  1. Mousehole is hardly urban.
  2. And lots of mopping up.
  3. £100 buys a 1.2 kWh leisure battery. £20 an inverter and about the same for a mains charger. What is the aim here?
  4. Mousehole in Cornwall. 2700 miles of nothing to the west. Then this. This only shows 4, but counted 7 so far. At least these ones are visible.
  5. Depends on the pressure. The SHC is better than sand at 1kJ/kg.K. A m³ at sea level has a density of about 1.2 kg/m². Double the pressure, halve the volume.
  6. I am sure I would quite like heroin, not sure I should try it, I have seen what it has done to my neighbour.
  7. Lots of Thermos flasks. Aerogel is 0.013 W/m.K
  8. You could compress air, which will warm up with entropy and then add in extra energy with an element. Then release it back.
  9. Wish I was. I have so much advice for 40 year olds. Seems strange that when I was 40 I was lecturing undergraduates, no idea what has happened to them, except 1. But most will be getting close to 40 now.
  10. 1 kWh. How are you going to insulate at those temperatures? How are you going to get the energy back out?
  11. Yes, but I now know that a stuffed toy can flick a switch with cat like reactions.
  12. So basically there are two circuits, one increases the mains frequency (50Hz) to the resonant frequency (400Hz maybe). This produces a fixed power output. The other circuit switched that resonance circuit on and off. This then pulses the pan with energy. More time off than on, the lower the temperature, more time on than off, the higher the temperature. Yes?
  13. I have a 1987 TF place, no problems. Just get a proper survey done.
  14. Looks like English but can't make sense of it. Does it basically just turn it on and off to limit the power, or is the power limited by reducing the current input to thee induction coil?
  15. Or becomes new soil. There is a perpetual myth that any fallen timber rots down to CO2. Probably why the CO2 levels in the Amazon rain forest are chokingly high. Good job that all the ocean flora is collected up and stored safely before burning, would have to swim in carbonic acid otherwise.
  16. Does that stop the pollution and habitat destruction? If I grow my own tobacco, will it be acceptable to smoke it in a pub?
  17. Same as we did in the UK 50 years ago, wait till the power comes back on. In Paris, if something is broken, it is usual to riot. Get a gun. Just don't breath in the cordite fumes. The WHO has declared that there is no safe limit for particulates. https://www.who.int/teams/environment-climate-change-and-health/air-quality-and-health/health-impacts/types-of-pollutants This does not mean that we are all not breathing them in all the time, but adding to them is not a good idea.
  18. Most of my jokes are recycled.
  19. My induction hob pulses, like the old resistance hobs. I think they all work like this.
  20. Basically because there is a cost in producing a lower energy fridge, it may not seem much to us to put in a bit more insulation and change the compressor type to work with a different pressure refrigerant gas, but to the companies that have to to develop, engineer, produce, market, distribute and warrantee them, that cost is millions. To raise that investment, they have to have something to sell, and that is the older, proven designs. That is how mature businesses work.
  21. Sounds very good to me. When some wind farms were build in Australia, many residents complained about the noise. When the developers showed Thier operational data, a lot of the time the turbines were shut down. Transpired that farms in that area were virtually worthless and the owners were trying to get compensation. So log noise data as well as operational data, then see if it correlates with the times the neighbours say it disturbs them. You could actually tell them this is what you are doing, then they will know to take you seriously.
  22. Yes, but you would have to glue a spare phone to the meter. My monitor just needs a small washer glued over the LED, and it logs a timestamp every time the light pulses.
  23. Fridge/freezer energy performance was a rolling scale, so what was lowest 4 years ago drops of the scale and is replaced by what was middling, the best rating got even better. So todays Es and Fs are better than 4 years ago B and Cs.
  24. You could count the LED pulsing and use that data.
