Autonomous Vehicle
14 Jul 2021
As it turned out, I didn't manage to get a coffee on my lunchtime coffee trip, as Imagine That were briefly shut down by a Covid-19 exposure notification (false alarm, it seems.) On the plus side, my trip was made worthwhile by spotting a couple of people from the University of Bath Mechanical Engineering Department testing an autonomous body-finding catamaran, which isn't a phrase I was ever expecting to write...
I recently indulged myself by buying a little piece of history. I've mentioned Samuel Loxton and featured and linked to his drawings before, often in the eminently browsable Loxton Collection albums that Bristol Libraries has on Flickr. So when I saw a Loxton drawing of Hotwells pop up on eBay, I decided to get myself a little treat.
I don't think there's any Loxton drawing that features the road I actually live in—it's not very visible from anywhere else, not being one of these Clifton terraces that's perched at the top of a hill, or anything like that, and it's invisible in most views of the area. However, this Loxton drawing, Hotwells, Looking across the river from near the Clifton Bridge station, is probably the closest near-miss I've seen.
I decided to wander out one morning and see if I could reproduce the picture, and also take a photo or two of what's now become of the Clifton Bridge Station, which is still just about discernible in places.
(Then on an even stranger whim I decided to check out a possible little cut-through from Cumberland Road to the harbourside I'd been eyeing up on my commute to work, so walked to Wapping Wharf for a croissant via this potential new route, but that bit's not quite as interesting...)
I'm afraid that this is a bit of a badly-curated wander, where I mostly just popped out to find out a little of the history of Underfall Yard and poke around the various open workshops, and, in hindsight, really didn't take pictures in any kind of coherent order. So there's a lot of pictures, but they don't really tell the story that, in hindsight, I seem to have been trying to tell, of the unusual electrical substation in Avon Crescent, the Bristol Electricity that predates the National Grid but is still in use, the history of the hydraulic power house... It's a bit of a mess.
But I suppose sometimes these wanders—always chronologically presented in the order I walked and took photos—simply will sometimes be a bit of a mess. Let's hope you still get something out of it, anyway...
Via this Tweet and taken from KYP Bristol, showing the interior with a couple of Westinghouse rotary converters and a Peebles-La Cour motor converter, assuming this picture ties up roughly with this 1908 Institute of Mechanical Engineers' visit to works.
You can see a picture of similar Westinghouse converters to the two at the back in the Wikipedia rotary converter page and a Peebles converter that looks very similar to the one in the foreground on the cover of the Peebles motor converter catalogue in the sidebar of their entry in Grace's Guide. I'm guessing the additions on the ends of the Westinghouse converters were for different voltages? A rotary converter is basically a motor connected to a dynamo, so extra dynamos with different windings would give you different voltage outputs, I suppose, but I know very little about power generation.
I guess the gearing is changed in the traditional way, by someone with a stick moving the belts across to the next diameters along. Apparently that used to be the emergency stop in the old days, too, some bloke poking at the belts with a pole until they fell off. Probably not ideal if it was to stop someone being sucked into the mechanism...
I presume they're the brushes and slip rings of the electric pump motor, though I'm not sure what kind of motor this is, to be honest.
Leigh Woods Walk
14 Mar 2021
An enormous walk today, or at least it felt enormous. My feet are sore, anyway. I started off recreating a couple of local historical photos in Hotwells, but then headed for my traditional walk along the towpath in the Avon Gorge to the far extreme of Leigh Woods, up and through the woods to the height of the Suspension Bridge, finally crossing into Clifton Village for a well-deserved vanilla latte.
I say "traditional" because this used to be a very regular route for me, first walking, years and years ago, and later jogging—this route combined with a circuit of the Downs on the other side used to be my way of making sure I was fit to do a half-marathon (I did six of them in total, between 2010 and 2014).
I miss the routine of this walk, even though it's a long way and it used to pretty much wipe me out when I did it—I'd come back home and collapse and do very little for the rest of the day. But perhaps that's what Sundays are for, and I should try to remember that.
Doing this walk regularly was quite a meditative experience. Not so much of that today, but once I got to the further extreme of the towpath, where the roar of the Portway traffic on the other side of the river dwindles and I turned into Leigh Woods to climb ever closer to birdsong and further from rushing cars, I did seem to recapture a little of the feeling of previous walks. (I would say my mind cleared, but I was mentally singing along to Life Without Buildings' The Leanover for most of the wander. There are worse songs to have stuck in one's head, though; it's a great track...)
Anyway. Apparently the walk made me more likely to ramble in words, too. I'll stop now :)
I test drove one of these in 2005 and loved it, but the more practical Mini Cooper won out in the end.
