HI Team

I arrived at this forum with the goal of learning how to make a Eternal Flashlight, but found a wealth of knowledge far beyond expectation. After much reading, watching, coils and experimenting quietly, its is now time to see if I can offer something to this effort. 

I decided to start with a "Lariman" build due to its circuit simplicity but still with the necessary components to understand the coils and what is required to tune them to the circuit. I have ordered circuit boards based on the above design and have a number of spare which I am happy to post to any one willing to commit to building and posting their progress.

Lariman Circuit Boards

So I will build one up and wind some coils and post progress soon.

Hi,

Anyone catch the Pot Core number?

I have been a troubleshooter around electronics enough to know to question everything.....what if the L1/L2 coils were reversed......the same approximate length of wire (23 arms, and 26 arms) for each being about the same.....the inner core would result in more turns than the outer core which would result in more inductance......I need to do some math.

Hey Brian,

If I were you, I would put this particular experiment aside for a little while, but concentrate on the effect!

I have shown the very same effect here: Non-Inductive Coil Experiment

The Effect is where you will learn the most. The Effect is Asymmetrical Regauging

Best Wishes,

Thanks Chris

Are you able to be a little more specific when you say

 we have to tune the coils to the Circuit, and not the Circuit to the Coils, its a fiddly task!

I am not sure if I should be 

  1. Adding or removing turns on primary or secondary
  2. Adjusting copper strips to adjust capacitance
  3. Changing the timing cap
  4. Something else I may have overlooked.

I have been going around in circles with this for some time now not really sure with what to tune to get the result?

Hi Team

Been a while since I updated this post. Thanks to some encouragement by Chris I thought I would pull this project out and take another look at it. Looking back through this post I see it has been about a year. Wow how time gets away.

I was paying a bit more attention this time to the tuning with the 20K pot and noticed that it may be worth using a 10 turn pot here it seemed to be easy to skip past some sweet spots. Seems my scope is getting interference between the channels. Might be time for a better one?

 

I tried further tuning via the timing cap on pin3 of the MC34063, but the effects were minimal.

I welcome suggestions for directions to make this self run.

Many Thanks

Brian

Hi Brian
It's a great and rewarding experience.
To avoid burning other LEDs you can add a load resistor in series with your LEDs, this will limit the current flowing through the LEDs. Here a small calculator:

Hi Team

I have been experimenting with a simplified design using the coils to switch the BJT and combined this with POC coils.

My idea was to have a "semi" self tuning pulse similar to Jagau's SRO and a very basic implementation of Melnichenko circuit above.

Here is what I have started with, very simple, but some very interesting results. Will run on as little as 0.5volts while still lighting 18 LEDs. 

In the picture below the Blue trace is accross the BJT and the Yellow the current through a 1ohm resistor on the CCW coil. Nice sawtooth wave. 

As you can see I am using 1Volt supply which is drawing 70mA and lighting brightly 18 LEDs. Surprisingly the circuit draw with only 2 LEDs is still about the same.

The variable resistor is a 10 turn to allow for fine tuning. Surprisingly it adjusts for a very wide frequency and influences voltage peak and current draw as you would expect. 

I have much to explore yet as I have burnt out several BJTs, VRs and over 20 LEDs as I tune to a frequency slightly below where I am at here. As I approach this point the cores vibrate loudly and there is ringing pattern across the BJT then puff. I solved this by limiting the supply current, but have some investigating to do here.

Raising the supply voltage increases the frequency and the current in the system. Which extends the sawtooth wave approaching more the ideal.

There are many areas to explore here. 

I encourage others to give this very simple build a go.

Kind Regards

Brian

To answer your question honestly, I haven't seen any real replication anywhere on the planet.

The only replication that comes close is the eternal blinker you did, that's a good start.

To return to the circuit that Akula proposes, the subtle difference that you have surely noticed is that it does not use any capacitor in its oscillator, only the capacitive effect between two coils, we have reached the same point in our research Brian, he only remains this effect which has not yet been found.

Hey Jagau

Using your standard SRO design connected to L2 and taking .2uf steps from .2uf to 2.2uf the result is bursts of oscillation of the frequency 300 to 390kHz with L3 loaded and up to 1MHz with L3 open

The SRO circuit does not maintain a constant oscillation. But with 3V supply the bursts are 18V so could charge sufficiently the C1 cap in Akula circuit 

To your knowledge has there been a replication of the Akula 1W Lantern circuit?

It has a beautiful simplicity, but I cannot make out from the video the detail to replicate.

Hey Guys,

Pardon my interruption, do you guys mean: Silicon Rich Oxide (SRO) Capacitor?

I think instead of assuming and taking a chance on meaning, I should ask and be proactive in the pursuit of understanding. 😏

Hi Brian
Instead of 200pf on the SRO, try

between 1 and 2 microfarad you should have a good oscillation, as you have very low inductance

Jagau

Jagau posted this 09 May 2022

Ok I see
You make it exactly like Akula's schematic.
In other words this one in real.

As you can see it is not as simple as in its schematic and more if you count the number of transistors there are 4 and a greater number of conductors output. We don't know yet if it's an air core or if internal are orthogonal winding.
I will review your request and get back to you with suggestions.

Hi Jagau

Details of the my circuit.

L1 4 turns - 8uH, L2 98 turns - 13uH, L3 98 turns - 19 uH,

T1 TIP41 (akula video shows a transistor in a TO-3 case)

T2 & T3 - 2N3906

D1 & D2 - 1N4004

What are your recommendations Jagau?

Jagau posted this 08 May 2022

 

Hi Brian

For this I would need the number of turns, of each coil and their iductance?

Very low inductance mean megahertz range of operation.
Normally with the intrinsic capacitance of each coil this is enough with the SRO

but for some we must place a capacitor in them

Jagau

Brian posted this 08 May 2022

Thanks Jagau

I did go back to that experiment several weeks back. I felt that stated 3v 10ma start supply was not enough to produce the trigger on L3 to begin oscillation, so I upped the voltage and played with R1 value but couldn't get a significant pulse. Maybe L3 needs more turns.

I would be very interested if you have a working circuit for this. I really do like the coil design.

Hi Brian

To stay in the interesting subject of your thread Brian, when you built this coil similar to that of Akula

  I think you had some problems with the start of the oscillator.
Therefore, a more in-depth study of the circuit is necessary. The last circuit you built on the collection of radiation around us is a good basis for understanding what will follow and you will notice that the circuits are similar in their operation.
If I bring this circuit comparison:

scr de bjt


 
As much as the circuit of Akula in comparison to that of the SCR with 2 BJT it is easy to understand how the gate of the SCR is triggered, see the yellow line on the two circuit comparisons is the one that interests us so with a negative pulse the scr is active. Before continuing I stop it for the moment so that the two circuits can be digested and understood and even experienced.

Hi Brian
yes Melnicehnko's experience is far from over, I have other things still developed that I will publish soon.
For the eternal blinker here it is:
The circuit presented here is a replica of the Akula lamp but with a single LED that flashes eternally, harvesting the energy that surrounds us.
It is based on the principle of Akula's first circuit:

2


 
You will recognize the SCR in 2 BJTs, namely T1 and T3 as well as a trigger T2 which recharges the capacitor C1.
I built this circuit with a modification of the T2 trigger circuit which flashes an LED by harvesting the energy around us. The more energy there is around you, the faster the LED will flash.
The circuit :

mon ckt

There's no battery, only a capacitor that charges as you harvest ambient energy. There are two grounds in this circuit, one on bare copper with a ground rod outside planted in the ground and another ground which can be either your body or the metal of your work lamp as in the following short video. I built two, one on bredboard and one on a fixed plate.

This circuit has been in operation since November 2021

Have fun

Hi Jagau

I am certainly interested to take up your offer to make the eternal flasher.

I have many projects on the go that are almost there and or demonstrate the effect needed, it would be great to finally achieve a small self running success.

I only just managed to recover from a old UPS a suitably sized transformer to use its core for your Melnichenko's Effect experiment. as well as waiting for IGBT delivery.

I do apologize for not updating progress on this eternal flashlight experiment, the reason being I have not been able to advance the knowledge for success as yet. Many have commented on the fickle nature of this design and felt that working with his later designs that can deliver a more practical power level would both help advance my understanding and be more productive in terms of out come.

I look forward to the construction details of your eternal flasher.

Hello Brian
I don't know if it's going well for you, give us some news about your experiences.

I would like if you have the time to make an etlernal flasher ?

. I have one here that has been working since last year, with only one LED though, and recharges itself with the energy that surrounds us and does not need to be charged at the start and works without batteries.

My Friends,

I have used a BUZ11 Mosfet and that worked fine as did the 3055, but trial and error with Coils and the Circuit made specifically for predesigned Coils is not what we have done here, we are attempting to guess the Coils Design around the Circuit, not an ideal option as this is much more work!

Experiments here on this website, aboveunity.com, sheds more light on what is supposed to occur here.

Brian, you had the effects in the Coils, you just need to focus on those effects and see what is actually occurring there, and work out how to improve this effect, after all, this is Asymmetrical Electromagnetic Induction.

More work on this effect will yield results!

Best Wishes,

Hi Brian


IRF840 and 3205 both have a min of 2v and a max of 4 volts for Vgs and that's normal.
To find an even match you will need to use other 840s that match your original 3205

Jagau

Brian posted this 06 April 2022

Hi team

I have spent some time working with the different FETs. The following are my observations.

Using the IRF3205 the circuit works happily on a supply of 2V, But if I substitute the IRF840 the supply needs to be increased to 4V to get it to switch. This is a little confusing as the specs of both indicate a min threshold voltage of 2V - am I looking at the wrong specification here?

The knock on effect is the different supply voltage then induces a different frequency of operation for the coils / circuit interaction.

So then I explored that maybe I needed a higher supply to hit the required resonance? The first point of note is with the use of either FET as I increase the supply (up to a max of 9V which is the design) the current draw increases till a point where I burnt out the LEDs. I had hoped it would co operate and self run before this point laughing

As Chris has pointed out many times it is Magnetic resonance that is required so we need to ensure the circuit operates in the region of this resonance. With this in mind I went back to measure the the coils I am using to see if this might provide some clues if I was in the correct range. The unloaded (open) measurements are:

L1 28.9mH, 158uF, 0.7ohm - which calculates a resonant frequency of 74.48Hz = this is within the range of what I am able to tune the circuit.

But this is where I need some direction to clarify my understanding. Firstly if we then connect L2 to the circuit as the load, the measured characteristics change (measure L1 with L2 in circuit, the resonant frequency result is 982Hz). Secondly it is my understanding the magnetic and calculated electric resonance do not necessarily appear at the same frequency and the interaction between coils and loads impacts this greatly. I have been attempting to confirm the point of magnetic resonance by scanning the input frequency to L1 with L2 loaded while measuring the current draw and response voltage, looking to minimize the current and maximize the voltage as a indication of the correct frequency to work towards.

I guess my simple question is - is there a process / procedure or calculation that is able to more closely identify the required design specifications to reach our goal? I feel that this may be the genius of Andrey, his knowledge and understanding is such that this answer is second nature.

I note also that working with various POC designs, many measurements and results are much clearer and predictable, than my experiences with this experiment. This is the Genius of Chris's POC work and guidance.

Anyway a quick update and more work to do.

Kind Regards

Brian

Hey ISLab

Really appreciate your suggestions. I admit I have been a bit lost on what to try next.

Yes I have tried a IRF840 early in the experiment, but it makes sense to revisit this now you have pointed out the rise time difference.

I confirm I am using a 1N5819 diode.

As you point out fine tuning for resonance is key and it would be so easy to miss it by adding or removing turns. Further experiments with the cap is a great idea. I have some variable air capacitors I will introduce into the circuit that should get the small increments we a looking for here.

I have not varied the copper strips at all, rather I tried to replicate proportions shown by Andrey.

My secondary is all one direction as this appears to be how it is wound in the unwinding video. Although he does drop the coil part way through which is a point where it could reverse direction. I need to take closer look at this.

My best performing coil is L1 4.7m 29mH 0.6mm copper and L2 9.85m 97mH 0.45mm copper.

I will set some time aside to work on these ideas and report back.

Many thanks for your help

Brian

Hi All! Unfortunately I've been held back from posting due to pressure of circumstances, but will resume as soon as I can.

Meanwhile I've been lurking off and on in my free time, and more recently went through this thread in detail and am very impressed with Brian's amazing work!

Dear Brian, your work is so good! You are sure to succeed!

Based on my limited experiments with my coils, I had a few suggestions on what you could tinker with:

  • check your MOSFET, and use one with short rise-time. I got a huge difference by using IRF840 instead of the IRF540 used by Swagatam circuit. If I understood right you are using IRF3205 which has a rise time of 100ns, whereas the IRF840 has a rise time of 23ns. Try it. Might make a significant difference in raising your induced voltages.
  • Are you using 1N5819 Schottky diode? It is shown in the Datasheet example from which this circuit is almost a perfect replica.
  • If I think about how Melnichenko would have tuned his devices, it could be that after winding coils of calculated lengths, he would have added or removed turns to get the best resonance. But also he might have had to fine-tune the frequency or capacitance. Did you get your 510pF capacitor for the setting the right frequency? Consider changing its values slightly up and down in increments of 1pF since these caps are rarely of exact value. Slight shift in this may be just what is required to get your coils to resonate now that you have them in right ratio.
  • Or you might try to fine tune coil capacitance by lengthening or shortening the copper strips. Notice that they are not covering the full perimeter, so perhaps he cut the outer strip to get optimum resonance. Or perhaps they need to be of same length? Or perhaps they need to be of same angular arc (but different lengths) to get the best capacitance effect?

Just some things I would try once I get to attempting this on my own, hopefully soon! Meanwhile I will have to limit myself to participating in your efforts vicariously.

Just out of curiosity, is your secondary still wound as POC with half as CW and other half as CCW? What is the number of turns and/or length in your optimum ratio?

Wishing you success!

Hi Team

Sorry I have not posted in a while. This is due to a number of reasons:

  • not making any progress with this eternal flashlight.
  • getting side tracked with another little project which was interesting but not worthy to take up time here.
  • but mainly it seems I do not yet have enough knowledge to know which way to go with the coils of the flashlight or possibly other parts of the circuit. As the small changes I made did not bring the fruit I am looking for.

So at this point I have been spending time following closely the excellent work of ISLab on his thread ISLab's Replication of Basic POC Effect and working to get a better understanding and feel for the actions in the coils.

I have some interesting results I will share shortly.

There are a multitude of circuits available on the forum. Maybe I can suggest this circuits that I built that work very well.
I do not know your ability to build such a circuit but you will tell me if it is too elaborate for your needs.

Thank you for your kind words of encouragement and direction Jagau and Chris.

I will study further your recommendations and post results.

I have also been experimenting with the POC's. I use various configurations to drive the input coil including straight from a signal generator (this has current limitations), Jagau's SRO (which works really well but has limited control for scanning frequencies) and my own simple FET circuits (which I wonder is there a better option). I note that this is probably not the best place for this info, but does anybody have a basic reliable drive circuit that can be connected to a controlled PSU and Signal Gen to drive the input coils?

My Friends,

Jagau is absolutely Correct! We never give up!

We have shown many times here on this Forum, that the smallest detail can lead to the biggest discovery!

I agree with Jagau, youre doing an excellent job Brian! We can see you have come very far in a very short time! Your Scope Shots Here, are absolutely spot on! Just remember, Voltage is "Generated", via Faradays Law, dΦB / dt, the Density of the Magnetic Field, from Min to Max, is where you need to focus in that Scope Shot, dont forget the Thread: Coil Geometry this will guide any readers in the General Direction of getting your Magnetic Fields Up, which is very important, Voltage depends on BMax.

Dont forget, focus on the Magnetic Fields Slapping together, this creates a Standing Wave of Current, and doing this "Generates" a Voltage and Pumps Current, Charge Sepperation, like I told ISLab in his thread.

If I may, some advice, some get to where you are now, and go Side Ways, never to return to the actual goal, becomming Stagnated and going around in Circles. Focus on the Effect and what can be done to improve the Effect, this can Scale to any Output!

I am going to add you to the Acknowledgements, I think your scope shot shows you know what youre doing now!

Hi Brian
I see that you are a good observer.
In fact I used the 2n7000 for the sole reason that it has a voltage gate threshold of 0.45v , much lower than the 3205 (2v) on the other hand the Rdson (0.008 milliohm) of the 3205 is much better than the 2n7000 (5 ohms ). As we work in very low voltage I opted for the 7000

But sometimes we have to compromise and don't be afraid to try as you do so well. 
Chris has also experimented a lot on this little board and we are still experimenting, we don't give up.
Jagau

Brian posted this 20 January 2022

Many Thanks Jagau

I had been considering if the timing of Q1 could improve performance and note that this on/off time is a function of the characteristics of Q1 itself or waveform coming from L2. I note that you used a 2n7000 where as I am using a IRF3205. 

To eliminate this I have tried a 2n700 and can report the results are very similar to a IRF3205.

I also note that with the current coil configuration I can get the supply voltage to sub 2V.

We know we need more voltage to pump current, so next action is to take a turn or 2 off L1 to observe effects.

Kind Regards

Brian

Hi team

Time for a update.

The spike on the bottom of the CN3 sine wave occurs when Q1 turns off which seems to creating the surge into the 100uf cap we are looking for.

I did not change the coils but played with the supply voltage (it seems best around 3v, but circuit design states 9v), the timing of the MC34063, and coil orientations. I managed to burn out the LEDs several times, but was not able to make any improvements or achieve a self running circuit.

Not wanting to disturb the coils and risk taking a step backwards I decided to look at other implementations of this 2 coil arrangement and came across a very simple circuit credited to Mr Z Kaparnik. This circuit is very efficient, self oscillates and produces a interesting waveform on the cathode of the diode. It will run on as little as 0.5V and produce 6V.  

Yellow trace ins on the coil side of the resistor. Blue trace is cathode of diode no load. Supply is 1V

The sawtooth wave caught my attention and felt this was worth exploring further.

It is very good for recharging batteries and runs LEDs with little supply Volts.

Thought this might be useful.

Kind regards

Brian

Hey Brian,

Excellent Work! Thanks for Sharing!

If I may, some advice, closely study what's occurring before you make any changes. Look at the Spike causing the massive Change in the Sinusoidal Wave. Study WHY this is occurring!

Close up Images of the Effect will shed light on this effect! Close observation of what Evades Others, will yield Results, that Others Fail to Obtain!

I am very pleased you have a result that you can work with and gain a Fantastic Understanding now!

Hi team,

Happy new year, best wishes for advancement of knowledge and health and safety to all. 

I received my pot cores and carefully wound as per specifications kindly provided by Chris. I acknowledge your comments on this Chris and respect your work, my aim was to achieve at least the results you have and then maybe advance on that. To that end careful identical replication was my first step. 

The wire lengths specified resulted in 29mH for L1 and 97mH for L2 so I can probably take a couple of turns off L1. But it is interesting to see the results. Supply is 3 Volts. Yellow trace is CN1 and Blue is CN3

As you can see I am now getting pulses on the bottom of the cycle on CN3. I acknowledge that my scope is probably not displaying the pulses accurately as its resolution and possibly rise times may not be ideal when compared to other images of these waveforms posted by various members.

Do you think this is a indication of charge being pumped into the 100uF cap during this part of cycle?

I will make some small adjustments to L1 to see if I can improve on this.

Kind regards

Brian

Hi Team

I have been experimenting further with this simple arrangement to arrive at the coil resonant frequency with the goal of quantifying the performance of the coil so to match it to how the circuit is designed to operate.

In some designs where frequencies are preset this is a handy tool. But with the eternal flashlight designs some challenges are presented. As you might expect if we apply a square wave the resonant frequency changes significantly, then if you change the duty cycle we get still different results. Additionally I note on the pot cores I have been using for these flashlights the better results are in the Mhz range, where many of the primary frequencies of the driven coils are in the Khz and below so it seems we are relying on harmonics or resonant vibrations of the LC circuit to hit the sweet frequency of the coil. Hence why these coils are so fickle to get right!!

I am waiting on a core which Chris has shown to have better results with than what I am achieving so it has been interesting to apply this technique to the various builds and coils and see the results.

Hi team

Following some really good insights posted by Chris on his thread Chris's replication of AndreyMelnichenkos GLED I took a more detailed look at my wave forms rom that build. I am a way short of the waveform required, but I can see evidence of the reguaging Chris is referring too.

For example on my capture below if I zoom more closely to the highlighted area.

We see

Further research based on Chris's Video The Secret Revealed - Resonance Magnetically prompted me to investigate if I could determine the magnetic resonance of the coils I am using above. I set out to measure this using the following circuit as per the video.

These are the results at which magnetic resonance was strongest. Yellow Trace is measuring voltage induced in the Partnered coil and the Blue Trace is measuring the current through the Partnered coil via the voltage drop across the 0.1 ohm metal strip resistor.

I understand that Magnetic Resonance is at its peak when the current flowing peaks. 

Sweeping the coil I find this at 23Mhz as per below.

I believe this would be a very useful tool to ensure our coils are optimized to the frequency we are designing the circuit for. I note also that this resonant frequency will change with the load on the coils. Some work needs to be done to see if a relationship can be found for tuning coils in the circuit they are designed for. 

Kind Regards

Brian

Being mindful of the information provided above from Jagau, I have spent some time to summarize and confirm the performance of the coil and arrangement I am using. As I have mentioned above it doesn't feel as there is enough energy being introduced get a significant interaction of opposing magnetic fields. So here are the details.

I am using the circuit designed by Jagau to drive the coils, which works really well over a wide range of coil inductance.

The coils are 100 turns each of 0.35mm copper on a C-core. POC coils are separate.

Looking at the waveforms on the POC coils with a diode in circuit on each we can see that the phase is opposing as it should be.

I note there is no (or very little ramping) on the wave which I think would indicate low magnetic interaction?

I then changed the load circuit to a alternate design. 

Below is the POC coil now driving the load (yellow) compared to the input coil (blue).

Measurements when I match the voltage across the load to the input voltage show a shortage of current generated by the arrangement. I am not sure if this is valid thinking, in order to be self running it must be able to produce excess current at the matched supply voltage. So in order to measure this effect I used the following arrangement.

I then went back to the original circuit and tested again to verify performance of the 2.

The point of note here is performance with L2 open. 

In summary to me there seems to be a lack of magnetic interaction on the coils.

My thoughts are there needs to be more energy inserted into this arrangement either via higher voltage or higher frequency. Or maybe the coil design is not suitable, wrong core, or more turns required.

Seems at the moment I may be off track to the eternal flashlight.

Kind Regards

Hello Brian


In order to help you in your research I am attaching a document to you which will surely help you to go further.

Hi Team

Well doubling the turns on the primary did not provide the result I was looking for. Is this due to the now different rise/fall time of the relationship between primary and POC coils?

It feels to me that I am not getting enough "smashing" of the magnetic waves in the POC to create the excess energy required. Do I need to increase turns on the POC coils now to match the primary? If so will this result in higher excess energy? That is using 200 turns on all coils instead of 100 turns.

Is the ferrite C-core I am using suitable or should another core be used. Also is the the 0.35mm copper enameled wire suitable or should it be thicker? I see various devices from many builders such as Akula or Andrey Melnichenkos using what appears to be similar cores and wire gauge.

I accept also that the approach I am taking to self power may be faulty thinking. Basically I am matching the voltage on the cap to the input voltage by the load LED arrangement across the L3 coil, then connecting to the power input, retuning a little as the load is now changed, then removing the power source.

At this stage I am not really sure what is the next step to reach this threads goal of an eternal flashlight.

Kind regards

Hi Team

A quick update

As suspected I did have a earth loop creating the measurement error. 

To eliminate I am running the scope off a battery for these measurements. It is also showing some limitations of measurement sensitivity of my cheap scope. I am using a controlled DC power supply for the supply as it has a handy current display as well as voltage control.

Still it seems I am not getting enough current to self run. So considering options I could reduce the secondary turns or increase the primary. The resultant drop in voltage should still be plenty. I respect that Jagau did advise to have the same number of turns on all coils. Please forgive this little side experiment Jagau - I will increase the primary as this is the easiest for a quick test.

Kind Regards

Brian

What is a Scalar:

In physics, scalars are physical quantities that are unaffected by changes to a vector space basis. Scalars are often accompanied by units of measurement, as in "10 cm". Examples of scalar quantities are mass, distance, charge, volume, time, speed, and the magnitude of physical vectors in general.

You need to forget the Non-Sense that some spout with out knowing the actual Definition of the word Scalar! Some people talk absolute Bull Sh*t!

The pressure P in the formula P = pgh, pgh is a scalar that tells you the amount of this squashing force per unit area in a fluid.

A Scalar, having both direction and magnitude, can be anything! The Magnetic Field, a Charge moving, yet some Numb Nuts think it means Magic Science!

The great Nikola Tesla:

Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago by instinct or reason. It has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antheus, who drives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians, and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic? If static, our hopes are in vain; if kinetic - and this we know it is for certain - then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
