Hey guys, I'm the Hacksmith and on this episode Make It Real
We're gonna try and make a real arc reactor since it's been one of your most common requests
So what exactly is an arc reactor
Well, it was first introduced to the MCU in Iron Man, and just looking at it
It looks like it produces a continual arc of electricity in a loop and somehow that generates power
Infinite power
To me. It kind of looks like a perpetual energy device
which we know is impossible because the most fundamental law of physics is the conservation of energy
Which states that energy in a closed system is constant, which means energy cannot be created, only transformed
That simplifies into an equation energy in equals energy out plus losses
Usually in the form of heat because of the second law of thermodynamics
We know there are always losses
always
Which kind of makes sense when Obadiah says this
The arc reactor. That's a publicity stunt
We built that thing to shut the hippies up
It works
Yeah as a science project
But then in the cave when Tony miniaturized the arc reactor he uses palladium
What is that?
That's palladium 0.15 grams?
Which suggests the arc reactor might actually be nuclear technology since some palladium is radioactive
Unfortunately, it's also highly carcinogenic and toxic so I'm not about to play with palladium for a fictional technology
Now the power output specified is also kind of ridiculous
What could it generate?
If my math is right? And it always is.
Three gigajoules per second.
Joule per second is just a fancy scientific way of saying a single watt, which means the arc reactor produces three gigawatts of power
That's almost three times the power output of a time-travelling DeLorean from Back to the Future
1.21 Jigawatts!
In fact
If we were to sell that energy back to the power grid the same way I sell solar energy from my roof
it would be the equivalent of
833 kilowatt hours, which would generate 250 dollars per second of income or 21.6 million dollars per day
basically, if I were to invent a real working arc reactor
all of our funding issues would be solved and we'd be well on our way to building a real life Iron Man suit or
More realistically our entire company would be assassinated by the big oil companies
So it's pretty much impossible to make a real working arc reactor. So let's build a real working arc reactor
All right
Now before we build the arc reactor, let's take a look at a 3D model using some augmented reality tech, not unlike Tony Stark himself
Pretty cool, right. Let's take a closer look
Now it looks like the electricity is being generated in the final ring of the assembly
But I guess the real question is if we're building an arc reactor. How are we gonna do that?
Let's get some paper out and actually do some calculations by hand
So to sustain an arc of electricity around the arc reactor we're gonna need a lot of voltage
The diameter of the arc reactor is around 75 millimeters across which gives us a circumference of around 241 millimeters
Which would be the path the electricity actually has to follow now
It takes approximately three million volts to ionize air for an arc to form across a distance of 1 meter
That's roughly 30,000 volts per centimeter. So with the 24.1 centimeter travel path, we'll need approximately
723,900 volts of electricity
Luckily, we have these little high voltage transformers which produce about 80,000 volts each
There's 10 segments in the arc reactor. So that would be about 800,000 volts
This might actually work. Let's start assembling it
They do need to be close together so I might thicken up that divider wall.
Yeah, that'd be good
Smells nice.
Yeah, I don't know what that is, I think it might be acrylic but
Most realistic arc reactor ever
Yeah, so these wires
They're not very thick, but like if they're next to each other they don't arc
As long as there's something else there. So I'm wondering how thick the wires I need carrying the high voltage near my body
See, perfectly safe
As long as you don't become the path of least resistance, you'll be fine
All right, now that we have most of the components assembled we're gonna have to control them somehow
I made a quick block diagram to explain how the circuits actually going to work
But basically we're gonna use a relay bank to control the outputs of each high voltage module
Using an arduino. The power input is from a lithium polymer battery
Now we actually have a more detailed
electronics diagram which you can check out using the link in the description below to visit our project on maker.io
The battery is connected to all those
This powers the arduino
Ready for its first test
The most realistic thing about this arc reactor is the number of wires coming off of it because if it was actually producing that much electricity
You'd need some serious
Current carriers to get that energy some are useful
All right
so we've got the arc reactor all set up and we have a clamp meter to measure the current flowing through the wires
As we do a start-up sequence
20 amps!
All right, so obviously I don't have a hole in my chest so I can't actually wear this arc reactor
So I thought it'd be nice to make a nice kind of like display case that we can use
For when we're actually powering stuff using the arc reactor
All right, so we've got the arc reactor in its box now and we've actually got the switches on the box
So let's open it up
All right, so main power is this switch here and we'll try and do a startup sequence
Alright let's see if it can power a phone
All right, let's see what else this can power
All right, so we're here at the main circuit breaker for my house and we're gonna plug in the arc reactor
All right, let's turn it on and see what happens
All right, so these are the power meters for the house and as you can see that's how many kilowatt hours we're using
All right, let's reconnect it to the grid
All right, so obviously it's not actually producing enough power to do anything useful
But it certainly looks cool and sounds terrifying
We'll be using it for some future gags in upcoming videos where we use it to actually power our projects
One of our goals here is to inspire people into STEM fields to learn and create things themselves
We get tons of messages asking how we learn to do this stuff and the answer is simple. I'm a problem solver
I'm not some kind of genius. I just like to learn and use those concepts to make cool stuff
I learned by doing and that's exactly what brilliant.org allows you to do
Brilliant.org is a problem-solving site that helps you think like an engineer by guiding you through the problems that bring you from knowing nothing
To having a deep understanding of the topic
