  1. So do you think that is what really happens. If you had a fixed structure size, and a fixed window area, with the only thing changing is the mass of the building, then temperatures would be significantly different for varying weather conditions and climate regimes?
  2. Too large to maintain temperature stability. Good question, look forward to the answers
  3. That would be "that is it", rather than "Coke is it" then.
  4. And there is the odd quirt that C is used for coulomb (named after Charles-Augustin de Coulomb) and is an amp.second, or just to make matter even worse, a farad.volt if talking about capacitors. The sign for farad (named after Michael Faraday) is F, just to confuse with the Fahrenheit scale. Thank goodness for the ° sign (which is Alt + 248, or Alt + 0176 on a PC). Now who wants to explain ' and " with regards to time, distance and angles. And Prime Numbers, or should that be primes.
  5. I suspect that the majority of TFs in England is the volume builders. Most small developers probably stick with block.
  6. I made a bi stable and multi vibrator, with a couple of trans. Things were different in the 80's.
  7. Not all, now I have to put up with millennium snowflake parents with their overly cherished offspring. There is nowhere left to be a free minded adult anymore.
  8. They are cheap, under 3 quid. And it does give you the opportunity to do other things as well. Complication is a complex thing. My car is complicated, as are the roads, and the associated rules to use them. But they get me to the seaside and back, and I can't even now, 15 minutes after the journeys end, remember anything about it.
  9. I think most of the 'cons' go back the Barrett Homes fiasco of the late 1980's, more than 30 years ago now. Anything that is designed and built badly is going to have problems. It does seem that brick and block is a really English thing, most of the world uses poured concrete or timber. A friend of mine, who is unfortunately American, worked for a large Architectural company, when I said the old saying 'as safe as bricks and mortar', she did not know what it meant. Or the windows are too large.
  10. https://en.wikipedia.org/wiki/ESP8266 @TerryE is the man for these.
  11. Just reading the longer piece about it. I hate legal language, but it is quite interesting about the 'material and weight' aspect. The real answer is to develope more, low density, housing. If your neighbour is 200 metres away, it would be a rare event.
  12. Add kW and kWh to your autocorrect.
  13. Just had a quick scan of the article. A similar case happened in the US about a decade ago. But the picture amazed me, how does that produce 11 kW as claimed by the article. Maybe there is more hidden away on the other walls and under the shed.
  14. Yes it is.
  15. Why is the RPi not counting the pules off the meter?
  16. We should just measure all energy in the derived SI unit of joules (or kJ, MJ, GJ, EJ). Would make life so easy to compare then. Seems barmy to me that we sell bottled gas by the kg, liquid fuels by the litre, coal by the sack, timber by whatever someone want so to quite (bag, tonne, cubic foot, lorry load). No wonder people are confused. We can label food with kJ, why not the rest of the energy market. And don't get me started on BOE, Therms and what Americans use.
  17. I am in split minds about that. I am not sure of the figures now, as it is 40 years since I studies automotive engineering, but back then, a secondary brake (hand brake) had to be capable of applying 14% of the vehicles rated braking force (that depends on age and mass of vehicle). Applying all 4 brakes via the foot peddle, supplies up to 100%. There is also the matter of brake cooling. Depending on the type and style of driving, applying a brake onto a drum or disk can cause either overheating or reduced cooling. Not so much of a problem these days as brakes are very good (mine have done about 100,000 miles without any maintenance/replacement), but other drivers may not drive like my Mother and overuse brakes.
  18. Ah, right. It was not too clear from the data sheet. Can I connect via that to my raspberry pi.
  19. So if banks/lenders will not lend against a property with the correct and acceptable insurance, the site should be worth the value of the land, minus demotion and disposal. Bet if you asked a lender to sell you a place at they they would say bugger off.
  20. Is there enough kVAs? shows 4kV, which is 17.39A @230V but only 16A @250V. But I have no idea what size your system is. Has a max wire size of 2.5mm2 on the output, so that may be a problem too.
  21. Buildhub doesn't to as well as expected. https://www.scamdoc.com/view/71796
  22. Electric Drill and Angle Grinder. Do just about everything with those two.
  23. Why I am questioning the pipe spacing, seems a bit counter intuitive to me. But it may depend on the depth of the pipe and the temperature of the fluid.
  24. Could you explain the reason for that?
  25. Already happened, how else can you explain building on flood plains, next to beaches and halfway up muddy hillsides.
