Proton-Proton Chain Fusion 3D Explorer vs alternatives
Proton-Proton Chain Fusion 3D Explorer walks through all 3 real reaction steps in the browser, one at a time - a static textbook diagram wins for a single at-a-glance summary; a full physics simulator wins for computing tunneling probabilities and reaction rates from first principles.
| Option | Strength | Access | Trade-off |
|---|---|---|---|
| Proton-Proton Chain Fusion 3D Explorer (this page) | Step-by-step reaction sequence with real MeV values per step, in one 3D scene | Free, in browser | Teaching approximation; does not track individual particle identity or model reaction-rate physics |
| Static textbook diagram | One at-a-glance summary of the whole chain | Free/paid textbooks | No interactive step sequence or animated ejecta |
| Full physics simulator | Computes tunneling probability and reaction rate from first principles | Specialist software, often paid or research-only | Steep learning curve; not built for a quick browser lesson |
Key published figures
| Figure | Value |
|---|---|
| Step 1 (p+p → d), x2 per chain | 1.44 MeV |
| Step 2 (d+p → He-3), x2 per chain | 5.49 MeV |
| Step 3 (He-3+He-3 → He-4) | 12.86 MeV |
| Net full chain (4p → He-4) | 26.73 MeV |
Start with the step-by-step guide or when to use. Open the Proton-Proton Chain Fusion 3D Explorer.

Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
