No, wee think we know how to efficiently search for other technological life even if we technically can't do it yet. Someone else could do the same to find us. The fact that they apparently haven't suggests that they are not there to try.
This isn't certain, as there are other possibilities, but this is the most likely one.
Fermi's paradox is telling us something, just not a lot. There is probably no other expansive, technological civilization in the Local Group. That has always looked most likely and it probably always will.
Sure, but if you claim batteries are the demand you look like you're ignorant. Also, if the neodymium gets too expensive you can always switch back to older technologies.
Neodymium is used in NiMH batteries, which are on the way out. Lithium batteries don't use it.
Lithium in lithium ion batteries doesn't explode. That's usually the electrolyte, although if you overcharge them you can get reactive lithium to plate out.
So, if I sell aspirin and put a big label on the box, saying "this is not heroin", I could be in jail for one to two years? If that's true then the justice system is really messed up.
Depends on the type of geo-engineering you're talking about.
Albedo management works for temperature, but does nothing about the acidification of the oceans. The type that may work involves removing carbon dioxide from the air, like ocean iron fertilization, burning biomass with carbon capture, or enhanced rock weathering. They all need more research.
That 25% margin is just what Tesla claims. It takes no great insight to arrive at.
Tesla computes gross margin differently than other auto makers. I'm not saying one is more correct than the others, but Tesla would barely squeak by on what to others would be a comfortable margin.
If they are storing lithium ions in titanium niobium oxide, then that implies to me that they need the whole anode to have niobium, not just the surface. The surface might work for charge rate but not for energy storage.
I believe the solution Musk is proposing would also include large lithium-ion batteries, which when damaged can short and ignite the highly reactive lithium.
There is no metallic lithium in a properly functioning lithium ion battery. The big problem is generally the flammable electrolyte.
Anyone with a modern 2010 or later house built to hurricane standards and a Tesla solar roof and Tesla storage batteries, by definition, has full power.
That's assuming you still have a roof. Even if you do, I'm dubious that the solar cells would still work.
I wasn't exactly complaining. As I said, everything has its downsides. Making concrete releases carbon dioxide, so finding a replacement eventually is important. It also clutters up old sites and once a company goes bankrupt there's no one to clean them up. I'm in no particular hurry, though.
According to NextEra, 800 tons of concrete per windmill. A quick look shows ranges from 200 tons to 1000 tons per windmill. I'd call that gobs. Their are a lot of abandoned wind farms that no one wants to clean up, too. A clean-up deposit should be required to build them.
I don't know what cows care about, but if you can't build near it the value of the land will decrease. Maybe a little, maybe a lot.
You can't have people living near a windmill, so that may cut down the value of the land. Also, huge gobs of concrete are used to stabilize them. Well, everything has some negative consequences, it's all a matter of what you prefer.

You should be able to tell that Earth is life-bearing from far off. Why didn't they come, or send robots, and check us out?

Aluminum can be substituted for copper.

Tesla, or rather Panasonic, is leading the way in using low cobalt cathodes. I don't see this as a long term problem.

The satellites are nearly in polar orbits. South of Vandenberg is ocean, as it is to the west.
That's not what he said. He said 2-3 orders of magnitude cheaper, which is 1/100 to 1/1000 times the cost.
Perhaps so, but these thorium reactors are not fast breeders. I think they are, techinically, slow breeders.

Putting down a deposit on future trucks doesn't seem in character for Walmart. Maybe they are so large Tesla didn't require it?
Ouch! That's terrible!

Both weight and volume are important, but if I had to chose one I'd say volume is more important for cars.
All true, but no matter how rare it is niobium is not classified as a rare earth.
It's not the zero G that's a problem, it's the lack of oxygen. I'd be surprised at a mutation that lets us get by without air!
The problem is that the Ringworld was rigid, which was necessary to spin it fast enough keep the atmosphere in. An airtight cylinder should work fine.
