Yeah, great, but I had the greatest scare of my life at 2:09, because I'm using headphones and I unexpectedly heard someone talking right behind my back, slightly to the left. I'll keep on watching later.

Researchers are developing a new battery powered by lab-grown gems made from reformed nuclear waste. If it works, it will last thousands of years.

IN THE SUMMER of 2018, a hobby drone dropped a small package near the lip of Stromboli, a volcano off the coast of Sicily that has been erupting almost constantly for the past century. As one of the most active volcanoes on the planet, Stromboli is a source of fascination for geologists, but collecting data near the roiling vent is fraught with peril. So a team of researchers from the University of Bristol built a robot volcanologist and used a drone to ferry it to the top of the volcano, where it could passively monitor its every quake and quiver until it was inevitably destroyed by an eruption. The robot was a softball-sized sensor pod powered by microdoses of nuclear energy from a radioactive battery the size of a square of chocolate. The researchers called their creation a dragon egg.

@Davros , I guess now it's your turn to post a BUSTED video about this.
ps: radioactive batteries dont hold your breath they dont have the power output and if they did they would be lethal
Edit: Of course the conclusions in this video arn't necessarily correct.

The problem with radioactive batteries is always about waste management. For example, nuclear powered pacemaker was a thing about fifty years ago. Some were powered using Pu238, which has 88 years of half life, thus they don't have to be changed over its lifetime. However, the problem is that after the patient dies, it will have to be removed, otherwise it could become a radioactive pollutant. Unfortunately, people were worried about if anyone with such pacemaker died in a fire or an airplane crash or similar accidents, it could inadvertently spread radioactive materials around. Along with better battery technologies, nuclear powered pacemaker was no longer used (it's still in some patients, one woman lives with her nuclear pacemaker for more than 30 years).

A lengthy, detailed read on the subject.
More news related to lab-grown meat:
Some of the vegetable alternatives are quite good, already. Last week I ate a 100% vegetable hamburger that tasted almost like a beef one. Crazy.

Exclusive: At a ‘test restaurant’ in Israel, the meat is grown in vats behind a glass screen. Could it be a taste of the future?

A PhD in genetics might seem like an unusual requirement for the role of head chef. It makes more sense when the man running the kitchen is not just in charge of frying your chicken burger – he created the meat himself.
“This burger takes something between two to three days to grow,” says Tomer Halevy as he chops red onions, iceberg lettuce and avocado. He proceeds to batter what appears to be a strip of raw chicken before dipping it in breadcrumbs.
...
The breaded patty is deep-fried in oil, before being placed on a sweet brioche bun, flavoured by wasabi and chilli mayonnaise, with a side of sweet potato chips. Similar to many chicken burgers, it breaks and flakes when pulled apart and is extremely tender. It tastes, at least to this reporter, like a chicken burger.

What, nobody mentioned the folding accomplishment yet? This is a Nobel in progress.

there are a lot of bs going on in this economy. Apparently the industry that produces plastics is too powerful, too big and amasses huge profits, whereas turning to alternatives is comparatively more costly because they are very very young and they cant enjoy economies of scale that the plastics do.
I avoid plastics as much as I can, specially in food preparation/storage, since it may release harmful chemicals. It's not like there are no reasonable alternatives.
So, things like this are great!
Add the fact that the majority of the population is having financial difficulties and thus rely on the cheaper products, and the economic system shoots itself on the foot because money determines what should be produced and not what needs to be produced
They will be built in a way that will make it easy to replace them, I guess.

I'm sure he hasn't, since it's literally nothing to do with Tesla.
To your point on replacement, I'd imagine you're screwed if your structural battery car has seen significant charge degradation. You might get to keep the wheels and seats. The fact that it's low energy density might actually help provide a longer lifespan though.
Current batteries used by automakers are fairly recyclable and batteries recycling is economical (which is a key factor in sustainability). It would be rubbish is structural batteries weren't and they saw wide adoption.
Can't see that happening anytime soon for cars though. Putting aside this is a University fishing for more funds and they're not at the right energy density yet... mass production is just too complex, with long lead times.
It's an interesting cost trade on eventual adoption. Cheap mass produced cells + very mature body manufacturing processed verses rolling both processes together.
speaking of batteries I dont know if this was mentioned here, it was all over the news a few months ago

though unlike a lot of battery promises that over the years fizzle out, I think this is gonna be one that sticks
