The patented Gravity Energy technique is scalable and very cost effective. The current product prototype is 1 meter high and works with wind, waves (so could float on water) and gravity. It charges a battery for electronics and outdoor lighting. Larger set ups (still to be developed of 10m, 50m, ...) could charge subsequent larger devices. Smaller set ups could charge off grid sensors.

First user case in 2024 is the here shown demonstration lantern made by TU Delft and support of TimerLab outdoor solutions. Second user case in 2024 can be an energy post for charging electronic devices for Red Cross.
