can you derive 12v from 230v without heat generation.( voltage conversion with out heat generation?)?

Question

without wasting energy in heat disipation while conversion of 230/440v to 12/20v. because it increases heat load from computers, and such devices who gives out enrgy in terms of heat, and i think its lost of energy(electricity) which we produce after great cost(environmental losses)

Answer 1

i believe this was the promise of superconductors but as far as i know (and i don't claim to know alot) it needs to be cooled with liquid nitrogen (not very cost effective) but u get the effect of 0 voltage drop i believe (ie 1 to 1 power ratio) also what makes something superconductivity possible is an atomic properties (orbits?) i believe i don't really have any experimental experiences but i know the cooling limit has be raised over the years using different combination of metals.... so in short possible but not very cost effective almost to point of being unpractical

Answer 2

A transformer will allow you to increase or reduce the voltage in a line, however the available current will be increased. Now for the problem transformers have some inherent loss of power to heat.

To minimize power lost to heat transformers usually has a iron core which promotes the transfer of electricity between the coils. Cooling the transformer will also serve to reduce the loss to increased impedance in the wires caused by heat.

However you will not eliminate the loss from heat, if you do get a patent you'll be rich.

Answer 3

I haven't seen the Dibiase boys, but I like Cody Rhodes' potential. He's already got the gifts to be one of the great in-ring competitors of his time. He just needs some more time to mature and figure out his personality. I think if he can be half as good on the mic as Dusty is, there should be nothing stopping him from being a multi-time World champion. I don't like DH Smith. He has way too much of a baby face. I don't think he has the personality to make it. I saw him selling in that Cena/Orton vs. Raw match a few weeks ago, and he had some of the worst pained facial expressions I have ever seen. He oversold it too much. Of the ones I have seen, Cody Rhodes looks like he has unlimited potential. I think DH Smith will be at best a midcarder, Teddy Hart will never amount to anything because of his attitude, and I'll have to wait and see any other potential 2nd and 3rd generation wrestlers before I form an opinion on them.

Answer 4

short answer: no

long answer: you will always loose energy to heat when converting or even transmitting electricity, no matter how efficient your system is

Answer 5

Nope!
