polio experience that does not require a headset, but it currently does not support mobile. Its focus is the public health history of polio eradication, not connecting the mechanics of an iron lung with daily life through one user’s day.
- Science Museum：The Iron Lung: Explains how an iron lung works through text, images, and collection materials. It is useful for reference, but does not let readers adjust air pressure, handle a power outage, or experience the user’s daily life through an interactive narrative.

## How it makes money (model inference)

Charge museums, science education institutions, or public health organizations a one-time customization and licensing fee. Also offer an annual institutional version with course materials.

## Trend background

Theme: Martha Lillard and polio through the iron lung user’s experience
Trigger query (original English): iron lung
Approx. search volume: 20000+ (approximate)
Approx. increase: +200% (approximate)

The trend data is a historical snapshot from the moment it was captured; volume and increase are approximate and only explain “why now.” Do not write them into product copy as precise market numbers.

## Deliverables

- Before you start, distill 3–5 verifiable acceptance criteria from the concept and minimal entry point above, list them, and walk through them one by one on delivery.
- Ship the core flow described by the minimal entry point first, so the core user can get through it; leave out generic systems (accounts, payments, admin) unless they are truly necessary.
- Do not show unverified market numbers in the UI or API.
- Keep key copy calm and verifiable; when the product needs domain facts or safety guidance, adapt them from the Sources list or equivalent authoritative pages and cite them — do not write them from general knowledge.
- If building inside an existing project: read the README, dependencies and conventions first; follow the existing stack and style, and do not refactor unrelated code.
- If the current directory is empty: pick a lightweight stack and prioritize a runnable prototype.
- When done, explain what changed, how to run it, and how to verify it.
- Ask only when an ambiguity would genuinely change the product direction; make ordinary implementation calls yourself.
