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 […]

Cooling Potential

I had an interesting discussion about the cooling potential of our heat pump system – in a climate warmer than ours. Recently I’ve shown data for the past heating season, including also passive cooling performance: After the heating season, tank temperature is limited to 10°C as long as possible – the collector is bypassed in […]

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 […]

Ice Storage Hierarchy of Needs

Data Kraken – the tentacled tangled pieces of software for data analysis – has a secret theoretical sibling, an older one: Before we built our heat source from a cellar, I developed numerical simulations of the future heat pump system. Today this simulation tool comprises e.g. a model of our control system, real-live weather data, […]

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 […]
