  1. the first computer i had at home was a dragon 32 32k of processor, then at work we had unix cad workstations, these were far better than the windows machines, but our file server was at head office at the other end of a 52k data line.
  2. For the old boat number it may be written under the drawers.
  3. There is already a requirement for kerbside charging points (or electric charge parking bays) on most new developments as well as masses of bicycle storage for developments in london, the problem is that each full spec vehicle charging station is the equivalent consumption to about 10 homes (a standard 2 bay charging pillar uses 16 kVA whereas a house averages at 1.5kVA) - the reason for this is while a house is rarely using everything at once, a charging point is either on or off, so diversity cannot be applied - it has to be assumed that overnight the charging point will have cars plugged in and charging, diversity is a calculation whereby the average use is spread across all of the houses and then divided out, rarely are everyone using everything all at the same time, years of comparative readings have averaged out the average 3 bed house at 1.5 kVA a 4 bed house at 1.8kVA (for gas heated houses), as appliances are turned off and on through the day and night and this is factored into the substation loadings, car chargers are a fixed usage when on so have to be factored as on all the time when calculating the substation loading. so for every charging point 10 less houses can be supplied from any given substation. if you have an existing substation at full capacity for the number of houses, you would need to build at least 5 more to supply the charging points for every house to have access to one. (remember a charging point can charge 2 cars)
  4. the type of connector should make no difference, just ensure the bolts are tightened properly as a loose connection is a source of heat and can deteriate to the point of failure (fire)
  5. In reality they know we cant just switch over to hydrogen until the gas network has been converted over, also the technology for hydrogen engines is still in its infancy, so work still needs doing to get there, in the mean time they are trying for a halfway stage of electric propulsion but using batteries rather than fuel cells, unfortunately this leaves the problem of charging the batteries, which we dont really have the infrastructur for yet. its a catch 22 - without the charging facilities people wont buy electric vehicles, but until people buy the vehicles companies and councils are wary of spending large amounts of money to install charging points when they dont see the number of cars on the road to warrent the infrastructure.
  6. at our current rates you wouldnt be looking at change from £6000 for a 130m cable direct buried at the correct industry standard depth in turf, the biggest proportion of the cost being the trench. as for electric propulsion, this is just a stop gap measure before converting vehicles to hydrogen gas as a fuel, once the natural gas network is converted over to hydrogen, then there will be a plentiful supply of hydrogen to power vehicles, and it can be filled up in a similar manner to petrol or diesel, by a nozzle from a pump (ok a foolproof gas seal for the connector will be required) which will then either supply a hydrogen fuel cell for electric propulsion, or a conventional engine using the fuel directly.
  7. yes I too had the bad gateway errors on sunday, probably the hosts doing server maintenance as it was timed in the middle of the night for the usa. we did do a forum update yesterday morning (or was it Monday) so maybe refreshing the page (ctrl + f5) would help clear any errors, though any updates should clear through your browsers cache over the next few days anyway.
  8. my daily commute is above the limit of the majority of electric vehicles, and that assumes that I can charge at work as well as at home, neither of which are viable at present, we do have a pair of charging points locally (about half a mile from the house) but charging from my house is not possible as the road runs at right angles to the row of houses, plus the electrical infrastructure is at maximum loading already. every road would have to be dug up to replace the cabling for greater loading.
  9. well at the age of 75, i might just stop driving at that point, or just keep driving my (by then) ancient volvo, i do note this is only the sale of new vehicles, so with some broads cruisers now nearing 50 years old, that seems to leave them good to outlast the ban until 2085 or longer (i know there are older cruisers around, but most will have been re-engined.)
  10. just one thought intrudes here, if the council had done their duty of care investigations into the legality of the signage, then how come they were erected before they consulted the secretary of state (or department of transport), so as such that belies your statement above as they would indeed appear to have chucked the signs up before full consultation.
  11. I was lucky as I lived so close to my secondary school, i went home for dinners. we were also lucky in as much as we were on the direct high voltage feed from the main substation to the hospital, so we lost power a lot less frequently than most, and usually at convenient times for the hospital.
  12. at my primary school you sat there until you had eaten it, I was once forced to eat fish which I am allergic to, I protested I was allergic, my sister protested I was allergic, i was still forced to eat it upon which I promptly threw up all over the canteen floor, they never forced me to eat fish again after that.
  13. In situations such as described above my company restrict the applications to internal applicants only, where there is an advancement post available and we have staff who are qualified, this restricts the interview pool to the people in the company who want to shift roles around or advance up to the next stage. we are always seeking to recruit design engineers as there seems to be a general shortage of these everywhere, so we are happy to recruit graduates and then train them up through the ranks, since I joined the company one of the designers who was already here when I started has progressed up through senior designer and is now the design manager, quite a step up in just 6 years
  14. unfortunately its a good likeness of the real Griff, and there is no sofa to hide behind aboard Broad Ambition
  15. the gas heater above the bath, that was condemned as soon as the first gas man came to fix it. ice on the windows in winter - inside. the paraffin stove that caught fire when it got knocked over heating the kitchen in winter helping with the washing up getting the washing in off the line where it had frozen solid. getting bronchitis every winter and missing a month of school recovering
  16. Nice starter, what did you have for breakfast?
  17. Now down in Kent there were dedicated cycle paths way back then, they were there to allow the miners to cycle to the collieries from the local towns below shown the cycle path from deal to Snowdon Colliery from 1960, you can see the road, cycle path then footpath, though they dont appear in the 1940 aerial shots, they do show the cycle path follows the line of the 1940 road.
  18. i remember when information travelled at the speed of the postal service, and drawings took a week to do, nowadays I can knock out drawings in a matter of a few hours, and in a week knock out the production of an office of about 20 draughtsmen working at the drawing board.
  19. the days when model making was a popular hobby amongst kids, when toys didnt all have batteries and we used our imaginations
  20. Not yet, but here is the figure, it stands on a block as model #1 has the cockpit floor lower, this models floor is much better placed for height.
  21. but a couple of stringers are wonky, and it leans to one side slightly and.... there is no harsher critic than myself in these matters
  22. final installment for the weekend, the first seat is done, to be honest i am sure the next one will be better, as i was just learning on this one.
  23. so joining up has started, drilling 2.5mm holes in 4mm legs is not easy, and i could only go in a mm or so to provide a pocket for the stringers
