« on: Today at 11:14:33 »
as an example on the cordless bit, the Dyson V11 has 25v battery at 3.6Ah capacity, so that is a maximum of 90Wh of useage.

If it the vac ran for only 10 minutes on a charge than thats a max of 540W but, Dyson quote 20 minutes so 270W of suction (and all motors are in the 90% efficeincy range so no gains of note here). Compare that to say corded which typically has the EU max of 1600W, and its easy to see why the cordless convenience cannot match the corded power  :y

I fail to understand the fascination with cordless stuff. It will always be limited by the laws of physics.

Same with lawn mowers. Work out how much energy a decent lawn mower needs to cut a lawn and then tell me they can fit that in the battery!

Battery tech works very well in devices where other energy sources are awkward and where intermittent power is needed, even at quite high power levels, but no good when you need continuous high power. My Dad recently bought a Stihl battery chainsaw, and it's a great bit of kit. The 2 stroke probably trumps it for power on a really thick trunk but I know what I prefer climbing a tree with!

Vacuum cleaners, though? Nope. I probably use it once or twice a fortnight (I'm not house proud!). I plug it in once to do the upstairs, and twice for the downstairs. Hardly enough inconvenience to warrant a crap battery model. ;D

Finally got fed up with unblocking the Dyson a couple of years back. Why they designed it with so many 90 degree angles in the dirty air path I'll never know.

Went to the hardware shop in the village who I like to support and he sold me me of these for 100.

Way more suction power than the Dyson. It actually lifts the carpets off the floor and sucks air through the pile!

Much lighter to move around the house and being a more commercially oriented design it's got a long mains cable and hose.

Great for cleaning the car too! I love it and would never go back. For the price of a Dyson I could get a new one of these every year.

All the parts and bags are compatible with the Numatic range so easy to get hold of, Not that I've ever needed to buy anything for it. I'm even still getting through the bags that came with it.

They are doomed to fail there will never be enough of a reserve to charge the infernal machines

I have a lefty/greenie mate who often enthuses about electric cars and the utopian days ahead when we are all trundling around in little milk floats, but when I point out inconvenient truths like Where is all the electricity going to come from? He gets mad and dismisses me as An effing denier!  ::)

He's good sport!  ;D

Ahh, yes, virtue signallers don't like seeing the inconvenient "big picture". ;)

If you have a suitable hot water supply  available but can't easily fit a mixer shower the Aqualisa Visage and Quartz ceiling fed showers might be worth a look although I notice they've facelifted them and considerably hiked the prices since I last bought one. ::)

These have a mixer and optionally a pump that can be mounted remotely in a loft or cupboard avoiding the need to chase pipework into the walls and replace tiling, and so on.

Electric showers just run at a constant heat output (so nothing in reserve - unless it has a low/high heat setting). Temperature is adjusted by changing the flow rate. A higher rated one will therefore just give you a faster flow rate (and electricity consumption) at a given temperature.

Worth checking what your electrical supply can cope with before getting a hugely powerful one, and if a circuit is already present, you'll need to consider its rating.

Apparently Boris has Covid again, so I dont suppose he will be able to answer any more questions for a while.  ::)


Has he ever actually answered a question?

Like how many kids he has?  ;D

Try starting with one he knows the answer to. ;)

Speaking of Renaults - I fitted the new turbo to mine today and reassembled everything.
Started it up and all good on that side of things. Running quite nicely - apart from oil pissing out high up on the cambelt end of the engine.
I suspect the cam seal has let go. Same thing happened a year ago when the original turbo died, and I replaced it with a second hand one.
If the turbo isnt spinning I assume the oil getting pumped to it doesnt drain very quickly and results in excessive oil pressure which causes the oil to find the weakest link so it can escape.
Its a complete PITFA.  >:( :'(

Oil pressure doesn't go anywhere near the camshaft seals and will be regulated by the relief valve in any case. Excessive crankcase pressure might do it, however.

Somebody told me the Marina was essentially 1950's design technology tarted up for the early seventies, and passed off as 'new'.

I don't think it pushed the boundary of what was possible in 1971. ;)

I prefer the All-Aggro.......not that it was much better.

Indeed it was. Most of it was Morris Minor bits carrying way more weight and power than they were designed for. Not really surprising it drove like Bambi on ice.
IIRC fleet managers liked the "simplicity" of the Ford RWD cars over the FWD models that had become BL's mainstay so BL tried to get some of that market by attaching bits of junk together. ;D

Around this time I did quite a lot of miles in an Alfasud 1.5ti. They may have rusted but they handled brilliantly. :y

Marina trivia fact.......the 4 door saloon and 2 door coupe used the same front doors, why is why they look too small on the coupe.

BL saving money, no doubt. ;D

I heard a rumour that BL management promised that the Marina was going to be a "blue sky" design "but we've got all those Landcrab doors to use up...". ;D

Don't knock the mighty shItal. I had a 1.7 Estate it was great as a student. Could pile loads of pi$$ed up engineering students in the back. ;D Not so many laydees, but I'm sure the addition of a mattress would have facilitated that had the opportunity arisen (which, naturally, it wouldn't).

Corners weren't so much fun. The 87 BHP it had, IIRC, was enough to test the chassis well beyond its capabilities. The 1.3 must have been dismal, though.

It was an absolute hoot in the snow.

I'm trying to understand the appeal of a rally car with a 1.3 A series in standard tune. :-\

It'll be fine. Especially as you don't have a DPF. :y

Just looked at the link and far canal! Castrol Edge! You are treating her. She won't thank you, being french. ;)
Pierre is trans?  :o
Well, the modern way is to ask it if it would like to be assigned a gender or remain non binary, apparently. ;D
Apparently, I have two astras. Actually just one, but it is non binary and wants to be referred to as 'they/them'. The garage keeps trying to charge me twice when I book them in for a service.
I bet driving them both there is entertaining. ;D

It shouldn't make much practical difference. 0w30 is just a little runnier when cold than 5w30.

Surprised you splashed out instead of finding a suitable chip pan to empty into it, TBH. ;)
