Energy Savings via Mineral Piezoelectric Technology
ECOMO is designed to reduce power loss at the source — your transformer.
Electricity loses energy at every conversion and transmission point — as heat, resistance, and electrical noise. This loss happens inside the flow of electricity itself, so even facilities that have already invested in efficiency upgrades still carry it, invisibly, on every bill.
ECOMO is a patented power-improvement device (patented in Japan, 2018) installed directly on the secondary side of a power transformer. Inside its sealed casing, a nano-powdered compound of tourmaline and ferrite are arranged to respond to the electrical noise and micro-vibration present in live transformer operation. Tourmaline — sometimes called the “electric stone” — is known for its piezoelectric properties, while ferrite is widely used in noise-suppression and EMI-filtering applications. Together, the compound is engineered to help stabilise current flow and dampen the electrical noise that would otherwise be dissipated as wasted energy.
Engineered to reduce electricity lost in transmission — so more of what you pay for reaches your equipment.

How It Works
A passive mineral-and-ferrite compound, activated by your existing current, that helps stabilise flow and reduce electrical noise — without touching voltage, frequency, or equipment operation.
The Material Science behind the scenes
ECOMO contains no electronics. Its effect comes from a compound of saline water and mineral nanopowder — principally tourmaline and iron oxide — held between an electrode plate and a magnet inside a sealed double shell.
Tourmaline
Known as “Electric Stone” since the 18th century, tourmaline is the only mineral known to naturally generate electricity under pressure or heat, producing a small charge (~0.06mA). It continues generating that charge indefinitely, even when crushed, unless heated to ~1000°C.
Ferrite
Known for its electrical noise-suppression properties, ferrite is a magnetic material made primarily from iron oxide, sintered with elements like cobalt, nickel, and manganese. It’s the same class of material used in magnets, making it effective for stabilising current flow.
