Every two years there is a new announcement of a betavoltaic battery, like using Carbon 14 to power it for 5000 years. They have very low power, lome 100mW, enough to power a watch but not a phone.
You propose using Helium 3, that has a shorter half life. My old phone got broken and when I went to the repair shop the owner noted that the phone was was like 10 year old and almost laugh.
So I think a shorter half life is good, but how are you planing to store the He3 without leaks? It looks like a nightmare.
PS: It's not a "Show HN" until we can try it. https://news.ycombinator.com/showhn.html https://news.ycombinator.com/showhn.html
- gus_massa 6mo agoToo late to edit: I just notice it's H3 instead of He3. H3 is easier to store. How are you planing to store it anyway?
- joshuashelvin 6mo agoI realized my math on how many Ci of tritium the device would contain is way off. I am pivoting. And I won't do Show HN again until new device is in hand.
- gus_massa 6mo agoYou can still make post that are not "Show HN"... It's an interesting idea, but I'm wondering why nobody thought about it before. Perhaps the problem is in the storage capacity you noticed, perhaps the price or perhaps any other of the nasty details of hardware. Good luck in your new project.
