Eight hours of sleep in three. Guess I'll have more time to waste.

A marvellous invention might radically change our sleep cicles: the TSC.
This magnetic device apparently gives your brain a full night of rest in just three hours.
Other than a cure for insomniac and a solution for those of us who love nocturnal life this little gizmo might have greater repercussion than it appears... assuming of course it works as smoothly as the old eight hours of sleep we are abitued to.
Sleep isn't only necessary to the brain: our muscles need it to rest and to rebuild themselves, so I guess natural sleep will never be completely substituted... beside the human body is an incredibly complex machine; who knows what messing whit a not so little thing as sleep can cause?
An interesting view of the thing is given in Nancy Kress's sleepless trilogy...
What if this technology becomes accessible only to the wealthy? will those capable of affording such machine receive an unfair advantage over those unable to purchase it? Think about it: five more hours to work, to study, to train in sports... more than one fifth of a day of life per day.
Not to mention the catastrophic crush in the assumption of coffee.
Here is a link to the story.
I'm curious to hear your opinions on the matter. The crazier, the best.

Bye!
