A new sub-genre of my experimental internet poetry! Is Google able to capture the essence of this blog?
Rules:
- Search your own site on Google, using site:[your site].
This ‘poem’ is based on results from site:elkement.wordpress.com.
- Open the first search result in a new tab.
- Pick one phrase from this page (your own content) and note it down as a new line of the poem.
- Open the next search result, pick the next line.
- Editing of phrases is not allowed, and you must not re-visit the pages already processed or re-shuffle the lines.
This is so-called poetry from the first three pages of search results, as usual combined with my images.
I’ll stay away from social media for a while so you have time to digest it!

Nothing you have not seen in more elaborate fashion elsewhere
the true connection between my diverse activities
a nitpicking stickler and painstaking submitter of DMCA complaints
a pioneer who did such an experiment long before the social media era
In past years I tried to eradicate it
a rotating alien-fighting device throwing darts
It is utterly exhausting
the phase portrait deviate from the circular shape
So what to do with all those old sites?
Steampunk seems to allude to a part of our common DNA
The tank will also be used as a cistern
shining laser light on the dark filament and analyzing the diffraction pattern
due to different spontaneous freezing temperatures of supercooled water.
I am in need of trivia.
mentally insert black and white images inspired by Philip K. Dick‘s short stories.
driving hansoms and communicating by wired telegrams.
We abandoned some gadgets and re-considered usage.
I finally added permanent redirects
you should try to use energy more efficiently first
Subconsciousness already takes the decision but you do not notice yet.
so there is no violation of energy conservation.
Don’t panic – I have left the lofty heights of political analysis for now!
As a fallible human you might give in to the most intrusive requester
denying cap-and-gown costume as I detest artificial Astroturf traditions
I have a secondary super-villain identity.
Here is a typical example of very volatile output:
the irony of being considered a notorious link scammer
salt crystals should easily glide downwards from a tilted plane.
It’s time to compare costs again
Otherwise the grass might always be greener over there.

How you manage to create order from entropy is always beyond me–it still has a beauty all its own, though.
I found myself, on numerous occasions, talking to friends about your system. I wonder if you could answer these questions for me?
– during the summer, what would be a ‘typical’ peak temperature reached in the tank? Perhaps a mean would do nicely here.
– what, would you estimate, is the highest percentage of ice you’ve ever had in the tank?
– what would be the practical limit for usability, regarding ice formation?
– approximately how many L or m^3 should the cistern be>
– NL is VERY rocky. Typically the bedrock is only barely covered (a few cm to about 25 cm) by topsoil so the cistern would have to be dug out by an excavator drill in a similar manner as are basements. With that in mind, would you have any recommended dimensions?
– is it practical to have the cistern underneath the house, basement fashion, or are there too many potential moisture problems?
– how do you recommend that the cistern be covered?
You may be wondering where all my questions are coming from. It’s mainly due to the fact that with our new hydro plant under construction I am expecting electricity costs to double and think that you guys may be on to something that can be practical here, too.
Good questions, Maurice – I’ll answer them below and I might turn this into a future blog post. I have also a post in the making with lots of figures that show the state of the system (all temperatures etc.) for different times of the year.
– Typical tank temperature in summer: See the red line in this image for the typical change of temperature
https://elkement.files.wordpress.com/2015/08/temperatures-performance-factors-july-2015.png?w=584&h=374 After the cold season the temperature is limited to 8°C to prepare for cooling – the collector is bypassed to keep the temperature constant. When the tank is used for passive cooling and ground is heated up by the sun, the temperature exceeds the set point. In autumn the temperature is limited to 20°C (max. temperature allowed by the heat pump vendor).
– Maximum ice: It was during last year’s ‘Ice Storage Challenge’ where we turned off the collector to simulate a harsher winter: The high score was 15m3 of ice: https://elkement.wordpress.com/2015/04/01/ice-storage-challenge-high-score/
Here I simulated the maximum ice for 20 years – we expect to hit the tank’s limit about every 10 years: https://elkement.wordpress.com/2015/01/28/more-ice-exploring-spacetime-of-climate-and-weather/
– Practical limit: We estimate that about 90% of the volume could be utilized.
The limiting condition is the slowly decreasing brine inlet temperature as the layer of ice that is cooled below 0°C. The heat pump stops working / switches to the backup heating element at brine temperatures of -6°C.
– Required tank volume: It depends on the energy needed by the building, especially in those months where ambient temperature is well below zero for 24 hours several days in a row. In our climate, the rule of thumb is about 1m3 volume in the tank and 1m2 of solar collector for about 1000 kWh of heating energy / year.
Here in Dec-Jan-Feb the solar collector does still harvest 75-80% of all the ambient energy needed. But these numbers will be different in your climate – I checked data for Regina, SK in the post linked above. For a worst case estimate:
-> Heating energy the building needs on such ‘ice days’ * 0,75 = ambient energy needed by the heat pump per day (assuming performance factor of 4)
-> Times number of days in typical ice periods, divide by latent heat of water, ~93kWh/m3
This calculation results in 20 days for our heating demands, equivalent to an extremely long period of frost by our standards.
(I have not factored in the contribution of ground – see next question.)
– Rocky underground. In a typical year here (ice peak well below maximum) the contribution of ground (wet, dense soil) would be in the same order of magnitude as freezing of water. We get about 1000kWh from ground in the critical months Dec-Feb. Wet soil delivers about 15W per square meter of that part of the interface between ground and the tank below frost depth (comparable to numbers used in sizing ground loops). I expect this to be lower for rocks due to lower specific heat, and you cannot harvest energy from freezing ground (as we saw when the ice cube touched the walls of the tank). In addition, it depends on the depth of the tank, and: the larger the tank is, the smaller the surface is in relation. So I would not overestimate the contribution.
Just to be sure to avoid one potential misunderstanding as we discuss only the tank and ground now and I had been asked similar questions elsewhere: The solar collector is not an option – it is essential to replenish the energy in the tank that should ‘just’ be a short time buffer. Otherwise, the system would not be that different from other geothermal systems: https://elkement.wordpress.com/2015/10/14/economics-of-the-solar-collector/
– The tank / cistern would be damp-proof (using a special type of concrete or pond liner or the like) and has some kind of lid, so moisture should be not be problem. But if the cistern replaces a basement underneath the building, you prevent the building from using the hear flow from ground directly, so heating demands will be a bit higher.
– Cover: It has to be insulated against cold air from above and closed tightly so that no small animals get in. If additional insulation material is needed depends on the depth the cistern.
WOW! One of the many things I respect about you is that you never do things half-way :-) A great big thank-you for those answers!
Thanks for the feedback and again for the great questions!
Lol how creative
It’s hard to try not to make sense of this poem :-)
I know what you mean. What’s even more, can you remember the posts from which the lines are taken? It was a fun read. :)
Some of them :-)
I hardly remembered some myself – Google put mainly old postings on top of its list :-)
