literally the least efficient in terms of cost and time.
battery backed renewables are a fraction of the price and are being deployed right now.

edit: the tech is cool as hell. go nuts on research reactors. nuclear medicine has saved my sisters life twice.... but i'm sorry, its just not a sane solution to the climate crisis.
my best stays have been apartments... my worst stays have been in apartments.
you kinda dont know wtf you are going to get, especially on airbnb where the reviews are bs folksiness "the host is amazing, thank you so much" garbage. reviews on booking.com are much more reliable and brutally honest.
hotels maybe meh, but they are far more reliable and you have a better idea of what you are getting. a "serviced apartment" is ideal, but often $$$.
i very much understand that airbnb's sterilise communities and drive up rents. taxing the fuck out of them would remove a lot of the slum lord garbage from the market but keep the option there for ppl really want that.
