tarmol··on Terraformer Mark One – cheap natural gas from sunlight and air
I have been thinking along the same lines (same process for CO2 capture and natural gas as output). The thing that kills it is energy requirements, in this scenario 1 MW of solar panels would cost about 1 million USD + 100k USD for the plant. In theory it could be profitable within 7-8 years - possibly sooner if built in Africa or some other country with infinite solar (just napkin math).

Another thing that might make it more profitable is extra conversion to SAF (Sustainable Aviation Fuel).

Long term in this type of tech is crucial to stop burning up carbon stored in the ground for use cases that require more energy density (like flight).

tarmol··on Ask HN: GPT4 Broke Me
I am a bit concerned too, the current state of tech is nowhere near to replace a senior engineer, but where it will be 5 years from now is a scary thought.

Yesterday I tried to get GPT4 to generate me a Dovecot Sieve filter to move .ru email to Junk and mark it seen, it failed 3 times and hallucinated some syntax that looked plausible, but actually is not supported by Dovecot. My hope was that I would not have to spend 15 minutes Googling and could get an answer faster from GP4, but in this case GPT4 did not succeed.
