The aluminum-air battery has made headlines on the promise of giving a car up to 1500 miles of range, which would be amazing. But there's one big catch - you can't recharge it. Today we talk about the pros and cons of the aluminum-air battery, how it works, what "mechanical charging" is, and whether there's a real case to be made for their widespread use.

Here we go again. I recently covered the Victorian Era but today I want to point out the incredibly weird health and beauty practices that Victorians were into back in the day. As I say in the video, Victorian medicine was a mix of terrible old ideas and terrible new ideas, from people drinking radioactive water to eating ground-up mummies our transition to the modern medical system we see today hit some interesting bumps in the road.

We all know you need oxygen to live. But why? What happens to oxygen in our bodies? Why does it keep us alive? And maybe most importantly, why does it slowly kill us? In today's video, I explore the process of respiration, how it's weirdly similar to fire, and why we rely on one of the most corrosive elements in the universe to survive. It gets weirdly existential. See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info ....

With the Inspiration4 mission in the books, hot on the heels of Blue Origin and Virgin Galactic launching their first crewed missions, we've seen a bit of a backlash against this new space race. So today I just wanted to share my opinion on why space travel is important and the framing we've seen around these flights and these companies is misguided. All opinions are mine (as of this recording anyway). Disagreements welcome. See Privacy Policy at https://art19.com/privacy and California Privacy ...

The Victorian Era was an age of new discoveries and technologies that changed everything about the way we live. It basically created the modern world as we know it.

NEOM is Saudi Arabia's tentpole project in their Vision 2030 initiative to help move the Kingdom away from an oil-based economy and rely more on technology and tourism. It has some ambitious goals, like being 100% sustainable, moving all transport underground, and even glowing beaches. But the most noticeable thing about the project is the fact that the city will lie on a 100-mile line serviced by a hyperloop-style high speed train system. But is it all it's cracked up to be? Let's take a look. ...

With Artemis 1 stacking right now and the first launch planned by the end of the year, the moon is getting more attention than we have seen since the 1960s. The plan this time is to stay in a permanent moon colony, supported by mining operations on the lunar surface. But what could we mine there? And why will it be necessary for our future moon ambitions as well as interplanetary travel? There's gold in them there craters. Let's take a look.

Carl Sagan is an absolute legend and a hero, and his book Contact and the movie it's based on is phenomenal. HOWEVER... we examined the central conceit of the story - that aliens pick up our radio signals and return a message with instructions to build a machine - and look at the stars inside the 100 light-year bubble around Earth where our radio waves have traveled. And the potential of this happening... Well, it isn't good. Sorry Carl. See Privacy Policy at https://art19.com/privacy and Califo...

Up to 70% of amputees claim to feel pain in their missing limbs, and we're still not completely sure why. Some of the theories range from nerve damage to crossed wires in the brain to a redrawing of the mind's map. And some new therapies involving simple mirror illusions and cutting edge technology are helping amputees live less painful lives. And it's also making us question the very nature of reality.

Over the following days, as authorities reviewed his activity with security camera footage, they found that he went to great pains to dispose of his personal effects without anybody seeing. This was a man who wanted to disappear completely. And he was almost successful. But one random thing went ...
