  1. I don’t know how long a formula 1 battery lasts but you can bet it’s not measured in years. But the point I was trying to illustrate was that lithium batteries are significantly different to lead acid and can accept a much higher rates of charge. Most things in F1 are pushed to breaking point but they can’t afford things to fail so that’s where the super caps kick in, protecting the battery from sudden high current demands. F1 is a virtual testing ground for our future cars. Bill
  2. Apparently there was also a rush on baked beans so that might explain the toilet paper Bill
  3. I’m not too sure about that Davey but a normal lead acid battery and lithium based one are two very different technologies. I know the lithium cells in mobiles are designed to be charged as quickly as possible for convenience while internal electronics regulates the charge to ensure battery life. That’s why you’ll never see trickle or high power chargers for phones. The fast chargers are charging at the optimum safe rate for the battery and the only reason we have slow home chargers is down to the cost of the charging unit and how much power they can supply from a three-pin plug. Whether
  4. These are just technical issues that can and will be sorted out. From what I understand, used batteries do have a value and several car makes have partnered with power companies to make use of them as backup storage that could help to eliminate the risk of blackouts. Depending on which website you look at it's either an environmental nightmare or a brilliant opportunity for the power industry. The neysayers would have you believe that there will be an enormous mountain of scrap cars, all having different batteries and nobody has a clue about how to deal with them. Others suggest all man
  5. So based on these figures, the car could probably get you to St Ives with just one pit stop assuming you start off fully charged. The upper figures are a bit academic because nobody would run a car down to the point where it conks out, well not if they have any sense and that's no different than with a petrol car. And when it comes to charging, you don't need to brim the battery especially if your in a rush, again much the same as you do with a normal car. Course the battery takes time to charge but that's not really a problem unless you stand there watching it. After a three hour drive
  6. But people prefer to use personal transport so rather than trying to change what they want, why not do something that helps instead. People are not going to pay £1000+ when they can do it for £13 and risk catching Corona virus on a crowded train.
  7. Oh come on Sid, why take things down to the lowest common denominator. There are some cars (but not many) that are the mopeds of the electric car world with a 70-mile range but people who buy them know they’re just run-arounds. As for 8-hour charging, that’s only if you plug them into the three-pin socket at home which you can’t do on the motorways. Leaving out the extremes, a more typical electric family car will beat the train every time, even with stops for a recharge and cost a fraction of the train price. Bill
  8. Driving to St Ives takes about 5.5 hours by car, call it 6 with a break and uses about £70 in petrol. Even if you didn’t take your car, the train takes over 8 hours and costs between £150/£410 per person so a family trip would probably cost well over a £1,000 even off peak. An electric car should do it in the same time as a normal car but only uses £13 of electricity and even if you had to stop twice to recharge, it’d still be quicker than the train. Bill
  9. The companies will only make the cars that people want and more importantly can afford. On average, we only drive 20 miles a day (or a week in my case) so the current offerings with a typical range of 100-150 miles are acceptable and affordable so at the moment that's what they'll make. How far a car will go without refuelling is important but for most it’s not the primary consideration. Even the expensive Teslas only manage a about 350 miles, so one that does 500 would be so costly it probably wouldn’t sell. As for the charging, as I’ve said before, I don’t think it’s quite the issue tha
  10. Well for the younger generation this is just a mild flu like thing that's been blown out of proportion so to many of them it's just not that important which is a rather selfish point of view. And speaking of common sense, it's not just lacking in the younger generation. Iv'e just got back from Sainsburys where the shelves of toilet rolls were down to about 25%. One bloke passed us with a trolley absolutely full of rolls. The wife saw him coming and told me not to say anything, but stuff it, he deserved to be called a plonker! Does a beef stake actually help with a black eye Bill
  11. But the thing is it seems to be the more affluent countries where the spread of infection is the greatest and i think foreign travel has been the root cause. My wife told me that she saw something on telly yesterday about a school that despite everything was still planning to take kids on a school trip to northern Italy. Bonkers! Bill
  12. I'm going to take your good advice Asp and go to the pub. Can't be to careful can you. Edit Bugger! cars got a flat battery looks like I might have to get your prescribed remedy locally. Bill
  13. That’d make sense, a big on/off switch a bit like the emergency cut off switches you see on busses. I think the batteries at several hundred volts would still be risky so maybe the battery manufacturers need to do something similar to reduces the voltage down in an emergency. From what I’ve read, the batteries in formula 1 cars run at 1Kv+ which is about four times the voltage of a standard road car and it’s expected that in future most cars will follow this trend. I think the logic is that higher voltages don't need expensive, heavy lossy conductors thereby increasing overall effici
  14. I’m pretty sure that electric cars would have an automatic cut off device like that of a conventional car that in the event of an accident would automatically disconnect all the higher voltages. But as you can’t see electricity, anyone dealing with a crash situation would need to understand the risks involved and take the necessary safety measures. More and more cars are going this way so the emergency services and breakdown people will obviously need to be trained to deal with this rather than calling out an expert every time. Bill
  15. The same with me. As it stands, I don't think the insurance covers this sort of thing unless the government warns against travel to a specific location. Bill
  16. Well at least with no petrol there’s no chance of a petrol tank explosion so not quite as big an issue. As for the breaking down, well there’s no complex engine to go wrong so in theory they shouldn’t conk out anywhere near as much as a conventional car. Looks like the AA who rely on breakdowns will need to change their plans. Bill
  17. BTW that friend of mine that was due to fly out to Tenerife on Friday had second thoughts and cancelled his holiday at the last moment. He said for the sake of a couple of hundred quid it just wasn't worth the risk of getting the bug, getting stuck out there and most importantly appearing to be irresponsible given all his palls were at the age where the risk was greatest.

    Buying Wood

    At those sorts of lengths your not going to pick it up yourself and you'll need to have it delivered. When I was building my extension a couple of years back I just ordered the stuff on line. The large suppliers offer the biggest range, give the best prices and have a network of local depots. Bill
  19. If there was a large steel works its most likely that it would be near the railway but I've never heard of this, maybe he's got his lines crossed. Was there was a line running down Dallam Lane with some pretty big industrial units on the other side.??? Bill
  20. From what I've read, the mortality rate is ten time higher for this virus so it has the potential to see off a lot of us oldies. One of the blokes I sit with in the pub is due to fly out today for a week in Tenerife. The others in our group said jokingly that he'd have to sit at another table for 14 days when he gets back but maybe they weren't joking. Bill
  21. That’s true in most cases but the Mersey’s tidal so no mater how much dredging you do, when the tide comes in the water levels rise and that’s when the flooding gets bad. I think if we could do a Canute and make the tide stay out, we’d have a greater height differential so water could flow away faster. On a spring tide, the water flows right over the town weir and goes up as far as the one at Woolston. I thought the world had tipped on its axis or something when I once saw the water running backwards through Woolston park. It was like a mini tsunami that back washed all the crap from some
  22. Just been thinking more about this dredging thing and if it would have any effect? Suppose instead of just dredging out a few feet of mud, we could dredge down a mile deep, and do it all the way to Liverpool. Surely the resulting big hole would just fill up with water and within a few minutes it would be back to exactly where it started from and that mile of water would simply stay there doing nothing forever. Or have I got that completely wrong? Bill 😊
  23. Just had a package delivered direct from China. The wife suggested I spray it with Detol before I go any further. I didn't. Let you all know in 14 days Bill
  24. It does seem a bit extreme when you look at the current numbers but if we did nothing it could end up being bad. Some say it’s just like a mild version of the flu which makes us feel it’s not that bad but while people can die of the flu, I think with this one, it’s about one in a hundred infected people that end up dying. Do the sums, if it spreads as easy as flu and if only 10% of the population caught it, it would kill 80 thousand people in the UK each year. That’s a lot for something that we can hopefully prevent. Bill :)
  25. My wife’s in panic mode right now having just shelled out a small fortune to take the family and grand kids to Disney World in Florida. The holiday is booked for April and she’s worried that if the situation gets bad here, the US could end up restricting travel from the UK. Plus, if it gets bad over there, places like Disney might well end up being closed as well. Bill
