  1. That's right. Couple more points I remember, electrolysis produces hydrogen and oxygen from water, but at the plant the oxygen was simply discharged to the atmosphere, wasted. Also, even without any form of fuel duty and after all the government subsidy the actual fuel cost per mile is significantly higher than petrol or Diesel. And the car costs three times as much in the first place.
  2. Couple of points I picked up on a recent tour of a local hydrogen plant. (1) It's seriously inefficient. They quoted an expectation of reaching 65% efficiency some time in the future, I can't remember what that was conditional on. Maybe running 24/7. You can see all the losses when you see all the plant running, multistage compressors, pumps etc, and a huge cooling plant disposing of the heat generated by compressing to however many hundred bar. (2) The "using excess renewable energy" story is pure fairy tale at the moment. The plant takes hours to get started up so they typically run for 8 or 10 hours. The energy uses is therefore whatever mix is on the grid at that time whether that's renewable, nuclear or pure fossil fuelled.
  3. Most comes from our own trees, but if we have to top up it's £45 per cu m collected, for dried split softwood 250mm lengths. £85 for hardwood. https://www.firewoodbylfs.co.uk/linnorie-firewood-products
  4. Around £25 from Garden Hire Spares.
  5. How often is air or vacuum leak the culprit?
  6. If I'd looked properly at the pictures I'd have seen differences in the fuel pipe - particularly that the corrugations don't extend right to the end. Maybe not so apparent that it's a bit longer either. However without hindsight I might not have guessed that these would make the hose kink and flatten at the carb inlet and therefore completely useless.
  7. Hi, I was wondering, in general, which parts if any people would be happy replacing with third party, and which you'd say definitely stick with genuine Stihl. Also any recommended suppliers. Last time I bought bits I used an Ebay seller by the name of blindstickinsect, also trading as "Mister Solutions" but the seem to have disappeared. I'm writing this after trying a third party fuel pipe, and finding it completely useless. I don't know if I was unlucky with the supplier or whether it was just a bad idea in the first place. On the other hand the impulse hose and the oil pipe on my MS180 both seem perfectly fine. Thanks, Tony S
  8. Is this the two saws on Ebay, "unwanted gift"?
  9. We've just had some cutting done by SSE, well actually by a tree company contracted by them. I think the issue is that they only want to come round every four years or so, so they're going to cut everything back so it won't need attention for four years. Regarding cutting yourself, that depends how close to the wires it's ground. SSE wouldn't want us to cut anything that's within 3m, whereas they are allowed to cut if it's over 0.8m. So for me to cut it myself I need get in a lot earlier.
  10. I think your local Planning Dept should be able to tell you how the land is currently classified, for example in the past there may have been a Change of Use planning permission to change from agricultural land to garden ground.
  11. Shouldn't kiln dried wood be dry right the way through?
  12. I've seen a lot of reference to that 38% figure "38% of UK primary PM emissions come from burning wood and coal in domestic open fires and solid fuel stoves" but I don't think I've ever seen that broken down between wood and coal or stove vs open fires.
  13. Our old McCulloch brush cutter gave three permissible fuel mixes .. (1) McCulloch synthetic oil at 40:1, (2) Other brand synthetic oil and lead free petrol at 40:1, (3) Anything else, 20:1. Not sure what to make of that but it suggests that leaded petrol didn't in fact help with lubrication.
  14. I sweep mine from the top with normal rods and a brush. The debris ends up in the stove and can be removed once the dust settles. None of my house insurers have ever had anything to say about stoves, chimneys or sweeping.
  15. Fair point. I was just going by what was posted earlier, I don't read Norwegian except via Google. Why don't you have a look and see if they have the same advice in Norwegian or other languages?
