Given the very recent rise in temperatures around here, I thought it would be a good idea to go outside and inspect my geothermal heating system. At the heart of the system is the geothermal heat pump, and a critical component of that heat pump is the core element:
Well, yes, it does look like a patch of old snow, doesn't it? That might very well be the case, but today, it's been re-purposed as a geothermal heat pump, the nature of which is to provide a sustainable source of thermal energy for heating and cooling (in this case, cooling). You can see the delicate core element right in the very center in the photo above.
Next, I firmly, but gently, grasped the core element with my hand, and slowly extracted it from the geothermal pump. It seems like, overall, it's in pretty good condition:
I then brought it inside the house and sat it down at my desk while I continued to blog (about this very same topic, no less). Then removed the end cap and inspected the core's contents. I am happy to report that this experiment in sustainable energy use has gone remarkably well: My goals for adequate refrigeration have been achieved, with negligible (near-zero) impact on the earth's resources.
And now, it's time for a poem:
A Patch of Old Snow
There's a patch of old snow in a corner
That I should have guessed
Was a blow-away paper the rain
Had brought to rest.
It is speckled with grime as if
Small print overspread it,
The news of a day I've forgotten --
If I ever read it.
-- Robert Frost
Have a great weekend, and Happy Valentines Day to all my sweethearts out there! :-)
