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.
