  1. ​ @acollierastro  Aerospace engineer here. FANTASTIC to see someone with a functioning brain take to these clowns. I actually work in industrial control systems which is basically sensors connected to computers and then running stuff in real time. So I've done a lot of automation and a fair chunk of robotics across a variety of industries and the reliance of Tech CEOs on the ignorance of the media and the general population is staggering. I love your line "What do you mean?" because that catches so many of these clowns out. From self driving cars to robots that think I have seen so much BS in recent years its mind numbing. Some of the claims about going to Mars and setting up colonies and terraforming are laughable. When I was an undergrad back in the late 80s we had an Alum who worked at NASA explain why terraforming was complete bunk. He'd just done a project for NASA on it and their conclusion was "Forget about it." I can tell you from knowing the basic concepts which haven't changed that these claims we can geo-engineer our way out of climate change is even more bunk. If you want I'd be happy to explain some of these things and how bad people understand some of these sci-fi fantasy claims. You're an astrophysicist and I'm certain you can understand some basic concepts like volume, mass and basic thermodynamics. Once you apply some basic geometry you suddenly realise just how ridiculous some of the claims are. Here's a couple of simple ones: How much does a cubic kilometer of air weigh? How much energy does it take to raise the temperature of a cubic kilometer of air from 20C to 21C? How many cubic kilometers are their in the first 2km above sea level? How much energy does it take to raise that much air from 20C to 21C? Right now there's about 3.5 Trillion tons of excess Carbon Dioxide int he atmosphere most of it fairly close to the earths surface. Its mostly in that first 2km above sea level. How do you: 1) Process that much volume? 2) How much energy will it take to suck that much air into a machine, extract the CO2 and then put that CO2 into a form that we can bury? There just the sorts of dumb questions engineers ask.
