|If you want to have 21 hours of awake time a day? The Da Vinci Alarm Clock let you follow da Vinci's 3.5 / .5 sleep schedule(a half hours awake, thirty minutes asleep) Designer Marc Owens explains his clock as follows: The Da Vinci Alarm Clock works on a very basic system. The Dot Matrix display will always show either Sleep or Awake. When the product is first switched on the display will immediately show the word Awake. This will continue to be displayed for 3 hours at 30 minutes. It just a concept.
The Da Vinci sleep schedule, also known as the "sleep of genius" or polyphasic sleep, is a type of sleep pattern which involves sleeping not more than 5 hours a day. Some experts are more strict, arguing that to follow the Da Vinci sleep schedule, a person must become accustomed to sleeping an average of two hours a day, which is how much Leonardo Da Vinci himself slept; others take the term more loosely, allowing practicants to sleep a few hours a night.
The Da Vinci sleep schedule is better suited to people who can control their daily schedules. Basically, the system requires followers to sleep in several 10-minute bursts, for a total of two hours a day. A variation of the Da Vinci sleep schedule requires people to sleep 20 minutes for every four hours that they are awake. This technique, known as "power napping" or the "Uberman's sleep schedule" is actually in use in many corporations as a way to up production of their employees.
