    Sad, but my Ferguson Te20 had to go to pay for the boat.

    Got that thanks.

    I have a need for a low frequency, and fairly loud horn, electric powered, 12Volt. Any suggestions gratefully received.

    Employed some years ago using industrial components, the following was employed for an all-electric boat: Diesel generator 22kVA, acoustic enclosure, 230 Volt 3 phase, delta, operating at constant speed, keel cooling and enclosure exhaust provide the necessary heat dump. Inverter drive 18.5 kW, 230 Volt, 3 phase, speed control and direction via a small throttle lever. Motor, 6 pole, 3phase delta connected. Prop shaft coupling through flexi coupling, no gearbox required, providing a stepless speed range from zero to 1000rpm or greater. Surplus power available for cooking, washing machine, dryer, microwave, and ancillary loads. To bring this system to date for a ‘hybrid’ solution, would require batteries connected to the inverter drive, providing a Voltage operating ‘window’ of 180 to 260 Volts, qty 22 lithium ion cells, at some cost, with a suitable 3 phase charging system. The operating window between batteries and the inverter drive could be optimized with a DC/ DC system. A system of solar power would complete the package, to include a robust shore supply. The lower operating voltage would provide a system without the hazard of having 400 volts 3 phase, and all galley components would be standard domestic. Whilst deviating from the original question, this provided a working system which may help in principal, with anyone planning a diesel electric boat.
  5. A few canal boats plying the waterways supporting a past heritage going 'Electric', it is a worthy exercise; but is this not 'naval gazing', when considering the need to reduce the real emissions from road transport, agriculture, and marine? It cannot be beyond the wit of man to introduce a small amount of perspective into this situation. For the population of the canal system to roll over and accept legislation, which will potentially remove these traditional ways, turning this heritage into a Disney theme park, cannot be acceptable, spotted red neckerchiefs and flat caps all round?
  6. For these changes to take place, the national grid network must be turned inside out. Currently power stations and generators are working at the ‘thick end’ of the supply network, transmitting power to the outlying regions, copper getting thinner as it reaches the consumer; now this is being reversed as the generators range from solar installations in fields and on houses, to remote wind farms far out to sea and the tops of Welsh mountains. Transmission line potential of 800,000, 000 Volts is being planned is required and will be implemented as the surge for renewal systems progresses. Down at street level, 400Volts 3 phase will be distributed, but to use this for battery charging the conversion to DC on board will be full of losses both harmonic and resistive. When electrical power is transformed and manipulated losses are incurred, the bit which is conveniently neglected in the proposals for this new life, losses which bring us back to parity. Throughout the plan is possible, ‘we have the technology’, but the understanding of the complexity and costs, I believe is well beyond the policy makers capacity for understanding. The transition to Diesel, will be the most recent example. At the time ‘lean burn’ research for petrol propulsion with extremely low emissions was abandoned for the Diesel option, this was very recent history we all rember; and here the ‘knee jerk’, political box ticking is played out. Yes, we need the poor unfortunates, but controlling their impulses with our cash, building bollards down the canal bank should be reserved for another day, a long way off.
  7. I guess it would be to much to ask, what is the nature of the ‘refurbishment’? And who was the elderly gentleman in a ‘hoodie’?
  8. The machine load appears to be 1600 Watts, which will be including the heater. Too high for the Victron I guess.

  10. A good read http://www.hpcdfuel.com/pdf/DOWfuel_training.pdf
  11. The US is awash with firms competing for funding for this stuff, based upon flimsy evidence, and marketing hype, for duration, safety, and speed. I will wait a long time before I get to 38 thousand feet, in a hydrogen powered bomb, as will my pension.

  13. ‘Naval’ gazing to be sure………. Inland canal traffic, does this have a significant effect upon UK emissions, compared with road, aircraft, large marine systems, and farting cattle? The efficiency of power plants like nuclear, and natural gas turbine, here used for prime generation and extensively for backup support. These technologies are based on a thermodynamic cycle, which efficiency is in the order of 35%. This massive balance being wasted to atmosphere if it cannot be captured. Losses due to wind power, and solar are greatly reduced as the thermal cycle is not involved. The overall losses between the power plant and consumers is then in the range between 8 and 15%, even for these renewable systems. Losses occurred during each transformation through the grid network and transmission lines, again generating heat. The prospect of installing power distribution canal side, further increasing the transmission losses; the taps for potable water are demonstrably poor, and have been for years, what hope can there be for copper wires buried in the towpath? If CaRT get wind of this little scheme we are all ‘doomed’, the ‘marketing’ department will have a political field day, electric bike charging becomes a possibility. The storage of electrical energy has a long way to go yet, transporting a ton of leaky storage, under the bed with the potential to produce millions of Volt Amperes of fault current, fails to convince me yet; that this is an efficient process. The nature of canal boat electrical systems being ‘bespoke’ at best. Diesel may get a bit murky over time but relatively inert and safe to store. Also, are we not responsible for preserving the tradition, not my Kubota I am thinking, but the ‘donk donk’ of the traditional power plant is part of the life, and the living heritage. We are aware this is driven by people, decision makers, young hearty people, who are dimly aware of their surroundings; and to have a rudimentary knowledge of this heritage would be a stretch to far. The proposed dates, ‘By 2050 No non-zero emission boats can be used in UK waters (coastal or inland)’ are fanciful in the extreme. And what is the point, have we not bigger things to be occupied with? Dredging, repairs, reservoir supplies, lock gates, sluices, ground paddles, the heart of the system, and not failing to repeat a mantra ‘This Heritage’.
  14. Thanks for all the replies and help here. My mistake was to get into conversation, which was to complain about an overcharge for data. The data should have had a 'cap', and 3 agreed that it was their fault that this was not applied, subsequently my bill this month was five times my normal monthly charge; to this 3 affirmed that they would not reimburse me? The emotional pressure was rising at this stage, and further conversation with 'customer services', quickly became ridiculous. I have now found the link to terminate this account, and apparently after 2 days this will be done?? Great relief if this works, and once again thanks for all the suggestions and advice regarding this murky world of mobile phone operations. Thank you, Canal World.
  15. Thanks for that, I have an O2 account best option I guess. Thanks
