Your failure to understand any of this stuff is quite comical. You think that all 30471 experiments went badly wrong!

Nah, they're still funded. But have a banana-http://www.swip.ac.cn/cfs/english/In...2003/033.1.pdf |

Err, nope. That would be you.
This does not mean that failures can't happen, and that damage can't occur. Working out how to avoid damage in a full-blown fusion reactor is one of the challenges, after all - especially given that the plasma will have to be continuously vented. Of course, if you keep the laboratory locked so that some clown doesn't break in and try to feed the reactor a banana, the chances of serious failure are significantly reduced. |

Much as I'm enjoying your little spat I'm strugling to see the point of it.

But it's partly me experimenting on the poor soul by setting logic bombs for him. Then when he's struggling with a concept, he'll try to shift the subject. So the UPS thing was a good example. Way back in the '70s, we built proper powerstations. We had a surplus of energy off-peak. So the CEGB came up with a simple solution that vaguely benefitted consumers in the form of Economy 7 and a simple radio teleswitch triggered by piggybacking on R4 Longwave. Fast-forward 50yrs and a similar probem, ie surplus energy not meeting demand. This time, thanks to regulatory capture and clueless feckwits at DECC/BEIS, suppliers get paid to dump energy. And scammers get billions to play with grid scale energy storage instead of looking at how the problem was solved in the past.. |

I'm fairly sure we've yet to encounter a scientific or mathematical concept you haven't managed to completely misconstrue. But I suppose I could have missed one. If I was asked to choose a favourite, I'd be spoiled for choice. But your invention of unidirectional logarithms would be high on the list! |

But it's partly me experimenting on the poor soul by setting logic bombs for him. For example you chuck in a meaningless "0-270 ppmv" CO2 then run and hide when asked about halving of CO2 from 270. You just pick up the dud and throw it again later and duck and hide again when the same question inevitably crops up. |

Not meaningless, and rather fundamental to justify wasting billions on pretending the industrial revolution never happened. Of course if your or nlp could expand on CO2's enery budget, you'd be close to answering the question. Or just collecting your Nobel prize for proving the homeopathic effects of CO2.. Y'know, how less CO2=more warming.But this is supposed to be about energy policy, so avoiding this number- https://notalotofpeopleknowthat.word...s-last-winter/ increasing as energy costs rise. |

This is a really interesting thread. Recently I began to wonder if DS forums were just for angry people with no social lives, but just occasionally you really learn things - Gridwatch being a case in point.

Still only want them to apply when CO2 levels are increasing? |

Yes a range is meaningless when you're asking for a temp drop for an amount of CO2.Quote:

Why not remind us where we said that; oh look, you can't because lies is what keeps your logic bombs in material.Quote:

Fear not! https://notalotofpeopleknowthat.word...ar-panel-road/ Quote:
While the daily production will fluctuate according to weather and seasons, it is expected to reach 767 kWh per day, with peaks up to 1,500 kWh per day in summer. Now being a humble engineer, one would have hoped the assessment would have come before €5m was wasted, and somebody might have pointed out solar panels are unlikely to be able to power street lights, which are typically required when it's dark.Some 2,000 motorists will use the RD5 road every day during a two-year test period. During that time, assessments will be made as to whether the road is capable of generating enough power to run the village’s street lights. Tourouvre-au-Perchef is home to around 3,400 residents. The project is said to have cost €5m (£4.2m/$5.1) and was financed by the French government. (and in other news, snow in Saudi. Which I guess may impact their solar production) |

This is great stuff!
I'm absolutely loving this spat between some obviously very clever DS 'ers!
I cannot compete on their intelectual level but love reading through all the arguements! A site I refer to a lot is the National Grid Status-it gives an absolutely simple over view of everything going on. Today is probably a bad one to knock wind power as its doing rather well but there are very strong winds accross the country! http://www.gridwatch.templar.co.uk/ |

Well.. Like many things, it's not that simple.. So lots of wind, but might be lower demand because we're getting into silly season. But that's a problem with wind. Power when the wind blows, not necessarily when we want it. If there's no demand, windmill owners get paid millions in 'constraint payments' to not deliver power and burger up the grid. T'other issue which the BME version shows is maintaing grid frequency stability, ie 50hz. That gets more challenging with gusting winds.

Wind turbines are, after all, designed with gusting winds in mind but there is a limit to what they can withstand wind wise and this problem will increase with more wind capacity. |

TYep, after years of privatistion disaster, the original ''merit order'' system for power stations, which was ''perverted for profits'', has finally run out of steam, and is now in hot water. Next, gov uk will hav to pay factories to ''close down'' during peak demand periods.
