Volunteers to begin Mars500 isolation. I love the psychological sides that this can bring. I expect that there is down time. The only communication with the outside is email, and an email has a 20 minute delay. I wonder if they are allowed anything for entertainment. I expect that cards would be useless with a more weightless environment. Can they use a Kindle? The e-ink lasts a lot longer and uses very little battery, it could provide a very small item that has limitless content to be read. Many books could be stored on it to start with, but new ones could also be emailed I would think.
I expect that there is also a power limit on what they can use. Has e-ink made it into any actual computing devices yet? I read an article the other day that showed a demo of it on a flexible screen showing color images. If it's not there yet, I expect that in the next 5 years that e-ink will be in use on some high end laptops with extreme battery life because the screen will use a lot less and the hard drive will be a solid state drive.
