To create electricity for our modern AIDS - GPS, EPIRB, AIS, Satnav and so forth - we have four solar panels, a wind generator and a foot pump, which will also serve as exercise equipment.

To pump energy back into the grid, some of the rotational energy is bled off to power a generator on the main shaft.

The AOI Signal Converter measures rotary table RPM and pump SPM without the use of a generator.
