Gary beat me to it. Yes, food to fuel seems like a poor approach. But sewage + seawater + sunshine to sugar via algae, then to alcohol via yeast, that’s a biofuel too. (With several ancillary benefits to humans and environment).https://twitter.com/garycdavison/status/1094452337844908038 …

I'm totally fine with biofuels, and against corn ethanol as a fuel (because it's inefficient), but why exactly is "sun -> X -> fuel" good, but "sun -> food -> fuel" bad? (srs question)

In theory it doesn’t have to be if everyone is getting enough of an adequate diet. In practice most of the other food to fuel stuff has turned out to be comparably inefficient to corn—>ethanol. So it’s just not a very good bin to look in

There’s also a social esthetic argument about the priority it communicates. That one doesn’t particularly interest me; when it comes to people eating and staying warm I prefer the engineer trying to solve it to the poet trying to empathize. But that is more personal style...

> esthetic ... doesn't interest me I'm like that, except to point of parody (in my defense, I plead autism, your honor). Anyway, seems like we agree on the topic. Thx. Back to work!
