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

(1/21) > >>

EEVblog:
Dave debunks the marketing claims of self-charging Nano Diamond Batteries in the first 10 minutes using their own material. The rest of the video is cream on top.
NDB Inc supposedly have a nuclear nano diamond self-charging battery that will revolutionise the energy industry and power electric vehicle and mobile phones.
TLDR; it's no better than existing 100uW commercial betavoltaic batteries, but has an added graphene supercapacitor in the AA package.The rest is marketing BS.

How could you honestly market a betavoltaic energy device? "Nanoamps until long after civilization collapses"? Sounds catchy.

When i hear "Our product will revolutionise the industry!" , i turn and run as fast as i can.

I got this sent to me yesterday by a friend. My reaction was:

"Be careful of the bullshit rays. Unlike Gamma rays this type of radiation cannot be blocked by lead. It seeps around the corners and penetrates everything. Extended exposure can lead to serious bodily harm."

However later I took the time to look around to see if this was actually a thing, other than marketing BS and this is what i found:

(To those who do not have access to it use sci-hub.tw)

If you forget the marketing it is actually an interesting read.

BrianHG:
If they were a penny each, and I could get them in better packaging, then maybe yes, buying 2500 units for 250mW continuous may have use if I can stick that into the area 1/4 the size of a shoe box, something like an old lantern battery.

Anything more than a penny means I'm better off with using a bunch of D cells and live with replacing them every few years or so.
