I think biomanufacturing of protein via bacteria/algae could be the cheapest. For example there's even a company, prottero, making sugar via bacteria at 1/3 of the cost of sugar cane.

And theoretically with those of methods , you might be able to feed the world from an area the size of new jersey.

Feeding the world isn't the issue -

1) The world being able to afford it's food is the issue.

2) getting food to people in time without spoilage is the issue.

Minimizing the environmental impact of farming isn't an issue?
