Heat Pumps and Renewable Energy

(elkement. Last changed: 2017-02-27. Created: 2015-08-17. Tags: Engineering, Technology, Heat Pump, Energy. German Version.)

I play with control systems, software, and heat pumps at punktwissen, as a Consulting Engineer. Since a few years I have tried to explain on my blog how our 'ice storage' heat pump system works and how we log and analyze measurement data.

This Tech category here should rather be dedicated to special aspects of my professional services. For examply, I want to reflect on my personal usage of technology (and IT), and trade-offs between pragmatic use of technology and exploring science to satiate curiosity. Or on my personal view of the connection between IT and tangible technology. The latest article published Jan. 2017 is the first attempt at presenting my thoughts on technology in this way.

History: I have used 'articles' here to compile lists and links, and I have assigned some older articles about life as a techie to this category.

Solar collector, an essential part of our heat pump system.

You can turn into your own cliché. In a self-consistent way - absolutely, positively.

Some years ago I would have described myself as a nerd, geek and tech freak. I like Dilbert-style humor, worked at strange hours and found some aspect of Star Trek like adventures.
