Policy and solutions / Re: Solar Roadways
« 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...

Walking the walk / Re: Gardening

Silkman, and others: you need to be careful with those nets as birds can get caught in them. I've seen such things in neighbours garden long time ago... especially when bushes started to have the berries...

There have been some temporary railways on ice in the northest part of Baltic after the WWII when an exploded bridge was rebuilt. Otherwise, there have been no railways on e.g. on the Finnish Gulf...

Pics of steam engine going thru water is rather unsettling, water splashing and passengers standing in carriage doorways as if ready to jump if the ice does crack...

News today told that ice area in Baltic is lowest ever measured for the date. No details...

Arctic sea ice / Re: The 2016/2017 freezing season
« on: January 10, 2017, 09:15:53 PM »
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...

Splendid! Thank you Neven for your perseverance!

« on: November 30, 2016, 10:00:08 PM »
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.

Arctic sea ice / Re: What the Buoys are telling
« on: August 17, 2016, 10:31:26 AM »
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...

And as an anecdote of how the governments, press, nearly everybody thinks: today's paper had the editorial demanding more growth and so on, BAU etc. And to insult all the intelligent people on this forum, more growth -> more energy and resource use and so forth...

No politician wishes or dares to say that current situation/economy/whatever is as good as it will ever be, it could be downhill from now on...

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?

Science / Re: Mauna Loa CO2
« on: April 20, 2016, 09:57:40 AM »
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.

An osprey nest on top of a seamark in Finnish archipelago. Live feed and seemingly rather slow static picture. Also other sites in link 'MUITA KAMEROITA' (= other cameras). There used to be english version but I could not see it now...

« on: February 25, 2016, 12:37:20 PM »
Well, perhaps there is something taking place... we'llsee if this means much.

I'm sort of wondering that in Russia situation, with oil price, cost of doing even minor military action etc there is some weak hope that some progress will be made.

OTOH, Europe has something like 300 million people so few million refugees might have only local influence - but if politicians wish to promote some agenda they are of course usable source  material to whatever their policy is (xenophobia, racism, fear of other, vigorous new people to workforce.... )

« on: January 10, 2016, 09:34:59 PM »
Inveeetment environment in India could look a bit difficult from foreign viewpoint; a few years ago India tax officials required Nokia (the ex phone maker, you know...) to pay additional taxes although there was an agreement between Finland and India that India should not demand anything in this context. Don't know the details, but I think that the relevant factories in India remained with Nokia and were not transferred to Microsoft when the whole phone business was sold to MS.

So perhaps there is some wariness in some corners of big businesses - they might suspect that the business environment in India is  not stable enough...

So far I haven't had anything to add to the several interesting discussions by persons who know a lot more than I... but at last something that I haven't yet noticed in the forums. A Finnish electric bus company is now building 12 fast-charging buses for testing in Helsinki area:

I'll go and get a ride in one when they get them to traffic... there will be probably quite a few news about them in finnish media at that point.

Also they have got contract for something similar in Copenhagen.

As I have tried more unsuccesfully tried to get photos of mostly snow, only thing that I can now add (you probably know that...) is to use RAW images and postprocess. Perhaps stacking multiple images in suitable programs etc could help...
