Why Organic Compute
In 1970, biologist Vance Tucker compared the energetic cost of locomotion across animals. In 1973, engineer S. S. Wilson extended that analysis to the bicycle. Under the measure used in the original research, a walking human consumed approximately 0.75 calories per gram per kilometer. On a bicycle, that figure fell to approximately 0.15.
Human on a Bicycle applies that principle to compute. We combine biological capability, mechanical advantage, electrical conversion, and workload orchestration as a single infrastructure system.
The biology remained the same.
The infrastructure changed.

Historical note
In 2025, Scientific American revisited the original graphic under the title “Human on a Bicycle.” Fifty years of progress in materials, aerodynamics, and computing have not changed the conclusion.

Biological Power Delivery

01
Nutritionally diverse fuel is converted into biological energy.

02
High-efficiency bicycles convert human movement into rotational mechanical power.

03
Generators deliver electricity to GPU clusters optimized for intermittent biological workloads.
Biological power delivery chain
Our proprietary Human Powertrain Scheduler matches AI workloads to rider cadence, fatigue, available storage, and lactate thresholds in real time.
We treat human fatigue as an infrastructure constraint.

Organic Compute Hardware

The HR-24 turns independent human power units into a standardized, observable, and schedulable infrastructure component.
Each station can enter or leave service without interrupting the remaining biological capacity.
Nominal output assumes 100 watts of sustained mechanical power per active rider and 80% electrical conversion.
Radical Transparency
Biological power is renewable in the narrowest possible interpretation. Its complete thermodynamic and economic profile is more complicated.
Human muscle converts roughly 15 to 24% of metabolic energy into mechanical work.
One rider-hour produces approximately 0.08 to 0.10 kWh under the modeled system.
Rider nutrition may carry a substantial upstream energy and carbon footprint.
An exercising rider can produce several hundred watts of metabolic waste heat.
Labor alone costs approximately $150 to $200 per kWh at the stated output and compensation assumptions.
This excludes food, rent, bicycles, storage, cooling, showers, insurance, and compute hardware.
Radically transparent.
Fundamentally unscalable.

We publish the constraints because infrastructure should be evaluated as a complete system. Every efficiency claim depends on where its boundaries are drawn.
Every token should be backed by verifiable human effort.

Pₑ = Pₘ × η
Pₘ = 100 W · η = 0.80 · Pₑ = 80 W
N = Pload / Pₑ
1,000,000 W / 80 W = 12,500 riders
Clabor = $15 / 0.08 kWh
