We're all connected to the same cables, supplied from a multitude of sources through the National Grid. But I may have chosen a different "supplier" to my neighbour, with a different billing structure. It's the lunatic side of Thatcherism, trying to leech multiple profits out of one service. |

I'm assuming the idea is they monitor the type and quantity of power a supplier generates and co-relate that to the consumption of their customers before allowing them to claim it comes from renewable sources. -- *Great groups from little icons grow * Dave Plowman London SW To e-mail, change noise into sound. |

Most of the place is a bunch sunnier than the UK. Here in Sydney, in the dead of Winter, I get around 6 hours of full Sunshine per day. In Summer, it's more. Much more. Moreover, the popular choice right now, is to couple the cells to a grid connected inverter. Whilst generating surplus power, the meter will run backwards. When consuming power from the grid, it runs forwards. The idea is to generate more than one uses. The power company is required to pay for the surplus. In reality, I don't expect to generate surplus power. Not yet. When I started this journey, I was offered some second hand batteries (really good ones), which I figured on using for a Solar/battery array which could supply my power for those times when blackouts occurred (reputed to be sometime in the next year or two), but the whole thing got too hard. And to claim the government rebate, one must use brand new equipment. Bloody BP. They have the Solar industry by the short and curlies. I spoke with my mate today and he tells me that BP Solar can't keep up with the demand (in Australia). There is a serious waiting list for cells. -- Trevor Wilson www.rageaudio.com.au -- Posted via a free Usenet account from http://www.teranews.com |

I bet the power switch will war out before then. The amp will be fine, but it just won't trun on. **Depends on the electro. So-called 'computer grade' or mil-spec caps are typically rated for 100,000 hours @ 105oC. The types of caps used in domestic equipment are more likely to be rated for between 5,000 and 10,000 hours @ 85oC. At the lower temps found in domestic equipment (say: 50oC) you could expect roughly 4 times longer life. That equates to around 2.2 years of continuous operation (worst case). Assuming, of course, that the caps have been designed and constructed correctly. Some will not last that long. Some will last longer. Some localised heating can occur inside amps, which raise the temperature of caps to very high levels. I've seen designs where resistors, adjacent to caps are allowed to exceed 140oC. Those caps can easily be operated at 100oC without the amplifier being noticeably warm. BTW: Most bi-polar caps (the type found in most speaker crossovers) have a rated life of around 2,000 hours. Sobering thought, huh? More seriously, of course, is the collateral damage which can be caused by a failing capacitor. The gunk inside can be quite corrosive. Moral: When not in use, turn it off. What's about equipment with "standby" mode? **For me, I turn stuff off, with a 'hard' switch, wherever possible. Others may not share such an approach. For many items, with a (say) 1 Watt standby power, it's pretty much academic. Many items consume much more power when in standby, however. They are the real culprits.

They will have premature capacitor failures and they add to the greenhouse problem. -- Trevor Wilson www.rageaudio.com.au Agreed. As a generalisation, anything with a mains transformer will draw a couple of watts worth of magnetising current, less for toroidals, more for laminated transformers. As with all generalisations, there are plenty of exceptions, but equally, many (most) will be along these lines. Added to the minimum magnetisation of the transformer, then there is the power drawn by the standby circuits themselves, so overall, you can expect several watts dissipation on standby. As an example, my Meridian active 'speakers draw 6 watts each on standby, 10 watts at idle. Equipment with Switch-mode power supplies can be made to draw less power on standby than conventional linear supplies. For example, my cheapie DVD player draws 2 watts on standby.

There will always be people who delight in constructing arguments against it though :-) I recently had a look at my REL Strata 5's power consumption, having not bothered too much about it, advertised as it is with 'power starvation technology', and 'maximum power saving at rest'. Measures 6W at idle, against the 4W in the spec. Not insignificant IMHO. Rob |
