EEVblog #1333 - Nuclear Diamond Self-Charging Battery DEBUNKED!

EEVblog did a debunk of this at [this video] Basically, the power density of these are so low that they're useless for most applications. Sure, it might last 28,000 years, but you're only getting 100 microwatts from a battery the size of a normal AA battery.

It is not clear that they have a real working prototype. The current is very low, only 100uW, and there are similar batteries made with tritium. More info in a video by EEVblog eevblog had a good video about this product: [this video] Also, there is a calculation of the low the maximal current per kilogram in [link]

Where is innovation and efficiency ? To me it smells like [this video] and all about patents, marketing and money burning, but I don't know as much as these professors do so maybe I am wrong.

This nonexistent product has been discussed and debunked here before. Here's EEVblog's take: [this video]

To add to the sample size of n=1, a few months ago, there were many articles about “nano diamond” batteries that will supposedly solve the radioactive waste problem. Dave Jones of EEVBlog debunked it pretty quickly: [this video] Basically, every few months, a company comes out with claims that battery tech or e-waste has been revolutionized , but it’s always a bunch of bunk claims made using a multitude of weasel words.

It is not clear that they have a real working prototype. The current is very low, only 100uW, and there are similar batteries made with tritium. More info in a video by EEVblog eevblog had a good video about this product: [this video] (it's old, but I can't find any evidence of improvements.) Also, there is a calculation of the low the maximal current per kilogram in [link]

Why are you interested in this? If it is for anything other than very LOW power (microwatts), you're going to be disappointed. It is essentially a beta emitter hooked to a capacitor via some electronics to handle voltage conversion. The thing is the beta source is use it or lose it, and very low power. If you scaled this up to power a Tesla, it would be a nightmare, as it would need to dissipate the full power the car requires, all the time, or it would melt down (aka Fukashima) For a longer debunk - [this video]

It was heavily discussed a few years ago, for example in [link] They last for a log time, but the important detail is that they have very low power, like 1mW with the size factor of a normal battery, so you need like a dozen for a (old) wrist watch and s few hundred to turn on a led.

These are woefully underpowered for consumer electronics and always will be - only really useful for maintaining volatile memory. This idea has actually been debunked more than once. [this video] [link]
