@ MrM

Ummmmmmm.....where's "home"?

Our former complacency with status quo?

(Oh, how shall I put this delicately?)

Screw that.
It ain't playing in Peoria either.

Hehehehe.

If I'm being honest with myself I would have to say....

  * ponders *

After spending so long in this car I'm not going to turn it around but you can be your life you're not getting any ice cream when we get to the fairground, and that's final...  And you can put that away!

* Yoinks your PSP *


As for content, I'll chuck something totally off-topic in at this stage myself that's not an indication of how I'm gradually going insane and more an indication of what's driving me to insanity, if no-one minds...

1 ) If you had a speaker enclosed in a hollow chamber, like an egg, and you played music in to it then wouldn't it get hot over time due to the fact that the acoustic wave loses some of its intensity due to heat?

2 ) If you enclosed the original chamber in another chamber the second chamber would heat up slower than the first one as the wave still makes it out of the first chamber ?

3 ) Does anyone know a material that has a very low resonant frequency ?

4 ) Does anyone know what the most efficient method of generating a high power low frequency acoustic wave is?

Yes... That's right... I can't stop thinking about acoustic waves, resonance, wave propagate, standing waves, how you can get a pretty big sound from very little input in certain situations with certain bits of equipment and most of all how resonance seems to favour the .

Think of me what you will...    ...I can't stop thinking about vibrations.

Anyone got any data on this as I haven't made the "ferrite leap" yet (though I am eying a 386 laptop power supply suspiciously)?

Earlier somebody said that it's a real _itch getting the ferrite out of a pc power supply & it wasn't worth it for what they got.

Didn't X00013 say he got his from an old generator winding? I'm definitely needing an answer to sourcing this quick. (since I was apparently side tracked by the "soft ferrite" rumors - so sourcing that may have been a waste of time, I'll know soon.)

edit: as to any actual ideas - I'm too far behind everyone to contribute yet. But the autocad & camera are itching to contribute ASAP.

Yer gonna revoke my Tube account???

If'n the enclosure is egg shaped, I think it'd burn out the speaker cone center before it'd heat the chamber appreciably.

2 ) If you enclosed the original chamber in another chamber the second chamber would heat up slower than the first one as the wave still makes it out of the first chamber ?

<see above>

3 ) Does anyone know a material that has a very low resonant frequency ?

Dunno.

4 ) Does anyone know what the most efficient method of generating a high power low frequency acoustic wave is?

I'm thinking resonance, like a tuning fork, but I really dunno.

Yes... That's right... I can't stop thinking about acoustic waves, resonance, wave propagate, standing waves, how you can get a pretty big sound from very little input in certain situations with certain bits of equipment and most of all how resonance seems to favour the .

So has other people like Tesla and Keely.
You might wanna hunt up a member here by the name of Hans Von ?lieven? as he's way dialed into Keely and those experiments in sonics and tonics.
His site http://www.keelynet.com has some research material  that you might wanna look into, and if'n it sparks an idea or a process, come back and tell us in another thread, or even here, since that's what this is all about.

I thought this Wikipedia article on conservative forces helps understanding: http://en.wikipedia.org/wiki/Conservative_force Some do not agree that magnetism is a conservative force, it depends on case.

<snip>

Thanks for the link---this is an important point, but the disagreement is over how best to classify magnetic force.  "Everyone" agrees that you cannot use magnetism to get free energy of course.

ETA:  Not that you were claiming otherwise---just thought I'd throw that out.
