Keywords: Optimal Control, Bellman. I'm serious. For a first exercise, forget Dijkstra and just solve a maze by doing Value Iteration, and plot the cost-to-go at each step. Then co…

What people normally call "CCS" is mostly a short-term hack to keep the coal mines running. If you're going to burn coal, then, yes, please do CCS, but pretty soon you need to stop…

An interesting theoretical calculation is the rate of entropy production due simply to mixing of smokestack gasses (high partial pressure of CO2) with atmosphere (low partial press…

This discussion of heat pumps makes me want to add that we may also ignore cogeneration too much. We just don't think about heat flows and temperature enough. There is, of course, …

Let's do the thermodynamics: First, some enthalpies of formation (at 298 K and 1 atm, in kJ/mol) (from [1] unless otherwise indicated): H2O(l) -285.8 CO2(g) -393.509 CO2(aq) -419.2…

I'm curious about this cartridge idea. I'm picturing a pipe with quicklime inside and coffee filters on the ends, with a blower to force air through. How tightly would the contents…

Once you have the carbon in biomass, what do you do with it? Dry it out and heat it enough to make biochar?
