How long does it take to build a reactor: 15-25 yrs each
Main component of construction: Concrete, a major contributor to CO2 emissions
How many would we need to produce the energy required to run carbon capture infrastructure: ~1500
For your alternative, it has more merits but the main drawbacks come down to where do you grow it, and how does that effect the environment around it. Growing a shitton of kelp is going to create problems with nutrition in that area. I like this method most but the scalability is still a major problem. The amount you would need to grow is STAGGERING. I don’t know how we could do that and still have any coastal sea left open. Maybe massive floating barges in the open ocean.

It only takes that much time and cost in the West, because we killed nuclear with regulations.
Look how many reactors China is building.
I refuse to take anyone seriously that spouts this level of ignorance on technological matters.
