Solar-to-Fuel System Recycles CO2 to Make Ethanol and Ethylene - Berkeley Lab advance is first demonstration of efficient, light-powered production of fuel via artificial photosynthesis

Y'all are using different definitions of cost (so talking past each other) and a solar panel isn't a mortgage ahhh I'm ripping out my hair.

edit: note that even with an infinite lifetime, your opportunity cost is still the interest payment, forever, since instead of buying a solar panel with that money, you could lend it to someone and receive interest on it.

If they don't go bankrupt and if there was literally no cost in searching for investment opportunities. And you can't apply for a fucking mortgage and then lend the money to other people because a mortgage means you're the one being lent money that requires repayment which makes ACTUAL RETURN ONLY THE AMOUNT YOU CAN EARN OVER YOUR STATED NECESSARY REPAYMENT (straight-up shit all oh my god, or the bank would lend them the money instead of you kill me now).

If you read a guide or attended a seminar urging you to take out a mortgage to invest in something I cannot stress to you how much you really should absolutely definitely not do that.
