Only the brain dead can't see that the cost of renewable energy makes it unviable for heating. Direct solar for DHW might make sense, It doesn't in Britain. particularly if no mains gas and on well insulated new build. Electricity makes a lot more sense for DHW, because its ideal for storage hot water because it evens out the load on the coal fired power stations and makes them run more efficiently. For thermodynamic reasons, it's a bad idea deliberately to convert what is effectively mechanical energy into heat. Night storage heaters were popular decades ago when coal was relatively cheap. There's more wiring, but with smart metering I suppose we might see a bit of a come-back. Nothing to do with smart metering - they're just crap In the future smart meters will turn things in when electricity is plentiful and cheap. Nothing to do with time if day. No it'll do the opposite. What they want is to use green energy which we all know costs more to produce and when is that most likely to be most available ? You really are a dimwit. but still brighter than you. In the future renewable energy will be the cheapest. In the future when it is cheaper then that's when it'll be best to use it, but time travel isn't possible so will have to wait until the future gets to us. The energy source is free. Capturing it isn't. Life is free too, food is free, air is free water is free, sex is free. We will use it when it is available. and we won't use it when it isn't. |

They encourage the consumers to use their higher power consuming devices when the system has surplus power. There seem to be two interpretations of the term 'smart meter' here. The present generation aren't particularly smart and AIUI are incapable of controlling individual circuits within the home. OTOH a really smart meter would combine the properties of meter and consumer unit, and be quite capable of switching high demand items such as DHW or CH, which are on their own circuits anyway, under control by the electricity supplier. Smart meters have infinite capability. What they do now is neither here nor there. It can be changed quite easily. They will be able to turn stuff on when there is plenty of (cheap) power. There's nothing here that I'd like someone else to be turning on and off. That'll be an option. So which items will be turned on and off by others, then, harry? Items I'll be pleased about, I mean. Stuff like water heaters and refrigerators. Electric car charging. So it's going to turn my water heater and the fridge/freezer of an on depending on whether or not the sun is shining or the winds blowing. |

According to: http://www.fwi.co.uk/business/hampsh...ks-largest.htm 48 MW solar farm is being built. No info on that page, as expected. Look at: http://renewables-map.co.uk/details....Solar %20Farm for more details: Solar Panels: 50000 Capacity: 40 MW Acreage: 200 More info: 200 acres = 80.9 hectares = 809,371.284 square metres. 40 MW from 809,371.284 square metres. 40,000,000 / 809,371.284 = 49.42 watts per square metre. I am aware that this will be the avaerage over day and night, and over the year. I am aware that solar insolation is very variable. But 49 watts per square metre? Can that really be right? Is the 200 acres the site size, or the combined size of all the panels? I assume I have calculated something wrong. Can any one help? Thanks in advance, David Paste. Background: A not-particularly-technologically-minded friend was pondering whether or not an electric train covered in PV panels would be viable. I said no, assuming an easy to calculate figure of 10 MW for a Eurostar (wikipedia has values ranging from 3.4 MW to 12.2 MW). I was assuming that the *avaerage* yearly insolation for the UK was 1kW per square metre, garnered from: https://en.wikipedia.org/wiki/Insolation so for 10 MW, you'd need (10,000,000/1,000 = 10,000 square metres = 1 hectare = 2.47 acres of panels for one train. A rough estimation for BR Class 373 on the Eurostar gives about 1,000 square metres of roof on a 20 car set. Or 1 MW at theoretical maximum. But it won't be, will it. Curved roof, adverse weather, panel efficiency, all of that. I know that PV panels are not 100% efficient at converting light into leccy, but I was still staggered to see that 49 watts per square metre was the average figure used for that solar farm. And so surely I've done something wrong. The thing is if they find that they are not paying back as forecasted to the bank etc. the company will go bankrupt and the general public will again bail out the banks. |

It will be intresting to see what they do. I guess if you buy a 3kw kettle they could put cirucry in it that will either turn the kettle off or switch it down to 1kw. But that ciruitry might not be cheap enough to include in the £5 kettles you can buy. They will be able to turn stuff on when there is plenty of (cheap) power. |

If a million people put the kettle on when the program ends that's 3 million kW for about a minute. If they power it down it's 1 million for 3 minutes. Sounds good - except that's a rare case, they aren't usually synchronised like that, and if they aren't the energy used around 11am-ish teabreak will be the same. Andy |

EEs one example there are others such as large sporting events. If tehy do this it won't just be kettles either, it could be put into ovens and other high power equipment. and if they aren't the energy used around 11am-ish teabreak will be the same. spread across a longer time period that's the whole point isn't it. |

"Smart meter" is a marketing term dreamt up to persuade people to accept meters which can be read remotely rather than have a man in a van calling round. There's a bit more too it than that as you'll be able to get graphs of yuor actual usage without haviong to type the data into an excel sheet. You'll be able to predict the usage for next year(But only if little changes in that year). I know someone that's been writing software for a mobile phone app. His employer keeps changing what he wants and how it's displayed almost every week. As a further part of their bull**** they try to persuade you that by sitting in your garage or under the stairs watching the meter click over you will somehow magically save electricity. You won't magically save it unless you take action to save it. I don;t have to sit under the satairs I have a woreless unit that gives me a digital readout of how much power I'm currenly (pun intented) using. I can even see it go up by ~9 watts when I plug my ipad into the charger. Sometimes it's as almost as excitoing as watching the ads on TV. |

A rough estimation for BR Class 373 on the Eurostar gives about 1,000 square metres of roof on a 20 car set. Or 1 MW at theoretical maximum. But it won't be, will it. Curved roof, adverse weather, panel efficiency, all of that. I know that PV panels are not 100% efficient at converting light into leccy, but I was still staggered to see that 49 watts per square metre was the average figure used for that solar farm. And so surely I've done something wrong. The thing is if they find that they are not paying back as forecasted to the bank etc. the company will go bankrupt Yep. and the general public will again bail out the banks. Nope, because not bailing them out wont produce another great depression in that case. |

They still have the need they always have done, to balance the load on coal and nuke power stations because you can't economically just them off when there is renewable power available. so will make actually mean the electricity costs more to produce and you're telling me the companies won't pass this higher cost on ? yeah the same day islamic state will organise a flower arranging day.

I was assuming that the *avaerage* yearly insolation for the UK was 1kW per square metre, garnered from: https://en.wikipedia.org/wiki/Insolation That graph and that figure is in fact WRONG. I suspect its in Kwh per sq m per day not kw per sq m. "The UK's annual insolation is in the range of 750€“1,100 kilowatt-hours per square metre (kWh/m²). London receives 0.52 and 4.74 kWh/m² per day in December and July, respectively." If you divide 1000 kWh per year by 365 x 24 you get an average of around 110W/m which is about what the average insolation is given that its dark and night and in winter. PEAK midday midsummer insolation is about 1kW/sq meter. Now the theoretical PV efficiency limit is 67% or thereabouts: In fact IIRC they do around 20%, so the average output of a solar farm is something of the order of 22w/sq m. Contrast a wind farm at maybe 2W/sq m and biofuel at 0.1W /sq m. so for 10 MW, you'd need (10,000,000/1,000 = 10,000 square metres = 1 hectare = 2.47 acres of panels for one train.

I know that PV panels are not 100% efficient at converting light into leccy, but I was still staggered to see that 49 watts per square metre was the average figure used for that solar farm. That is in fact pretty close to the likely figure, And so surely I've done something wrong. Nope. renewable energy is for people who can't do sums. For example, one onshore wind farm that is capable of delivering the same average output as Fukushima did would permenently render an area of land greater than the current exclusions zone *permanently uninhabitable* on H & S grounds, It would be a desert covered in nothing but windmills the size of greater london, and then some. And it would STILL need a thwacking big coal or gas power station to keep to working when the wind dropped. Thanks again.

Of course he doesn't - it would not be classic harry if his linked referenced did not contradict the point he was trying to make. [snip sig, that harry (or his software) were too lame to snip] I see you never read it either. Since your reply was to bert, I had no actual need to read it. However based on your past history of posting links that rarely if ever help support your arguments, I was happy to take his word for it that this was yet another example of you being lazy and sloppy. However since you brought it up, I did go and read it. So now I can confirm it *is* yet another example of you being lazy and sloppy, and can confirm that article that bears no link to the topic under discussion[1]. Or is it a case of comprehension? I have no idea what your problem is, but that would be one plausible explanation. [1] For the avoidance of doubt, a short executive summary: harry made extravagant claims as to all the clever things a smart meter was going to do. Bert said he was unaware of anyone actually developing such a meter, and harry responds by posting a link to an article that makes no mention of smart meters at all. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

It's a fairly normal 'green troll' technique, based on the assumption that no one will actually follow the link: e.g. http://mietar1.tumblr.com/ for more harry ******** -- New Socialism consists essentially in being seen to have your heart in the right place whilst your head is in the clouds and your hand is in someone else's pocket. |
