New ‘sleep machine’ could signal the end of insomnia – DailyMail.co.uk: What happened to the good old days when people got drunk until they passed out? ;)
Imagine how useful this device could be in long range flights.

Scientists have invented a technique which they say could help trigger deep sleep in the most chronic insomniac.
Using medical equipment, they stimulated the brain with harmless magnetic pulses.
These penetrate the nerves that control a type of deep sleep called “slow-wave activity” and made their brains produce these waves.

Researchers believe the same principles could be used to create a machine which can electronically stimulate a deep-sleep power nap. This mimics the restorative benefits of eight hours of rest.

There, it activated electrical impulses. In response to each burst of magnetism, the sleeping volunteers’ brains produced slow waves typical of deep sleep. “We don’t know why, but this was a very good place (in the brain) to evoke big waves that clearly travel through every part of the brain.
