- [Destin] Oh dear me.
- [Jeremy] I'll let you know!
(machine whirring)
- Ready?
Oh my goodness.

(Smarter Every Day Intro music)
The major league baseball home run distance record
is around 575 to 580 something feet,
depending on where you get your data.
Today on "Smarter Every Day",
we're gonna try to beat that with engineering.
We know that major leaguers swing the bat
at about 90 miles an hour,
and so you get this exit velocity that's really high.
I don't know what it is, 100 something miles per hour.
We have devised an apparatus,
my buddy Jeremy Fielding's
been working on it for months now.
We got a three phase generator hooked up to a huge motor
and a pulley system that gives us the right gear reduction
so that we can spin this bat at crazy velocities.
We're on this little league baseball field
that I played on when I was a kid.
We're gonna try to crank some homers at over 600 feet
and see if we can beat the home run distance record,
hopefully even put one back in those cows.
Alright, I'm Destin.
Let's go get smarter every day.
First thing was to get everything off the truck
and to get it over to the batter's box
and begin to line it up
and take into account where the sun is
so that we can get the right slow motion footage
and what angle we wanted to set the bat to.
Oh yeah, it's about to get crazy.
I'd like to stop and acknowledge
the ongoing launch angle discussion.
This is an entire field of study
having to do with the exact angle of attack
that you need to swing the bat at
in order to impact the ball at just the right position
and get the right exit velocity
in order to put these balls over the fence.
This is an entire thing.
Unfortunately, the reality for us at this moment
is that we're just trying to point at the fence
and swing a bat as fast as we can.
Where are we gonna be, dude?
(Jeremy) - I don't know,
but I want to be outside the fence, wherever else.
- If the ball comes off the bat like we expect,
then death will be imminent for the pitcher, which is me.
Hopefully this will stop any splintered bat
and or 200 mile an hour baseball.
We'll see.
Alright, here we go.
80 miles an hour, let's see if we can hit the bat.
(baseball whizzing by and hitting the backstop)
So the problem with this whole set up
is we have no active feedback
because the batter can move the bat as he swings, we can't
so we're just gonna throw it a ton of times
and hope that we get one that just lines up just perfect
because then it's sailing.
That's it, money shot, let's do it.
What just happened?
Okay, low speed swing test.
Good.
- Yes, that's about as high as I want to go
if we're standing here.
- That, but 200 miles an hour, that's next.
The problem is, Jeremy realized
we weren't getting full power
from the industrial generator we rented to run this thing.
Now is probably a really good time
to explain to you who Jeremy Fielding is.
Jeremy Fielding and I became friends at ThinkerCon
where we realized we were both dads
who loved to build things.
Jeremy has his own YouTube channel about mechanical design
and he's really good with electric motors,
so it's super fun to learn about this stuff from him,
especially when he's trouble shooting the equipment.
- We've only got 30 volts between lines one and three.
- So one of your legs is out? - [Jeremy] Yep.
