" increase the surface area of your thermocouple, and cool one side of it to increase the output. "

Yip, like adding a heat sink to the one side and a flame to the other side, thatís my plan.

" The Nasa thermocouples have the benefit of having an extremely low external temperature- about 3K "

So how can I be able to make one end freeze by only using electricity ? Iíve seen a example on a ďPeltier effectĒ CPU cooler, it uses electricity to cool down something, without any vacuum pump and some condensers and all the necessary stuff. And itís just a flat piece of white pad that freezes. Weird, can I make something like that, it can also be used to reverse the effect

It's called the Seebeck effect, and so yes, Peltier coolers do work in reverse. Fit a heatsink one side and warm the other, it'll be more efficient than your DIY attempt - but still pretty poor.

PS don't apply your blowtorch to a peltier in the hope of vast amounts of power... al the brazed joints will fall apart.

I must first get a peltier device but, Yes, I know, It will be pretty much screw it up if I do it.
Iíve got no idea how a peltier works inside and will like to build one, if itís possible?

2 peltier devices, connected back to back, it could be nice to see what happens, one takes heat and the other one makes heat or cool again, itís must be 100% efficient to get the best result of course, and itís using only wires to transfer the heat, it would be interesting, to play around with it.

You've got to abandon that notion of 100+% efficiency...

Two back-to-back peltiers will be truly dismal, anyway.

A peltier device is simply a stack of thermocouples connected in series BTW.

Does it contain a couple of wide spreading plates stacked on top of each over, itís not been made clear, or do some just simply not know?

Ok, Iíll drop that 100% efficient for this millennium

I think I have seen this around before, so I'm sure I'm not sharing anything new with you, but have you thought about building yourself a free engergy device. Lots of Tesla's idea's work to a point, they just aren't that practical, and I have seen plans for some of his free engergy devices around before. We built one in school once, the device was essentially as tall as the school, and only gave us a few ma of current and a couple of volts, but hey, it was free. We were able to power an LED with it.

He also had a design for a pump which used the natural adhesion of water on a surface to create the necassary friction to move water along. It had a long series of smooth plates at a slight angle, and was able to move water or I believe gases with much better efficiency that most current designs. I remember reading about a group trying to market a modern manufactured version not that long ago, and they had built a very effecient generator from one as well.

Iíve already tried to built a dozen but nothing works, so I want to built something that can work, and I donít know any tesla workable devices, besides the telsa turbine, itís just a turbine

ďWe built one in school once, the device was essentially as tall as the school, and only gave us a few ma of current and a couple of volts, but hey, it was freeĒ

I would be glad, if you can give me some info how you made that device at that school project.?

Lol. ďthe device was essentially as tall as the schoolĒ for real ?

The only free energy I can get, will be to nick someone car battery

jacquesl-

I don't mean to offend, but if you really want to get off the grid..in this lifetime..you need to start looking at what has already been tried..and failed. Nothing is free, and using all your energy chasing "pie in the sky" technoligies is great fun, as far as mental masturbation goes, but isn't going to get you any practical results any time soon.

Don't get me wrong, there are alternatives, but the ones you've been chasing have already been chased for a long time, by a lot of people. Of all the options I looked at (and I spent the better part of 10 years looking while I lived in the Cascade mountains),a little known invention by Wally Mento was the best option for a low tech, DIY option. Check it out...

Here are the Google results for my search if you want to investigate further.

Rather than building one big wheel, consider putting several smaller ones on a common shaft.

I must tell you, Iíve never heard of this Wally Minto's Wonder Wheel.
Thanks man, Itís dam nice, it looks it might just work, I wonder what type of low boiling liquid with work the best without igniting then to then heated to much, how about Benzene, it evaporates very fast.
