  1. I would love it come, but the price is going to be way higher than the public are willing to pay. At 33 kWh/kg, a kg of hydrogen needs to be around £3 at the point of domestic sale. Rather optimistic that is. They will close down as, like wave and tidal power, they are relying on government grants (know a couple of people in the marine energy field, they are in and out or work).
  2. Why has this not happened. Hydrogen was known about before natural gas, probably before town gas. Electricity has been around for 120 years, mainstream for the last 80. None of this is new technology/science. I have not seen anything on the horizon that can electrolyse, process, store and transfer hydrogen cheaper than electricity, or heating diesel for that matter.
  3. Really. Unless the oil industry, who are the experts at deep, directional, drilling convince the government of the day that there are unbound, deep, hydrogen reserves, right underneath finite, geological methane reserves, it isn't going to happen. Hydrogen is pretty poor energy carrier, and we would not be burning it anyway, it would pass though 'fool's ells".
  4. Using modern adhesives is generally quite easy, though often messy. My go to timber adhesive is now Lumberjack. It is a low expansion polyurethane, comes in a tube. Many people say that foaming PUs are the way to go on rough surfaces, and making the surfaces wet helps. I am not sold on this for structural usage. The more bubbling you get, the less adhesive there is holding it all together. So while many modern PU adhesives say they use moisture to aid curing, I suspect that it also reduces shear and peeling strength. Rough cut timber may need to have the worse of the splinters removes, and be made dust free. Washing with water is ok for this, but allow an hour or two for drying, you don't want it dripping wet. The most important thing is the clamping together of the two parts. Don't be tempted to just clamp at ends and middle. Even low expansion foam adhesive can exert a lot of pressure. So lots of G-Clamps and some sturdy 50mm by 75mm (or deeper) thick timber to spread the loads (note plural, PUs expand, then contract). Don't be tempted to take the clamps off before fully cured. If you are worried, try it out on some test pieces. You will learn so much about using adhesive.
  5. Are you thinking of having gas central heating? Or wondering about resale? Really comes down to the financial numbers.
  6. Someone I know (not a friend).
  7. "We are making alot of power off the roof yesterday 551kw Today with this as part 1267kw so far since 3pm yesterday. At the moment we are using the power for flat no import as waiting documents for power company. Felt strange using washer without cost to us."
  8. Just a quick observation about MVHR and opening windows. MVHR is ventilation, opening windows in the summer is climate control. Not the same thing. No one thinks that you need to turn your MVHR on, or off, when you turn your heating on in the winter.
  9. Gets the nail varnish off as well.
  10. Have you tried the three easy to get hold of solvents? Acetone White Spirit Methylated Spirit
  11. Why do you want Velux, is it room in roof? Have a word with @craig, he is the go to man about glazing.

  13. You gave to put that assumption on a CO2/Environmental basis. Everything we do will have an environmental impact somewhere, just that some damage is very visible i.e. slash and burn agricultural policies, and others are not i.e. the slow rise in global temperatures. Generally, product miles are tiny part of the problem.
  14. https://chem.libretexts.org/Bookshelves/Introductory_Chemistry/Introductory_Chemistry_(CK-12)/23%3A_Electrochemistry/23.01%3A_Direct_Redox_Reactions Best to keep copper and zinc separate.
  15. How different are the building regs and warrant stuff in Scotland, compared to England?
  16. Welcome. Where in Dorset, used to live there, and spent my youth at university there, but then it was just a HE college.
  17. We have propane at work. 9 kW burners, though I have a feeling that gets delayed when running on bottles (similar to chefs). I find gas brilliant for heating up pan handles. H&S says to turn the handle away from the front of the range, so I swivel it around 180°, right over the back burner that has been left alight. Old jokes are the best. I do find in a commercial kitchen, gas very wasteful, once lit, it stays lit till close.
  18. I have never said that. My recommendation is always the cheapest fan heater.
  19. Most charge, you must be desperate to get views.
  20. Right, I had a brainstorm. My original spreadsheet to look at the effects of ventilation strategies was too complicated. So I have reduced it to the basic minimums of natural ventilation (the holes your builder leaves you with) and mechanical ventilation (what you choose). The only things you really have to find out is the total treated (heated) volume of your building, the number of air changes (both natural and forced), the mean, local, air temperature (Met Office is useful here), how warm you like your house, some information about the MVHR efficiency, never trust the manufactures numbers, be sensible about it and that is about it. I have only just knocked this up, so there may be errors, but you can see the formula, and edit them if you unlock the sheet. Hope it helps. ACH and OAT Thermal Losses (excel).xlsx
  21. Yes, I saw that as well. How are they going to view all our security cameras when they have cut all our power.
  22. There is this on the gov.uk site. https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://infrastructure.planninginspectorate.gov.uk/wp-content/ipc/uploads/projects/TR050006/TR050006-000310-Doc%205.2%20-%20ES%20Desc%20and%20Alts%20App%202.1%20-%20CEMP.pdf&ved=2ahUKEwie8cPv0KqNAxXBVUEAHUBHAssQFnoECH0QAQ&usg=AOvVaw0kotOFx7na0J8i86kpiEgY
  23. In the old days, we just chained bikes to downpipes. Occasionally, it was my own bike.
