The biggest free market of them all is a natural ecosystem. Every human society that has ever existed is socialist by comparison.

But without nuts, it wouldn't be California.

"Today we generate more electricity from non-fossil fuel than all of electricity we used to generate just 40 years ago"

And those nonfossil sources are hydro and nuclear, compared to which all the other carbon-free sources are a rounding error. If Greenpeace were really trying to reduce carbon, it wouldn't be opposing these every chance it gets.

Everybody loved Greenpeace when it was saving whales. Then it didn't just take a turn to the left, but to the radical anti-human left. Now it reflexively opposes anything that might promote humanity, like changing fuels from fossil to nuclear if, perchance, their own climate scenario were proved true.

The left did used to be optimistic (reread your London and your Steinbeck), and that was when it was popular. Post-1970, it seems to have sunk into anti-human primitivism. Remember when a synonym for leftist was "humanist?"

Let us henceforth dub it the Snow Crash exploit.

You wouldn't use Earthly gunite on the Moon, but something more like epoxied regolith over carbon fiber mesh. The principle is the same. The article cites the possibility of large lava tubes. If those exist, there will be smaller tubes that will be early candidates for reinforcement.

This is actually another false assumption. You see the right/left reversal because you are facing the other way when viewing the reflection. That's why up/down are not swapped also.

"What I dont understand is , whats the big deal about uber? why is everyone giving it so much publicity? "

Vast press coverage accorded to a service that most people would need about once a year. Such is the scorn of rent-seekers whose gummint granted monopoly is threatened.

What I really want to see is for the Uber concept to be applied to health care. That's when the news will get really interesting.

Can we develop an e-book reader that presents a virtual image that must be focused on as though it were at a distance? Let a cohort of Asian kids go through childhood reading from this device and see what happens to their vision.

I'm a photographer, and this is a common false assumption. The actual focus is on whatever is in the mirror. It's exactly like seeing the same subject through clear glass.

Uber is responsible to global warming and the heartbreak of psoriasis in 3...2...1.

I've heard that several divisions of lawyers were ready to cross the Rhine in massed Hummers and be airdropped into major commercial centers from a fleet of Gulfstreams.

I have hiked in that very tube (about a mile long). If you had to live in a lava tube, it would be both easy to reinforce with something like shotcrete, being close to and parallel with the surface, and easy to create new entrances. It would be ideal protection from radiation.

In Arizona, the heat sink for nuclear is dry desert air, not water. This would also work in other dry parts of the world, such as Australia or Chile.
