Bounties attract serious brainpower to the challenge.
- To see what happens and gain a better insight of what different hemispheres do.
- Come up with unexpected/good ideas with one hemisphere at a time. See this and this.
- Some professions require people to remain vigilant during the night (soldiers, guards, doctors, etc). Asymmetrical sleep on demand would come in handy for them.
- Sleep in new, unfamiliar environments every night for several months. Stealth camping comes to mind.
- Would it be possible to somehow chemically mildly sedate one hemisphere or stimulate the other?
- Reduce the temperature on one half of the brain via cold cap-like device - thereby locally slowing down the chemical processes.
- LED light eye patch covering one eye. In regular intervals turn on light stimulation.
- Headphone in one ear. In regular intervals disrupt the person's sleep with thought-provoking questions/ideas. Or just random sounds.
- Kinetic stimulation on one cheek, arm, leg.
- What else?
