You seem to be misunderstanding somethings.

Directional transmission (and other advances in radio transmission) does not convert signal to noise of vice versa. It decreases the amount of radio waves going into deep space; period.

Furthermore, there is no noise generated by man made radio waves. There is obviously artificial signal (analog TV) and "indistinguishable from noise" signal (current tech). While it is indistinguishable from noise, it is not actually noise, it is a compressed datastream.

Noise comes exclusively from solar bodies. Like the sun, black holes, pulsars, etc.

I was referring to compressed signal that was difficult to distinguish from white noise that you were talking about earlier.

If you want to bring up directional vs. isotropic, you still don't have an out.  While directional emission is certainly less likely to be pointed at Earth, it also doesn't drop off as an inverse square.  Basically, there is less signal initially, but its easier to detect.  I think that SETI is actually kind of counting on directional stuff since the aliens would have to have a massive radio luminosity to be detectable if that radiation was isotropic.

Uh, what?

Of course there is noise associated with man made radio sources.  Anything man made with a temperature above absolute zero emits radio via blackbody radiation.  Any magnetic field with charged particles will emit via synchrotron/cyclotron emission.  Hell, a spark plug going off in a car fires off enough noise to be detectable by radio telescopes.  And they definitely cool parts of radio telescopes to reduce thermal noise from the instrument itself in many cases.

And even if you wanted to call astronomical sources noise (which isn't necessarily usual, but whatever), it's certainly not all caused by solar bodies like you say.  Sure the Sun and pulsars produce plenty of radio emission (black holes are pretty negligible nowadays), but so do non solar sources.  For example, the CMB is a pretty big source of background radiation (you can pick it up with a TV antenna, although most of the static comes from other processes), and it was produced well before any solar bodies existed anywhere in the universe.

In fact, if anything, I'd say that most noise throughout the universe comes from non solar sources.  The CMB accounts for something like 99% of all radiation ever emitted, and its definitely not solar.  Here on Earth its probably a bit different since the Sun dominates everything.

Finally, you don't even have to go astronomical to find other sources of noise.  For example, lighting produces some nice noise in the radio.

In the flesh an F1 is a little noisy....where I stand it's around 120db .... enough to make a 3 ton block of concrete vibrate from sound pressure . [note the headphones on my avatar].  Emission-wise they currently are limited to 18,000 rpm - 4 stroke - 8 cylinder.

That means a plug fires 18000 / 4 x 8 = 36000 times per minute = 36000 / 60 = 600 hz.

Interestingly a simple Google search of the frequency popped up WWV ....the US's oldest continuously transmitting Radio Station....emitting a time code pulse.....been transmitting since 1920.

There's one incontrovertible truth.....Man is more likely to find 'something' out there WITH Seti than without.   Losing it is simply a LOSS to all.

Correct. 

Except that:

1. It is searching wrong so it will not find anything.

2. Opportunity cost, directing those resources elsewhere, such as for space colonization and exploration, would increase our chances of finding alien life moreso then running SETI.

If a radio telescope on another solar system is pointed at our sun, it will not detect a single spark plug being turned on or remaining off over the background radiation.

Also you were explicitly calling radio transmissions noise not referring to noise emitted by technology that is not intentionally transmitting radio signals.

Which is wrong and I already explained why.

1. I brought it up in my first post.

2. I don't need an "out"... I am trying to teach and learn not to "win".

Directed transmissions aren't going into deep space. They are aimed at their target. Also there isn't more of it since it allows for a reduction in initial signal power (power efficiency, limit interference with other signals)

Ok, we are grinding water here and repeating arguments. This is going nowhere, you have your belief and its strong. Moving along, good bye, have a good day and a good life.

So mapping the galaxy is worth the time and money, but checking to see if there is anyone else at those places you map, no matter how slim the odds, isn't? Right. Anyway, don't let the door hit... well you know the rest.

It would be a damn shame if SETI had to shut down. Knowing we are not alone would make such a difference. I'm reading 'The Eerie Silence' right now, it's written by Paul Davies, who is pretty much the head of SETI's after contact division. It's an interesting read, looks like he is leading up to the drake equasion, starting with all the factors that are part of that.

The Drake equation simplified it with an estimated 10.000 possible planets with intelligent life. Eventually one or more will be discovered. Its just a matter of when.

As much as we all want to romanticize, SETI's future coming to an end is almost inevitable.  In the big scheme of things it has to go.  Sorry guys.

Not unless no one cares enough to prevent that. It can be prevented.

What's this 'big scheme'.....the fears and hopes of the God-wallopers that Man is his ultimate creation?...

What a load of ... strawman. I explicitly stated that my issue with SETI is the specific methods they are utilizing in searching.

Also, I specifically said I am not opposed to others spending their time and effort on those ineffective methods, only opposed to spending my own, spending the taxpayer money, and would recommend to others they don't spend theirs if they asked me to. The reasoning behind that being the problem with the methodology employed by SETI in its search.

Well, it's the opposite of the 'small scheme'.... which, in this case, could be missionaries going into the jungle to listen for signs of life of the rare Pygmy tribe, the Wehthafuckahwe's... a clan of 3 foot nothings who live in 6 foot high grass.  Apparently the missionaries place audiophones [summat like those found on old gramophones] to the ground and wait for the sounds of movement.  Personally, I'd find a comfy posie up a tree and wait for the little buggers to jump up and call out: "Weh tha fuck ah we?" 

Yes you did, and even if everything you said was right, you're still ignoring the possibility that they might want to send out detectable signals. Just to talk, or other purposes (read this for a laugh).

What is so useful about mapping the galaxy anyway? Its not like we are going to go there any time soon, and by the time we do we'll have much better ways of mapping it.

Taxmoney is going to be spend on stuff you don't like, deal with it.

The OP specifically mentions Google and Intel as the possible sources of funding. No mention was made of public money (tax related or other). There was also no request made for private or individual donations. To suggest there was would be yet another mistaken/false assumption by direct statement or innuendo.

To do so would probably have immediately triggered spam from "Nigerian Princes".

What identifies Man as a potentially intelligent species, is his unceasing quest for knowledge. The can be fewer greater questions for him to seek answers to than 'are we alone?'.

To dismiss one of the few endevours capable of providing an answer to this question for a small saving in funds is short sighted to say the least.
