Electric cars (the ones you can get right now) are terrible when it is really cold or really hot.

Really? Were you aware that Norway is one of Tesla's best customers. I think Norway is a cold country? Here is blog about someone's trip across the US in winter. Here is a video of a Tesla P85D passing pulled over SUV's after a bad snowstorm. I don't see any blankets.

Oh, and Californians buy many Tesla cars. California is kind of hot, isn't it?

Submission + - Inexpensive Electric Cars May Arrive Sooner Than You Think

catchblue22 writes: According to an article in MIT Technology Review, a new peer reviewed study suggests that battery-powered vehicles are close to being cost-effective for most people:

Electric cars may seem like a niche product that only wealthy people can afford, but a new analysis suggests that they may be close to competing with or even beating gas cars on cost. The authors of the new study concluded that the battery packs used by market-leading EV manufacturers like Tesla and Nissan cost as little as $300 per kilowatt-hour of energy in 2014. That’s lower than the most optimistic published projections for 2015, and even below the average published projection for 2020. The authors found that batteries appear on track to reach $230 per kilowatt-hour by 2018. The authors found that batteries appear on track to reach $230 per kilowatt-hour by 2018. If that’s true, it would push EVs across a meaningful threshold.

To my mind, the difference is clear. It's Lucas.

I agree. I felt so sorry for Natalie Portman in Episode III. "Oh Ani! YOU'RE BREAKING MY HEART!" Seriously. I cringe. That is no one but the director.

Watch Natalie Portman in Black Swan. She is utterly brilliant.

Not that I hate Star Wars. Far from it. The broad story arcs echo many ancient myths and stories. George Lucas has said that he read Joseph Campbell's "Hero with a Thousand Faces" which surveys many ancient myths for commonality. The idea of a young boy escaping his mundane life to find his "hero's journey" is primal, as is the story of a son of facing the sins of his father. In my mind these things elevate Star Wars into the pantheon of cinema, in spite of the horrific dialog.

But you know what? Every article, every boycott and every protest is pushing them back. Similar bills are stalling or failing. The outrage at actions like these are causing more and more Americans to leave their religion in disgust. The more we drag this bullshit into the light, the more the theocrats feel the heat.

Fair enough, but what scares me is how many extremists are already in power, in Congress and in the Senate. And on the road to the White House. We as a society really do need to take a close look at what is known as the "christian dominionist movement". This movement seeks to establish an American theocracy with the rule of law given by the bible. We should think about what these people are actually proposing: the death penalty for abortion, both for doctor and mother. The death penalty for homosexuality. Here is an article to give you an idea of what I am talking about. A very good read on this subject is American Fascists.

It is easy to dismiss these people as being a crazy fringe. Indeed every society has its own lunatics. What is concerning is how this extreme form of christianity has infiltrated the main stream of christianity and what we commonly know as the christian right. What is extremely concerning is how many mainstream politicians share similar modes of thought to this movement. When I hear about laws such as what Tim Cook is writing about, I hear the clicking of a ratchet, bringing us a small step towards an American version of the taliban government.

Those of us with a sense of what is actually going on must work towards steering our society away from this cliff. Above all, we should promote the idea that although we live in a tolerant nation, we should never tolerate intolerance. The bastards who bring in laws like this should be run out of town.

She can follow up on her work at HP and merge the Democrat and Republican parties together. That should make things much more efficient, increase shareholder value and offer synergies to enhance international competition.

Or she can sell off the US government's core technological assets and turn America into a hollow corporate brand name that creates almost nothing. Just like she did with HP when she sold off HP's advanced technology division as Agilent, and changed HP from a technological powerhouse into a brand-name for shitty computers and components.

I remember how Bill Gates never thought that the Internet would ever take off. Also Edison thought we'd all live in pour-in-place concrete....

Yeah well, I don't think that Bill Gates is a genius. According to this interesting perspective,

What really made him rich was having been in the right place at the right time in 1981 when IBM needed an operating system for its new PC. Gates (with Allen) borrowed heavily, to put it gently, from an existing operating system, Digital Research’s CP/M. (For DR’s version of this history—“Microsoft paid Seattle Software Works for an unauthorized clone of CP/M, and Microsoft licensed this clone to IBM”—see here. A less biased, though still damning, look is here.) In other words, another instance of adopting someone else’s work and taking credit for it—this time with the innovation of litigating aggressively and manipulating markets to defend a monopoly position. Because once it secured that monopoly, Microsoft did everything it could to crush competition.

And Edison was rather similar. Edison used brute force discovery to solve the light-bulb filament problem, and used some, shall we say agressive business tactics to protect his business. In order to make people afraid of his competition (alternating current, Westinghouse), he used AC to electrocute animals such as elephants. He successfully campaigned to have AC used to execute death row prisoners (the electric chair). He was, IMHO not a genius.

Elon Musk is, in my opinion, a bona fide genius. With a bachelors degree in physics, he taught himself rocket science, and was the chief designer of an entire rocket, the Falcon I. This rocket managed to put two objects in orbit before being superceded by the Falcon 9. The amount of information he must have learned is astounding. Fluid dynamics, combustion, orbital dynamics and trajectory control, metallurgy, each in and of itself an entire field of study. He also has a solid background in computer science.

So, I will give what Musk says on the future of transport quite a bit of weight. He has earned it.

cars might be able to park too close to open doors, meaning more cars could park in a given area

Also, cars could park directly head-to-tail. Then when a car three deep is summoned, it could signal the other two cars to move. The lanes through the lot could also be made much narrower. The capacity of parking lots could easily be doubled, and possibly tripled.

In some European cities, it is customary to leave your car parked in neutral and with no parking brake on (obviously on the flat). When someone wishes to park parallel park in a tight spot, they just nudge the cars in front or behind, causing them to roll, widening the spot. This allows cars to be parked "nose to tail".

What I notice in this photo (hi-res version) around the area of the shadow are the apparent shapes of the ice "boulders" that came together to form the comet in the first place. It reminds me of looking at chondrules in meteorites, that show the siliceous "hailstones" that formed as the planetary disc that would go on the form the planets cooled.

The Science of a Bottomless Pit 122

StartsWithABang writes It's the ultimate dream of many children with time on their hands and their first leisurely attempt at digging: to go clear through the Earth to the other side, creating a bottomless pit. Most of us don't get very far in practice, but in theory, it should be possible to construct one, and consider what would happen to a very clever test subject who took all the proper precautions, and jumped right in. Here's what you would have to do to travel clear through the Earth, come out the other side, and make the return trip to right back where you started.
