Shooting two guns at the same time does in fact look cool. That’s not a myth. Hitting two targets with two guns at the same time is really hard though.

Nowhere did I say or imply that capturing CO2 is a net positive of energy. It is in fact a huge energy sink. If you aren’t using renewables to power CO2 capture then you’re just making the problem worse.

We have to do both. If today our emissions went to zero we would still see more warming because of all that CO2 we’ve already released. First priority is to get to net zero so we can stop making the problem worse, then we have to remove all the CO2 we released. We have the technology now to do step one it’s just a matter of scaling it up. While we work on step one we need to do the research on the best way to do step two so when we get to that point we have something ready to go. Pulling CO2 out of the air is going to be inefficient no matter what just from the physics of the problem but it still needs to be done and the energy to do so has to come from renewables.

Doing some back of the envelope calculations we have put about 1.6 trillion tons of CO2 into the atmosphere since the industrial revolution. Latest estimates put the number of trees on earth at around 3 trillion. Looking at how much CO2 a tree takes up puts the average around 600lbs over the first twenty years. So combing all this if we want to plant enough trees to take up all the excess CO2 we would need about 5.3 trillion more trees, or almost double the total number of trees on the planet.

This is simply not achievable in a fast enough time span to make a difference. Nevermind that I was being super optimistic with all my calculations and the real number needed is likely much higher still.

It is simply a necessity to develop better methods to pull CO2 directly from the air and to do it on the same scale that we have been releasing CO2.

Are the predicted prices ever crazy far off from what they actually end up being like what happened in Texas last winter? Where am outage causes price to go from like 20c/khw to 2000c/khw over a one hour period?

How do you keep up with the current price? Does your thermostat have a setting where if the price is above X then turn off? Do you just come home to a freezing house and say “oh the electric is too expensive, guess I’ll grab some wood”?

Given the egotistical nature of the Goauld I wouldn’t put it past them to have a sort of “gentleman’s agreement” to keep war mostly ground based to help limit the ability of the jaffa to rebel. We never see any Goauld weaponry that can track its target for instance. Everything just shoots in a straight line until it hits something. They want “war” to be up close and messy to help control their subjects. Given that, air defense as we understand it would defeat the purpose of fighting in the first place for them.

My understanding is that valve says publishers can’t sell their games steam keys cheaper on other platforms but can charge whatever they want if steam is not the one providing the download. Network infrastructure isn’t free and if steam is the one actually facilitating the download they get to take their share.

Thanks for the write up. I was thinking about getting part one a while ago but the negative reviews scared me off. That part 2 is past it’s release date with no communication doesn’t inspire confidence.
