HonorPoncaCityDotCom writes "AP reports that while confined to the basement of a CIA secret prison in Romania about a decade ago, Khalid Sheikh Mohammed, the admitted mastermind of the 9/11 terrorist attacks, asked his jailers whether he could design a vacuum cleaner. After all KSM earned his bachelor's in mechanical engineering, the agency had no long-term plan for him, but might thought he might someday prove useful and might even stand trial one day and for that, he'd need to be sane. They were concerned that his long imprisonment might do so much psychological damage that he would no longer be useful as source for information. "We didn't want them to go nuts," said a former senior CIA official. So, using schematics from the Internet as his guide, Mohammed began re-engineering one of the most mundane of household appliances. It remains a mystery how far Mohammed got with his designs or whether the plans still exist and even Mohammed's military lawyer, Jason Wright, says he is prohibited from discussing his client's interest in vacuums. 'It sounds ridiculous, but answering this question, or confirming or denying the very existence of a vacuum cleaner design, a Swiffer design, or even a design for a better hand towel would apparently expose the U.S. government and its citizens to exceptionally grave danger,' says Wright. So now, says Doug Mataconis, if you happen to start seeing ads for the CIA's revolutionary new home cleaning device, you'll know where it came from." Sounds perfect for In-Q-Tel.
