21. The only idea in here I've ever actually tried to patent: the Privasphere. Essentially a speaker cancels the sound of your voice beyond a certain point by inverting the sound waves of your voice. One problem: it's nearly impossible.
Ah! I had this idea too. I thought that if you put a microphone directly next to a speaker and invert the sound wave, the speaker would emit "anti-sound" and make the place silent.

Ever.
You know, I'm not exactly sure. However, take for example a noisy production facility where you have to wear earmuffs on account of high decibel levels (constantly). When they used the 'anti-sound' thing, when you took off the earmuffs, you couldn't hear the noise anymore, but your ears would still suffer the damage of the high decibel noise.Red Hal wrote:ACU-LP, explain to me how that works, please? Surely if the anti-sound has cancelled out the sound so that you hear nothing, it is because there is no longer any sound to hear? It has been many years since my study of Physics at University, so I'm extremely rusty, but as I understand it, when two waveforms cancel out, the result is no waveform.
Of course, the nature of waves being what they are, it would be extremely complicated to cancel out the entire sound everywhere (prevent it from escaping from a set area completely), but I suppose you could make a reasonable approximation using a suitably fast phased array of transducers.

I actually have no idea how.....just that its happened in practice.

For some reason, I don't think that would work.
Aerogel is composed of 99.8% air and is chemically similar to ordinary glass. Being the world's lightest known solid, it weighs only three times that of air.

Have you ever heard of freedom of speech? So don´t ever try to censor me again. Ever.
Had you however written "I don´t like that word, please don´t use it like this", maybe I would have considered it.

I think this topic has been discussed in this forum not so long ago. I'm pretty sure Galileo (or it might have been Leonardo) first thought about making a lighter-than-air vessel: a vacuum chamber made from copper, which would collapse of course if you evacuated it sufficiently.
But you might be able to do it with a stronger material, especially if the shell had internal supports. A floating diamond sphere would be nice.Another possibility is some type of sealed aerogel structure that was partially evacuated. But if you're going the aerogel route, you might as well "cheat" and put some some lighter-than-air gas in there.

Aerogel is extremely light, sure. But is it porous?
It is; that's why it's so light. But, as I showed, even removing all the air wouldn't make it lighter than air.
Because with hydrogen or helium, you can get a large lighter-than-air volume at atmospheric pressure... so the thing you're encasing it in only has to be airtight, and strong enough to support whatever you're trying to lift... it doesn't have to be especially rigid.nbonaparte1 wrote:So why doesn't it work?

If it weren't for the fact that the Core had already done something similar, I'd make a joke about unrealistic disaster movies.

Well they actually do this in some black and white movie where someone gets given god powers as the gods are betting how long it will take him to destroy stuff.

The sheer fact of that movie's existence is a testament to how much crap people are willing to buy.
