Is this Inductive Overunity? Maybe Not

Last Updated on May 20, 2026 by Swagatam

free energy

While experimenting with a 300V DC to 220V AC inverter circuit, I noticed a strange overunity phenomenon which appeared to be like the generation of free energy from the inverter transformer. Recently while experimenting with a high voltage converter circuit, I was quite astonished to see a strange overunity kind of occurrence wherein the inverter […]

Generate Electricity from Regenerative Braking System for Vehicles

Last Updated on May 20, 2026 by Swagatam 3 Comments

freewheel 2

Whenever brakes are applied in any vehicle, a lot of energy is wasted in the process of stopping the vehicle mass and again restoring the mass back to its original speed. The simple idea designed by me appears to be quite effective in solving this issue. I have explained more about this simple regenerative braking […]
