Simple to build isolation transformer that consumes less power than it gives out

[Jack Noskills]

T-1000 or anyone with knowledge on this - a question on using a Variac for trying this.  I've got a heavy duty Variac and wonder if that would be like a 1:1 isolation transformer when it is adjusted all the way to full voltage?  In other words 120VAC in and 120VAC out.  I think I also have a second isolation tranformer out of an old power supply.

Beware, if you dont know how trafos are winded you have 50 % chance to guess correct when you connect lower coil in second trafo. If you put it wrong way you will consume all power in your first trafo. Use a light bulb as current limiter at first trafo.

Or you can skip the first trafo and use enough caps instead, check the other picture I posted. In this case the first trafo will be in the grid somewhere.

the problem is, i am afraid,  that it does not.

You did not find anything wrong in my stoneaged testing method ?

If not then this is the way I see things now:
The World championship soccer game is 0-0, we are at the last minute of extra time on second period. This is the game-of-games, bigger than seventh game of Stanley Cup final, bigger than Super Bowl final, the biggest game there can ever be. The final game. You, barotolougos the goal keeper, prepares to block a penalty shot. All full of adrenaline and ready to block, your teammates are counting on you 'He can do it, we trained him extraordinaly well'. Trevor Buster, nick named 'TrollBuster' prepares to shoot. He knows that after this the game is over, there is no time left. Game-of-the-games will be finished after this, no matter what is the result. There is no pressure on his face, he is calm as the ocean, he has never felt as confident as now. What a wonderfull feeling that is. He steps just one step back from the ball as this is all he needs. He kicks the ball gently, as if it was a golf ball on the green right next to hole. Crowd goes mad, is this guy insane ! Loud moaning fills the stadium as 100 thousand people moan together. 500 million people moans together at their TV sets. We cannot win !!!! Ball starts to move, it rolls and rolls on.

It seems to take forever, you can almost taste the suspense. Ball reaches the goal and stops just after the goal line. Why isn't barotolougos the goalkeeper doing anything ? Oh lord he is just waving hands, seems he cannot reach the ball. Referee comes to check if it was a goal. He walks over slowly, looks on top the ball as that is the only way to see it exactly. Trevor is as calm as before, no sign of panic or fear in his face. Barotolougos the goalkeeper is swearing and spitting, why there is blood coming out of his face ? 'NO GOAL, NO GOAL' he screams in high pitch horrofied voice. Referee kneels down to get closer, suspense in unbelievable, Trevor turns around and begins to move towards center, slowly, calmly...

Referee stands up, blows in the whissle and points at the center. GOAAAAL! TrollBuster scored, crowd explodes, people at their homes in front of their TV sets begin to cry. To win the game-of-games all that was need was just one calm brilliant move, they have finally won the game after hundred years of waiting !

After game it was time for analysis, what in the world happened ! How barotolougos the goalkeeper could not catch that ball ! Slow motion shows that as the ball comes in he moves, so he must have seen it coming. But wait ! Why barotolougos the goalkeeper is behind the net ? You cannot catch the ball behind the goal, you only get mixed up with the net and hurt yourself. That explains why barotolougos the goalkeeper was bleeding. Now who ordered him there ? Pointing fingers turn to coach at the bench but he is not there anymore. He has left the stadium in a hurry and gone exile at north pole. He will never coach any team ever again. He is now history, forever.

This is as much I have to say for any offending posts that are not based on facts, you must be more clever. I hope you have as much fun as I had writing this, but wont respond again to negative opinions. Negative facts are a different story, they move things forward.

I will start my summer vacation after tomorrow, three weeks and no access to net. Meanwhile, the ball is now rolling and coming closer to goal...

Could this project be run using a pair of toroids instead of the regualr trandformers?

Well said, Jack.

Here is my master plan. Anyone who does the above and makes a working prototype should get the second gold medal from Doc, I get the first one as one memento is quite enough. Your device need to give out more than 35 Watts, because that is what I am getting now. Now you will have your name on it and with help of Mr. Jones we go after bigger prizes. This OU prize here first, developer gets 80 % so he can develop it further: bigger, better, badder, well you get the idea. I might take 20 % to cover my own blown up meters and stuff I have spent for this. For bigger prizes I want equal share, just in case I happen to lose my nice job mysteriously. No greed, just that I got 7 mouths to feed. If someone then improves the prototype significantly then we make 40-40-20 split. This 20 percent will then be splitted again later in case someone makes another significant improvement and so on. Then we let anyone do the manufacturing, without anything coming to us unless they want to give. I need no hassles.

Sounds like a decent plan to me -- as replication is the key to good scientific progress (and to benefit mankind) -- I have three gold "medals" as you call them to go to you and the first two who reproduce and verify your discovery. (Which I personally think is or should be of greater value to mankind than the discovery of the Higg's boson!)

I will also be very happy to test for "strange" emissions from a working model, such as neutrons, gammas, X-rays, etc.   I can do this (and at no charge, of course).

Then we let anyone do the manufacturing, without anything coming to us unless they want to give...

Distributed manufacturing in several countries like this is a KEY factor in getting this past the censors IMO -- but I suggest you should at least request a 5% royalty-return on profits taken by others; again just a fair return to the inventor.  You may not be able to enforce such a royalty without a patent (attempting that would be a BAD idea IMO), but OTOH honest builders will be glad to pay such a royalty IMHO.

Thanks again for your willingness to share this openly and boldly, Jack N -- and hope you have a restful vacation.

http://en.wikipedia.org/wiki/Autotransformer would not fit. It has single winding while it needs to be 2 coils on same core. The setup seems is quite simple from first look: TR1 gives power source and TR2 is connected as resistive load to TR1. But because of oscillation in TR2, it gives induction in its secondary and that increases impedance for TR1 while TR2 is under load...

Thanks T-1000 -- I should have known that if I had even briefly engaged the brain from neutral.
