Prufrock-3 testing has kicked off in Bastrop! Targeting full continuous mining (ie machine never stops) and sub-24-hour surface launch.

Note that the Mining Director is calling out main drive motor rpm, and there is an approx 500:1 gear ratio between motor and cutterhead rpm.

Here’s a look at the Boring Company facility from the air recently!

But will it beat Gary? 🐌

Is 600rpm the top rotational speed?

3200 rpm for the motors (6.4 rpm for the cutterhead)

Thanks for the reply. I’m so excited about all the work you all are doing.

You can’t get more subterranean than that! That is a man-toy on steroids *Tim Allen grunts*

@nyerek001 How it is propelled to move forward. Can't imagine it....

This is going to put a stop on wasteful subway construction. 🎉

Why has no one tried to significantly upgrade the violence of these cutting heads? This thing is just scraping under pressure, why are there no hammer elements that pulverize the rock faster? Like really powerful electrically (linear motor) driven hammers that actuate at 50hz with 10inches cm of travel.

looks slowly but powerful

This is huge! How does Prufrock3 do continuous tunneling?

Epic digger!

that is so cool

My brain is trying to comprehend how this is even feasible. Technology is so cool

I ❤️ The Boring Company

So about a million times faster than what's happening at Snowy 2.0.

Let’s start digging !!!!

Colonize Earth!

The Boring Company inspires to battle shorter lead times and high visibility.

What’s the distance?

Break a rock

Is it faster then Gary the Snail?!?

That’s not even 2 RPM. 🤷🏻‍♂️

Are any of these eventually going to go into the rocket and be deposited on an asteroid or Mars? Seems like they could fit.

Is material removal from the site still a limiting factor? Would love to hear more on that progress as well as innovations in casing the tunnels.

"-3" is a serial number, or a version number?

One hell of a drill bit

Hate to be the one to have to clean that..

Get in there

looks more like 1 rpm not 100. the motor maybe running at 100 rpm and there is a gear reduction ration of 1:100

How long does it take to manufacturer one? Would be nice to have a fleet? ...swarm? ...labour?

@BoringPrufrock Tell me more!

woah thats...fuckin AWESOME! had no idea what you guys were working on as info on boring company is few and far between, would LOVE more updates

How much more time efficient could a nuclear tunnel boring machine be?
