Tension-based mobility treats momentum as a shared resource rather than a private expense. In conventional transportation, energy is burned in isolated vehicles, most of it wasted as heat and friction. In a swing network, energy is stored, transferred, and reused. Your movement helps the next traveler. The system’s efficiency grows with participation.
Imagine your morning commute starting with a pendulum drop. You build speed on the descent, and that speed is not just yours. At transfer nodes, mechanical systems capture a small portion of kinetic energy to assist uphill arcs or heavier loads later. The network’s energy balance becomes a public good, similar to a shared water reservoir.
Mechanical Advantage Instead of Fuel The core mechanism is simple: gravity accelerates you, and your body controls trajectory. The most energy-intensive part—climbing—is handled by stored momentum or small assists. Instead of large motors, the system uses small, distributed amplifiers that harvest energy from the motion itself, solar panels on support structures, or wind-driven tension adjustments.
Distributed Gains Because each traveler adds to the system’s stored energy, the network improves under load rather than degrading. High ridership can actually increase efficiency at nodes, just as busy markets generate more social energy. This flips the economic logic of congestion. Where roads slow under volume, swing networks can smooth and self-balance.
Economic Effects A momentum economy changes what cities pay for. Less asphalt. Less fuel. Fewer large vehicles. Lower maintenance. The savings are not only monetary but spatial. Land once used for parking becomes homes, gardens, and public space. This reallocation has cascading effects: local commerce thrives, health costs decline, and communities reinvest in their own infrastructure.
Design Implications Designing for momentum means prioritizing arcs, gradients, and continuity. Routes are chosen not just for shortest distance but for energy logic: where downhill energy can serve uphill demand, where natural topography can provide acceleration, where node placement can smooth transfer. The city becomes a map of energy flows rather than traffic flows.
Cultural Shift When movement produces value rather than cost, social behavior shifts. People choose routes that feel good rather than routes that minimize time. Movement becomes part of daily well-being. The economy of motion becomes a shared civic resource, strengthening social cohesion around something everyone uses.
