It's not that Musk's dreams — introducing a mass-market electric car, colonizing space — are ignoble. Far from it. It's just that he lacks the means and the mindset to realize them.

Every dreamer must turn huckster at some point, lest his fantasies remain just that. But Musk is taking the practice to an extreme.

He is touring the United States, showing off a barely driveable show-car version of his Model S electric sedan, hoping to drum up deposits — sorry, "reservation fees" — on which his cash-strapped company will live until, in theory, it lands $350 million in government loans to build the car — maybe in 2011 but more likely in 2012, years after Musk first predicted his company would sell a mass-market sedan. If it happens at all. Musk has been treating the loans as a sure thing for months, but the company's application has yet to be approved.

If he cannot stop human motorists from polluting the planet, he will try to help them escape it through his other company, Space Exploration Technologies, or SpaceX. But SpaceX, too, seems to be running aground. The latest launch of his Falcon 1 rocket was cancelled, and the vehicle is rotting in the moist salt air of Omelek Island in Kwajalein while his technicians scramble to fix a vibration problem.

Aside from Falcon 1, Musk has no tested vehicles. The Falcon 9, the rocketship which Musk hopes will replace the Space Shuttle in carrying crew to the International Space Station, has not yet had its maiden flgiht. According to an archived SpaceX launch schedule, that was supposed to happen last year. An updated schedule shows that SpaceX's paying clients from Malaysia to Sweden have had their launches delayed, in some cases by years.

Musk's personal life is another source of unmanaged distraction. He is in the midst of a divorce from his wife, Justine Musk; the couple has five children. He is engaged to a British actress, the recently blonde Talulah Riley, whom he is supposed to marry this year. (That launch's schedule, too, has seemed to shift.)

Musk's underlings report a fickle, reality-resistant boss, flitting from idea to idea but never quite landing. And yet we're supposed to believe that Musk will get us to Mars by 2020 on the dot?

There's the real danger: Not that Musk's dreams are wrong, but that his personal failings mean it's more than likely he'll never realize them. Then the danger is that Musk's frothingly dizzy fanboys and orgasmically giggling fangirls will turn not just against Musk but against the dreams of electric cars and spaceflight. That's why, if you hope to zip around this rock without polluting it, or escape its gravity altogether, Elon Musk should not be your hero. The dream is not the dreamer.

Musk, the boss of and lead investor in the electric-car startup, was previously the cofounder of PayPal, a payments startup bought by eBay for $1.5 billion in 2002. So one would assume he's rolling in it. And cash for silence is the usual barter when the newly wealthy part ways with their first wives. But Justine Musk isn't taking that route. After reading a profile of Elon's current love interest, 23-year-old British actress Talulah Riley, who is 13 years her junior, she piped up:

When you are living part of your life in the public eye anyway — when you blog, when your divorce has been kicked out there for public consumption — when does this whole idea of "taking the high road" segue into this idea of being silent, silenced, even as someone appropriates your words to spin out a certain version of events?

Justine now disputes the notion, previously advanced by Elon, that the two were racing to the courthouse to file divorce papers. She says that she and her husband had completed all of three sessions of marital counseling when Elon gave her an "ultimatum":

"Either we fix [the marriage] today, or I will divorce you tomorrow."

The next morning, Justine found that her credit card had been cut off and thereby learned that he had gone ahead and filed for divorce. This is not the picture she painted last year of an amicable, mutual split.

The unraveling of the Musks' marriage appears to have happened in the space of a few short weeks in July. Elon met Talulah Riley, the star of St. Trinian's, in London on July 3. On July 18, Justine wrote about being "in the midst of some major drama." A week later, Riley escorted Elon to the opening of Tesla's auto showroom in Menlo Park. And soon afterwards, he proposed to her, Riley told the Daily Mail. A couple of weeks later, Justine wrote a biting blog entry about older men who date younger women:

I was thinking about the time a male friend, who is my age (mid thirties), and I had a bit of a spat in the driveway outside his lush hillside home. When I refused to buy into his argument and turned to go inside the house, I heard him say scornfully, "Yeah, that's it, go hang with the twenty year olds."

I thought: Dude, I'm not the one who's dating them.

Not that there aren't some mature early twentysomethings out there capable of dating anybody — just that his comment revealed more about men like him than any group of women. To wit: women that young are like children, and quality interaction happens between myself and fellow successful male peers. And yet that pool of "children" is where these same men go again and again to fish out the new girlfriend. Thus: my girlfriend is a child, but that's okay, because quality interaction happens elsewhere.

The next month, Justine went public with news of her divorce. She subsequently wrote:

We had a good run. We married young, took it as far as we could and now it is over. That's about all I can say for now, other than that it was a very sad and very necessary decision.

So why is she breaking her silence now? It could be her frustration with seeing her own words used to portray Elon as an honorable man who found a new love as his old one foundered. But it could also be that she has literally nothing to lose.

Acquaintances have been saying for some time that Elon is essentially broke, save for his illiquid stakes in Tesla Motors and SpaceX, his rocket-ship startup. We hear that he had to liquidate investments at a loss so he could participate in Tesla's most recent round of funding, and that he's couch-surfing with friends on his frequent trips from Los Angeles, where he lives, to Silicon Valley, where Tesla is based.

One hopes Riley and Musk really did bond over a mutual love of astrophysics.

Riley told the Daily Mail that she "fell in love with Elon because of our mutual love of physics." Perhaps it was "physiques." Those British accents are tricky. Justine Musk's comment on the 23-year-old Riley, in her LiveJournal: "She is not blonde, and I do find this refreshing."
