How to Make HHO Fuel Cell Circuit in Automobiles for better Fuel Efficiency

Last Updated on May 16, 2026 by Swagatam 176 Comments

HHO2Bgas2Bin2Bmotorcycle

In this post we’ll try to investigate the making of HHO gas in automobiles for enhancing their mileage by approximately 50% or more, that means a reduction of petrol or diesel consumption by the same amount. In the previous post I tried to put forth an innovative design of a high voltage low current generator […]

How to Collect Electromagnetic Energy from Atmosphere

Last Updated on January 21, 2026 by Swagatam 132 Comments

freeenergycollectorcircuit 1

A free energy collector circuit helps to convert surrounding radio frequency waves to electric power and can provide 40 watts to 10 watts indefinitely. The Circuit Concept An option to increase the output power is achievable through proper set-up of an antenna. Placing an antenna in a close proximity of a large metal object helps […]

Making a Thermoelectric Generator (TEG) Circuit

Last Updated on January 21, 2026 by Swagatam 15 Comments

TEG

A thermoelectric generator (TEG) is a kind of “free energy device” which has the property of converting temperature into electricity. In this post I have explained a little about this concept and find out how we can use it to generate electricity from heat and cold. What’s TEG In one of my earlier articles I […]

How to Generate Cold Electricity

Last Updated on January 21, 2026 by Swagatam 35 Comments

cold1

Cold electricity is generated using an unconventional principle via the negative line of an LC network, which stimulates the flow of positive charge in the line, causing an entropic negative charge to develop across the inductor, which is eventually transferred into the capacitor as “cold” electricity. It’s termed as “cold” since it works within a […]

Charging Battery with Piezo Mat Circuit

Last Updated on January 21, 2026 by Swagatam 15 Comments

piezo

In this post I have explained a method to harvest free electricity from a  piezo embedded mat by walking on it, and try to investigate how this energy may be used for charging a small battery. Normally a human body carries a huge amount of energy which simply gets wasted in our regular day to […]
