### No More Electricity!

This is more of a discussion then a question. Lately I have been wondering about the small amount of space that we have on Earth. In those thoughts, I began pondering about Thermodynamics (particularly, of course, the first law). Since energy can't be created nor destroyed - it only changes form - that most certainly means there is a limited amount. There's a capacity. Much like a battery, it can only hold so much energy. The Earth is essentially, then, one huge battery holding millions upon billions upon trillions upon trillions of energy units (it cannot be specified to electricity since it can change form). If that is correct, then my theory makes sense. If there is only so much energy, and electricity is energy, then one day we will reach that capacity, right? Let's create a hypothetical situation - we massively overbuild the world with the biggest skyscrapers that, with the newest technology, go thousands of feet in the air. Standard homes no longer exist, and the smallest of homes are at least four stories. These conditions cover every corner of the world. Power-plants are at a massive draw. Now everybody knows that you can't really "use" electricity for good, for it always returns to another form of energy - it can't be destroyed. So what if, with this extremely advanced society, electricity was used quicker then it was replaced? And this massive usage was continued until all of the energy that is "stored" in planet Earth is being used at one time. That brings me to the real question of debate - doesn't that therefore mean that all power-plants will one day, when this "Complete use of energy" comes, will no longer generate electricity? Is it impossible to believe that they will have no energy left to "grab" (electrical power plants don't create electricity, just generate and convert it"? Now, I may be entirely wrong. This theory could be 153(nice even number) percent wrong, but it's what I brainstormed. Any feedback or debate is appreciated ;)

### electricity generators

Alright, so I'm working on a project, which I won't disclose at this time, and I need as many different ways to generate electricity as possible.  Any and all ideas are welcome, nothing is too weird or unconventional.  The on requirements are it needs too be portable and smallish, in theory it should be easily carried on say, a hiking trip or something.  It also needs to be able, even with some circuitry, to charge a battery.  Ideally 2 AA batteries in series, but higher than 3v is OK as well.  So, I will compile all the ideas and, if they will work for my purposes, I will include it in my instructable I'm working on.  Any suggestions are greatly appreciated and all ideas are welcome.  Fire away!

### Electricity for the challenged

I have a US plug AC/DC power adapter and need to get a European version. The specks on the adapter are input: 120VAC 60Hz 24 W and the output: 10 VDC 1400mA. I really don't have a clue as to what all these numbers mean but understand at a bare minimum I need something with a 10 VDC output. I've looked around at some shops and can find adapters that say 9v 1000mA and others that are 12v 1500mA. Do I need to get the exact voltage (I presume the v stands for volts)? What about the amperes ( I believe that mA is some increment of amperage)? Can I fudge the numbers a bit to save money and time instead of trying to get the exact configuration of the original adapter? Thanks for any help in clarifying this for me.

### Wireless Electricity!

I'm playing around with the idea of wireless power. It should be easily do-able over a short distance- my plan is to be able to charge something like my cellphone through induction, by placing it on a powered surface.. But- I don't know a whole lot about induction, so I was hoping someone could help me out a bit. Here is my setup: I'm using coils from old 5 1/2" floppy drives. I used them once before in a BEAM bot pendulum.. I set one coil on top of another. So far, by pulsing 9v DC through the coil, It sparks a little (because its shorting I assume) and the multimeter in the adjacent coil gives me a small spike of voltage, but quickly returns to zero. Zapping repeatedly gives me at best 2.5v, which is totally acceptable, if only it was sustainable. I've tried using AC 9v.. but I didn't seem to work either. I also tried some different on/off cycles with a BS2.. no luck. Any info would be quite appreciated..

### Electric Gramophone?

I've just had an idea for making an mp3 player disguised as an old gramophone, to be used as a set piece/source of music for busking. Problem is, I can't figure out how to pull off some of the details of making it... Heres the idea as it stands: Have an old gramophone that appears to be playing music from a record, but is actually playing music from an Mp3 player. I figure you could interrupt the signal from the needle to the amplifier without to much trouble, as you'd still need the needle there to make it move along the record as it 'plays'. It also shouldn't be too hard to hide a speaker in the trumpet or even embed it into the side of the gramophone. In an ideal world, it would also be great to have some general controls on the back, to select play lists and the like, and that's probably achievable my attaching it to a standard mp3 player. The tricky bit is that I want to get it to play when the needle is placed on the record, and stop when the record finishes, ultimately with a digital replica of the scratch sound that you get at the end of an old record. Does anyone have any ideas on how to go about this part? because I'm absolutely stumped... is it possible that the answer lies somewhere in using the movement of the needle-arm to complete a circuit while in certain positions? Any thoughts, help, ideas or suggestions would be appreciated :) .
