[OT] "How Green Is Your House" and TV watching

I started on 2400, but I've heard of 300 baud.

In 1977, when I started in what became known as IT, our modems were

This has already been done to death in a recent thread here (uk.comp.homebuilt) but in a nutshell the conclusion was that any switching them on and off several times a day makes no difference since computers are invariably replaced long before the adverse effects of power cycling would be felt.

There is also evidence that leaving a CRT on continuously (as opposed to using standby mode or off) will actually cut its life by a factor of 2 or 3 because the tube life is dependent mainly on how many hours it is on, with the phosphor brightness halving every 10-15000 hours.

Not necessarily. Big LCD or worse, plasma TVs use considerable amounts of power. A CRT TV with 100 Hz refresh also, as do wide-screen CRTs. The best I could find when shopping for a new 70cm TV two years ago was a Philips 50 Hz with 4:3 screen , which uses 60 W active and 1 W in standby; and it has a real "off" switch which we always use. And the next one up (50 Hz, 4:3) was

I've measure some of mine. A new Aiwa small audio system uses 9 W in standby, in 'eco' mode is about 0.5 W. A Yamaha livingroom stereo takes also around 11 W in standby, and you cannot switch it off. A Sony VCR uses 12 W in standby. A Whirlpool microwave 10W in standby. All these come from the display type, which is not LCD but old vacuum-tube type technology which requires a filament to be on if you want to see something. I'm sure if you have a clock radio with this kind of display it is just as bad (I buy only LED-based clock radios). 10 W on standby means 85 kWh/year! I find this ridiculous. I am not interested in yet another clock on the micowave or stereo or video. I would favor legislation that makes it mandatory to supply the standby power consumption in kWh/year , that would get people's attention, I'm sure.

That's right, big large plasma screen, surround sound hi-fi speakers, dvd player and Sky Plus box all connected together by what looks like three plates of spaghetti and what furniture there is knows its place.

Bliss!

It's been done to death in lots of places.

Not "invariably". Only in houses which suck Bill Gates' c*ck.

Certainly.

Even though I have the expertice necessary, I wouldn't waste my time on a $40 VCR. I have far more important things to do with my time (and that includes tipping a beer or two). I don't waste a couple of hours (vs. $19) on a Saturday changing the oil in my car either. I have other "cleaner" things to do, like staining woodwork (this weekend's task, since it was a wash-out).

There's never more than 1 hour's worth of watchable TV per day anyway.

And presumably the notion that criticising the amount of time/energy consumed in watching TV via a TV programme is hypocritical never occurred to her.

Are you asking us or telling us?

Then you should leave your car or truck idling all the time, Everyone knows that most of the wear and tear is done while the engine is warming up. On the other hand, electrolytic capacitors have a limited life and are slowly destroyed by heat. I see a lot of dead PCs with defective electrolytics. I put in about $7 US in new caps and they are ready for a new home.

BTW, I have dozens of PCs in, and around my house. There are three at my computer desk right now, sometimes there are five running at once. There is no way in hell I'll leave them all running all the time. When I finish my home network there will be about three dozen live ports scattered between five buildings. Not only does leaving and unused PC on waste electricity, it makes the air conditioning work harder, so you pay for it twice.

First of all, the speed is specified in Bits Per Second, not bits. The width of the data is specified in Bits. 800 bits would make for a very odd data buss.

Some of the more common speeds are:

Even lower baud rates were used by current loop teletype machines.

BTW, my first hard drive was a full height 5.25" 5 MB that sounded like a vacuum cleaner when it was first powered up.

a) I regarded it as a "learn how to repair stuff project" with no negative consequences other than time expended, and therefore "fun" (for certain values of "fun", I grant you...)

b) all the modern VCRs I could find were rubbish; cheaply made from lots of plastic, dubious picture/sound quality and limited input/output connectors.

Yeah, I pay someone else to do oil changes, too. That's "not fun" in my book.

Conversely, electrolytics will also degrade if left for long periods unused. As the oxide layer thins the voltage capability drops, and the capacitance increases!

When I bought my car, the previous owner gave me a stack of new oil filters and washers for the drain pug, which left me feeling obliged to do my own...

After my own personal "Exxon Valdez" incidents, I think I may skip doing them in future...

There are not many VCRs anymore for $40, and the few to be found, are total junk. (USA, Utah)

In the second, more important place, I am weary of buying new VCRs, with different remote control interfaces, different on screen features, and other stuff that you just get real used to. I would fix it first if I could, even tho I don't drink.......

So, how many decades are you going to go between using your computer? I have electrolytics that are over 50 years old that still measure the right capacitance, and have a very good ESR.

Very poorly made caps will degrade without being used, but they are the same ones that have a short life due to poor design and materials used in their manufacture.

I switch on my old test equipment for an hour or so every few months, to remind the capacitors not to go leaky. Apart from that, I switch a device off if it will be unused for an hour or more.

Unfortunately our kids are educated by advertising companies, who bullsht them as far as they can, and schools dont seem to tackle it at all. They then become adults that are so misinformed about money as to be bordering on deluded, trained to give all their money away for junk at any opportunity they can find.

even when its known to increase the rate of deaths, accidents and costs.

The basic problem is we live in an ignorant society. At least computers are helping quite a bit with this.

Correct, but baud bps.

^^^^ s/buss/bus/. Buss is something you did with a pretty young girl in the back seat of a car, many moons ago. ;-)

You forgot 134.5 ;-)

No, those are bps numbers. Baud is signal transitions per second. Bits per second is then the baud times the symbol size. 1200bps modems were

I've never seen anything slower than 75 or 110 baud. The A/KSR33s were

Sucked, eh?
