Gravity Energy ^©

Gravity Energy develops a patented mechanical energy-harvesting technology for outdoor infrastructure, autonomous systems and other applications where environmental movement can provide supplementary energy.
Following years of development and research, the technology is advancing towards application-specific field pilots in collaboration with TU Delft.

Potential applications include:
Smart infrastructure, lighting columns and flagpoles,
remote sensors, cameras and wireless monitoring systems, marine and environmental monitoring,
agricultural monitoring and outdoor installations,
robotics and other moving systems.

Initial prototype tests have demonstrated electrical energy generation in the microwatt (µW) range. Further development and field pilots will investigate the potential to reach the milliwatt (mW) range and accumulate harvested energy for applications requiring higher power levels, potentially including watt-level charging over limited periods.

The technology is designed to complement existing power sources and batteries, potentially extending operating time or reducing battery replacement needs. Its practical value depends on the available movement, energy requirements and application.

Developing the next generation together:
Gravity Energy is looking for industrial and technology partners to explore specific applications through paid development and field pilots. Each pilot combines prototype integration, performance evaluation and testing under relevant conditions.
