The world isalready built.Now it must change.

A new way to cut rock and concrete. From one side.

The problem

We asked the people on site:where does it hurt?

Hydropower

“We keep cutting too close to cables and pipes.”
Hydropower owner

Tunnels & bridges

“Wire sawing is fast, but it puts the crew at risk.”
Road contractor

Buildings

“You can't touch the beams and walls next to it.”
Large contractor

Three places. One problem.

Inside a power station, one unit standing still for a day costs about NOK 1.8 million.

Paraphrased from our interviews with owners and contractors.

What we built

One block out.The rest stays standing.

A small blade on an arm, instead of a large bladeComparison of a two metre or larger conventional blade and our 23 centimetre blade on an arm reaching 1.1 metres deep. Schematic, not to scale.2 m+ · BLADE OTHERS NEED23 cm · OUR BLADE,ON AN ARM1.1 m DEEP

How it works

The arm sets the depth,not the blade.

  1. 01

    A rail goes on the wall.

  2. 02

    A small diamond blade cuts in.

  3. 03

    The arm carries it deeper, pass by pass.

  4. 04

    The pump stays outside, out of the way.

Everything around it

Safer for the crew.Gentler on the structure.

The crew

  • Dust bound in water
  • Out of the risk zone
  • No one holding a hose

The structure

  • No blasting. No hammering.
  • Clean corners. No overcuts.
  • Carried in. Mounted on site.

The field test

Cutting at Evangerthis December.

Where
Evanger power station, 330 MW. It keeps running while we cut. That is the whole point.
With
Eviny and Mesta. The owner and the contractor. Both on site, watching every cut.
What
Real cuts in concrete, inside a running plant. Not a lab.
DEPTH
how deep, in real concrete

Measured on site, December 2026

SPEED
how much we cut in a day

BLADE LIFE

The team

One physicist with an idea.Now five.

How it started

  1. Rock blocked his garage.
  2. In Minecraft, one block comes out.
  3. Nothing else moves.
  4. So he tried it for real. It cut.
