Nuclear Batteries
Nuclear Batteries
Found on the Scrutineers FaceBook page: a self charging battery that draws its power from nuclear waste:
https://newatlas.com/energy/nano-diamon ... VG0tZdInGM
I has me doubts but I'm not an electronic engineer so I don't know what's possible and what isn't.
I suspect the nuclear waste bit (RADIATION!!!) will make it a hard sell even if it works.
And why the f.ck do techno-nerds feel the need to boast of "disrupting" industries? When did this become a thing?

I’m sure there was a story on these lines last year, or maybe earlier this year, from the University of Bristol.JQH wrote: ↑Thu Aug 27, 2020 7:52 amFound on the Scrutineers FaceBook page: a self charging battery that draws its power from nuclear waste:

Compare "The actual amount of carbon-14 in each battery has yet to be decided but one battery, containing 1g of carbon-14, would deliver 15 Joules per day. This is less than an AA battery" with "Its NAnO-diAMoND BaTTeRIes WilL aBsOLUtely uPEND thE eNErGY equAtion, actiNg LiKE tIny nUcLear geNeRAtOrs.

Re: Nuclear Batteries
1 g of 14C seems like quite a lot of radioisotope in one place, if you fancy handling this thing in any practical setting.
Re: Nuclear Batteries
My literally back of the envelope calculation is that C14 produces ~1mW/g
So to power a car you'd need about 40 tonnes of the stuff.
Clearly the claims being made are somewhere on the spectrum between techno=b.llsh.t and outright fraud. Certainly will be the latter if they start seeking investors.

Re: Nuclear Batteries
2017 then. Time flies. Anyway, yes I remember it being touted as an ideal way to power satellites and things that don’t necessarily need much power but are really hard to recharge/replace the batteries in. Not for cars where neither of those things are true.shpalman wrote: ↑Thu Aug 27, 2020 11:36 amCompare "The actual amount of carbon-14 in each battery has yet to be decided but one battery, containing 1g of carbon-14, would deliver 15 Joules per day.

Thermoelectric generation is spectacularly inefficient in almost all cases (hence the desire to generate electron-hole pairs in a semiconductor directly as in a solar cell*) although in space you may be able to radiatively cool the cold side to quite a low temperature.
Juno went to Jupiter with solar panels.
* - solar cells also get less efficient as the intensity of light drops, since photogenerated carriers are more likely to get trapped at defects whereas in the case of high intensity illumination the defects get saturated. This is why "concentrator" cells are a thing - they focus a large area of sunlight onto a smaller area of cell.

Re: Nuclear Batteries
Has anyone actually demonstrated bipolar transistors in diamond yet? I can find reference to field effect transistors on a diamond substrate, but I don't think that is what is required here.

Thanks, all I could find were descriptions of their advantages, in the future tense.

Re: Nuclear Batteries
A few years ago, some over-enthusiastic middle-ranking doctors were trying to tell me that I might need a pacemaker. (Fortunately, I got one of the final-year med students to talk to the consultant cardiologist, who told the MRDs to f.ck off.) While googling to see what delights awaited me, I found that if you have one of those things, they have to cut you open again every so many years to change the batteries. If they could make one that lasts 50 years it would save a lot of hassle.

Like most jokes based on filmed entertainment of the past 20 years, this whooshed right over my head until I googled.

Or fit a USB socket between a couple of ribs? Could use it to down load data, upgrade firmware and so on too.
