that Big Oil, Big Coal, etc., won't allow it. They've paid good money for the best government they can buy, after all, and that government is dead set against giving solar, wind, etc., any sort of break. It will remain that way until the Big Boys decide to get into that business themselves or find a way to make money off it somehow.

"The general welfare" provision of US Constitution no longer applies. No profit in it.

I wish I knew the answer.

These could feed every person on the planet and release billions of acres of land back to Nature.

the Earth only has 57 million square miles of land (that's 36.48 billion acres; there are 640 acres per square mile).
However, there are only 12 million square miles (7.68 billion acres) of arable land.

And people could build these in non-arable land too. But you could have looked it up without much problem too but maybe it's more important to try to stump me.

Your concept is to transfer at least 25% of our agriculture indoors.

This type of agriculture can be used to feed the world's population. How many people live in non-arable land where there is no water? People tend to live where they can actually live you know.

It was the same problem with ethanol from corn. When the margin is negative or only slightly positive, what's the point?
