RMweb Premium 45156 Posted January 13, 2020 RMweb Premium Share Posted January 13, 2020 Morning All Just a quick check in as I'm off to LASAR soon, via the bank and Lidl, and Lily still needs her second walk. I've managed to pick up on all the posts, and they are all rated. Interesting comments about electricity and methods of generation thereof make my brain ache a bit. As usual, I offer the usual generic greetings which are meant most sincerely. Regards to All Stewart 14 Link to post Share on other sites More sharing options...

Heating elements are typically AC but it's not so difficult to change them. Presently, all of them have transformers connected to the plug, So the DC won't work! I was trying to think of a single appliance that benefits from an AC supply. The only one I could think of was fluorescent tubes and they're obsolete (and environmentally nasty) anyway. I doubt there are any induction motors on modern appliances - even the washers and dryers. I don't know about the motor connected to the pump on the refrigerator. I'm not planning to take mine apart to find out! I expect any variable speed or small form factor motor is already a DC motor. 3 1 6 Link to post Share on other sites More sharing options...

It's a matter of time. If you want to produce a product that will work anywhere in the World it better not depend on a voltage and frequency. These days there is really isn't any need to assume either of them are constants. 6 3 Link to post Share on other sites More sharing options...

tigerburnie Posted January 13, 2020 Share Posted January 13, 2020 In the Outer Hebrides they could just burn all the crap laying all over the islands and generate some electrickery from the heat, untidy burgers those crofters. One thing to add to the AC/DC(no not the band) debate is 'elf 'n' safety, DC is flippin' dangerous even at low voltages. 8 1 Link to post Share on other sites More sharing options...

RMweb Gold Kingzance Posted January 13, 2020 RMweb Gold Share Posted January 13, 2020 Caught up and not too much from this end. I would add into the wind turbines debate that certain local authorities saw such farms as a great boost for their coffers and actively encouraged proliferation even in low wind areas, just as long as the councillors didn’t actually have to live alongside them. I like the idea of offshore farms because, although harder to service, they don’t consume land and they are clearly forming minor marine conservation areas in their own right. If the turbine owners are being paid for whenever the turbines are available rather than when they are generating, the business model is unfairly tilted in their favour - hence plenty of turbines and many seen stopped! Other than that, hope the sufferers are recovering, a few seem to be missing. Has anyone heard from Andrew of The Boring Borough recently? Instructions about to be received, c u later. 13 Link to post Share on other sites More sharing options...
RMweb Gold Popular Post grandadbob Posted January 13, 2020 RMweb Gold Popular Post Share Posted January 13, 2020 Good morning all, Some blue sky and a bit of sunshine at the moment but forecast to become wet and windy later this afternoon. KZ I believe Andrew said a few days ago that he was going incommunicado for about a month and giving all forms of social media a miss. G word has been mentioned here but I won't be partaking. I am visiting The Shed to allow The Boss access to garden tools but I won't be muddling. I will however look at the layout and try to see what I'm doing wrong. Everything springs to mind. Have a good one, Bob. 4 1 16 Link to post Share on other sites More sharing options...
RMweb Premium PhilJ W Posted January 13, 2020 RMweb Premium Share Posted January 13, 2020 Morning all from Estuary-Land. No ones mentioned two methods of power generation that are in one case renewable and the other nuclear but far safer in many ways. The first is tidal power, a lot more expensive to build than wind generators but reliability is guaranteed (if built properly in the first place). The second is thorium, a nuclear fuel but far safer than uranium. If Fukushima had been thorium powered it could have been switched off before the tsumani hit. Tidal power stations would naturally have to be built offshore and where there is a strong tidal race, the East Coast and Bristol Channel the first already has the infrastructure for bringing the power ashore from the wind turbines which in turn could be moved to the artificial islands built around the tidal generators. Thorium generates energy in the same way as uranium but whereas uranium gives off energy in the form of radiation naturally and in a nuclear power station is controlled by carefully (and slowly) inserting graphite rods thorium only gives off energy when it is bombarded with electrons. Another advantage is it does not produce dangerous by products such as plutonium. As for DC domestic supply many devices that run on DC have the power and voltage changed at the socket via the plug connected to the power supply. For many such appliances its a simple case of exchanging the plug. 9 1 2 Link to post Share on other sites More sharing options...
Sir TophamHatt Posted January 13, 2020 Share Posted January 13, 2020 I think I've come to realise that some people are very strange. From the tens to hundreds of people I sell tickets to every day, there are some that think because they don't know something, they think I will think they are thick. And so, because these people don't know something, they seem to think it's wrong or difficult. Not sure why that is. Example: Lady comes in to collect ticket. She asks whether parking can be pre-booked. I said there was no parking at the station. She pointed to the car park on the other side of the railway. I said it was council run so I didn't know anything about it. Lady then looked at me like it was my fault she didn't realise and made that grumpy sort of huff noise. Maybe she was just embarrassed about not knowing. I don't get embarrassed that I don't know anything about car engines, so not too sure I understand. But the more I see things like this, the more I accept other people are just strange 10 2 7 Link to post Share on other sites More sharing options...
RMweb Gold Tony_S Posted January 13, 2020 RMweb Gold Share Posted January 13, 2020 Morning all. It seems to be a day of gentle breezes and sunny intervals here. Nothing happening of an awly warning nature. Nothing much happening of any activity to be honest. I suspect Aditi will suggest a walk somewhere at some time today.

RMweb Gold 81C Posted January 13, 2020 RMweb Gold Share Posted January 13, 2020 (edited) Morning All Patchy sky cold breeze One lot of laundry in, the bedding I shall do battle later with the duvet leaving it out to air, I have bought a new bedding set I'll put that through the wash before using it. The monster dog will be taken care of mid-day I'm feeding him so he behaves himself up to that point it also when he gets shoved off out into the garden once he starts rough play. This week is my day out with Czech the girlfriend she wants to go to Portsmouth, OK by me I've not been up the Spinnaker Tower yet still it's her choice for a day out any-one know of a decent restaurant down that way.

RMweb Premium PhilJ W Posted January 13, 2020 RMweb Premium Share Posted January 13, 2020 Plenty of eateries in Portsmouth but the only one I have experienced is the pub on the corner right outside the dock gates (can't remember its name). Food was pretty good and quite reasonably priced, well it was 6 years ago when I took a party down there to visit the Mary Rose. 11 1 Link to post Share on other sites More sharing options...
Coombe Barton Posted January 13, 2020 Share Posted January 13, 2020 The channel between Scotland and Ireland is about 100m deep. The English channel is about 34 metres. They filled up at very deferent times after the last Ice Age, which is why there are no snakes in Ireland - they hadn't reached what was to become mainland UK before Ireland became an Island. People proposing the bridge or tunnel do not seem to be engineers. 12 5 1 Link to post Share on other sites More sharing options...

I'm a fairly regular traveller to Portsmouth. If going to the Spinnaker Tower then Gunwharf Quays has a fair choice. I'd suggest "The Old Custom House" (Pub-style) or "Loch Fyne" (Fish) for decent food - both in the Quays and both adjacent to (what I assume) was once a dry dock (appears as 3 rectangular areas of water on Google Maps). HTH (Caution: Gunwharf Quays is full of shops - many upmarket. It could get expensive....) 9 1 1 2 Link to post Share on other sites More sharing options...
RMweb Gold PeterBB Posted January 13, 2020 RMweb Gold Share Posted January 13, 2020 4 hours ago, Robert said: In my humble opinion, Nuclear is a mistake, if something goes wrong (which it can) the price is too high, but long term coal isn't an option either. I suspect that this is a problem that will haunt us for many years to come. After all, everyone wants the lights to remain on. Have a good day everyone... The raw material for nuclear is available, it requires less overall space and the 'waste area needed' is minimal - not sure what all the fuss is about. Compared to the dreadful windmills that spoil great areas of the countryside, but which in some parts are necessary, I think that nuclear is the best solution and are we as a country aware that currently we import a tremendous amount of nuclear generated electricity from France? I must declare here that I have experience of working with radio-active material and have also walked on top of a nuclear generator in the days before it was 'mothballed' and also think that the Windscale 'demonstrations' and exhibition is 'fixed' against a nuclear future in its presentations.
