Interesting concept. You're basically creating a 30 character password containing only the 26 characters of the alphabet, as opposed to a 15 character password containing alphabet, numeric, and special characters.

The article points out that this method doesn't generate much more entropy than a 15 character password.

The resulting passphrase wouldn't be accepted by common password filters that require a combination of letters, numbers, and special characters.

A complex 15 character password can be generated (and remembered) by just coming up with a sentence that contains a couple strings of numbers and inserting special characters. Works for password filters and is easy to remember. Doesn't seem to me that memorizing a random set of words is any easier than creating a memorable sentence.

Add in the problem that most "hacking" is done by exploiting software flaws (including flaws in encryption processes) and it seems like this is a lot of work for very little gain.

Looks like a solution in search of a problem.
