Indeed, but if you go much further back CO2 has been higher as have temperatures.

 

Could you give a date or time period for this? Was it at a time when humans were living here?

So there's no doubt that life can survive but it had plenty of time to adapt as those maxima happened over millions and tens of millions of years. What's coming is (on a geological scale) going to be near instant and it's going to play havoc with life. A plant that can move its range and evolve over millennia to suit previous warm periods is not going to manage that if the predicted speed of change proves to be accurate and is decades or centuries. We need urgent action. Urgent. Burying your head in the sand will solve nothing.

There is life at the bottom of the ocean living in hydrothermal vents that are completely inhospitable to almost every other living creature on the planet but that doesn't help any other creature on the planet except the ones that can live in the hydrothermal vents.

 

I agree with you about the need for urgent action - I'm not the one burying my head in the sand.

Please do tell what different charging systems they have. The US has 110volt mains and we have 240volt if that's what you mean.

I've already provided a link to the British charging system so rather than have me waste far too much time typing it all you "please do" follow the link and read it make the comparisons for your self.

......Sounds like my mother in law (the inhospitable bit, not the living at the bottom of the ocean bit).

 

 

Ooops, serious thread rusty, stop that!

Can't find your link, please repeat it or your post number.

Some of the ground-source heat pump engineers around me...say they are removing more than they are installing as they just don't suit the UK.

[MtB]

Heat pumps don't suit the uk whatever type, currently.

I quoted you and posted a link to zap-map, this is the link for their home page which will give you a better range of options to explore.

But you might also find the myenergi interesting they have an interesting range of domestic chargers and other connected tech

 

https://myenergi.com

 

There are also quite a lot of commercial chargers available for smaller businesses - I looked into this for a business plan I'm thinking about at the moment and found some quite interesting stuff just by googling around. One of the companies that I found doing this was Pod Point.

The problem is that you are debating what I said they were doing which is all very well and good if I have given you the whole story, I said what I believed to be a factual but condensed version of what I have read on the subject. But as this system of charging cars has been up and running in the real world and is doing what you say it can't do then that would suggest that either I don't have the full story for you or your maths is wrong, Which is it most likely to be? So while it might be fun to run it into the ground it might also be wise to double check with the source first. 

 

But you are still linking to an American site - the Americans have a slightly different charging system to us Europeans. ?

A lot of American electric ovens are actually 240V with the house having a centre tapped 240 supply giving 2 120V circuits (well that's how they do it in Maine)

I really can't comment on how all the different states do it as I don't have any need to go into the intricacies of it but there are differences between America as a generalisation and Britain.

Yes but the point is 240V is present in American houses - they just don't use it for most household appliances. They may well use it for EV charging.

As a retired electrical engineer, specialising in battery and power systems, I think I understand the whole story and the maths involved, but please feel free to correct me if I am wrong, I am always willing to learn.

 

There are only two possibilities for these lamp post chargers. Either they are using the capacity released by changing from sodium discharge lights to LED lights, in which case the charger can only have a low output with associated long charge times, or they have upgraded the transformer and cabling supplying the street lights, in which case quicker charging can be achieved, but at a much increased installation cost.

 

In today's marketing led world, image is everything and is often prioritised over functionality. A situation exacerbated by the number of people today who don't understand how things work. This is evidenced by manufacturers using new meaningless terms such as "skyactiv technology" rather than stating what it is that they do differently to their competitors

 

I look forward to the day when affordable and useable EV's, including an effective (in terms of charge time and geographical distribution) national charging network are available, but for me, that isn't yet the case and pretending it is doesn't help anyone. After all people having positive experiences tell others who then buy, but those telling of negative experiences have the opposite effect, so why do marketing people do this? Could it be because people no longer question what they are told?

 

Yes, the Americans use a different electrical supply voltage and frequency to us (110 volts ac at 60 Hz instead of our 230 volts ac at 50 Hz), but from a charger point of view this is irrelevant.

 

A charger broadly comprises two parts, the ac (alternating input) input stage and the DC (direct current) output stage. The output stage will be the same for any specific charger and is designed to charge a particular type of battery. This enables EV manufacturers to use the same battery for their different worldwide markets.

exactly. 

 

Wiki : Many areas, such as the US, which use (nominally) 120 V, make use of three-wire, split-phase 240 V systems to supply large appliances. In this system a 240 V supply has a centre-tapped neutral to give two 120 V supplies which can also supply 240 V to loads connected between the two line wires.

  I said to you -  don't quote me go to the source if once you've done that and you are still coming to the conclusion that the system isn't working the I suggest that its them you need to speak to not me.

So how do we get 7kW systems installed at popular visitor mooring locations like Gnosall, Middlewich and Nantwich?  Let not even start at more isolated places like Coole Pilate

We're in complete agreement but we're posting past each other at the deniers.

 

Historical record here: https://en.wikipedia.org/wiki/Geologic_temperature_record

 

I was agreeing that, factually, yes, there have been times with much higher temperatures in the far distant past. However, the adjustment periods were in the millions of years. If we achieve it quickly, there won't be time for current lifeforms to adapt, move and evolve in order to survive.

Don’t be daft...we have to tow a flat covered in panels....? 

 

I just was refuelled by Nb Alton and got gas & solid fuel...enough to last me a month or so....all sorted in 10-15mins....hard to do that with electric.

It's obvious, a big diesel generator in a shed.  I'm sure CaRT will stump up the cash.

Thats funny I did nothing at all and mine refueled itself for free, and when its not doing that it creates hot water for free?

So how much more power capacity would you need to add to allow you do a week of 8 hour cruising days in bad weather and to have 20 gallons of nice hot water available?

I an going to have to tell the wallers to remove theirs because it doesnt work, yet clearly for the last ten years it has worked very well, also the post office in Auchencairn that has to have windows open in winter because its so warm! and Davids garage as well he needs to remove those air source heaters that produce warm dry air or cool air in the summer as they cant possibly work

Generalisation is not the way to go systems that are correctly sized and installed work great

Yes but I boat for 8 hours a day all year round when I’m travelling.....plus having a sensible 50ft nb we don’t have the roof space to put that much solar...plus I like a clear roof!!

Yes I know that and it was mentioned about twenty posts back. I've got a 3 phase supply coming into my house so I can get 415 volts.  The US has got a nominal 120 volt supply and the UK has 230volt.

Why do I need 20 gallons of hot water? and on sunny days what I have does the cruising for 8 hours not that I would ever do that I would have died of boredom after 3 hours

Shortly I wil have added another 5 batteries to increase my poor weather range to 8 hours and added another 900 watts of solar which means my cruising life be ok for me what others are going to do when diesel is 10 squids a litre is of no concern to me really

Well in the future you will enjoy bowhauling your clear roofed narrowboat!

Look this is all tongue in cheek stuff, but the government is going to make boaters lives difficult and expensive, we are going to have to change like it or not, and remember there are no government diesel pumps on the road or on the cut, so its our problem not theirs, to sort out how we move boats in the future, and we will have anti pollution laws to contend with. So start thinking about what you will do in the future not what you did in the past, these consultations arnt being done for fun they are warnings that action is going to be taken, and we know that by 2025 new boats will be zero emissions because the consultation say so
