Good idea, not-so-good comparison
Researchers at Colorado State University began working on laser ignition for heavy-duty natural-gas engines back in 2002, and more recently Ford and the University of Liverpool in the U.K. have teamed up to develop a passenger-car application. Here’s how it works: A near-infrared laser beam shines through a lens that focuses the light at a particular point (or possibly at multiple points) in the cylinder, generating intense energy that causes the air molecules to ionize. This creates a plasma discharge (it looks like a spark formed in mid-air) that ignites the air-fuel mixture. Such plasma discharges form in as little as 100 nanoseconds (100 billionths of a second — about as long as it takes the federal government to spend $13).
Really? Thirteen bucks in 100 nanoseconds?
Let’s see. That’s $130 in a microsecond, therefore $130 million in a second, or $7.8 billion in a minute. Blow this up and you’re over $11 trillion in a day, beyond even Harry Reid’s wildest dreams.
The President submitted a budget, in the much-abused Washington definition of the word, calling for a mere $3.55 trillion in spending for fiscal year 2010. This works out to $9.72 billion a day, $405 million an hour, $112,000 a second — or eleven cents a microsecond. In 100 nanoseconds, the Feds manage to spend, not $13, but a little more than a penny. Yes, folks, it’s true: it’s possible to overestimate government expenditures.
Then again, I’ve been doing this site for thirteen years. By the time thirteen more years have passed, they might actually be spending $13 in 100 nanoseconds. I shudder to think what the marginal tax rate might be by then.

Forget the money. I’m still scared about the idea of lasers in the presence of natural gas.

When they can use a laser to cause explosive expansion of plain old air, that’s when we’ll be able to stop pumping sludge and sending dollars to desert kingdoms.

If those expenditures become commonplace, hundred dollar bills will be worth more as furnace fodder than actual cash.
