One-Way Ticket: Mars One Project Applicants Top 100,000

voidptr Re:what happens if the chick get pregnant? (240 comments)

Fun fact: having a child on Earth also means inflicting an uncertain existence upon them including certain death. That fact doesn't appear to have stopped significant numbers of earthers from breeding either, even in conditions most of us wouldn't want to spend a day in let alone a lifetime.

TSA Orders Searches of Valet Parked Car At Airport

voidptr Re:And the story is...? (453 comments)

It's also not going to work flying in and out of New York, where handguns are prohibited for non-residents, and attempting to check it per the FAA's regulations will get you arrested for violating NYS law.

Electric Vehicles Might Not Benefit the Environment After All

voidptr Re:Efficient-market, inefficient-energy hypothesis (775 comments)

By your theory, my Model S wins. The initial purchase price of a Model S is pretty middle of the pack to comparable cars in the full size luxury sedan class.

Similarly sized and spec'd ICE vehicles to the Model S get 20 - 25 MPG. At $3.50/gallon gas, that's 14c/mile.

The Model S gets about 3 miles / kWh. At 11.5c/kWh, that's 3.8c/mile.

Even if we assume a kWh from gasoline and a kWh from the wall have similar environmental impacts, and transmission costs/losses for both are properly reflected in the price at the meter, the Model S is three and a half times more efficient at turning the delivered energy into motion.

No, the Tesla Model S Doesn't Pollute More Than an SUV

voidptr Re:Let's compare the two (559 comments)

You're the one who started with the statement you could power a gasoline engine with a renewable clean energy source, namely Hydrogen.

You can't. Hydrogen isn't an energy source, because you can't refine hydrogen into a viable fuel using just hydrogen feedstock in an energy positive process. Hydrogen/Oxygen is at best another energy storage media, with cycle losses and storage requirements that are distinctly different but not theromdynamically unlike existing battery chemistries. There's nothing "clean" or "renewable" about burning hydrogen in an ICE engine in and of itself.

No, the Tesla Model S Doesn't Pollute More Than an SUV

voidptr Re:Let's compare the two (559 comments)

The point is, hydrogen isn't any more of a fuel than lithium in a battery is. They're both just energy storage media.

Gasoline is a fuel, because I can take a barrel of oil out of the ground, consume some of it to repay the energy used to pump it out, consume some of it to refine the remainder into gasoline, and end up getting more energy out of burning the rest than I had at the beginning of the process.

There's no above-unity mechanism to get free hydrogen into a motor vehicle, certainly not one that works on any commercial scale.

No, the Tesla Model S Doesn't Pollute More Than an SUV

voidptr Re:Why the anti-electric car meme? (559 comments)

You missed two more:

Third, the people who make their living off of pumping liquified dinosaur out of the ground, turning it into gasoline and selling it to consumers.

Fourth, traditional car dealers who are (a) terrified of a direct to consumer sales channel, and (b) terrified of the fact that without 4,500 moving components in the engine and transmission alone, electric cars don't need anywhere near the maintenance required of a gasoline car, and thus more opportunities to upsell even more "services" 4 times a year. Even things like brakes don't get used up much if you're using aggressive regen most of the time to slow down.

No, the Tesla Model S Doesn't Pollute More Than an SUV

voidptr Re:Facts don't deter FUD (559 comments)

The Model S competes in price to other cars in the $80k - $100k price range to start with, if you were going to spend that much on a car anyway it's not any more expensive. And over a 3 - 5 year period, it's cheaper once you factor in the difference in fuel costs.

As for batteries, they currently have an 8 year warranty. We're learning fairly fast that what kills smaller batteries fast is heat and high states of charge, which are far less of a concern in cars where you've got thermal management systems and capacity to keep the charge around 80% most of the time.

Gasoline cars can end up with pretty expensive repair costs once you pass the 8 year / 100,000 mile mark too as engine components start to wear out. Even changing $2 gaskets gets pretty pricey when it takes 10 hours of shop time to get to it and bolt everything back together again.

voidptr Re:Let's compare the two (559 comments)

hydrogen is renewable.

Only by expending more energy to crack it off of whatever it was previously attached to than you'll get back by burning it again, at which point you may as well just shove those electrons into the battery on a Tesla anyway and save yourself the trouble of trying to transport diatomic hydrogen around.

Tesla To Blanket US With Superchargers In Two Years

voidptr Re:Open platform charging ? (311 comments)

Right now they're Tesla only. However, Tesla also has a side business selling power trains to more traditional car companies, and they're probably likely to license access to the network to those cars as well once they've built it out some.

Tesla Motors Repays $465M Government Loan 9 Years Early

voidptr Re:Electric cars are just not going to take off... (446 comments)

That's not exactly a scenario I or most other people do often enough to make it influence which car I buy. For the once a decade I need to get from NYC to LA in a day and a half, I can rent or take a plane.

Of course, the irony here is once the Supercharger network finishes building out along I-40, I may very well drive from coast to coast a few times, since the Superchargers are cheaper than airfare.

Tesla Motors Repays $465M Government Loan 9 Years Early

voidptr Re:Electric cars are just not going to take off... (446 comments)

The Model S is comparable in purchase price to an otherwise equivalent gas-powered car. It's a large, high performance luxury sedan, and other cars of that size, horsepower, and trim level run $75 - $100k as well.

N. Carolina May Ban Tesla Sales To Prevent "Unfair Competition"

voidptr Re:The best part of the article is at the bottom (555 comments)

It's fine if you want franchise laws to protect existing dealers from their manufacturers. There's nothing wrong with a guarantee that after Bob's Dodge dealership spends a decade investing in the local market that Chrysler doesn't just move in next door and undercut him.

Tesla however doesn't have any existing dealers to screw over, and making them sell through other brand's established dealers is a horrible conflict of interest. The legacy brands made their bed and need to lie in it, but they shouldn't be able to force the upstart to deal with the mess their competitors made.

Bezos Expeditions Recovers Pieces of Apollo 11 Rockets

voidptr Re:Dammit, editors! (119 comments)

He stated a year ago he was looking specifically for Apollo 11 and started with estimates of where that particular flight profile would have ended up.

It's possible this stage is from another launch with a similar ground track and they can't confirm it until they find an intact serial number, but it's likely these are Apollo 11.

Ariane 5 Has No Chance, Says Elon Musk

voidptr Re:SpaceX vs. ESA (188 comments)

Transferring fuel and oxidiser sideways between tankage sections under 3-4 gees of thrust and vibration is, as far as I am aware, going to be a first in rocketry.

The Space Shuttle would like a word. What do you think was in that big orange tank that didn't have engines on the bottom of it?

All of Nate Silver's State-Level Polling Predictions Proved True

voidptr Re:Good for him (576 comments)

You can argue the benefits and downsides of the Electoral College vs Popular vote all day long.

However, you can't retroactively the specific outcome of a race run under one set of rules as evidence for a switch. The rules of the game determine the entire strategy or the race, and thus the outcome. If both parties were campaigning for a popular vote win in 2000, the results wouldn't be the same as what they actually were with both sides going for a EC win. As long as the election is held under EC rules, the aggregate popular vote is a relatively meaningless number.

It'd be like arguing every score in football should be one point, because you just lost two field goals to a touchdown, but scored on more possessions. Maybe you should change the rules in the future, but you can't go back and rescore a game played where FGs are 3 and touchdowns are 7 and pretend the strategy and outcome of the game wouldn't have changed.

Endeavour Arrives At California Science Center

voidptr Re:Yes lets all celebrate! (57 comments)

The original post was correct, Apollo 17 was the last manned launch of a Saturn V. The Apollo half of Apollo-Soyuz went up on a Saturn IB.

Endeavour Arrives At California Science Center

voidptr Re:Yes lets all celebrate! (57 comments)

Just to be even more pedantic, since the question was "How long between the last Saturn V carried a human into space and the Shuttle first carried one?" The manned Skylab shots were done on top of a Saturn IB, not a Saturn V, since they were just to LEO. Skylab itself was boosted up on a Saturn V, but no crew.

Apple CEO Tim Cook Apologizes For Maps App, Recommends Alternatives

They didn't start from scratch. There's plenty of press that they acquired at least 2 GIS companies since 2009, and it's fairly evident that they licensed data from TomTom as well.
