A World With DC Generators and Transformers

12/10/2008 11:32 PM

It seems to me that the real DC generators and transformes if would be invented, would be the real answer for our today's energetic crisis. For instance if a DC electromechanical generator as producing DC without any electronic or electromechanical comutation, would be possible and also a DC transformer something resembling with those wound step-up and stepdown used in AC fields would be possible, again without electronics involved, our world would look completelly different, don't you? But just taking this possible techno-scenario, how would look today our world?

What's a DC transformer?

Please explain . . .

DC converters exist already and do a wonderful job of efficiently converting one DC voltage to another in applications too numerous to mention. They are also very efficient (80-90% or more) and can be as small as just a few electronic components (much smaller than a transformer of similar output power) if that is what you were wondering about.

A DC transformer doesn't exist as it is not physically possible (for obvious reasons). For a transformer to work you need a constantly changing waveform (or AC = alternating current).

DC generators on the other hand work on a different principle and do exist. They are almost as common as transformers.

Have a look at Wikipedia or do a google search, you should get a few hundred million hits on the above topics.

And "we'll all be drinking that free bubble up and eating rainbow stew." Yea, sure we will!

If you can figure out how to make commercially useful DC without commutation and a DC transformer that is efficient, you will probably bring old Thomas A. Edison back from the grave just to taunt that smarty pants Steinmetz!

I'll bet you voted for "change" too.

Sheesh!

Re: A World With DC Generators and Transformers

Dear friends, I appreciate you kind replays and let me confess with you that I am that type of outbox thinker who actually dare to dream. So my thread was just a simple invitation to imagine that world of how would look like if the DC motor-generators and DC transformers would be possible and nothing else. The energy in general and the electrical energy in particular is in fact a never ending story and I wouldn't be at all surprised for such an outcome from someone's mind. So dear more or less courageous thinkers: #1. "cnpower: that would be great invention." My A: …..thank you! #2. "TVP45: Why would these solve the energy crisis?" My A: ….one reason would be that the DC is easier to transport, store and control; of course there are many other reasons. #3. "Bill: What's a DC transformer? Please explain . . ." My A: …I mean exactly as I said, a step-up or step-down DC transformer wound like a normal AC transformer on a ferromagnetic core, etc. and have the same simplicity as the well know AC one without any electronics involved. #4. "NotUrOrdinaryJoe: I think it would be easier to catch a rainbow!" My A: …did you try?; … or rather win the Super Lotto $120 million, don't you? #5. "jack of all trades: DC converters exist already and do a wonderful job of efficiently converting one DC voltage to another in applications too numerous to mention. etc…..and …Have a look at Wikipedia or do a google search, you should get a few hundred million hits on the above topics." My A: I am not talking about DC-DC converters, but about generating directly from any DC rotating or linear electromagnetic machines without any electronics or electromechanical commutations, as any let say DC chemical sources. But anywise, thanks for your input. #6. ""Turbotroll3: And "we'll all be drinking that free bubble up and eating rainbow stew." Yea, sure we will! If you can figure out how to make commercially useful DC without commutation and a DC transformer that is efficient, you will probably bring old Thomas A. Edison back from the grave just to taunt that smarty pants Steinmetz! I'll bet you voted for "change" too. Sheesh!"" My A: I agree it would be funny. But why me and not you to discover how to? If I could be that man that solves this puzzle, I would first honor Thomas A. Edison's visionary belief that DC should be possible as a primary generated energy. And let me be honest with you, apropos about voting for "change": "I always fight for change, and for that I don't need to vote" #7. "cnpower: dont take it seriously. if yu deal it seriously, yu will be all victims in this hoax." My A: Did you change your polarity? Or suddenly I am involved in a "hoax"?

Serious about what? Usually I like to be serious when I'm dreaming about the future, but meantime I know allot of jokes.

oh, I know only a little of electric tech. Im out of work now.

thats why Im interested in the dc generator and.

and can you tell what you are doing now? s school student? or a worker in a factory?

OK dreamer....since you like to think "outside the box".....how about a useful concept like a gravity to acceleration converter? Talking about how different the world would be if only it were possible!

Converting potential energy to kinetic energy in either direction is easy using motion. And simulating gravity with acceleration is certainly possible but only in one direction (so far....). Kind of like the AC power vs DC power problem.

All we need is a monopole magnet and the world would be ours!

Frankly, I can't imagine a DC transformer that doesn't involve the 4th dimension (time) and motion (the 5th dimention?) in perfect synchronization. Unless, you take advantage of the magnetic monopoles lying around.

Just another question for thought...."How do you clean off a magnetic monopole?"

I think CN power was rite when he said do not fall for this, it is a hoax. I recon it is. I do not believe in miracles but I do believe in facts with proper supporting explanations.

Tesla was a man of high ideas so much so that in the end the US government seized all his unpublished papers and god knows what...and now some of the luckier unis (like MIT) getting his ideas gradually released and turning them into brand new ideas as their own.

As for Edison, he stated it once that his "creations" are about 5% inspirations and 95% perspirations. That's why most of his patents had to be refined or kept them until something new came about, like the AC power and its transfer over long distances as opposed to his DC power supply.

What about yours ideas? How they rate on the scale 1 : 99? - that's what it sounds like to me, if not worse.

Remember, no idea is useful until you put it into practice, so prove your b...point!!!

Just tell me something! Why do you hate simple things in life like sound and vision? Basically these are AC phenomenas in the vastness of the freq domain and DC would leave you cold.

Do you also realise that even the Dc generator works on Ac principle? Its just gets mechanically rectified as your much appreciated Edison's generator did. In fact I doubt if he new that he could have even turned his generator into both AC and DC type, had he been enough cluey enough, which I doubt very much.

Edison was a full on c...because he declined to pay Tesla for improving his Dc power station by saying his promise to Tesla 'it was a jest in a banter'.

I guess you really think well-within-the-box and should let us help you to get released from it.

Obviously the school you went to must have been a real posh one that made you focus on wrong things, don't you think?

How does it change the scenerio ?
Is it not better the way it is with much more efficient AC for generation (of course I dont consider solar or other piezo electric - as I say in one article- using people walking over a piezo mat and the generated electricity is lighting lamps)
That apart - change AC to DC - (already done for HVDC transmissions) - back to AC and distribute.
The advantages with AC is with line commutated inverters and rectifiers, you have much more control over power flow (lest your generator starts motoring). but with DCs generated at each point with different voltages, the feeding to grid may be a bit difficult and we will need a double - converter circuit instead of a simple rectifier or inverter.

Considering that energy storage will be the next major breakthrough issue, and that most storage either chemical or mechanical is essentially DC in nature so far, it does this community good to postulate on a little "crazy talk" once in a while.

My contribution to this discussion is that AC and DC are related in ways that neither will be exclusive of the other. Each has it's own special advantage in certain functions.

The main drawback is the energy losses that occur when converting one to the other and vice versa as technology now stands. When the technology emerges that reduces these losses to insignificant values then the best features of both will better serve mankind.

So I'm in favor of cutting Dumitru some slack since he made no claim, he only asked us to imagine. Imagine that.

Finally, someone who got the point and took me out of from "others prior-art's cage". Thank you for keeping me out of their box. So, lets dare!!!
