Trapped inside the light cone on a path of eerie fire. Causally connected to your past . . Onward. Celestial spheres embrace the future cone gather round your burning self.
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.
In the past days different versions of an article had popped up in my social media streams again and again - claiming that you could power your home for 24 hours by cycling for one hour. Regular readers know that I craft my statements carefully in articles about energy, nearly as in the old times … Continue reading No, You Cannot ‘Power Your Home’ by One Hour of Cycling Daily
Peter von Rittinger's biography reads like a Victorian novel, and his invention was a text-book example of innovation triggered by scarcity. Born 1811, he was poor and became an orphan early. Yet he was able to study mathematics and physics as his secondary education had been financed by the Piarist Order. He also studied law … Continue reading Peter von Rittinger’s Steam Pump (AKA: The First Heat Pump)
