  1. They have never been to France then.
  2. Which is why it hurts when good advice is totally ignored.
  3. Those children know why you need to get a thermometer, which temperatures to take, why you need to take them and how that can help. But this child is just going to be childish, except I am no ones child any more.
  4. Would it need to be under a steel plate as well, or is that for <50mm.
  5. I seem to remember that the plug in wind turbines were 1kW nameplated. While they would very really generate half that, the rules may allow for 1kW to be fitted already. I suspect it will not be the most cost effective method for home generation. A lot of people will buy them but place the panels badly and be very disappointed. That will lead to a lot of bad press and set back domestic PV installations.
  6. It just goes to the nearest load, wherever that may be. There will be safety features built in to auto disconnect if needed. We had plug in wind turbines 20 years ago. They literally had a 3 pin plug that you just pushed into the wall socket.
  7. That may be on the DC side, but then there will be a bit of induction on the 230 VAC side. Jury rig something up and test it. A capacitor, resistor and/or a diode across the lightweight AC switch may help (snubber).
  8. The problems here are manyfold. So no easy answer. What is probably needed is a very flexible coating that is water and UV resistant, vapour permeable, easy to apply (spray), cheap, the right colour, and because you are in Scotland, temperature stable. Search for microporous rubberised coatings. We used to use a Jotun product if a sauna was next to a steamroom or spa bath.
  9. Look up the k-values. Mortar around 1 and dense plaster about 0.6.
  10. High resistance R-value. Low losses are U-value.
  11. Enough to run a couple of RPis for data logging and web serving. Any turbine below 5 kW is pretty pointless in my opinion. Much better to get everyone that wants a turbine to put the money towards a 5 MW one and pocket the revenue cash.
  12. Did they not sell them on the Bounelli effect that a restriction increases airspeed. Never seen any mention of reduced density because of lower pressure, but then marketing and PR would be horribly dull if a real or imaginary, number was put in. I once went to a talk about solar power, the lady delivering it put up Einstein's E=mc² and explained that as the mass, m, was very small, we could ignore it. Did not take long for the hall to erupt into laughter.
  13. You are going to need something the region of 0.6 kWh/m² to exceed 27°C floor temperature. So if your power input is a ridiculously high 100W/m² going to take a 6 hours (this assumes 7°C above ambient). You can probably just change the flow temperature curve to limit the floor temperature overshoot.
  14. There is a lot of Talk about climate change. One word saves a lot of hand waving.
  15. The problem with a 'plasterboard tent' is not just the extra heating cost, it can cause damage to the frame because of uncontrolled condensation. So while it may technically pass the air test, it is still faulty.
  16. What happened to our old forum member @Construction Channel
  17. I worked for a small turbine manufacture almost 20 years ago, even then a 4 or 5 kW turbine would have been close to £20k. They have never been cheap. PV was a similar price back then.
  18. "Greenest Government ever" Followed by "Get rid of all this green bollox" As we are into the third week of this oil crisis (I have been though a few), we cannot be far off what it would have cost us to have tripled our wind and solar capacity and kept the subsidies on BEVs. https://www.theccc.org.uk/2026/03/11/cost-of-net-zero-by-2050-less-than-a-single-fossil-fuel-price-shock-ccc/
  19. If you are going to have any pictures hanging on the walls, you can line the back of the them with carpet, quite effective. Alternatively, you could experiment with a 'sonic crystal'. Lot of playing about to find the correct length, diameter, density and orientation, but can make for an interesting bit of art in the room.
  20. Different vapour permeability, it may be important.
  21. Can model all that with a 3 Parameter Weibull Function.
  22. I can testify to how hard a Cornish Hedge is, totally unscathed after a glancing blow at 60 MPH.
  23. Going to be equinox in about 50 minutes, more time to generate PV.
