Beware the vortex engines.

Another interesting post on the freakonomics blog. And again their commenters put you people to shame. Can I get a little vitriol around here?

I think this is the most ridiculous idea anyone has ever come up with. Has the world gone mad?

This blog post and comments may well be the most frenzied display of science illiteracy I have ever encountered in print.

I don’t understand how this would work, as potential temperature increases with height. Wouldn’t the air parcels lifted by the tornado cool adiabatically?

I had to look that one up.
