Seat Mii Electric has around 600 preorders here in Finland. 5 were registered in January, seems that they are registered for Seat importer. 50 were registered in February. Haven’t yet seen any around here (they are divided around the country so may take time to notice one...)

At Oulu’s latitude the summer days are a lot longer so electricity from solar panels. Day length sort of compensates for winter darkness... if that summertime electricity could be stored with reasonable cost it would be Very Good Thing. Not that I’m holding my breath waiting.

I have read somewhere that a persons water consumption in official statistics includes also water used in food and stuff that the person buys or uses in some manner, so whatever we drink and use in food, washing etc is usually lot less than the totals in statistics... as I haven’t looked at thsi lately the statistics might include also the water that industries use, divided with state population.

Here in Finland Seat importer announced a small model Seat Mii Electric - 260 km range, so would have been adequate for my needs. Price was for two models, either about 15,500 € or a thousand more. I contacted the seller and they said that they do not take reservations any more and are selling deliveries for the next July.

Price includes special offer from Seat and national subsidy so the ’real’ price would be 4,000 more. I think I will pass this time and see whta is the situation next spring - I can arrange my traffic needs so that I can live without a car if it comes to that...

Weeellll... there are other opinions or discussins on the matter

In Britain there were several rail gauges in use so it would be interesting to have some more rigorous information why this specific gauge was selected.

I intended to add something about british gauges but my browser has a hiccup so perhaps later if more discussion is warranted...

Hmm. I have a feeling that british parliament has difficulty in believing that the deal with EU is what it is, no more negotiations available. And as May’s government hangs on with North Ireland minor party etc.... (sarc) Perhaps the best NI solution would be that EU buys it from Britain. There are similar cases, Napoleon sold Louisiana to US and Russia sold Alaska to US. The area would be declared some kind of separate area with some special rights etc, no? (/sarc)

As I have not seen this linked here, islandboy at peak oil barrel site is writing at least three articles about commercial vehicles. As there might be people who are interested, here is link to first one

Second one is also out.

Interesting quote:

A September 19, 2018 article from titled, With Proterra Investment, Daimler Pushes Electric Bus Development stated,

”Proterra opened a factory in the City of Industry, just east of Los Angeles, last year. It said the plant would be capable of building 400 electric buses annually in its 100,000-square-foot space.”
Again these numbers should be seen in the context of 1,900 electric buses a week being manufactured in China.

The track options have been studied and it seems none of them could be profitable, so let’s hope that this amounts to nothing... but during the last few years the politicians have been able to ignore the reality in other matters, we should be not too hopeful.

Weeeelll... moon dust just got a lot more dangerous...

From New Scientist:

To estimate how many radicals would be produced in humans after exposure to lunar dust, Donald Hendrix at Stony Brook University, New York, and his colleagues took dust from two iron-rich minerals – olivine and augite – found on the moon, and soaked it in a liquid that simulates human lung fluid.

After 15 minutes, the two minerals had released about nine times more hydroxyl radicals per litre of fluid than quartz dust, which is highly toxic.

I do suspect that as we are adapted to our environment the very technical environment we would be forced to live in Moon and Mars (and also the gravity is weaker among other things) would be very problematic on many levels...

I do not have actual numbers but eyeballing the Baltic sea ice perhaps since 2001 or so, the ice area has been consistently below the average. Just been looking at the simple comparison charts... oh, and the open watr temepratures have also been above average.

Not sure if people follow the PeakOilBarrel pages, recently there was interesting post by dr Minq Li from University of Utah where conclusin seems to be that globally oil production reaches the maximum around 2021. Individual countries can go much further, 40’s etc.

Cannot say if the evaluations are too optimistic or otherwise, using official sources etc, but if interested here is the link...

Wierd or anecdotal?
The heat and drought in Sweden since May is not enough, we are still flying abroad more.
7-8% more travels this summer. The sun is obviously a lot better around the Mediterranean Sea or in the US.  ::)

They probably have a wish for skin cancer or something from higher UV radiation....

Here in Finland there has been very little rain for the last month and a half, so farmers are fearing losses... now some rain is promised, so perhaps we get 45 days of ongoing rain...

Walking the walk / Re: Is solar thermal heating out of date ?
« on: March 28, 2018, 08:15:36 PM »
Perhaps that depends on the location... e.g. We have lots of trees - not on our yard so cannot do much about them... and so only solar water heating is so far only practical, as electrical solar panels would be shadowed by some branches most of the day. Also there are two hills that create shadow early morning and late afternoon, and I’d guess that people living in houses on those hills would not be very delighted if I’d try to level the hills.......

Well, I have no idea if these flying cars / helicopters will work - but ages ago I read somewhere that a helicopter needs eight times the fuel as a similar size aeroplane for the same travel. And as it seems that we do not have good enough batteries for cars then these electric helicopters are a waste of resources and will be available only for the more well-to-do...

The finnish astornomical society, Ursa, ( ) has calculated where the meteor landed from received reports. Probably now the remnants are covered in snow, so there will be an attempt to find some of them in the spring.

This year’s pics seem to have a wrong year?

« on: September 19, 2017, 07:37:47 PM »
I have driven on US roads (e.g. Boston in winter when I had to go near the saltwater truck to get my windscreen clear of the snow as the car's windscreen water (can't remember the name for it in english now...) ran out veery quickly...) and when I compare it to roads here in Finland the conditions are quite different... here use of studs on wheels is very common and the road surface is accordingly in need of redoing in three to several years, depending on traffic. Just wondering what that saltwater or studs would do to a glasslike surface... at least scrathcing, electric shorts in short order...

So perhaps those 'solar roads' could be built in places that do not have much need of maintenance and wear and tear on the road surface. Difficult to imagine such a place... also all trees and buildings would need to be removed or situated far enough so that they do not shadow the surface too much...

I have a sailing boat where the old diesel engine was replaced with electric inboard motor with largish batteries in 2004. Year ago I upgraded the old solar panel that had taken care of the house batteries for more than 15 years with more efficient panels so that now I can charge also the engine batteries at 24 volts with a suitable controller. In theory I could now use the panels to directly move the boat at one knot in calm weather... usually I wait for the wind...
This of course requires different attitude to sailing, as the batteries can move the boat for something like 5 to 30 sea miles, depending on the used speed. Usual mode for diesel using sailing boats is to start the iron genoa when speed drops to somewhere like 2 to 4 knots or would require beating into wind - for me it's better to accept even very slow sailing and contemplate the sea, islands etc...

The balance of heating and cooling depends of course on the length of the corresponding periods, but as such I've beentold by air heatpump installers that one would use three times the energy to cool down a house compared to heating it same amount of degrees...

Radio news here told that a 4.0 earthquake would have taken place...

NeilT mentioned Baltic Sea in his post above. I do not have now any exact info about ice hereabouts, but as a boat owner I have sort of keen interest on when ice comes and goes... generally the ice has been coming later, melting earlier and having less are in last 10 years or so. Last time that the Gulf of Finland had full ice coverage was sometime in the start of 2000's - and that only to Hanko level...

I'm trying to find some data from Finnish Meteorological Institute about ice cover, etc - at least the data is not easily found on their site...

Today's news told that Saudis etc have reached an agreement on curbing oil production down to 32,5 million barrels a day, if I heard right. I wonder whether this happens (somebody needs a bit more money) or is this something about 'we can't produce that much anymore, let's agree on something...'

Finnish Technical university in Lappeenranta has developed a global model on how the renewable energy could be distributed...

Simulation brings global 100% renewable electricity system alive for the first time

A new model developed by Lappeenranta University of Technology (LUT) shows how an electricity system mainly based on solar and wind works in all regions of the world. It shows the functioning of an electricity system that fulfils the targets set by the Paris agreement by using only renewable energy sources.

The global Internet of Energy Model visualizes a 100 percent renewable energy system (100%RE) for the electricity sector for 2030. It can do this for the entire world which, in the model, has been structured into 145 regions, which are all visualised, and aggregated to 9 major world regions.

"With the simulation, anyone can explore what a renewable electricity system would look like. This is the first time scientists have been able to do this on a global scale." says Christian Breyer, LUT Solar Economy Professor and a leading scientist behind the model.

At least here in Finland the air to air heat pumps are considered to work up to -20 C for the best models; also it's said that they need to be kept running even when colder, to prevent outside unit from freezing - at least some models are 'thawed' at some point with sort of reversing the heatflow from inside the house to outside unit, if I have understood the workings correctly.

Last winter was not very cold hereabouts so cannot say if there would be real issues in even colder situations - at least the different versions, air to air, air to water etc have sold well here.

Somehow looks similar to smaller scale stuff in local boat harbour - you see ice there and it's clearly changing color, thinning, there is some open water here and there, and when it all goes it disappears very rapidly, many times in a day or so (I'm usually working at boat every day in spring...). I'm sort of afraid that something similar in lafge scale could happen in the arctic...

JMG has just put up an article about '' about why the different climate activists etc have not been able to achieve results... main issue in his opinion is that the message has been only doom and warnings - that people need also something positive in the messsage etc. and that in many aspects the relevant experts haven't succeeded politically...

In comments are already several thoughtful comments on this - and probably there will be lot more later... one that I did not much notice was that for many ordinary people the threats are somewhere in 'far' future or that 'they will think of something'.  Also the discussions in this forum show that issues are complicated and all that - how to communicate those so that enough people in all layers or classes of our societies really take action? I have no idea...

It seems that prices are a bit steeper than ordinary electric bikes. German site has a configurator that shows price for minimum battery as 26.849,00 €.

Of course you get a lot more than in a e-bike but still...

Does that definition sort (5 years in row) sort of ignore the variability of ice cover etc - winters will rebuild the ice for a long time (at least one year.... ;) ) and the following year could have weather that changes the melt rate to 1.1 million or greater in September... so bit more flexible definition might be better?

I'm usually following the rather shorter than Mauna Loa developments in Pallas-Sammaltunturi measuring station in northern Finland. It seems that it took about 4 years for the average value to go from 390 to 400, 2010 to 2014, so the 420 mentioned above would happen with same rate near the 2022.
