Sources of Heat, Life, and Everything

Same procedure as every summer: Science and tech blogging comes to a halt, and the daring 'internet artist' is summoned. But also unorthodox avant-garde art is rooted in down-to-earth engineering. In summer elkement leaves the programmer's cave (a bit) and sees the sun. The local elkemental microcosmos is a fully functional biosphere-2-like ecosystem with lots … Continue reading Sources of Heat, Life, and Everything

The Heat Source Paradox

It is not a paradox - it is a straight-forward relation between a heat pump system's key data: The lower a heat pump's performance factor is, the smaller the source can be built. I would not write this post, hadn't I found a version of this statement with a positive twistย  used in an advert! … Continue reading The Heat Source Paradox

The Collector Size Paradox

Collector harvest does not change much if we only use half the collector. Perhaps counter-intuitive but explained by the characteristics of heat exchangers connected in series: Especially if one of the heat exchangers (in the tank or collector) is already much superior to the other one, it does not help to optimize the good one further.

Where to Find What?

I have confessed on this blog that I have Mr. Monk DVDs for a reason. We like to categorize, tag, painstakingly re-organize, and re-use. This is reflected in our Innovations in Agriculture ... ... as well as in my periodical Raking The Virtual Zen Garden: Updating collections of web resources, especially those related to the … Continue reading Where to Find What?

Frozen Herbs and Latent Energy Storage

... having studied one subject, we immediately have a great deal of direct and precise knowledge ... of another. --Richard Feynman Feynman referred to different phenomena that can be described by equations of the same appearance: Learning how to calculate the distribution of electrical charges gives you the skills to simulate also the flow of … Continue reading Frozen Herbs and Latent Energy Storage

How Does It Work? (The Heat Pump System, That Is)

Over the holidays I stayed away from social media, read quantum physics textbooks instead, and The Chief Engineer and I mulled over the fundamental questions of life, the universe and everything. Such as: How to explain our heat pump system? An astute reader suggested to create an 'animation' of the gradual evolution of the system's … Continue reading How Does It Work?
