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 generate additional power.

The wire of an antenna should be more than 150 feet long, which has to be placed horizontally on a higher platform to derive the best result.

The more the higher an antenna is set, the more it is able to act efficiently. However it is advisable to keep the circuit closer to an antenna.

The proposed free energy collector circuit on the other hand, also acts as a passive detector. As the large metal object passes wave, there is an increase in power. One major usage of this process is in the field of volcanic studies.

Selecting the Antenna

The sensitivity of an antenna is capable to detect variation of energy from earth and is often used to receive warning signal for a possible seismic activity.

So it can be summed up that the placement of an antenna is very much crucial for a better output. Also one can use many of these circuits to construct and connect their inputs together, to produce ample energy to run electricity in a house. However to note, each unit needs their own antenna to construct the same.

The Radio Frequency power varies based upon a location. If the set-up location is close to a city or in close proximity to the transmitters, which generates high level of Radio Frequency; leads to an optimal performance.

If you are excited to generate free power at your house from the atmosphere, then you can perform some experiment with different length and size of an antenna.

Altitude is Crucial

However keep in mind to place the antenna on a higher location for better result. During construction it is also necessary to keep in mind the earth ground of the circuit has to be properly conductive. The earth ground should also consist of metallic, conductive pipe or rod.

Improving the Free Energy Device

The following more comprehensive free energy deriving circuit design was forwarded to me by one of interested readers of this blog Mr.Prashanth Dhonde.

More info on the above design:

Using Fast Recovery Diodes

In order to generate more electricity, it is possible by stepping up with more diodes. To make it work properly, the type of diodes and the construction of antenna play a crucial role.

To begin with this process, let us first start setting up the antenna. In order to set an antenna properly, there are some key issues to consider.

An antenna should be made of Ferrite and a height of 30 inch rod is an ideal option to setup the antenna for receiving radio waves.

In regard to diodes, the Geranium the lowest loss diodes and a low breakdown junction voltage of ~ 0.2 - 0.4 Volts is ideal, in case you are unable to find the you may use the regular 1N4148, would just work.

A radio wave gets intercepted in areas with higher concentration and traffic congestion. In this kind of situation it is seen that each diode can pull around 30mV.

In the article: “In order to generate more electricity, it is possible by stepping up with more diodes.” An interesting article, but for anyone thinking they can get more power by using more diodes, that is wrong. The amount of power at the antenna is a value dictated by the antenna and the radio stations in the area. It is not related to how it is detected. By adding more diodes, what you are doing is increasing the output voltage using what are basically diode voltage doublers. However, every time you double the voltage, you halve the the output current current. So, it makes sense if you need a particular charging voltage but it will them tale longer to charge. Also, adding more diodes means there is an increased total voltage drop used up by the diodes so you won’t actually get exactly 2x voltage but slightly less and slightly less current as the diode effectively uses up the current. The more diodes, the greater the voltage, but the lower the current and the available output power.

Yes, the longer and higher the antenna the better as well as a good earth. This isn’t generating energy form the earth, but from the various transmitters in your area. If you live on an area with lots of powerful transmitters then you will generate more power. If you live in an area where you can hardly pick up any radio stations, you are out of luck. Also, as this is an untuned antenna, you will find the power varying through the day and even the year, depending on local conditions, in the same way as some stations become stronger at certan times of the day.

A long wire as high up as possible is the way to go as well as a really good earth. Other aerial designs are more efficient but that is because they are designed to work at certain frequencies. If you have a local radio station that you know is powerful and at a particular frequency, you could tune in to that specifically using either a simple crystal set circuit or a specially designed antenna, Is it worth the effort or cost? You decide!

A specially designed antenna would just be the length that corresponds to the radio station tuning frequency, correct? (Using the c constant formula for speed of light.)

Hello! Let me explain something to you. leave the circuit aside and take only the long wire antenna. This will capture electricity from electromagnetic waves of positive value and another wire that you will take from a grounding will give you negative electrical charges. Put a measuring device between them and you will see how many volts it gives you. For more volts, you will increase the length of the wire.

GREEN GREETINGS SWAG: Antenna power = pretty useless. An old fellow tenting in a city caravan park had 3 solar garden lights with switches; these he daily put in the sun for night lights.
For 33 years we have had only one ordinary 12 volt car battery so power has cost us nix over decades & battery does everything except power my 25year old homemade Prize dual trike with 1/4 hp motor that attracts no rego, license or insurance on highways, but not freeways in this country. All home large appliances are 12 volt (none 240 or 110 V) & largely homemade like: fridge (average power = 2.8 watts with 15cm foam all round, blender = small starter motor, TV, vacuum cleaner, coffee boiler, fans, pumps (some items worked off small solar panel without battery), insect zapper, many tools, laundry, bed warmer, computer & printer, brilliant LED lights, 2-way radios, sewing etc. Then there are many small devices either solar or preferably windup like: FM/SW radio, torches, shaver, calculators, stirrer, saw, brush cutter etc. The stove is my small 1979 smokeless single-stick invention that has air preheating & afterburning. But when in Cornwall UK – warmest county & only 10 minutes snow when visiting for 7 years – the all-glass veranda facing south heated the entire home for free to beyond summer temp for hours after sunset! Incidentally, the current to charge latest home mentioned car battery is provided by only a 46 watt PV solar panel + it charges the trike battery!!! If y’all want to know more I’m Dr.Pat Howden.

What if, as predicted imminently by great panels of US experts, that no: jobs, banks, markets, utilities, health, car, fuel, energy (California is reportedly verging thus), water, partner, security or happiness…? Disaster Survival is highly correlated with home multi-tasked self-sufficiency level as many experts agree, & we have been – including emission-free & total solar + edible jungle + solar dual vehicle (trike) – for 1/3rd century! Not long ago our Centerlink (dole, employment, pension…) + Tax office + Army + Medicare were on strike – intending to be at length.

I simulated the circuit described and make it available here tinyurl.com/y6wcb2b5 . It might look different, but electronically it is exactly the same. One can experiment with different load resistors. It is quite simple a negative and positive voltage multiplayer.
Additional Notes.
1. If you know the altitude of your antenna above ground, you can guesstimate the atmospheric potential at that altitude with the formula given so that you can determine safe and appropriate voltage ratings for your capacitors as well as be aware of handling while they are charged. Make sure to double that to consider days in which the atmosphere is more charged. Do not underestimate the importance of safety when handling capacitors, charged or not. The capacitors described don’t store much energy so they are generally safe but people are likely to modify the circuit potentially making it very dangerous to handle. It is well known there is an electrical potential between ground and the altitude above of an antenna or charge collector. On the other hand, what this circuit does is harnesses stray electromagnetic fields, and RF noise. Yes it is wireless transmission of energy, but it is not atmospheric energy.

the output could be too trivial to notice….perhaps many such circuits needs to be connected in parallel to achieve anything that might be worth considering..

Sir 0.22uf capacitor is not available in my city can you suggest me equivalent. And if i connect a 20ma led with one circuit then does it glow or burn out.

My home is on 2nd floor then the antenna is necessary or not..i means that i will use a shorter anntena or iron rod

Hi Syed, I have not yet tried this practically so cannot say about the results, but an LED will not burn I think, because the setup may not be capable of generating that much power.

0.22uF is not acritical value, you can any other capacitor with nearby values.

antenna is a must and needs to be included no matter on which floor you are, without antenna the circuit may not produce the intended outputs

Syed for this you may have to employ huge caapcitor may be upto 10000uF, it will also depend on the discharge rate (mamps) of your application.

Hi sarib, the output will be DC since it would be from the capacitor's stored energy which is always DC

I have completed the circuit and it works great, but in the bottom picture there are 50 circuits. Any idea if they are connected in series or in parallel? I have tried series to increase the voltage and it keeps decreasing rather than increasing. Any idea how you can hook this circuit up in series?

September 20, 2014 • 12 years ago #25825

That's great and interetsing, because most people have a skeptical view about such concepts,

in the bottom image the configurations are in parallel in order to increase current gain and the overall power of the output….it could be done in parallel first and then those parallel strings could be further put in series for getting a sustained boosted voltage

Dear Emmanuel,

A split charger would be preferable, you can build the following design, it is supposed to charge the batteries in a split manner by selecting the battery according to their charge levels:

Dear

another little confusion is the kind of charger circuit I will need in
charging the dual configuration setup of the batteries, because each of
the batteries am going to use have a high "AH" 12v 100AH and 12v 120AH.
Meaning do I use a single charger or a split charger type.thanks you

Dear Emmanual,

If you have a low battery indicator in your existing inverter then you could probably try the following design:

you can try any 4047 based inverter design, and add a 0.22uF/400V capacitor at the output of the inverter….. this will fulfill your requirement reasonably.

thank you Eng, Swagatam, but the reason why i need this solution is because the battery turns to burn the components and the jumpers on the circuit board.
Here is the link to the circuit i built.. https://drive.google.com/file/d/0B15SzCeSV14XekxNMEV6dl9YY2c/edit?usp=sharing

the image is not opening,

anyway, check the condition without any load…. if still it starts burning would indicate a malfunction in the unit.

unless the voltage is increased AH will not cause any harm to the inverter.

August 12, 2014 • 12 years ago #24969

mawuli, if your inverter is rated to work with a 12V supply you can comfortably use the 12V/60AH or any higher AH battery without worrying…unless the voltage is increased AH will not cause any harm to the inverter.

One of the best circuits ever seen. If I use any voltage booster IC(output adjustable one) from National Semiconductor or Texas Instruments and configure it for lets say 6V then if the voltage at the input increases or decreases will I get 6V at the output? If the output changes will the current change or voltage will change. Can I use 1N4007 diodes instead of 4148, 1N4007 is used for rectiication but whats the main difference between the two.

Thanks! I don't think ICs will work here.
1N4007 cannot be used since they are not specified for high speed detection. 1N4148 react much faster compared to 1N4007.

On this design, frenergy.ca/wp-content/uploads/2013/05/pyramid-flux-capacitor.bmp

what should be the proper capacitor/diodes to use? or any suggestions for this.

Hi Raymund,

The blue cap is 0.0002uF/5000V
The electrolytic cap looks like a 22uF/100V
The diodes could be 1N4148 or BAT30

Use LM196 for the IC if the requirement is upto 10amps.
