  1. Scuba divers spit into their masks, finger it around, then rinse off. It works but I have no idea why. Do my shiny acrylic replacement lenses that were put in as replacements for my old cataracted ones count as safety lenses. Driving is safer now.
  2. Is it covered in this: https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/518193/Guidance_on_Firearms_Licensing_Law_April_2016_v20.pdf Personally I would just make them all legal. If you want to catch squirrels, a trap is probably better.
  3. The radiator manufacture should have a data sheet on what the power output is for different temperatures. Good place to start.
  4. Not unusual for a development company to rapidly increases sales just before a sell off. It is how venture capitalists make money.
  5. There is a reason that shipping containers are not used to make many houses. Foundations is not one of them.
  6. Not as simple as that. Generally a heat pump works at a lower temperature than an ordinary boiler. That is why the radiators have a larger surface area. If the installation was gas or oil and the radiators were sized correctly, then new ones, with a larger area, would still be needed.
  7. Doubling the breadth does not make much difference. But probably be enough for your needs. Calculate it if in doubt. https://www.engineeringtoolbox.com/beams-fixed-both-ends-support-loads-deflection-d_809.html
  8. My local library used to get in any of the standards I wanted when I was researching. Not sure if they still do. May be worth asking there. They used to charge for photocopying, but at a reduced rate as I was a student. They never checked I was a student. I was in my 40s at the time.
  9. Plastics have been recycled for decades. We used to have large containers outside the factory for the vac formed off cuts and scrap. Prices varied by the type and colour, but it was always worth doing, and that was nearly 40 years ago. Really need a bit more information.
  10. Judging by your picture, it looked like you bathed in it. Are you auditioning for a part in Chernobyl.
  11. Quite the opposite, I did my BSc final year project in solar thermal. Since then, the world has moved on and in my opinion, PV is the way forward for domestic use.
  12. Post them up for us, just like the EDXCEL exams.
  13. followed by 10 lines of text about how complicated it is. It is not just control systems, there are accumulators, pressure valves, safety cutouts, replacing fluids. When a car boils over, you can just fill it with some water, but you really need to fill it with anti-freeze as well, and find out why it has overheated, which could be, in no particular order: broken hose faulty waterpump faulty thermostat internally blocked radiator externally blocked radiator failed head gasket broken fan broken fan motor broken fan belt and a few more things. The above are some of the reasons I think PV is a lot simpler and reliable.
  14. @Ed Davies using FF 67.0.2 the lastest update as of this afternoon. Brave is based on Chromium and has an opt-in for their advertising system. I have not opted in. The main problem with Brave is that it is not a true portable app. Passwords are stored on PC. One thing I like about it is that it has TOR built in (just click on the user icon and pick from list).
  15. This is just a quick, one sample, snapshot of a problem with Firefox Browser. This has come about from a conversation with @Ed Davies on Zoots topic about a slow computer. I have the latest version of FF and it is still memory hungry. The screenshot is of Task Manger showing memory usage. Brave has been open for an hour or so and has the forum loaded. FF is just opened up with nothing loaded.
  16. That name rings a bell. They had one at the university I taught at.. It was meant to be for testing and training. Just after they got it, the company went pop, so no idea if it is still about. I liked the simplicity of the system as it was basically a panel and a pump, differential temperature controller and a pressure relieve valve.
  17. If using ET on a drainback system, is there not a problem with the longevity of the ETs. The only Drainback system I have seen up close is the one that had an acrylic cover (it was formed into 3 large 'bubbles'). I think the company that made them went bankrupt a few years back (about the time FiTs started).
  18. I go along with that. One of the problems that all trades suffer from is jargon. Something to just stop that would be a good move, then people can start talking a common language.
  19. Someone, over at the other place, designed a simple system that was, on the face of it, under tubed (may have been flat panels). His thinking was that by eliminating all risk of boiling, the control system was simple and reliable. I seem to remember that worked well at scavenging to raise the base temperature up. I can't remember what he did for the final temperature boost though. Probably electric immersion. They are always good.
  20. We used to put our sheets of plastic in a large, low temperature oven before vac forming. This drove off any moisture and made the process easy. The most sensitive plastic was polycarbonate, that took days in the oven. I can't remember what ABS was like as we usually injection moulded that, but the pellets still got dried beforehand.
  21. Probably best not to call your BC Officer fat.
  22. Is it one of those jobs that is a pain in the arse, but relatively easy, or one that is a PITA and difficult. I would think the second as you have to make sure that you do not damage anymore pipe and then the cleanup of said pipe has to be done well. Would it be possible to mark up the floor with a felt tip pen where the pipes are. If you use a good one, nice and fat and inky, it should still be visible after after any tiling has been removed. No good if it is a polished concrete floor.
  23. What can be done to repair a pipe once it is drilled though. Or how easy is it to repair a broken UFH pipe.
  24. Just a couple of weeks to go. Then I can write it up in the best undergraduate fashion i.e. late at night and quickly.
  25. Pick the nearest station. https://www.metoffice.gov.uk/public/weather/climate-historic/#?tab=climateHistoric Local rainfall and flooding are not always directly connected. You have to take into account the local topology and rain catchment area. Then look at all the measures that have been taken to mitigate it. And that is as well as looking at local geology.
