I found an incredibly detailed research report by the Australian government – about energy use in private homes, by appliance and purpose. It confirms my reluctance to 'predict' cooling energy as usage of air conditioning depends strongly on life-style choices.
In a recent post I showed these results of simulations for our heat pump system: I focused on the technical details - this post will be more philosophical. What is a 'simulation' - opposed to simplified calculations of monthly or yearly average temperatures or energies? The latter are provided by tools used by governmental agencies … Continue reading Simulations: Levels of Consciousness
Don't worry, The Subversive Elkement will publish the usual silly summer posting soon! Now am just tying up loose ends. In the next months I will keep writing about heat transport: Detailed simulations versus maverick's rules of thumb, numerical solutions versus insights from the few things you can solve analytically, and applications to our heat … Continue reading Heat Transport: What I Wrote So Far.
This year ice in the tank was finally melted between March 5 to March 10 - as 'visual inspection' showed. Level sensor Mr. Bubble was confused during the melting phase; thus it was an interesting exercise to compare simulations to measurements. Simulations use the measured ambient temperature and solar radiation as an input, data points … Continue reading Simulating Peak Ice
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, … Continue reading Ice Storage Hierarchy of Needs
Nearly all of renewable energy exploited today is, in a sense, solar energy. Photovoltaic cells convert solar radiation into electricity, solar thermal collectors heat hot water. Plants need solar power for photosynthesis, for 'creating biomass'. The motion of water and air is influenced by the forces caused by the earth's rotation, but by temperature gradients … Continue reading Temperature Waves and Geothermal Energy
I have become obsessed with comparing climate data for different regions in the world and in different years (space + time). Finally I have found the tool I was looking for; now I can compare average Ice Days quickly - days with a maximum temperature < 0°C. In the first quarter of 2014 there were: 5 … Continue reading More Ice? Exploring Spacetime of Climate and Weather.
