And that was a poke at Silly Valley's tendency to see private funding and companies as solution to all of its woes (Sidecar, Avego, et al) ;)

In case it wasn't clear, I was voicing my doubt that any company would actually build such a line for $6B claimed by Musk, not an opinion that it was unduly expensive.

The capacity of the proposed system at 28-person capsules every 30 seconds is 3360 pph at peak. Three thousand more people per hour would crush the Bay Bridge?

The longest TGV and Shinkansen consists are around 400 m, so they pass a given point in 30 seconds at about 50 km/h (30 mph). Of course there's spacing for safety and so on, but 50 km/h is so low that it's really a facto

The parent was me. I like maglev but it's hard to deny that as a mainstream transportation method it was completely trounced for the first 30 years of its existence by more traditional methods. If California ditches its HSR plans for h

And if someone would like a long-distance example, at its busiest the line between Tokyo and Osaka sees up to thirteen trains per hour each capable of carrying around 1300 people.

Sure, I'd grant Oakland. The line is shown ending roughly near Bay Fair station, an 18 minute BART ride from central Oakland, but perhaps that's still a good compromise. And North Valley? People in this comments thread were saying

No, indeed I haven't. I take it you will consider a 30 km line built 40 years after the idea was first conceptualized to be a success for Musk's technology as well? Should do a lot to relieve the I-5, certainly!

It's got three short (1 km, 9 km, 30 km) deployments around 40 years after work first started. Are you saying that's the kind of deployment record Musk would like to see for his wundertechnology?

So what you're saying is that their pensions aren't "200-300K/year"?

A logical outcome of the combination of private companies owning the railways and the government's willingness to build a lot of road capacity for passenger use.

So who will be the first to offer a signed contract to build the SF-LA line for $6,000,000,000.00? Maybe A16Z will be interested in providing venture funding.

So we're all rooting for hyperloop to have test tracks in 2015, demo tracks in 2020, very limited real-life deployment in 2040, and sure to become inter-city mainstream reality sometime later? Some think we'll be on Mars by then ;

Sounds vaguely like maglev a couple of decades ago. It too was a neat idea on paper.

Link describes one-time payouts upon retirement, not recurring pensions. "Denson also earned $407,908 in total wages in 2011, according to city data, making him the highest paid city worker in 2011. Of this sum, $212,738 consisted of &

The 5000th doesn't help the person who paid for the first one. That would be the State of California in this case. Unless Mr. Musk would be willing to sign a contract for expected-10th-implementation-cost and not a dollar more?

From the pictures it looks like able-bodied passengers don't sit upright, so a person in a wheelchair wouldn't fit. Perhaps they could be helped into a seat and then helped out, though. Serious question BTW, I'm not sure what

Curves are also specced for 0.5g. That will account for quite a bit more of the total acceleration time than just speeding up and slowing down.

Doesn't mean building the first one should be expected to be easy.

Given ADA, would it be even legal for the California government to build this instead of a classic HSR? It's not even about claustrophobics, people in wheelchairs couldn't be serviced at all and obese people would be trouble too.

Oh, triple unfold is a little more reasonable. Still, the 10-20 W was fairly optimistic; you might get the 20 W with a good panel with the laptop closed and the lid flat in noon sun. With the unfold it'd be enough power to charge and r

Joey has his whole house wired to a PV setup. Not really the same thing as mounting one on the back of a laptop: for one, you can make the panel bigger and thus get more energy quite easily. Having just the surface area of the laptop constr
