Mythbusters Revisit Week, It Would Seem

I found this article about how we can solve global warming by driving our cars closer to each other (drafting, like they do in racing). It would make the cars much more efficient by reducing drag. The scientists seemed so happy to present these new findings. They obviously don't watch Mythbusters [JessePedia] though, as they already did this experiment earlier this season, with similar results. It is indeed quite a fuel saver to drive within a foot or two of the car in front of you, but not practical and very dangerous.

Here's where these scientists step in with a solution: they would have us use automatic sensors to keep our cars a certain distance apart, but one has to wonder, how well do these sensors work when the car in front of you slams into another car or bridge abutment? I'm guessing not very well.

In other Mythbusters-related news, Ken Couch flew nearly 200 miles in the Pacific Northwest in a lawn chair this week, using only helium balloons. Mythbusters proved this unlikely last year, with thousands of standard-sized helium balloons... but this guy was using much larger balloons, as you can see in the photo on ABC's site and this photo from farther away. Mythbusters later revisited the myth, testing lifting a person with weather balloons, not much smaller than those Couch used, and decided that it was indeed possible.
