If you Google "Peak Oil" you'll see what it's probably all about.
www.lifeaftertheoilcrash.net seems to be one of the most popular sites about it. I think that was #1 in the Google results.
An analogy: When you have a leaf pile you're hauling off to the woods in barrels, you can fill that barrel pretty fast when the pile is still fresh. After you get past the halfway point in the pile, it takes you longer to fill the barrel, even though you still have half the leaves left. The smaller the pile gets, the longer it takes you to fill the barrel.
According to this info, oil fields are like that, too. Recent news reports have hinted that the world's oil supply is at that critical halfway point right now.
Do the Googling. The information isn't getting a lot of press because too many viewers care more about Britney Spears getting her life back together. If the predictions are true, then Boat gas is cheap now. There's gotta be a way to use lake algae or seagull poop for boat fuel.
Any engineers out there?
