Natural airflow through the pillar and housing cools LEDs, the solar panel, and battery while reducing contamination in solar street lights.
Oscillating magnets in rotating cylinders pass through coils to generate electricity from wind or water with more continuous output.
An external supply powers the main line and recharges internal backup storage, reducing generator size and offshore backup complexity.
A battery-backed dead zone lets storage absorb small frequency swings, reducing turbine control wear while maintaining fast grid support.
Accelerated vehicle airflow in a Venturi drives piezoelectric flag sheets to harvest onboard electricity and help extend EV range.
A cylindrical fan generator recharges EV 12-Volt circuits in motion, reducing main battery drain and extending driving range.
