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
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 twist used in an advert! … Continue reading The Heat Source 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.
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?
... 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
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? (The Heat Pump System, That Is)
