Score any machine
on its physics, not its hype.
The Guarino Similarity Metric collapses thermal, electromagnetic, structural and aerodynamic performance into one dimensionless score — so a turbojet, a Formula-1 car, and a deep-space ion thruster sit on the same leaderboard.

How it works
Step 1
Pick a machine
Browse the catalog or scan a photo. Every entry is tagged with its physical regime — automotive, aerospace, robotics, marine, and more.
Step 2
Read the G score
One dimensionless number summarising how much useful output a machine produces per unit of penalty (weight, friction, heat loss, drag).
Step 3
Compare or improve
Stack two machines head-to-head, or get AI-suggested upgrades with concrete parts and price ranges.

Six ways in
Scan
Take a photo or describe a machine. AI identifies it and estimates its physics score.
Analyze
Pick any machine in the catalog and inspect every Π-group with plain-English labels.
Compare
Head-to-head match-up with an AI-written technical breakdown of why one wins.
Improve
Pick a machine, get AI-suggested upgrades and a projected new score.
Ranks
Leaderboard of every machine, filterable by regime — automotive, marine, deep-space.
