  1. Yes no need for a battery but maybe some sort of current control other than heating up a resistor. How about nicking a super capacitor from a pimped up Corsa and having a relay running the pump only when the capacitor is at 12V. This way the motor isn't draining current below its stall speed.
  2. Yes but we would need to see the weight plate and with many diesel 4wd already failing the unladen weight bit...
  3. That may change with the recent outcry about plastics in the ocean as much of the smaller fibrils are from our washing machines. This last is a non sequitur; if you remove any element from the food chain the loss affects those further up, our wildlife biodiversity evolved because species inhabited every little habitat niche and had become dependent on that. Disruption can come from polluting rivers, controlling watercourses with weirs, pesticides removing insects or weed competition or simply reducing the size of meta populations with roads plus many others I haven't the imagination to consider. Consider population death happens way before the last individual death. With only 10% of England having been developed the vast bulk of the land remains under agriculture, so whilst I don't blame farmers I do believe farming practices lie at the heart of the problem.
  4. Tripus BR 01 seems to be available at 25 Euros plus carriage on their site
  5. I would have thought the increases in cancers diagnosed is mostly related to growing older, many people would previously succumbed to bacterial disease before cancers developed. We may well see a big return to that as the antibiotic age comes to an end and our naive population becomes exposed to what the third world has adapted to. Well there is little doubt my parent's generation were fitter in their late teens and early adulthood than mine, from my microcosm of the world so far they have also outlived us on current trends.. A reduced meat and dairy product diet with more high fibre food leads also to a more sustainable form of agriculture. As an aside an Indian bureaucrat I converse with , who worked for the FAO, estimates that if animals were not fed food that humans could eat the world could support a population of 12 billion,
  6. It's pole stage or post pole stage, one cannot walk through a thicket You're a tiny bit younger than I then Yes but fertiliser is either mined or very energy intensive, think why Norsk Hydro appears on nitrogenous fertilisers A stere says they were never addressed and as a result insect mass in Europe has dropped to 30% of what it was 30 years ago. People on here have even remarked on how clear headlights and windscreens remain now. Don't get me wrong, in a world where only 5% of the cereals grown are traded it seems unwise to depend on imports and given only 0.5ha or less of farmland for each person it seems daft to waste it for energy. Especially even with imported wood pellets biomass has never exceeded 3% of our energy wants whereas wind has contributed up to 30%
  7. I wonder how they define failure? Anyway it makes it look much more interesting and if you could use it to full capacity for ten years that means the cost could drop to 6000/48936.8=12.26p/kWh retrieved
  8. No that's why tippers are ubiquitous That sounds like a challenge, I've only done it with a smaller amount in a pug 504 pick up but will try to see if the boss lets me lay a tarp on the canter floor on the next job he's booked me for, May 24th.
  9. Yes managing the ventilation must be a major point and my small experiments at home seem to show natural ventilation in an enclosed part of the stack isn't likely to be optimal which is why I mentioned fans and monitoring humidity. Still I'm surprised that the book Acer mentions claims there is no benefit in the extra heat captured.
  10. That's an interesting interpretation, a PCV has a legal definition in the Road Traffic Act 1988 "(a) a large passenger-carrying vehicle, that is to say, a vehicle used for carrying passengers which is constructed or adapted to carry more than 16 passengers, or (b) a small passenger-carrying vehicle, that is to say, a vehicle used for carrying passengers for hire or reward which is constructed or adapted to carry more than 8 but not more than 16 passengers [F6and includes a combination of such a motor vehicle and trailer];" and The Road Vehicles (Construction and Use) Regulations 1986 say "passenger vehicle a vehicle constructed solely for the carriage of passengers and their effects." and I suspect tools and equipment are not passenger's effects. This hardly surprises me, I stepped in to administrate the vehicle fleet towards the end of my career because staff had "left" and management had allowed the baton to fall on the floor. At that stage we had been operating with no trailers registered on the O licence and had been without an operating centre for 4 years (all without my knowledge as I managed another part of the business). In the 7 years none of the 4 vehicles on the O licence was ever pulled, other than a driver using a cellphone while moving and the copper let him off, I was a passenger at the time. The one person charged with the offence of driving a combination without an O licence didn't require one and would have been covered on our restricted licence should he have done.
  11. Go to the government website again and put your cursor in the address bar, click it and select all the address, copy that and post it in this thread. Not me Gunga Din as I cannot find this exemption

    I'm a few years out of date but last did mine at Prima in Ewell. I always advise people not to undertake the training other than through the company that will sponsor you as the competency is worthless without a work provider.
  13. Which actually also doesn't answer the question. In fact we sometimes removed 3rd party trees if they were deemed a threat and no charge was made. It was usually only when undertaking specific work (in my case making clearance fro a new high voltage retun line). Sometimes guys would take out extras if an adjacent landowner requested for a small consideration. Yes and this is why I would consider all the possibilities of doing the work safely without involving NR directly. Where I worked we had a department that prepared all the documentation for a Safe System of Work, which included researching when any possessions would happen and access to the track could be available but this is long winded. In this case it looks like the line has no electrification by overhead or conductor rail. It is not clear how far the rail fence is behind the garden fence nor the distance from the running rail to the fence or tree. If the distance is greater than 3 metres then it is not on or near the line, If the branches overhang the NR fence then they do have an interest but a railway competent company with the proper precautions could undertake the work using their own Coss and in live running if the tree could be dismantled without impinging on NR land, by rigging perhaps. The stem would need to be lowered rather than felled.
  14. No just handy with Ctrl A, Ctrl C and Ctr V for the bits inside the quotes At my last job we had a youngster pulled for no O licence ,amongst other things, with a trailer behind a transit (we had one but I took the Ifor triaxle trailer to the nearest weighbridge to prove it weighed under 1020, it was 960kg) and I was refused a class 4 test on my LR110 and had to pay for a class 7, next time I argued and had to get a weight ticket for the LR101 to get the class 4 test (it was about 1800kg with fluids so easily within weight).
  15. In fact I meant to write 2 tons, which is 2040kg but the legislation is The Road Vehicles (Construction and Use) Regulations 1986 and in regulation 3 (2) " dual-purpose vehicle a vehicle constructed or adapted for the carriage both of passengers and of goods or burden of any description, being a vehicle of which the unladen weight does not exceed 2040 kg, and which either— (i) is so constructed or adapted that the driving power of the engine is, or by the appropriate use of the controls of the vehicle can be, transmitted to all the wheels of the vehicle; or (ii) satisfies the following conditions as to construction, namely— (a) the vehicle must be permanently fitted with a rigid roof, with or without a sliding panel; (b) the area of the vehicle to the rear of the driver's seat must— (i) be permanently fitted with at least one row of transverse seats (fixed or folding) for two or more passengers and those seats must be properly sprung or cushioned and provided with upholstered back-rests, attached either to the seats or to a side or the floor of the vehicle; and (ii) be lit on each side and at the rear by a window or windows of glass or other transparent material having an area or aggregate area of not less than 1850 square centimetres on each side and not less than 770 square centimetres at the rear; and (c) the distance between the rearmost part of the steering wheel and the back-rests of the row of transverse seats satisfying the requirements specified in head (i) of sub-paragraph (b) (or, if there is more than one such row of seats, the distance between the rearmost part of the steering wheel and the back-rests of the rearmost such row) must, when the seats are ready for use, be not less than one-third of the distance between the rearmost part of the steering wheel and the rearmost part of the floor of the vehicle." If it is 4wd (i) above applies and you need not satisfy (ii) and below
  16. I wore a wave for many years until my late friend got nicked for wearing a sheath knife into a shop, as the blade was 3.5" it stays in my bag now and I wear this gift from my granddaughter. It replaces a leatherman mini as it has a torch and a small cross head driver and the little knife stays sharper
  17. Yes but it must weigh less than 2 tonnes unladen to be a dual purpose vehicle. I think this exemption only applies to vehicles (not being agricultural tractors or machines) that run between land in the same ownership and not more than 6 miles is done on the road in a week. There is also an exemption for works trucks that only travel between land in the same ownership and road distance is 1.5km
  18. Yes I agree, because the trailer is under 1020kg it does not require an O licence. As you have B+E you can tow it. As the gross train weight may exceed 3.5 tonne when laden you may need a tachograph, you almost certainly need a tacho and CPC for carriage of goods.
  19. I'm 5'7" and 11 stone so similarly at the higher end but within the fit range. What I cannot understand is why the old "if you can pinch more than 2 inch isn't a better indicater of belly fat (I can) as it's belly fat that indicates a problem and I need to lose some. The other measure is waist to hip ratio.
  20. it's a good point, I was assuming he had a pre 97 test so had C1, if not you are right. RE the above I was getting confused by the reference to 5 tonne, Re reading the thread I'll revert to my first position. No O licence required as the towing vehicle is under 3500kg and the trailer less than 1024kg. Tacho necessary for deliveries but maybe not within 100km of base if only carrying tools and equipment for driver's job.
  21. I agree, no O licence needed but probably would need tachograph unless operating under an exemption.
  22. I think you are both right for now. It's difficult to get a handle on because it's like trying to compare apples and oranges, depending on taste you could make a case either way. If I were desperate to show some form of power self sufficiency I would just buy one. AFAICS the Tesla powerwall for domestic use is £6k and stores 13,4kWh to 100% depth of discharge. It's life to 80% capacity may be ten years except it may only have 500 full discharge cycles, at 50% discharge they reckon on 1500 cycles. In the first case that's total storage over lifetime of 6700kWh and in the second 10500kWh. ignoring interest on capital that's 60-90 pence per kWhr retrieved and says nothing about charge discharge and self discharge inefficiencies. In fact I believe they will do better life cycles but time will tell. The second youtube video answered a couple of other of my questions: it cannot currently run islanded and grid tied. With our domestic electric consumption f down with the advent of good LED lights, flat screens and monitors, microwave cooking and induction hobs plus the cost of electricity rising and the possibility of incentives for storing electricity things will change quite fast. On the offgrid front it may offer some more utility especially if coupled with sensible CHP. I do have a bit of experience here and I can see it offers the ability to offset capital cost of a generator sized for peak demand and using a more efficient smaller genset.
  23. I still prefer Janis's version, ah memories....
  24. The railway was developed with an act of parliament in most cases , so the duty to fence out on safety grounds will follow that.
