as in energy,

for the sake of example, is it possible to create 2 kilojoules of energy to become 4 kilojoules and from 4 kilojoules to make 8 kilojoules of energy?? without the usage of 3rd substance but just using physics like machinary or other renewable energy like sun and wind?

so for example you got a small wind turbine that create 2 kilojoules of energy, than using that energy to run 2 wind turbine that produce 2 kilojoules of energy each so a total of 4 kilojoules were produced from the help of only 2 kilojoules of energy. possible?

Yes, it is fundamentally impossible. But most of our methods of producing energy give the "impression" that we are creating larger amounts of energy from smaller ones. A casual observer would contend that energy is being "created" in devices such as engines etc, when actually it is just conversion

That's sucks, where a master graduate couldn't tell whats he doing.

this is normal, but take a look first. the question is how many ampere is generated. I also could do that, by using a DC transformer.

You bold the wrong section la sis. I said IMPRESSION, big emphasis on that. And I'm referring to ppl with little or no scientific background at all

E=MC², understand it ?

Many of you here are laughing your ass off at the TS question and giving him a big NO. I think you all are still stuck wil elementary physics.

Of course you all know the that according to the first law of thermodynamics, the quantity of energy in the whole universe is constant. No matter how the form of energy changes, the total amount when measured in joules is the same.

However, there have been a few phenomenas that seem to violate the first law of termodynamics.  I can't remember those phenomenas anymore but I did have a discussion about it with a friend in uni before. Of course, until now we don't understand the phenomena yet nor are we able to replicate it. But in the future maybe the first law of termodynamics will be proven wrong. Scientist are interested in these phenomenas as if we can reproduce them it would mean an infinite source of energy.
