battery that lasts 5,700 years without recharging

Yes, great but the UK will not profit from it because we as a nation have no idea how to commercialise inventions yet we have the brains to invent.

A battery that lasts 5,700 years without recharging has been created in the UK

Imagine a battery that lasts 5,700 years without needing to be recharged. This might sound like something straight out of a science fiction novel, but thanks ... Continue Reading →

Yes, I had a Nokia 3210 back in the day so we know that technology existed.

Can't imagine the profit would be massive anyway. It has only very very selective usage as the output of the battery is very very low. As the article says it can only be used for things that would require an incredibly small battery, smaller than those CR25 flat disc ones.

Dammit, I came in to say the same, albeit my 5110 was better

Who on earth keeps a telly that long for the remote battery to last the distance

 

[wolfie138]

until they've tested it that long they shouldn't make the claim

Oh look, it's the battery that lasts forever story, again.

Mmm I was just thinking about how I need some batteries which put out 1 millionth of a watt but last for thousands of years.

We've had extremely long life batteries for a very long time.

All you need is for it to be powering something with a tiny power draw.

For example: https://en.wikipedia.org/wiki/Oxford_Electric_Bell

185 years and counting.

This is just a variation on RTG devices used on spacecraft, though they use plutonium or uranium. But how much power can it deliver?

Solar Roadways is where it’s at.

Can make already one last millions if you don't mind it being a bit radioactive

Perfect for that alarm clock set for 3am you've hidden under your ex's floorboards when you move out after finding she cheated

So practical

This article just states "low levels of power", but the listed uses states pacemakers and watches, so likely double digit micro-watts.

Thing is, who's actually going to wait around long enough to find out?

Love it!

Yup was going to say it has to be a radioactive source, Carbon-14 decay, its got to be in milliwatts at best more like microwatts

Why? The radioactive decay rate is a known value, so the battery "life" is accurate.
