His comments at the Code Conference on May 31 via Recode.net:
Bezos says tasks that require lots of energy shouldn't be handled on Earth. Instead, we should perform them in space, and that will happen within the next few hundred years."Energy is limited here. In at least a few hundred years ... all of our heavy industry will be moved off-planet," Bezos added. "Earth will be zoned residential and light industrial.
You shouldn't be doing heavy energy on earth. We can build gigantic chip factories in space." Solar energy, for instance, is more practical for factories in space, he said.
"We don't have to actually build them here," he said. "The Earth shades itself, [whereas] in space you can get solar power 24/7. ... The problem with other planets ... people will visit Mars, and we will settle Mars, and people should because it's cool, but for heavy industry, I would actually put it in space."
No word yet, however, on when Bezos plans to move Amazon fulfillment warehouses beyond the surly bonds of Earth.
