New Engine Dilemma

I don't think that not being able to see a hydrogen flame is a big deal. Our modern Worcester Bosch heating boiler has a blue LED which glows when the boiler is heating water. The actual combustion process is buried in the guts of the unit.

It's a big deal when you get a tea towel over a hob ring that is still lit on low.

Easy enough to do with gas and radiant electric rings today. I suspect we will all be kitted out with electric induction hobs if and when all this comes to pass. I don't know whether or not these will burn a carelessly placed tea towel.

[Smoggy]

Induction hobs barely get warm, usually only conduction from the pan itself, I believe it's the reaction between the hob and the ferrous base of the pan that heats the pan rather than the heat of the hob/flame transferring to the pan.

They won't work with an aluminium pot.

 

[vanessan]

Induction hobs are incredibly quick at heating pans, even faster than gas. I think they’re more controllable too. They only work with pans with magnetic bases so it’s easy to identify if one will work or not. And yes, it’s the residual heat from a hot pan that is left on the hob. Usually a light will indicate residual heat even if the hob is turned off. I love ‘em!

Just replaced our dual electric 120v / meths hob with an induction one from the States. Fantastic - works very well, fast and efficient, and improves aesthetics too. Cost about £230 inc freight and customs. Took 10 days.

really interesting - any chance you can provide a link to see what you have bought?

Please explain ?

 

I shall be taking no action until such time as propelling my boat by diesel becomes illegal or impractical. I ssuspect that this will not happen in my lifetime.

Globally, Diesel is cleaner than petrol (for the atmosphere ozone layer etc.) locally, petrol is cleaner than diesel, so work out whether your priorities are to save Norwich or the world !

Don't forget that the government of the day is only interestedin becominjg the government of tomorrow too. That applies to all politicalparties.

Personally, I believe that Global pollution is much more important than local air quality but that is an attitude that wins no votes!

Only just caught up on this (been away!) but yeah basically as others have said it's not generally considered economical to rebuild a Nanni / Beta (Kubota) engine so people seem to just replace them.

With a BMC / Perkins (dependent upon model of course) it is often quite economical to do a major overhaul. If the likes of cylinder liners, pistons, rings, con rods, bearings etc have been replaced and of course the injection pump overhauled / replaced then what you're left with isn't far off a new engine. But at a lower price.

I also tend to think that a lot of yards advise against overhauling because A) they don't have the expertise in-house and B) there is a lot less markup on getting a diesel specialist to do a rebuild than there is in selling the customer a new engine at retail price.

[Vaughan]

I have just remembered something.

The BMC 1.5 block can be re-bored 3 times and both the Perkins and BMC crank journals can be re-turned 3 times. I am not so sure that would be possible with the base Kubota engine.

[annv]

Hi Vaughan i would  say 60 thou max 20 per rebore unless scored then you resleave one could say that the Kobota would do double the hours that a BMC could do under normal conditions , i will ask my go to engine reborer although cant see why they cant be resleaved certainly a thinner block but no chain just gears for camshaft drive and pump so quieter.

In a bit of a dilemma, there’s a 1.5 bmc on my alpha 32 and ive done the usual looking at new engine packages but I love the bmc but also appreciate we may have to go hybrid in a few years so I’m tempted to have the bmc rebuilt  any one else had similar thoughts, I really wanted to keep this boat simple as a promise was made to my late dad but he knew what I’m like with boats 

Seems it time to panic  the government are proposing to stop fossil fuel propulsion on new boats in 2050

Like the Perkins, but with those you can always choose to change the liners and hope to re-use the original pistons.

when they manage to get electric posts installed at all the moorings like hardley cross, then i will start believing it, first they have to get someone willing to supply electricity to such remote sites, then they have to find the money to enable them to pay for it. by my estimate Hardley cross will easily cost 6 figures. money that will never be recouped during the asset lifespan.

Things are going to change before then!  In the last month or so the marine industry heard rumours the EU are working on RCD 3 which may take effect from around 2027.  What this means is anyone’s guess at present, if I’m allowed to I’ll let you know if I hear anything.

Ah but we are no longer in the EU and the way they sulk when they can't get their own way I am not sorry, having grown up, lived and worked through various scenarios I am at an age where I take everything with a pinch of salt and believe things when I see them with my own eyes, sorry but life is for living you only get one go at it if people want to spend their life worrying about could be's and maybe's that's up to them but life is to short to waste.

Nope, we are not.  But whatever they come up with will still affect new boats / engines in some way, shape or form.  I'm not worrying about it, just need to be aware for my job.

Fair enough my comment was more a general observation on the current rush to throw the baby out with the bathwater, I have no problem with adopting new technology once its proven as long as it is sustainable and practical, at the moment we are in a headlong rush to ditch the old just to satisfy the latest the end is night movements.

So did I, in my time.  If you keep up to date on these things you can make plans so they don't catch you out when the time comes.

That said, the present HGV delivery crisis has been staring everyone in the face for at least the last 15 years and yet only now, when the bubble bursts, do we suddenly realise how totally we rely on a road transport logistics infrastructure.

If you think I'm off topic, no!  The same thing will happen with electric cars and boats.  We will all be forced to buy and invest and then sure enough, oh dear!  There is not enough national power generation to charge the blasted things!

We know this now!  It is staring us in the face.  But you can bet that by 2030 no-one in government will have done anything about it.

Just to add that wind power has failed this year. 
Reserve coal power plants were brought online. 
Nuclear power anyone?

That's an idea - swap your old Nani or BMC for a mini nuclear powered unit, like a Trident submarine 😂

Hi I do believe there my be some cheap French ones for sale soon and it gets better they dont need enriched uranium fuel ether. John

Actually the quote I saw said gas prices had gone up.

what the true situation was that mid August we had three full days without using coal generation, one of the two remaining coal fired power stations in the country then after 3 days of really nice weather in august, then fired its boilers back up and was generating 2% of the national consumption (about 1 GW) this may partly have been due to a fire at the UK end of a cross channel electricity supply line that took out 1 GW of our import capacity.

in the news though, this start up after 3 days not running was headlined as Gas shortage forces government to bring coal fired power stations out of retirement, in reality they had been shut down for 3 whole days due to low demand, and then bought back on line.

Coal fired power stations are slowly being phased out of the grid, but the 2 remaining are there to fill the gaps so to speak, they are slowly being decommissioned, with full shutdown planned for 2025.

but the real interest is how the news headlines made it sound so much worse than reality, much in the same manner they have done to cause panic buying of fuel.

we only have around 4.2 Gw of capacity left as coal, all the rest has already been decommissioned. and we are not even using the full output available

Today we are currently running a coal free day 0% of energy from coal or oil

Voice of reason there. But if the Bloomberg article is correct, wind power failed to fill in the shortages some days in august . So if an all electric future is on the cards, I’d rather build nuclear
