Tritium Nuclear Battery Project Kickoff


Build an energy harvester to collect latent energy from tritium vials. (GitHub Repo)
I have a deep belief that this latent energy if captured efficiently and properly harvested can be put to good use. I understand that solar cells are incredibly inefficient and many things that I’m doing here are not perfect. This project is to only explore science.
Maybe the next person can learn from this repo and my research and improve. 

Tritium Vials and Spheres


Photovoltaics and Betavoltaics, what we are building is a much safer version of this where instead of using Isotopes of promethium, we are using tritium an isotope of hydrogen, a beta particle emitter. This concept 'Tritium Radioluminescence' is also known by some alternate names such as 'Gaseous Tritium Light Source (GTLS)' or 'Beta Light'.

The science is very simple, Tritium an isotope of Hydrogen decays into Helium 3 via beta decay with a half-life of 12.32 years. Electrons carry 5.7 keV of energy and penetrate only 6mm of air. (insufficient energy to penetrate human skin) Tritium beta decay colliding with phosphor emits a very low-level glow in the visible spectrum.

Tritium Buying Guide

How to get your hands on some tritium? This guide will provide resources and what to look for when purchasing tritium. With the shipping disruptions of 2020, prices are all out of wack and should normalize.  Note: This guide will not cover the legal aspect as each country has its own laws and regulations. To learn more about the luminosity and spectral intensity of tritium vials, read my post here:  True Brightness of Tritium Vials   Spoiler: Tritium Safety Isotopes should be treated with respect, not only for the safety of yourself but also for the safety of others. The average amount of tritium inside a tritium vial has been observed as such: 3mm x 22.5mm tritium vial is roughly 0.1 curies (3.7 GBq) 5mm x 150mm tritium vial is approximately 1.8 curies (66.6 GBq) Is That Dangerous? It would be inappropriate to say anything other than 'Yes'; however, the risk is highly negligible. The EPA  touches on how tritium can enter and be processed through your body. Tritium is a low-ene

True Brightness of Tritium Vials

How Bright Are Tritium Vials? Describing the brightness of tritium can be difficult. People observe the luminescence differently and have differing opinions comparatively. So how can I  genuinely   share the luminosity of tritium vials and rank them?  Below I will showcase my findings using different techniques to put things into perspective. First things first, let's recognize the charting available today; maybe you have seen these or some variation of them:   These images are well over 10 years old and have several variants, some poorly photoshopped floating around. Let's make it our objective to reinvent this chart. Essential to take note, the charts above mostly agree on one thing, the ranking of 'output/yield' compared to each other by color. Spoil Warning , my results don't align with the common consensus listed above.  Take Amazing Photos of Tritium: Looking to

DIY Spectrometer

Tritium Vial DIY Spectrogram To make the best decisions regarding solar cells, understanding the emission of Tritium Vials is critical. A lab-grade spectrometer can cost $5k-$10k, a bit out of budget for this project. Instead, building a spectrometer isn't too terribly difficult. Consumer-grade tools are available that enable the home enthusiast to construct an estimated optical spectrometer that, for general purposes, can be used. The range of this DIY spectrometer is easily between 40nm to 700nm.  To learn more about the luminosity and spectral intensity of tritium vials, read my post here:  True Brightness of Tritium Vials   Spoiler: How to Build this Spectrometer? Credit, where credit is due, this 2016 project by Tony Butterfield,  is the root for this idea; the physical form was replicated to the best of my ability with some improvements.  The code was initially analyzed  and determined to be a guideline rather than a commitment .  The CMOS sensor and features in
