There is a move away from them, the trouble is that the cost less to run at the moment, I know that fuel is not a simple cost, but we are talking about accountants (sorry to use such language). -- Ian G8ILZ There are always two people in every pictu the photographer and the viewer. ~Ansel Adams |

Electric buses and cars are the answer, but they seem no nearer to becoming popular than they did 10 years ago! So the pollution can be generated out of the cities at the power stations, so we can have it instead of you. Bugger that! ER!, NO, the power stations if not using renewable full can be equipped with effective filters whereas such filters might be too heavy for use on a vehicle. -- Ian G8ILZ There are always two people in every pictu the photographer and the viewer. ~Ansel Adams |

What if the driver is taking an empty car to fetch people, or driving it back home after having done so? What if the driver needs to be able to carry several passengers, or quantities of luggage, but not every day, and they can't afford a big car for some days of the week and a small car for others?

Rod. Or what if the driver has a physical disability (like myself). I can't walk and rely entirely on my car for getting around. Without the car I am almost housebound. I cannot use public transport because it does not take me door to door. Steve |

I will not switch off any of my appliances from the mains and see how much it affects the leccy bill. Marky P. |

The message

I also use energy saving lightbulbs, and bugger the fact that they have a horrible power factor Only the first generation CFLs limited to 20 watts max to take advantage of the regs pertaining to domestic use permitting such loads to be without a PF correction capacitor would present such a problem. The reason you never saw such CFLs rated any higher than 18 watts was to guarantee that it would keep below the twenty watt limit even at the highest permitted supply voltage and worst case manufacturing tolerances. The more modern electronically ballasted lightweight CFLs have a PF of nearly unity even if the commutating effect of the full wave rectifier on the current is to produce narrow (but still in-phase) conduction angles. The conduction angle would be even narrower except for the fact that our so called 50Hz 'Sinewave' mains supply is quite grossly distorted with the peaks being rather flatter than a real sinewave. (I do hope that the new digital electricity meters (like what I got now) only measure real watts!) They do. To do otherwise would be a serious breach of the regs. and the fact that they're full of mercury and electronics...

"Mike GW8IJT" wrote in message ... "Dom Robinson" wrote in message ... In article , says... "Marky P" wrote in message ... I've got into the habit of switching off all my electrical items (excluding the fridge) at the mains every night before I go to bed. Problem is, yesteday I set the DVDR to record something, then switched the bugger off at the mains and went to bed! Marky P. That will teach you to take any notice of stupid government ******s. That's incredibly presumptious of you, Mike, and possibly unfair by assuming that the government were ******s, there. How do you know it wasn't advice given out by stupid BBC Breakfast ******s? ![]() -- Dom Robinson Gamertag: DVDfever email: dom at dvdfever dot co dot uk /* http://DVDfever.co.uk (editor) /* 1132 DVDs, 347 games, 314 CDs, 110 cinema films, 42 concerts, videos & news /* antibodies, steve hillage, burning crusade, sega psp, norah jones, kylie New music charts - http://dvdfever.co.uk/music.shtml Youtube - http://www.youtube.com/profile?user=DVDfeverDom Sounds to me that you work for the government. The NuLabour scum that form the government are a load of ******s. Regards Mike. So what differentiates you from them? I wave no particular political flag, but I do (really do) think that those in authority in this country are - mostly - capable and intelligent, regardless of political colour. The hoops that they have to jump through and the qualifications they need to get these jobs see to that. Whilst we may not always agree with the WAY that things are done, at the end of the day most of us have no real inkling of the detail of any of these issues, nor are we intellectually equipped to tackle them and to suggest that we know better is arrogance in the extreme. The truth is that most of us, given the opportunity, would not know where to start and if we tried we would surely **** it up big time. As a nation of knockers (of everything) about the only thing that sidelined and inadequate pundits are good for is to continually denigrate the nation's efforts and thus damage all of our prospects. Seems to me that those that criticise without having given it a go and who are - mostly - less well qualified to do the job than those that have taken it on are the REAL ******s around here. |

Fair enough then. I still wonder if the manufacturing costs of CFLs outweighs the power savings; assuming that you replace them when they get annoyingly dim which I suspect is rather sooner than the '8 years' life quoted on the box... I suppose with the number of non-linear loads on the mains (transformers/bridge rectifiers and switch mode supplies) it might be surprising if the mains stayed a perfect sine wave. I've not recently connected a suitable scope input to the mains... always assumed the nasty mains cycle shape you see (by touching a scope probe, for example) was due to poor coupling of the waveform through my body into the scope. Must try a toy energy meter (like http://cpc.farnell.com/jsp/Electrica...sp?sku=PL09564 ) and check out some of the appliances (and light bulbs!) at home. dom. |
