  1. That is why I picked Wind as the RE source. A lot of the E7 period is linked in with nuclear. Now there is a problem. We have to get those locals in Cumbria to keep the waste. Everyone knows it is going there long term, they are just holding out for more money.
  2. I did the maths (roughly and quickly as I am on way out). Seeing we have about 22.3 GW installed capacity (wind only) and that produces around 60 TWh/year. So doubling the wind capacity should just about do it. That is quite achievable in the next decade, the last decade we have installed, on average 13.7 GW. But as @Ed Daviessays, with a bit of management, it could be less. We could currently charge about 3.5 million BEVs without any change, 7.5 million by shifting to night charging. That is for the whole grid supply, not just the renewable element.
  3. I work on 0.25 kWh/mile.
  4. If they are keen gardeners, get them a Dobbies Club membership. It costs nothing, and they may go out for the afternoon. Having said that, I did NOT ask a woman out because she suggested that we met at a garden centre.
  5. Except, for the foreseeable future, BEVs are best because of the better efficiency. Noticed that last year, over 50% of our electrical energy came from renewable and nuclear sources. https://news.sky.com/story/more-power-came-from-renewable-energy-than-fossil-fuels-in-uk-in-2019-11898806 Just got to increase that by 60 TWh/year to cover personal transport.
  6. Had a look, only found one in Norway. One of which is in Redruth, which seems an odd place to put one. Though it has been described as the new Shoreditch (Redruth, not a gas pump).
  7. Would they not just pull the main fuse and leave the, what I assume is euphemism, behind.
  8. How about evening classes in a totally unrelated thing. Something to take the mind off the build. I had a good laugh learning British Sign Language. Now I can get approving looks from a few people when I call someone a noisy wanker. Suspect most if use can do that, but I can finger spell it as well.
  9. It is really about risk, the risk of the initial accident, then the risk of s fuel leak. Then the risk of a fire. Then finally the risk of bring burnt. Probably lower than a liquid fuel car. Ethanol burns with a clear flame. I was at Pocono speedway and wondered why they were cooling the driver with buckets of water. An odd sight.
  10. Perceived is a better description.
  11. There is a testing scorecard for modules https://www.pvel.com/pv-scorecard/ Not bothered to download it.
  12. That is the main reason, apart from shading, I would choose them. I would think that not many installers that fitted them are still around, and how long will the service be supported by the manufacturer.
  13. Apart from installation damage, has anyone every had a PV module break? I have seen one solar slate install that got hit by lightening, but that is the only one I know off.
  14. It is the mas of the thing. One of the criticisms of EVs is that they are heavy because of the battery pack. Mirai has a mass of 1850 kg, Tesla 3 is anywhere between 239 and 3 kg lighter. Now I know it is very hard to compare like for like, but at the moment, HFCEV are just heavy bits of kit. Makes me wonder what they are bothering with all the other drawbacks of hydrogen. I also wonder how fast the hydrogen is produced if done on site. Is it really worth pumping in 100 kW to crack water when it could be shot into a BEV. I know these are relatively short term problems, but there must be a reason why car manufactures have gone down the BEV route, especially considering that lithium cell technology is a lot newer than fuel cell technology.
  15. That could be the Renault influence, which is really the French government, who own most of EDF. I wonder who is pushing hardest for EVs to be the only choice, not that it is a bad thing.
  16. Yes, it was to do with the supply of batteries. But I would have thought that the world's largest car producer (not sure if it still is) could have sorted that in a decade. Tesla have built a factory and delivered cars in about 10 months.
  17. I read a piece in the motoring press that claimed that the reason that Toyota did not make a full EV was because a greater CO2 reduction could be made, overall, with PHEVs. Last week the chairman of Honda said that customers wanted Hydrids at the moment, not full EVs or, the worse of all worlds HFCEV. With a product cycle of 7 years, this is probably a prudent commercial decision.
  18. I was almost directly quoting something I heard recently. I think it was an aging biker in a supermarket carpark. He started then going on about volcanoes and cows, Chinese and Indians. It is that sort of conversation that makes me want to have a reasonable and understandable response to.
  19. Says in that link that it is not very good for calculation the liquid phase. So shall reach for the laughing gas. But out of interest, does my part finished explanation above make sense?
  20. Or St. Ives. Emmets wandering all over the place getting in the locals way. Can't make up my mind what is more annoying, a teenage girl saying "Oh My God" loudly into her phone or Greta.
  21. The initial butter temperature will make s difference. Oddly, I am sitting in the sun reading Randall Munroe's What If? Write to him and ask, Google xkcd for an email.
  22. Or @Ed Davies will explain it with radiation. Trouble is that it is not a controlled environment. Was it the same butter, was it the same dimensions, are there any drafts, sunshine hitting it. I buy Flora as I know it will spread straight from fridge, lasts weeks as well. Not do good for sauteed mushrooms, but then I don't have them at home much.
