Your hero is an idiot and this will all end in tears
...a surfeit of orders is actually a curse in this industry, where scaling up production takes years.
This is not an Apple #2.
You're right of course, as evidenced by his other colossal failures (PayPal, SpaceX, SolarCity)
Right again. I'd have been far more confident of their success had half as many people shown serious interest in their product.
Welcome to last year:Let me know when Musk achieves his claim of launching payloads for only $500/pound. Or maybe even landing a used rocket on its fins without destroying it.
Not that I'm in the EM RDF, but rockets are expensive. If you treat them as disposable you have to subsidize their cost into your payload costs. If you could reuse them after refurbishing for a fraction of the cost of replacing them with new every time you could significantly lower your payload costs.Can you even begin to explain to me why it is so important to re-use a rocket? Not that there is any evidence that it either can be done or will be done.
Because maybe it's 2016 and time to dump the idea of throw-away rockets which has existed since the beginning of space travel over 50 years ago? If computers followed the same model, we would still be using vacuum tubes. Actually, scratch that. We would still be using mechanical relays.Can you even begin to explain to me why it is so important to re-use a rocket? Not that there is any evidence that it either can be done or will be done.
No, I'm saying <redacted for legal reasons> is a bullshit artist. Whether or not it *can* be done is beside the point - whether or not it's a good idea is an entirely different question.
Your boy isn't that much different from Donald Trump - don't let science and engineering stand in the way of a populist brain fart.

When I was a boy a very long time ago, there was a fictional character called Tom Swift. I owned at least 30 of his books; they warped my appreciation of the real world for some years. Maybe too many people were inspired by this sort of idealistic fantasy?
Emphasis mine. Yes, we're giving electric car subsidies but this is mainly to level the playing field between electric cars and gas cars. Gas cars have massive direct and indirect subsidies. Some figures I've heard thrown around are up to $5 per gallon to account for externalities and costs drivers aren't paying for at the pump. And then you have the fact here in the US car use in general is massively subsidized whether those cars are powered by batteries or gasoline. For example, NYC devotes tons of expensive land to free curbside parking, and often requires housing developers to install a mandated minimum amount of parking. This effectively raises housing costs for everyone whether they own a car or not, and makes it much less expensive to own a car in an environment where private autos arguably cause more harm than good. Without these massive subsidies, my educated guess is car use/ownership would be mainly a province of the upper classes. So anyway, let's not kid ourselves that the big three aren't beneficiaries of massive government subsidies. Who bailed out the auto industry after 2008?Tesla: Profitable (in the same way the other US automakers are, with subsidies).
As much as I hate say it, in a race between him and Hitlery he's the better choice. I actually can get behind some of his ideas on dealing with terrorists as well. What we've done hasn't been all that effective.Your boy isn't that much different from Donald Trump - don't let science and engineering stand in the way of a populist brain fart.
Never mind Tesla, the companies that are going to sell a lot of electric cars are the ones with the really big R&D budgets. And that's not Tesla. It's BMW. It's Toyota. It's Mercedes-Benz. Tesla will do OK right up until electric cars become the norm. Then companies like BMW will cream them.
It depends whether you need high or low thrust. If you're getting to LEO, you need high thrust, and nuclear rockets deliver roughly twice the specific impulse of chemical ones. Once you're out of Earth's gravity well, you use much lower thrust but a nuclear rocket can supply that thrust for years. For example, you have the VASIMR which in theory can give you a specific impulse of ten times or more that of chemical rockets. It's worth noting also once you're in space, you have a very rarified mixture of gases, mostly hydrogen, which you can scoop up, heat in a nuclear reactor, and use as propellant.The fantasy of using nuclear powered rockets is just that - fantasy.
The key issue is reaction mass. Heating that mass up to create pressure and thus accelleration is not the problem. You can get plenty of heat with ordinary (non-radioactive) chemicals such as hydrogen and oxygen. You can't use much more heat because the materials to confine it are too difficult.
The problem is carring enough reaction mass, and the extra weight of a reactor doesn't help. In fact, it hinders.
Yes. Once the major automakers take electric cars seriously, meaning that such cars comprise the majority of their production, Tesla will be screwed by simple economies of scale. You can't hand assemble battery packs made from thousands of 18650 size cells and be competitive when EVs hit critical mass. Frankly I don't know why he went this route in the first place. I expect EVs to reach this critical mass in the next few years, perhaps sooner if gas prices tick up again. People were already burned the last time gas prices went up. I suspect many will say they've had it the second time around, and beg/plead for electrics. If it turns out a major automaker (I'm actually betting on one from China) comes out with a decent electric for the same or less than a gas car, it's game over for gas cars, and game over for Tesla outside of the luxury niche. At that point it won't matter if the subsidy exists or not.Never mind Tesla, the companies that are going to sell a lot of electric cars are the ones with the really big R&D budgets. And that's not Tesla. It's BMW. It's Toyota. It's Mercedes-Benz. Tesla will do OK right up until electric cars become the norm. Then companies like BMW will cream them.

Licensing Tesla IP might actually be the better route for them. They could continue to do what they're relatively good at, namely produce relatively low volumes catering to niche markets, and let the big boys make EVs for the masses. They won't have much competition in their niche, plus they'll have a second, potentially very lucrative source of income.
Makes sense to me. Along the lines of forcing the market, I'm not aware of Tesla actively meeting with legislators with the idea of creating captive markets for EVs. For example, if large cities like New York decided to convert city owned or regulated fleets (i.e. taxis, buses, garbage trucks) to electric in the near term, and require all vehicles operated within their limits to be zero emissions in the medium term (5 to 7 years) that could get us to critical mass in EV production. In my opinion the automakers have been moving at a glacial pace. We had the EV1 back in the early 1990s which was actually not bad. We should have built on this. If we had, it may well be the only place you would be able to see a gas car now would be in a museum or vintage car show.Though Elon has said specifically that their goal is to force the market to react to their actions and accelerate an EV future. Much like Google has done in internet connectivity (Google Fiber) and cellular plans (Google Fi). This requires them to hake something at least as cheap as the 3. I suspect that once everyone else gets on board Tesla will retreat to the $100k+ market where their scale is enough to remain competitive.
Did time's account get hacked by Prof.Wizard? Pretty entertaining argument.

The landing reminds me of those old sci-fi movies from the 1950s where the rocketship lands on its tail on some alien planet. Next, they need to build a flying saucer. That would be less of a problem keeping up when landing.
Complicated doesn't mean stupid. Trying to land on a ship might not be ideal, but it's way better than just giving up and trashing a rocket that doesn't have enough fuel to make the trip back to land on solid ground.Yes, but they landed on land of course. Landing on a boat is particularly stupid.
