ohh...well apparently I need a new glasses

I think it's good enough in my opinion, but it will be nice if we can like or dislike a comment. (kind of like facebook except they don't have a dislike option there.)

how about an airplane? couldn't we fly an airplane to that level and then used that energy to power the airplane? or something like that

how about a surveillance camera, are they energy-consuming since they are to be leave on (not standby) for 24 hours a day?

can we harness the energy of the appleton layer due to its high concentration of free electrons and ions?

when you plug a power cord into an outlet, but when you don't connect that power cord into (let just say a laptop) where does that energy goes? Do all of those energy transforms to heat? I heard of the term "save energy, and unplug your electronic when they're not in use"(or something close to that) a lot.

yea that's kinda what I'm asking. How does it produces voltages in response to mechanical stress?

piezoelectric materials produce voltages in response to mechanical stress. But if you a constant stress, will it produces constant voltages?

and does all electromagnetic waves have the same amplitude?

E equals mc 2 proved that mass can be converted to energy. But how?

since it would emit no radiation then no energy will be lost? or is there another way the energy can be lost for moving negatively-charged ions?

sorry but what is impedance?

Wait, i went and search on it( the Bremsstrahlung occurs when the electrons is deflected by an atom- thus emitting radiation.) So does that mean if negatively-charged ions were traveling in a vacuum, then it weren't emit radiation?

how do you calculate how many revolutions a certain motor will make under a certain time frame and voltages? Or how do you calculate how much electricity will be produced from a dynamo under a certain amount of revolution? Or how much energy will be produced from an electric generator under (certain) motion? I want to figure those things out but don't know how to start. (sorry if I put this on the wrong post;it just seem more suitable than all the other one)

But is it possible to make a perfectly efficient self-sustaining closed loop system where output equals input? (let just say you don't connect it to anything.)

wait... voltage equals IR. By decreasing I, you will get less voltages. Or do you mean that a transformer increases the volts by decreasing the current and increases the resistances. So basically by increasing the voltages only the resistances is changing?

what is a closed loop system? how about a transformer? It created more output energy since the increased voltages resulted in more amps( though the energy will be lost at a faster rate due to higher resistance).

how does perpetual motion defied the law of physic and the law of thermodynamic?

is there some way in which I can calculate the direction the electrons will go after being ejected from a metal as a result of photoelectric effect?

voltage equals I X R So in a transformer, you increases the amps but also increases the resistances-which with a higher resistances it also decreases the amps. So what is the point of a transformer then?

but as the energy loses and the voltages drop, the transformer will bring the voltages up again right? by the way, does the electrical resistance in the wire also converts the electrical energy to heat? and then the heat will convert to EM waves?

what do you mean? how are the energy lost? and what is the resistance from that system?

On the primary I can produce 120 volts and on the secondary i can create 240 volts. I placed a motor that will used up 120 volts on the secondary wire-which will turn the voltages of the current back to 120 volts, and then I connected that wire back to the primary. Wouldn't that creates perpetual motions?

when light slows down in a glass tube, will its wavelengths change or stay the same? since light slows down in a glass/a different medium, shouldn't its wavelengths changes accordingly to it?
