Ok, picture this;
My wife is snoring on the sofa while I'm watching that underwater welding program so I wake her up and send her to bed.
She's very sleepy so there's no point in me following her up. When I've finished watching that program I decide to go to bed but I'm so excited about what I've just seen that I can't sleep and decide to watch sexcetera very quietly
.I reach for the remote then realise my standby plug has shut the tv down so I have to get out of bed and turn it on. As I walk to the TV, I stub my toe on the bed leg, howl with pain while hopping round the room and wake my wife up meaning I can no longer watch sexcetera
.Hmmm, I think I'll leave it on standby
.

fuel cell doesnt sound at all right but hang on... An electric car goes faster than a petrol one, cheaper and for longer? So whats the benefit of petrol?[/quote]
Diesel engines have fuel efficiency of 45% and petrol engines of 30%
The Electric motor in a car is 95% efficient but if you add all the other losses in getting the fuel energy to the wheels it paints a different picture
Energy efficiency’s of power stations are 33% for coal & up to 45% for gas. Grid transmission losses 9.5% HV + 15% local (transformers etc) = 23%
A typical charging cycle loses about 20%
Computing that lot gives electric cars a fuel efficiency of only 35%
(all figs approx)
oh & battery's (30% of car cost) have a 5 yr life
Petrol makes money for G W Bush

Jugs - was referring to Fuel Cell technology and not to Lead acid battery, nicad, or nimh batteries being carried in the vehicle. You missed Nuclear, Wind and solar. This looks fun - was involved with several people at the Open University in Milton keynes up until last year and one of the projects was about just this 
My argument still stands, what is the benefit of oil/petrol again?

This first video put here some time back. Standby Video
I wonder if I could use the StandbyPlug to switch off my Portamig? Bah, it wouldn't turn off the gas. I will ask Karl to invent one that does turn the cylinder off. Maybe then he would keep the welders happy too?

To echo the fat bloke from the bank advert, 'it doesn't work like that'

Did a little bit of reading the other day. Am going to change the background colour on my website to to black as opposed to its current off white. I had a thought in mind that a white background would use more energy to produce on a computer screen, so i did a little research.
It seems if we changed the forum from white to black users with a crt screen (tv type) would save 17watts of power, those with an LCD type screen its a much smaller saving of around 1-2 watts of power. Part of it was on Google and the power saving that could be made if google went to black screen with white writing, how much power would be saved world wide. It seems some of that is where people are moaning about G's lack of green credentials,

Google had an "earth day" with a black background last year. Some bright spark pointed out this actually resulted in more energy draw from LCD monitors for the same number of visits. I used Yahoo that day as the black background was annoying, so to be fair to them they did probably save a bit of energy.

the argument on the LCD ones is still out for argument i believe, apparently there really isnt much change in power regardless of what colour they display. The best result apparently gave a 2watt saving from going to a black screen to a white one, same gave no change in power.
To be honest the whole environmental issue is a bit of a joke really, we import so much stuff from the far east, where electricity production is using old style coal powered generators, pumping tonnes of CO2 into the air, as there ones aren't as heavily regulated as ours. Then we ship the dam stuff half way round the world, pumping tonnes of CO2 into the air to do it.
Truth is i believe there is good money in developing environmentally friendly power sources over the next few years.

wow, irondarren - thats a really good point - I mean REALLY. I used to program a Commodore 64 (oh those were the days) in assembler machine language. And it alway drove me nuts when I put white text on a black screen. It would always produce a BUzzzzzzzz through the telly speaker. Seems you have answered the question I had in my head for more than 22 years!!! (yes I know I am very sad!!!)
The question was why does this happen? Must have been the change in power and bad earthing in old 64's- logical of course.
Back to today. I have only LCD screens in use and its not very good for your eyes to look at white text on black screen.
And as for power - well I constructed a bike with an altenator on the back wheel. The wife is currently keeping fit on it while I type.

i often thought you could beat child obesity if you made the TV peddle power
That noise was out of the tv, not the 64. It was caused by the scan guns being turned off and on too rapidly for the old analog switching circuits and overloading them
I had a program on a zx81 which turned it into a crude musical keyboard (and those of us who remember, the zx81 had no sound circuitry at all), it basically drew big bands of black and white of varying thicknesses to make the tv buzz at different frequencies depending on how far out of the normal range they were...

MrFluffy - oh what do I know? I do know when you Poke 54296,15 (to open up the sound channel) you could always hear the cassette tape through the telly speaker. Did you see this amazing site by stoneoakvalley? http://www.6581-8580.com/ Always thought the noise was something to do with the TV modulation. First computer was a zx81. Facinating bit of kit. Worked perfectly as a door stop too.

Im past me sid/hubbard days
By the time cbm got around to screwing up the 64 with the chip revisions and all that +4 nonsense Id moved onto the amiga a500 anyway and was busy revelling in btst #4, $bfe001 instead of half a page of assembler to read a joystick button port state...
Happy reset
darren, those dirty plants are probably making electricity to make the green goods that everyone wants us to replace our old dirty variants with too
