Welcome to c/science_memes @ Mander.xyz!

A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules

  1. Don't throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

This is a science community. We use the Dawkins definition of meme.

Yes but no. The two actual uses of carbon capture is to remove the co2 from the air before it would happen naturally and the other is making fuel sustainable for retro or novelty vehicles. You dont have to stop selling gas cars if all the fuel they use is made with carbon capture. This makes the fuel more expensive but more sustainable. Once you have driven a 911 or skyline you will understand why someone would want to drive a gas car ;) Also, technically you are going from a higher energy fuel to lower energy so as long as you can do something with the co2 it abides by thermodynamics but the problems arise when you consider real world losses.

TLDR: carbon capture is a technology we should use after we stopped polluting to fix the earth.

Yeah, it would just give people a blank check to use more fossil fuels. It is kinda like a diabetic person who acquired the disease later in life, and still not adjusting their lifestyle because drugs mitigate the effects anyhow. And the person will keep eating unhealthy food or not exercising.

Pointless. The gas should be used for things that actually need it like airlines.

Trains go choo choo. But yeah that as well. On long haul flights that cant be avoided that is an excellent use for carbon capture fuel.

Specifically it's not trying to be an over unity machine. Energy is spent pushing air through the filter medium; energy is spent moving the filter to the CO2 extractor; energy is spent heating the filter (or whatever the extraction system is); energy is spent compressing or freezing CO2 for storage
