    every solution engineers a greater problem. Solving horse poop with cars -> Climate change

    This study doesn't correct for baseline exponential decay due to inflation, to better highlight the meaningful variations. By comparing based on 1914 dollars it also causes old var…

    First guess (may be wrong) is to manage thermal expansion/contraction constantly on a micro-scale.

    There are a lot of posts here pushing batteries. Batteries are an expensive solution that doesn't scale well at the grid level. It is useful for grid stability (fast frequency resp…

    Please look at: https://app.electricitymaps.com/map/zone/CN/72h/hourly China is heavily reliant on coal. The US Grid is presently less carbon intensive than the Chinese grid.

    This is an insane suggestion if you had a concept for how expensive batteries are and the scale of flexibility issues on the european grid. It also does nothing to help transmissio…

    Batteries don't provide meaningful flexibility on a continental scale. They're useful in localised frequency control or microgrid flexibility. An exercise to the reader, calculate …

    This is confidently incorrect. Gas power generation is a necessary evil to balance out the variability of intermittent energy generation (i.e. wind and solar). Hydropower isn't a f…

    Is 2 a number? Is 4 a number? Is 4/2 a number? Is 3 a number? Is 3/2 a number? etc... All of these symbols represent precise points on the numberline. Pi also represents a precise …

    This is well written and an interesting read but, embedding notebooks into your data pipelines smells horrible.

    You can google "system inertia" as a starting point.

    I came to the exact same solution. My feel for this type of puzzle is that there is a 'gravity' from the higher to lower value integers. So you want to help integers flow from the …
