Self-healing potassium batteries: A cheap, long-life rival to lithium

Having had to undergo extensive cardiac testing has exposed me to the latest diagnostic equipment. Being a tech head, I naturally asked questions about the capabilities...consensus was that the next huge thing is the AI applications coupled with the various imaging technologies, all in real time.

Those are amazing and I had looked at them before. We are still at the targeted stage though with only a small number of people using these technologies.

I believe they will become much more widespread in the future and it will be a great thing!

I’ve got 3 of their 100 amp hour batteries, and can’t be more impressed with them

I am not much of an investor and have no qualification to give investment advice, but I am so convinced this is true that I will be investing in these companies when this technology becomes clearer in the next few years.

I have said for years that technology will have to fix health care and I believe it will. Millions of people are wearing smart watches that record and report all kinds of data that will help.

“We have 3 100 amp battleborns on the sailboat. May one day add a 4th when we can get some more solar installed. Work great! Also cut weight on the boat by about 1/2.”

Thanks for the replys. Will be ordering (paying for) a small trailer this week, once it arrives 2) 100 amp BB will be installed with two 50 watt solar panels. Seems like an impressive company!

Nuclear batteries have been around for awhile.

Voyager has been going strong since 1977. Better than the energizer bunny!

We’ve 660 watts of panel right now. If we can figure out where to put another 2 to 3 hundred watts of panel up on the bimini, we will (as well as having the ready cash for it).

The Cap’n points out you should have a 2 to 1 ratio of watts to amps. You will need a good solar controler too. We’ve a Victron. Don’t skim on this part either. And make sure you get one big enough for your needs.

We run a fridge unit, several laptops, lights, phones, a small TV and the nav stuff off the batteries. If we have a run of bad weather we have a small Honda Generator (2200e) we can plug into the shore power port to keep us going. We plug in occasionally when we are in a marina, but, for the most part, we anchor/mooring ball out and have to be self sufficient.

The batteries a very light too. When we bought the third one (two just wasn’t enough for our needs), we had it delivered to a marina and the Cap’n picked it up and carried it to a cart. Folks thought she was a superwoman or something. And you can put them in any orientation. We have one laying on it’s side. No room other wise.

“...And you can put them in any orientation. We have one laying on it’s side. No room other wise.”

Thanks, I did not know that.

Buying a really, really small trailer that barely has room for solar panels (2 trimmed down 50 W panels will fit - barely).

Great info - thanks a bunch!

Enjoy your radioactive bananas!

Voyager uses a thermoelectric pile. Plutonium 238 oxide generates heat which a series-connected thermocouple device converts to electricity. Provides high power output over decades.

There are direct conversion radioactive battery which directly collect emitted beta (electron) or alpha (helium nuclei) particles to generate a high voltage. Typical small power output , but sustained for a very long duration.
