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 […]

Portable Power Generator Circuit – The N-Machine

Last Updated on May 20, 2026 by Swagatam 46 Comments

n2Bmach 1

When this free energy generator called the N-Machine was developed by the famous physicist Bruce DePalma he could implement a 100 kilowatt generator right in his garage with ordinary tools. His machine could power his entire house electrical completely free of cost, forever. But sadly he could never use it since making such device or […]
