Diamond Nuclear Batteries Are Forever… Sort Of

September 11, 2019

Since the early 1900s, researchers have been
working on ways to turn radioactive material into an electric current that lasts.. for
decades. Yeah, that’s right. We’re talking about nuclear batteries! This class of batteries is known as betavoltaics,
and they’re powered by the beta-decay of a radioactive material—hence the name. Beta particles are basically just high-energy
electrons, so setting a beta-emitting material up next to a semiconductor is virtually all
you need to get an electric current in motion. Though their power output can be pretty low
(we’re talkin’ less than an AA battery), they last as long as it takes the material
to decay. And since radioactive materials can have half-lives
of centuries to millennia, that means batteries that could last for decades without any noticeable
power loss. As an aside, betavoltaics are different from
the Radioisotope Thermoelectric Generators (or RTGs) that NASA uses for space missions. Those are powered by the HEAT of radioactive
materials, like plutonium, instead of beta particles directly—and are also sometimes
referred to as nuclear batteries. But betavoltaics can be made smaller and safer
than RTGs, and with the incredibly long lifetimes that nuclear promises. Back in 1954, the Radio Corporation of America
announced the development of their first betavoltaic battery. And at the time, it was a big deal. RCA imagined them being used in wristwatches,
hearing aids, and radios. And in the February 1954 issue of LIFE magazine,
RCA even compared their invention to Edison’s lightbulb. But, while lightbulbs are literally everywhere,
I would wager you probably don’t own a device that runs on nuclear batteries. Today, betavoltaics are mainly used in deep
space and military applications- far away from the average consumer. And there are a lot of factors involved as
to why that is, but a big one is safety. Like I said before, betavoltaics are safer
than other nuclear power systems, but some beta-emitting materials can still be pretty
dangerous. For example, RCA’s prototype from 1954 ran
on Strontium-90, exposure to which can cause leukemia. And even though their battery was coated with
radiation blocking materials, it still probably wasn’t the safest thing to hand off to anyone
walking down the street. But we’ve come a long way! In recent years, several research teams have
been looking for a way to safely harness the power of betavoltaics. And one team at the University of Bristol
is making one out of DIaMonDZ! We talked to Dr. Neil Fox, who’s developing
a new prototype made out of carbon-14, a naturally-occurring radioisotope that’s in our atmosphere and
in all living things.. It’s also a common nuclear power plant waste
material. [Dr. Neil Fox ] “So our research has really
been about looking for ways to repurpose that material, so that it effectively can be recycled. And carbon-14 is a particularly attractive
one because it’s not really on the list of really nasty radioisotopes. It’s a fairly, friendly material to work
with..” Fox’s team isolated Carbon-14 and synthesized
a diamond out of it. In doing so, they created a radioactive diamond
that could produce an electric current(!!). Granted, it’s a small one- not enough to
power your phone. But it IS enough to power smoke detectors,
emergency signs, IoT devices, sensors in jet engines or deep sea cables, and even e-readers. And it could power all of those things for
decades, without needing to be replaced. As for safety?–
[Dr. Neil Fox] “It is totally safe because we’re talking about a device which is made
of diamond. The radioactive part is actually diamond as
well And all of the radiation, all of the power of the device is completely absorbed
by the diamond structure around it.” But perhaps one of the most impactful applications
of this battery is for medical implants. Today, they largely rely on lithium ion batteries,
but those have limitations. [Dr. Neil Fox ] “I mean there’s some little
girl, she has to have some fairly intrusive surgery on her hearing implant every 26 days
they have to change the battery on this thing… We’re constantly getting emails from people
who’ve got all sorts of implants…So if you can provide them with a solution where
it’s fitted to last for decades, even for a lifetime, that’s got to be worth something.” So, today’s nuclear batteries might not
be what scientists imagined back in the 1950s, but a nuclear diamond battery that could go
inside you? Still pretty dang cool if you ask me. For more on the science of batteries, check

topics you want us to cover! As always, thanks for watching, and I’ll

    Reason is carbon tax because the rich Fiat money will lose their wealth so they keep destroying the earth because fossil fuel is a protection of earth’s core from extreme the inner heat and earthquakes that have increased to almost 1000 each month around the world 🌎.

    They can also do energy tax but there is no one to claim Nicola Tesla. If America does that their lie will be exposed so they know it but they tried thru Barak Obama but his lies did not go so far as well.

    Ok so what about older style cellphones? It seems we got spoiled with all our high end gadgets. Smart phones are great, and have many uses, but I am sure a lot of people would go for a low tech cellphone that can last decades without charging.

    Also what about a battery pack that slowly recharges itself when not in use. Sort of a hybrid technology? You can still "fast charge" by plugging in, or slow charge if you have no close by power source.

    Or a cellphone with a high and low power mode. You always can make a call, but you can use gps, internet, etc, by plugging it in or letting it charge with this, slow charge mode?

    "without any noticeable power loss"?? That is not right at all. Radioactive materials tends to decay half of its mass every "x" year and this amount is defined as half life(Just like stated in the video) of the material. If we think logically, this means every time the material loses its original atoms' mass in their next half life the output material will be getting lesser and lesser. So the Beta particles that will come out to provide current won't be sufficient after an amount of time even after the matter experiences its first half life period.
