New to the forum, Long time believer in OU

[conradelektro]

Without magnets it ran for just over 6 minutes letting it go at the same place (touching a board) so i'm assuming the drag on the coils/magnets took energy.
Still its one of the first I had and I have quite a few more, I just need to work on a few parts. Thinking about one earlyer gave me a way to maybe improve on the design but im sticking with the simplest version first.

In case you made a conventional invention (something that does not contradict conventional science) just file a patent with the help of a patent attorney, which will cost you initially about 3000.-- EUR for a national patent. Within a year you have to decide whether you want a patent in other countries as well, which will cost you between 10.000.-- and 100.000.-- EUR depending on the number of countries in which you want protection. But even if you will get a patent, you will probably make no money (you will loose the money spent on the patent), because the patent is the smallest problem. Your big problem is production and most importantly marketing. If you are not the money making type, just forget the idea or go to an enterprise with it. But be aware of the fact, that good ideas are usually stolen by the people who have the means to produce and to market something.


If you think that you have discovered something outside conventional science (e.g. an OU device, whatever that means) you should immediately go public with your idea in order to test it by discussion and replication by others. And you will discover within days (if you disclose it intelligently) or within months (if you mess around with partial discloure) that your idea was nonsense, a delusion or an error.

Sorry, this is the hard truth. I observe the "OU scene" since at least twenty years and all alleged OU-devices (or devices allegedly contradicting conventional science) turned out to be nonsense, delusion or error. There is also fraud, but that is easily detected.

By all means do tests, do build contraptions, but be open with it and you will save yourself a lot of time, money and grieve. There is an enormous body of knowledge in science which no man can know all. Therefore you need discussion and replication of your ideas (in case they are really unconventional).


There are limits to science, but they are so far out, that you need huge resources to explore them. The unknown is out in space (dark matter, dark energy) and deep down in the particle world (below the atomic level, yet unknown particles and properties of matter and space). You need space telescopes or a particle accelerator, which is both hard to do at home. Of course there a millions of details in all sciences which still have to be worked out, but you need to train yourself for years in a very special area of science and you also need equipment which can not be set up at home unless you are a millionaire (which I guess you still have to become).

Do not give up, but be sensible and try to have a realistic outlook on the world.


If you want to become rich:

- marry a rich wife or
- sell drugs or weapons or
- buy something for 1000.-- and sell it for 5000.-- and from these 5% you will live well

6 minutes without magnets and 5 minutes with the magnets sure seems to say that the magnets made the device less efficient to me.

Sorry for offtopic but I need help.
I have a few such heaters from old electric kettles : https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcTVpAb-1hcRDM2tOPXCpM4WrCSsLaHohETvGA_4uzYS7O-XcogBhA


I measured they have 26 ohm resistance and 90uH inductance.  They are rated at 230V AC 2000W each


How can I compute heat dissipation of this heater for various AC frequencies  ? I'd like to power them from high frequency inverter without having to store energy in bi capacitor and converting into 50Hz AC, but I couldn't find any article about behaviour of nichrome wire in inductive coil arragement at high frequency.


MarkE , can you help ? I think it's very interesting topic.

Nichrome has a temperature coefficient of 0.04%/C so your 26 Ohms cold is slightly high for say 200C rise.  So we'll figure you had a couple tenths of an Ohm in your test leads and go with 26.5 Ohms hot for R in the equations below which is the computed resistance for 2kW at 230Vac rms.  In order to get at least 1000W from the heating element we want 2*pi*f*L <= 26.5 Ohms, so an f_1000W for you would be: 

f_1000W = 26.5/(2*pi*90uH) = 46.9kHz.

For power at any other frequency:

Use R = 26.5 Ohms

X_L = 2*pi*f*L 
theta = atan( X_L/R )
Z = (X_L² + R²)^0.5.
P_APPARENT52.9E3 V²/Z. 
P_REAL = cos(theta) * P_APPARENT

All that said, I can't think of a good reason to feed high frequency AC to a heating element.  Why not use a HF inverter, and then feed DC to the coils?  230VDC will get you 2kW.

Can you explain how you get the formula for apparent power PAPPARENT52.9E3 V2/Z.
What does 52.9E^3 factor mean ?
How did you got that nice graph ?
